    ____________________________________)
    Defendant Daniel Gary Landry was convicted by a jury of first degree
    murder (Pen. Code,1 § 187, subd. (a)), two counts of assault by a life prisoner with
    malice aforethought (§ 4500), and one count of custodial possession of a weapon
    (§ 4502, subd. (a)). Additionally, the jury found true allegations that defendant
    personally used a deadly and dangerous weapon in the commission of the offenses
    (former § 12022, subd. (b)(1)), and that he had suffered two prior strike
    convictions for first degree residential burglary (§ 459). (§ 1170.12, subds. (a)-
    (d).) Following a penalty trial, the jury returned a verdict of death. The trial court
    denied the automatic application to modify the verdict (§ 190.4, subd. (e)), and
    sentenced defendant to death. This appeal is automatic. (§ 1239, subd. (b).) For
    the reasons set forth below, we strike the one-year enhancement imposed on count
    1       All unspecified statutory references are to the Penal Code.

    I. FACTS
    A. Guilt Phase
    1. Prosecution Case
    a. Fatal Attack on Daniel Addis (Counts 1 and 2)
    In August 1997, defendant and the homicide victim, Daniel Addis, were
    inmates at the California Institution for Men in Chino and housed in the
    administrative segregation unit (ASU). That housing unit is reserved for inmates
    who present safety or management concerns, including inmates awaiting
    adjudication for violations of prison rules. Defendant, who was serving a sentence
    of 25 years to life under the “Three Strikes law”, was a member of a White
    supremacist gang called the Nazi Lowriders (NLR), as was his cellmate Gary
    Green. Defendant and Green were housed on tier 3 of ASU.
    Addis, who was not a gang member, had been placed in ASU for assaulting
    a staff member. He had previously been housed on tier 3, but in July, he had
    asked to be moved to another tier. He told the guard to whom he made the request
    that he had stolen tobacco from NLR gang members. Commission of this offense
    by one who was not a member of the gang would have resulted in retaliation from
    the gang. Addis was moved off tier 3 and eventually housed in a single cell on tier
    1 of ASU.
    Although Addis was housed on a tier different from defendant and other
    NLR members, he exercised in the same yard, one of four that were segregated by
    race and gang affiliation. The procedure for moving inmates from their cells to
    the exercise yards involved stringent security protocols. The yard was searched
    for weapons before any inmate was allowed to enter. In addition, the inmates
    2
    were subjected to repeated searches before they were allowed into the yard. These
    included a visual strip search in their cells, passing through a metal detector, a
    hand search of their person and effects and a final search by a hand-held metal
    detector before they were admitted to the yard one at a time. As part of the strip
    search, they were required to squat and cough to determine if they were trying to
    smuggle contraband in their rectums. Once allowed into the yard, inmates were
    required to line up against the fence until all inmates were in the yard.
    Correctional officers in the guard tower could observe all four exercise yards.
    On Sunday, August 3, 1997, all of the White inmates, except Addis, had
    entered their exercise yard. Defendant‟s cellmate, Gary Green, who was a “shot
    caller” and leader of the NLR gang, started yelling at the gate guard, Rosamaria
    Maldonado, to let Addis out into the yard. Inmates were subject to monthly
    classification reviews to determine, among other matters, whether they were
    eligible for the yard. If they were eligible, each decided whether to avail himself
    of the yard privilege. Addis was eligible to go into the yard and had done so the
    previous Thursday without incident.
    Maldonado went to her superior, Sergeant Arioma Sams, and told him the
    other inmates were demanding that Addis be brought out into the yard. Sams
    testified that he checked the yard for unusual activity but did not observe any.
    Timothy Ginn, another guard on duty that day, testified he told Sams that if Addis
    went out into the yard he might get “beat up.” Sams replied that their hands were
    tied because Addis had a right to go into the yard if he wanted to. Ginn told Addis
    “you don‟t have to go if you don‟t want to.” Addis replied, “Fuck that. I want to
    go.” Laramie McAlmond, another guard, testified that she overheard Ginn‟s
    conversation with Addis and confirmed that Addis said he wanted to go out to the
    yard. She testified that Addis said, “Everything‟s squashed,” which is prison slang
    for everything is settled and there are no problems.
    3
    Addis was released into the yard at 9:30 or 9:45 a.m., about 30 to 45
    minutes after defendant and Green had entered the yard. Officer Frank Esqueda,
    one of the two tower guards on duty, testified that Addis joined the other inmates
    in exercises, and then walked around and talked to a few inmates. Esqueda
    observed Green and defendant walking back and forth and talking, but despite the
    fact that Green had demanded that Addis be brought out, Green initially ignored
    Addis. Green acknowledged Addis at 11:15 a.m., when the showers typically
    were turned on. Green and Addis were standing by the showers, and Green shook
    his hand and told him, “It‟s all right, Danny. Go ahead and play cards.” Addis
    then walked to a card table and sat down to play pinochle with other inmates.
    About 10 or 15 minutes later, Green and defendant walked from the showers to the
    table, talking back and forth. When they arrived at the table, defendant stood to
    the left of Addis, and Green stood to the left of defendant. One or two minutes
    later, Esqueda saw defendant make a sudden movement with his left hand to
    Addis‟s neck.
    Another inmate, Ricky Rogers, who was playing at the same table, also
    observed defendant approach and stand behind Addis. Rogers testified that
    defendant and Addis had a friendly conversation about a third inmate. Rogers saw
    defendant raise his arm “real fast,” and then heard a sound like a punch. Addis
    stood up from the table and put his hand to his neck. When he pulled his hand
    away, blood was streaming from his neck. He dropped to his knees and then fell
    over.
    From the tower, Officer Esqueda also saw Addis reach for his neck and saw
    blood flowing from it. Esqueda ordered the inmates in the yard to get down on the
    ground. Everyone complied except defendant and Green, who continued running
    across the yard. Defendant and Green complied only after Esqueda fired a “gas
    launcher” that shot a wooden baton block into the yard. When defendant went on
    4
    the ground, a weapon popped out of his left hand and landed in front of him. At
    trial, the weapon was described as a stabbing instrument consisting of a sharpened
    piece of metal covered by a sheath made from cellophane and cardboard and
    wrapped with string.
    Addis was removed from the yard bleeding profusely, and died en route to
    the hospital. An autopsy established the cause of death was massive blood loss
    caused by the severance of his jugular and subclavian veins. A great deal of force
    was required to inflict the fatal wound.
    After Addis was removed from the yard, correctional officers cleared it of
    the inmates one at a time. The inmates remained prone until they were removed.
    Defendant‟s left hand and the stabbing instrument found near his hand were
    bloody. Defendant was giggling and laughing as he lay on the ground. Later he
    was examined and photographed. He had blood on his left hand and boxer shorts,
    but was uninjured. The stabbing instrument recovered near defendant was
    consistent with a weapon that would inflict the fatal wound Addis received.
    Ten days after defendant attacked Addis, he threatened to flood the tier
    where he was housed unless he was moved. The officer to whom he made the
    statement told him he could not be moved because of the ongoing investigation
    into Addis‟s killing. Defendant replied, “I killed him so I confess. The
    investigation is over.”
    Defendant wrote two letters, one dated September 9, 1997, and the other
    September 22, 1997, to Joseph Lowery, another NLR member imprisoned at
    Corcoran State Prison. Glen Willett, a prison gang expert testified that
    defendant‟s use of certain phrases identified him as an NLR gang member and that
    other references were to the Addis homicide. The letters are described more fully
    below in connection with defendant‟s challenge to the letters‟ admission into
    evidence. (See post, pp. 34-40.)
    5
    b. Attack on Joseph Matthews (Count 3)
    On September 18, 1997, Officers Lourenco and Perez were escorting
    inmate Joseph Matthews from the showers to his cell when defendant called out
    from his cell, “Joe, want a cigarette.” Matthews broke away from the officers and
    ran toward defendant‟s cell. Matthews, whose hands were cuffed behind his back,
    turned his back toward defendant‟s cell door and put his hands at the porthole
    opening of the door, reaching for something. Neither officer saw any object being
    transferred. A moment later, Matthews stepped away and said, “I‟m cut.”
    Matthews‟s back was bleeding from a deep gash 7 to 8 inches long and three-
    quarters of an inch wide. Within seconds after Matthews stepped away from the
    cell door, the officers heard the sound of defendant flushing the toilet. It was
    impossible to retrieve items flushed down the toilet, but Jeffrey Killian, a medical
    technician on the floor, testified that Matthews‟s wound was inflicted with a razor.
    Fourteen stitches were required to close Matthews‟s wound. Three weeks after the
    attack, Matthews told an investigator that defendant had pulled out a razor blade
    attached to a toothbrush which he used to attack Matthews, and then flushed the
    razor down the toilet.
    c. Custodial Possession of a Weapon (Count 4)
    On October 15, 1997, officers entered defendant‟s cell, of which he was the
    sole occupant, to allow him out of the tier to exercise. When Officer Lopez
    opened defendant‟s cell door, a sharp metal object fell to the floor. Defendant
    smiled and shrugged. The object was a one-inch long piece of metal, shaped like a
    dagger and known in prison as a “spearhead.” In a subsequent search of the cell,
    officers also recovered a razor blade that had been removed from the disposable
    razors given to inmates for shaving.
    6
    2. Defense Case
    The defense conceded defendant‟s guilt on counts 3 and 4, the attack on
    Matthews and the possession of a weapon, and focused its efforts on counts 1
    and 2, the killing of Addis. With respect to the attack on Addis, the defense
    argued that defendant acted out of duress because he himself would have been
    killed if he had not attacked Addis as ordered by Green and the NLR. As a
    corollary, he maintained that the prison guards knew Addis was going to be
    attacked and allowed it to happen in retaliation for Addis‟s assault on a prison
    guard, thus foreclosing defendant from obtaining protection from prison
    authorities. Defendant sought to establish his defense through the testimony of
    Officer Rosamaria Maldonado, the guard who had expressed concern about
    Addis‟s safety to Sergeant Sams, and two prison experts. Defendant himself did
    not testify.
    By the time Rosamaria Maldonado testified, she had left the Department of
    Corrections after filing a stress claim seeking workers‟ compensation benefits. In
    that claim, she cited the Addis killing, among other incidents, as contributing to
    her stress. With respect to the events of August 3, 1997, she testified that Green
    had been insistent that Addis come out to the yard. She thought Addis might have
    safety issues if he went out to the yard, and she told Addis, “You must be packing
    for them because they‟re dying to see you.” By this, she meant that Addis must be
    concealing drugs or weapons. He looked at her and smiled and she let him out
    into the yard. After releasing Addis into the yard, Maldonado observed that Green
    merely nodded and did not greet Addis as he usually did, with a hug and a kiss.
    When Maldonado walked back into the building, she told Sergeant Sams, “You
    know, Sarge, they‟re going to take him out.” Sams responded, “Come on, we got
    a lot of work to do.” She and Sams left the area to conduct cell searches. About
    two hours later, she heard a gas launcher in the exercise yard. She was one of the
    7
    officers who responded to the yard to help Addis. In addition, after he was carried
    out of the yard on a stretcher, she rode in the ambulance with him. Addis died as
    she was performing CPR on him.
    At trial, Maldonado denied the existence of any conspiracy between the
    guards and Green to kill Addis, and denied that her fear for Addis‟s safety was
    anything other than a “gut feeling.” She had previously been unaware that Addis
    had been placed in ASU because he had hit a guard. However, according to Dr.
    David Friedman, from whom she sought counseling, Maldonado told him that they
    knew “an inmate was to be killed. We all knew it. I told the supervisor that he
    would be killed if we let him out of his cell.” She also told Dr. Friedman that she
    had told her sergeant, “They are going to kill him.”
    Confronted with these statements at trial, Maldonado claimed that
    Dr. Friedman had paraphrased what she told him, and that she did not make the
    statements he attributed to her. She denied telling him “I tried to stop it,” or that
    “They killed him because they thought he was giving information to us, which he
    was. He used to talk to [Officer] Kaffenberger a lot.” She similarly testified that
    statements attributed to her by Dr. Donald Feldman, who examined her in
    connection with her workers‟ compensation claim, were also paraphrases. In the
    statements attributed to her by Dr. Feldman, she allegedly said she had told
    Sergeant Sams an inmate was likely to be killed if they let him out of his cell, and
    that Sams had shrugged.
    The defense also called as a witness James Gleisinger, who assisted
    Freidman in worker‟s compensation evaluations. Gleisinger testified that he
    interviewed Maldonado and set forth in his report Maldonado‟s verbatim
    statements to him. Among the statements in his report were: “ „She recalls “the
    most dramatic thing was about 18 months ago an inmate was to be killed. We all
    knew it. I told the supervisor that he would be killed if we let him out of his
    8
    cell,” ‟ ” and “ „ “That inmate was let out even though everyone knew he would be
    killed if he was let out. I tried to stop it. That could open up a big can of worms.
    I told my sergeant that they‟re going to kill him. [¶] „She states that Sergeant
    Sams “shrugged his shoulders.” ‟ ”
    Two prison experts testified for the defense. Steven Rigg, a 17-year
    veteran of the Department of Corrections, from which he had retired in 1998 as an
    acting captain, reviewed materials relevant to the attack on Addis and testified that
    the guards had repeatedly mishandled the situation. In Rigg‟s opinion, Green
    should have been removed from the yard and disciplined for causing a disturbance
    by demanding that Addis be brought out. Rigg also testified that the guards
    should have known Green‟s demand that Addis be brought to the yard indicated
    trouble because Addis was not an NLR member and had been moved to a different
    tier under circumstances that showed he was in trouble with the NLR. The fact
    that Addis had stolen tobacco and “rolled off the tier” put him at risk. Rigg
    testified that once Maldonado informed Sergeant Sams that “they‟re going to take
    him out,” the tower guard should have been instructed to remove Addis from the
    yard. According to Rigg, the fact that Addis was yard eligible should not have
    prevented Sams from removing him from the yard once he received information
    that Addis might be assaulted or killed. Rigg further testified that Green‟s initial
    failure to greet Addis, followed by his attempt to engage him, showed a “setup.”
    Under those circumstances, the tower guard should have ordered the inmates to
    the ground and searched for weapons when he saw Green and defendant approach
    Addis as he was playing cards.
    Rigg also testified about prison gangs generally. According to Rigg, if a
    gang member received an order from a gang leader to carry out an assault, he was
    expected to do so. If he failed, the inmate would put himself at risk to be assaulted
    or killed. Further, after carrying out the assault, the gang would expect the inmate
    9
    not to show any concern for the victim. To do so would be considered a sign of
    weakness.
    Applying these observations to defendant‟s situation, Rigg opined that, had
    defendant failed to assault Addis, he would have been “a walking dead man.” He
    could not have obtained assistance from the correctional staff without requesting
    protective custody, and even in protective custody, inmates have been assaulted
    and killed. Moreover, Rigg testified, the sequence of events showed that Sergeant
    Sams “possibly wanted [Addis] assaulted,” in that Sams failed to take action to
    protect Addis. Furthermore, the light administrative punishment imposed on
    Green for his involvement in the attack — a 360-day credit loss without a term in
    ASU — showed, in effect, that the Department of Corrections “did not punish him
    for being involved in the conspiracy as charged, yet they found him guilty.”2
    Anthony L. Casas also testified as a prison expert. Casas had worked for
    over 22 years in the Department of Corrections, retiring as associate warden at San
    Quentin. He was particularly involved in dealing with prison gangs. Casas
    testified that inmates become involved in prison gangs in various ways. A gang
    may offer a new inmate protection in return for which the inmate will be expected
    to do the gang‟s bidding. If the inmate refuses, the gang will tell him he cannot
    disrespect the gang after it helped him. While some inmates who are big and
    2       Sergeant Sams accused Green of involvement in a conspiracy to assault
    Addis, and of ordering the “hit” on Addis. The hearing officer found the
    allegations to be true. On Ocrober 10, 1997, Green was given a warning and a
    reprimand, and was assessed 360 days of credit. He was also referred to the
    institutional classification committee for a program review and to the Bureau of
    Prison Terms (now Board of Parole Hearings) regarding his rule violation.
    Sergeant Sams did not recommend that Green be given a term in a security
    housing unit or any other special type of confinement. Green was paroled on
    October 30, 1997, 20 days after this punishment was imposed.
    10
    strong may be able to avoid gangs, someone like defendant, who is five feet six
    inches tall, and then weighed 150 pounds, might need the gang‟s protection.
    Additionally, an inmate serving a long prison term will do what he can to be
    protected in prison.
    Casas testified that with most gangs, the only way out is death. If a gang
    orders a member to commit a crime and he fails to do so, “[h]e can easily be
    killed. As a matter of fact, in most cases where your gangs are disciplined enough,
    that‟s precisely what happens . . . . You follow or you‟re gone.” Once an inmate
    has carried out an order to commit an assault, he is expected to show pride and
    brag about the crime. Any show of regret would be seen as a sign of weakness,
    and the inmate could be thrown out of the gang or killed. Casas testified further
    that inmates observe staff. Based on his review of how staff handled Addis, Casas
    opined that an inmate would have concluded it was useless to rely on staff for
    safety.
    Like Rigg, Casas criticized the staff‟s handling of the situation in this case.
    He agreed that once Sams had been warned by Maldonado about the danger to
    Addis, Addis and Green should have been removed from the yard and an
    investigation should have been conducted. Like Rigg, Casas testified that Addis‟s
    yard eligibility would not have prevented Sams from removing him from the yard
    once Sams learned of the threat to Addis‟s safety.
    B. Penalty Phase
    1. Prosecution Case
    The prosecution‟s penalty case in aggravation relied on multiple incidents
    of prior criminal activity by defendant involving “the use or attempted use of force
    or violence or the express or implied threat to use force or violence.” (§ 190.3,
    factor (b).) To that end, the prosecution presented evidence that, while in prison,
    11
    defendant had committed multiple stabbings and attempted stabbings, and assaults
    on staff. It also presented evidence of numerous instances of assault and of
    possession of a weapon, all of them independent of those in the current case,
    including eight occasions on which he possessed a weapon, four instances of
    stabbing another inmate and one attempted stabbing of another inmate, a battery
    on an officer, and an assault on a staff member.
    Additionally, the prosecutor‟s cross-examination of a defense witness
    brought out details of defendant‟s juvenile criminal record, which included two
    theft-related charges. The same witness also testified that when defendant was 19
    years old, he pleaded guilty to three counts of residential burglary, one count of
    second degree burglary, and one count of grand theft of an automobile. In the
    same proceeding, six other theft-related counts were dismissed. Defendant was
    committed to the California Youth Authority for these offenses. The jury also
    heard about defendant‟s plea to one count of escape from the California Youth
    Authority, after which he was transferred to an adult prison.
    2. Defense Case
    As described by defendant in his appellate briefing, the defense case in
    mitigation “chronicled [defendant‟s] physical, sexual, and mental abuse as a child
    and the long-term consequences of those experiences, including posttraumatic
    stress disorder, multiple suicide attempts, schizoid personality disorder and bipolar
    disorder. [Defendant] also presented evidence that his criminal activity in state
    prison resulted from the denial of adequate mental health care and treatment by
    prison staff.”
    Testimony regarding defendant‟s family history was provided by his two
    maternal aunts, his maternal grandparents and his father. Both of defendant‟s
    parents were deaf. His mother, Linda, was described as having severe “mental
    12
    problems” that manifested themselves in the out-of-control behavior she displayed
    beginning in adolescence. For example, between the ages of 11 and 13, she set “a
    lot” of fires, including to the garage and to curtains in the living room. She once
    threatened one of her sisters with a knife. Later, she attacked a pregnant neighbor
    with a knife while the woman was showering and her husband was mowing the
    lawn. After that incident, she was removed from her parents‟ home and lived in a
    series of foster homes.
    Linda married Gary Landry when she was 20 or 21. Their marriage was
    marked by constant fighting over what Gary perceived as Linda‟s deficiencies as a
    wife and a mother. When Gary learned that Linda was having affairs with women,
    he painted “bad wife” and “bad mother” on the walls of their residence. Linda
    drew graphic pictures of women having sex with each other on the walls above
    defendant‟s crib.
    Neither parent nurtured or provided the basic necessities to defendant when
    he was an infant and toddler. Gary was a hard worker, but when he got home
    from work, he ignored defendant and instead spent time with his friends in the
    garage. Linda was a drug user and extremely neglectful mother. When members
    of her family would visit, they would discover defendant alone in his play pen,
    hoarse from crying and yelling. No one had responded to his cries. Linda‟s
    family installed a light-flickering system to alert her when defendant was crying.
    The house was filthy and defendant crawled on a floor littered with broken glass
    and curdled milk. When he was old enough to walk, defendant would get out of
    his crib and wander the neighborhood. His grandparents, who lived nearby, once
    discovered him asleep beneath their car. Another time, he was found scavenging
    for food in the neighbor‟s garbage cans.
    When defendant was four years old, he went to live with his grandparents.
    A year later, his mother regained custody, but a few months later she returned him
    13
    to her parents permanently. When defendant first went to live with his
    grandparents, he did not talk, but grunted and pointed. He had nightmares and
    hoarded food beneath his bed. When he returned to his grandparents, they took
    him to mental health professionals because he seemed inaccessible. He continued
    to receive psychiatric care, including hospitalization, throughout his childhood and
    adolescence.
    Nonetheless, defendant had problems outside the home, starting with being
    disruptive in kindergarten. He was repeatedly suspended in high school. At 15
    years old, he and a friend burglarized the friend‟s house. When he was 16 or 17
    years old, he stole a car, after which he entered the juvenile justice system and
    never again lived with his grandparents. He spent the rest of his adolescence at
    various juvenile camps from which he periodically attempted to escape. During
    this period, defendant was diagnosed as suffering from atypical depression and
    attention deficit hyperactivity disorder, for which he was medicated. It also
    emerged during his interviews with mental health professionals that he had been
    sexually abused by his father‟s best friend and by a friend of his mother‟s.
    Defendant was described by these mental health professionals as depressed and
    suicidal. All of these issues were related to the trauma he suffered in his first four
    years.
    Defendant‟s adult criminal history began when, at 19 years old, he pleaded
    guilty to three counts of theft-related first degree residential burglary, one count of
    grand theft auto, and one count of second degree commercial burglary. In lieu of
    prison, he was sent to the California Youth Authority where he was evaluated by
    James Cueva, a casework specialist, who testified at defendant‟s trial. According
    to Cuevas, defendant was depressed and suicidal, and had no goals, plans, or
    expectations for life. Cuevas recommended intensive treatment for defendant to
    address his severe mental and emotional problems.
    14
    Dr. Joseph Lantz, a clinical psychologist, interviewed and tested defendant.
    He reviewed statements by defendant‟s aunts and spoke to his grandparents.
    Lantz testified that defendant‟s early years were akin to those of “a feral child,”
    and produced the mental problems that plagued him into adulthood. He diagnosed
    defendant as suffering from “schizoid personality disorder,” which is characterized
    by a “marked detachment from relationships.” Victims of this disorder prefer
    solitude to human contact and are easily manipulated by other people. Lantz
    testified that, despite defendant‟s history, he was not “a character[o]logically
    violent person.”
    Dr. Frank Gawin, a psychiatrist, reviewed defendant‟s medical records and
    concluded that defendant suffered from bipolar disorder. He testified that prison
    officials were well aware that defendant suffered from this disorder as well as
    other emotional and psychological problems. Both defendant‟s grandmother and
    defendant himself had written to prison officials and elected officials requesting
    treatment for his mental health issues. According to Gawin, any treatment
    defendant received was “entirely inadequate.”
    Dr. Glenn Lipson, a forensic psychologist, testified about inmate mental
    health services in general, as well as defendant‟s particular case. He met with
    defendant and also reviewed records related to his mental health and treatment in
    custody. Lipson concluded defendant suffered from schizoid personality disorder
    and bipolar disorder. He testified that prison aggravated defendant‟s mental
    disease, and he attributed defendant‟s acts of violence in prison to the “diathesis-
    stress model” of behavior, i.e., the violent and stressful atmosphere of
    incarceration pushed defendant, who already suffered from mental illness, “over
    the edge.” Based on his review of defendant‟s prison records, Lipson testified that
    the treatment defendant received failed to meet the standards required for inmate
    mental health services.

    Finally, Anthony Casas, who had testified at the guilt phase, returned at the
    penalty phase to testify about conditions at Calipatria State Prison where
    defendant‟s first violent actions occurred. He testified that prison was staffed by
    inexperienced guards and less-than-qualified supervisors. The prison developed a
    reputation as being violent and out of control. Casas also testified that in 2000 he
    attempted to broker a deal in which defendant would provide information about
    the NLR to prison officials, but the officials concluded his information was stale.
    A similar deal with the Federal Bureau of Investigation failed to materialize
    because the San Bernardino District Attorney declined to participate.
    II. GUILT PHASE CLAIMS
    A. Review of Sealed Records
    1. Introduction
    Defendant requests that this court review certain records to which the trial
    court denied him access in whole or in part following an in camera review, and
    determine whether the trial court abused its discretion in denying him discovery of
    those records. The records fall into three categories: (1) the confidential
    correctional inmate files maintained by the Department of Corrections for Daniel
    Addis, Gary Green and defendant himself (the C-files); (2) the personnel files of
    Correctional Officers Esqueda, Sams and Maldonado; and (3) additional medical
    and personnel files of Officer Maldonado pertaining to her medical retirement
    from the Department of Corrections.
    2. Background
    a. C-files
    Before trial, defendant served a subpoena duces tecum on the Department
    of Corrections, in which he sought his own C-file. (§ 1326.) Thereafter, he filed a
    pretrial motion for discovery in which he requested, among other things, the C-
    16
    files for Green and Addis. (§ 1054 et seq.) Defendant argued that discovery of the
    C-files was necessary for him to determine whether the hearing officer who
    conducted Green‟s rules violation hearing arising out of his participation in the
    assault on Addis had relied upon “undisclosed sources.” He contended the files
    might (1) contain information to support his duress defense; (2) lead to evidence
    that correctional staff knew, or should have known, about the attack on Addis; and
    (3) disclose whether there were any internal investigations regarding the attack on
    Addis and if any correctional staff had been disciplined as a result of such
    investigations.
    The Attorney General, representing the Custodian of Records for California
    State Prison at Corcoran, moved to quash the subpoena or, alternatively, for the
    court to conduct an in camera hearing to determine whether the files should be
    disclosed. The Attorney General argued that the files were presumptively
    privileged, and disclosure of them would be contrary to the public interest. (See
    Evid. Code, § 1040, subd. (b)(2) [a public entity may refuse to disclose
    confidential information if “[d]isclosure of the information is against the public
    interest because there is a necessity for preserving the confidentiality of the
    information that outweighs the necessity for disclosure in the interest of justice”].)
    He asserted the discovery request was overbroad, and cited the need to protect
    individuals, such as informants, who would be endangered if their identities were
    disclosed. He further noted that if informants‟ identities were not kept
    confidential, inmates would be reluctant to cooperate in investigations. Finally, he
    urged that to protect the privacy rights of prisoners, confidential information
    regarding prisoners should not be released indiscriminately.
    The trial court agreed to examine the three C-files in camera before trial to
    determine what, if anything, in them was discoverable. Following its review, the
    court granted defendant partial access to all three C-files, most extensively those
    17
    of Green, and to a lesser extent, defendant‟s own file. It disclosed a single page of
    Addis‟s file. During trial, defendant renewed his request to examine Addis‟s file
    after the prosecution turned over to him an incident report detailing Addis‟s
    assault on a correctional officer. The trial court denied the request.
    b. Officer Personnel Records
    By subpoena duces tecum and an accompanying discovery motion,
    defendant sought the personnel files of 14 correctional officers. Defendant sought
    material from the files reflecting: (1) lack of credibility;
    (2) “dishonesty/untruthfulness/veracity/false arrest/conduct unbecoming an
    officer/neglect of duty”; and (3) acts of moral turpitude. The Attorney General,
    representing the California Department of Corrections, moved to quash the
    subpoena. The trial court preliminarily granted the discovery motion as to
    Officers Esqueda and Maldonado and Sergeant Sams. It denied the request for the
    personnel files of the remaining 11 officers based on defendant‟s failure to meet
    the threshold requirement of good cause for disclosure of police personnel records.
    (See Evid. Code, § 1043, subd. (b)(2); Garcia v. Superior Court (2007) 
    42 Cal. 4th 63
    , 70-71.)3 The trial court later reviewed the personnel files of Esqueda,
    Maldonado and Sams and concluded they contained no discoverable material.
    c. Records Related to Officer Maldonado’s Retirement
    After the trial had commenced, the prosecutor informed defense counsel
    that Officer Maldonado had retired a year after the assault on Addis because of
    “significant emotional and mental health issues” arising from her involvement in
    that incident. Defendant then served subpoenas on the State Compensation
    3      On appeal, defendant does not argue the trial court erred in concluding he
    had failed to show good cause for the personnel records of the other 11 officers.
    18
    Insurance Fund (SCIF) and the California Institution for Men (CIM), seeking
    records related to Maldonado‟s retirement from the Department of Corrections.
    The Attorney General, representing the California Department of Corrections,
    opposed the discovery request, arguing that the records were part of Maldonado‟s
    police personnel files as to which the court had already found no discoverable
    material.
    The trial court conducted a hearing on the motion. It stated it had received
    records from SCIF and CIM related to Maldonado‟s retirement. Additionally, the
    records of Dr. Friedman, the psychiatrist who examined Maldonado in connection
    with her retirement, were produced by Dr. Friedman in response to a defense
    subpoena. Following an in camera review of the records, the court allowed
    counsel for both parties to copy any records from the Friedman file they found
    relevant. It denied the discovery motion as to the SCIF and CIM records, finding
    there was nothing relevant in those records that was not also contained in the
    Friedman file. Defendant later sought to discover records of an investigation into
    Maldonado‟s workers‟ compensation claim made by an entity called Singleton
    Investigations at the request of the SCIF. The trial court reviewed the records and
    found nothing discoverable.
    3. Discussion
    Evidence Code section 1040, subdivision (b)(2), authorizes the trial court to
    decline to disclose confidential records maintained by a public entity when it finds
    “the necessity for preserving the confidentiality of the information . . . outweighs
    the necessity for disclosure in the interest of justice.” (See People v. Suff (2014)
    
    58 Cal. 4th 1013
    , 1059; People v. Avila (2006) 
    38 Cal. 4th 491
    , 606.) This
    provision is applicable to prison inmate records. (Ochoa v. Superior Court (2011)
    
    199 Cal. App. 4th 1274
    , 1281.) As the Ochoa court observed, the state has a valid
    19
    interest in maintaining the confidentiality of such records to “(1) protect
    individuals, including informants inside and outside of prison, (2) ensure
    institutional security, and (3) encourage candor and complete disclosure of
    information concerning inmates from both public officials and private citizens.”
    (Id. at p. 1280.) In addition, disclosure of police personnel records requires a
    threshold showing of good cause after which the trial court “screen[s] law
    enforcement personnel files in camera for evidence that may be relevant to a
    criminal defendant‟s defense.” (People v. Mooc (2001) 
    26 Cal. 4th 1216
    , 1225.)
    In either case, the trial court‟s ruling is reviewed for abuse of discretion. (Avila, at
    p. 607 [no abuse of discretion where trial court withheld access to a witness‟s
    parole records]; People v. Hughes (2002) 
    27 Cal. 4th 287
    , 330 [“A trial court‟s
    ruling on a motion for access to law enforcement personnel records is subject to
    review for abuse of discretion”].)
    Defendant asks that we review all records not disclosed to him by the trial
    court — the C-file records of defendant, Addis and Green, the personnel records
    of Officers Esqueda and Maldonado and Sergeant Sams, and the files of SCIF,
    CIM and Singleton Investigations related to Maldonado‟s retirement — and assess
    whether the trial court‟s rulings were proper. “Parties who challenge on appeal
    trial court orders withholding information as privileged or otherwise
    nondiscoverable „must do the best they can with the information they have, and
    the appellate court will fill the gap by objectively reviewing the whole record.‟ ”
    (People v. Price (1991) 
    1 Cal. 4th 324
    , 493.) We have reviewed the record and
    conclude that the trial court did not abuse its discretion in rejecting disclosure of
    the materials.
    We also conclude that the trial court‟s inadvertent failure to provide
    defendant with one document from Addis‟s C-file did not require the court to
    allow defendant to review Addis‟s entire C-file. As noted above, during trial,
    20
    defendant renewed his request for access to Addis‟s file after the prosecution
    turned over to the defense an incident report regarding Addis‟s assault on a
    correctional officer. According to the prosecution, it had obtained the document
    from the person who investigated the assault by Addis, but the prosecution
    apparently did not realize the document was relevant until it heard defendant‟s
    opening statement, which reflected a theory that correctional officers were
    complicit in the attack on Addis. Because the trial court had also failed to disclose
    the document, the defense asked to be allowed to review Addis‟s entire C-file to
    see if it contained other relevant documents. The trial court responded that it had
    reviewed the file two more times, “page by page,” and had discovered that the
    incident report at issue had been attached to a different report that involved a
    different incident. The court further stated that it found no other documents that
    were discoverable, and it denied defendant‟s request. We find no abuse of
    discretion in the court‟s decision and, as noted above, we have reviewed the file
    and found no discoverable documents.
    Finally, defendant requests that the court allow appellate counsel to review
    Addis‟s C-file in accordance with appellate counsel‟s duty to “preserve evidence
    that comes to the attention of appellate counsel if that evidence appears relevant to
    a potential habeas corpus investigation.” (Cal. Supreme Ct., Supreme Court
    Policies Regarding Cases Arising from Judgments of Death (2008) policy 3, std.
    1-1.) We decline his request. The files are preserved in the appellate record.
    B. Denial of Motion to Sever Counts
    Defendant contends the trial court abused its discretion in denying his
    motion to sever counts 1 and 2 (the attack on Addis) from counts 3 (the attack on
    Matthews) and 4 (possession of a weapon by an inmate). He further contends the
    denial of severance violated his rights to due process, a fair trial, a trial by jury,
    21
    and reliable capital case proceedings. (U.S. Const., 5th, 6th, 8th, & 14th Amends.;
    Cal. Const., art. I, §§ 7, subd. (a), 15, 16, & 17.) His contentions are without
    merit.
    In the trial court, defendant argued that separate trials were required
    because (1) there was an absence of cross-admissible evidence between counts 1
    and 2 (the killing of Addis) and counts 3 and 4 (the attack on Matthews and the
    custodial possession of a weapon); (2) the evidence supporting counts 3 and 4 was
    weaker than the evidence supporting counts 1 and 2; (3) consolidation would
    inhibit defendant‟s willingness to testify with respect to counts 1 and 2; (4) the
    Eighth Amendment required heightened scrutiny of joinder because counts 1 and 2
    rendered him death eligible; and (5) judicial economy would be served by separate
    trials because counts 3 and 4 involved distinct incidents and distinct evidence. At
    defendant‟s request, the trial court also considered an in camera offer of proof
    regarding defendant‟s testimony and how consolidation might affect his
    willingness to testify.
    In denying the motion, the trial court found that defendant had failed to
    make an adequate showing of a substantial danger of prejudice. The court found
    further that “the four charges involved conduct by the defendant while in prison in
    the California Institution for Men within a two-month period. Each occurred at
    [the] Palm Hall unit of [the] California Institute for Men. [¶] The offenses are of
    the same class of crime, either assaultive conduct by a prisoner or the possession
    of a prison-made weapon necessary to commit similar assaults. Each of the
    offenses involved prison-made weapons. Each of the assaults [was] committed
    with prison-made weapons against fellow prisoners. None of the charges appear
    to be weak in relation to the other. And the prejudice to the defendant would be
    small.”
    22
    The joinder of charges is addressed in section 954: “An accusatory
    pleading may charge two or more different offenses connected together in their
    commission . . . or two or more different offenses of the same class of crimes or
    offenses, under separate counts . . . ; provided, that the court in which a case is
    triable, in the interests of justice and for good cause shown, may in its discretion
    order that the different offenses or counts set forth in the accusatory pleading be
    tried separately or divided into two or more groups and each of said groups tried
    separately.” The legislative preference for consolidation under either of the two
    circumstances set forth in section 954 is intended to promote judicial efficiency.
    (People v. Capistrano (2014) 
    59 Cal. 4th 830
    , 851.)
    Defendant presents two theories of error. First, he contends count 4 was
    not properly joined with the first three counts because count 4, custodial
    possession of a weapon, did not involve assaultive conduct, and therefore was not
    of the same class as count 1 (premeditated murder) and counts 2 and 3 (assault by
    a life prisoner). Second, he contends the trial court abused its discretion in
    declining to sever counts 1 and 2, which arose from the assault on Addis, from
    counts 3 and 4, which arose from the assault on Matthews and the possession of a
    weapon.
    Joinder of the four counts was proper because the counts were all of the
    same class. “Offenses of the same class are offenses which possess common
    characteristics or attributes.” (People v. Smallwood (1986) 
    42 Cal. 3d 415
    , 424,
    fn. 5; see People v. Kemp (1961) 
    55 Cal. 2d 458
    , 476.) With respect to the joinder
    of count 4 to the other counts, the trial court noted that all four offenses occurred
    in the custodial context and involved a prison-made weapon. In addition, sections
    4500 (assault by a life prisoner) and 4502 (custodial possession of a weapon) serve
    an identical purpose — to prevent assaults by armed prisoners on prison staff and
    other inmates. (See People v. Custodio (1999) 
    73 Cal. App. 4th 807
    , 812 [“By
    23
    prohibiting prison inmates from possessing any instrument or weapon of the kind
    specified in the statute, section 4502, subdivision (a) is intended to protect inmates
    and correctional staff „from the peril of assaults with dangerous weapons
    perpetrated by armed prisoners‟ ”]; People v. Superior Court (Gaulden) (1977) 
    66 Cal. App. 3d 773
    , 778 [“Section 4500 was enacted for the purpose of promoting
    prison safety by discouraging assaults by prison inmates”].) Therefore, despite the
    fact that section 4502 does not require an intent to use the weapon (People v.
    Rodriguez (1975) 
    50 Cal. App. 3d 389
    , 395), that offense as charged shares
    common characteristics with the assaultive offenses charged in this case, and is,
    therefore, of the same class.
    Joinder was also proper because the offenses were “connected together in
    their commission.” (§ 954.) “[O]ffenses which are committed at different times
    and places against different victims are nevertheless „connected together in their
    commission‟ when they are, as here, linked by a „ “common element of substantial
    importance.” ‟ [Citations.]” (People v. Lucky (1988) 
    45 Cal. 3d 259
    , 276.) Here,
    the common thread among all four offenses is the use or possession by defendant
    of a prison-made stabbing weapon. Defendant contends the common element
    factor requires that the same weapon be involved in each crime. We rejected a
    similar argument in Alcala v. Superior Court (2008) 
    43 Cal. 4th 1205
    , in which the
    defendant claimed “only physical or objectively measurable factors, such as use of
    a specific individual weapon, can suffice” to establish the common element factor.
    (Id. at p. 1220.)
    Accordingly, we conclude that count 4 was properly joined with the other
    three offenses under section 954.
    In addition, because the evidence that defendant committed count 4 was
    strong and stood on its own without reference to the remaining counts, the
    evidence related to the other counts would not have improperly bolstered the
    24
    evidence pertaining to count 4. In light of the strength of the evidence related to
    each charge, “we cannot conclude that it is reasonably probable an outcome more
    favorable to defendant would have resulted” (People v. McLain (1988) 
    46 Cal. 3d 97
    , 106) if count 4 had not been joined with the other counts. For the same reason,
    any misjoinder did not result in such gross unfairness as to deprive defendant of
    his right to due process. (People v. Soper (2009) 
    45 Cal. 4th 759
    , 784 [“Appellate
    courts have found „ “no prejudicial effect from joinder when the evidence of each
    crime is simple and distinct, even though such evidence might not have been
    admissible in separate trials” ‟ ”].)
    As noted, defendant also contends the trial court abused its discretion by
    not severing counts 3 and 4 from counts 1 and 2. When charges are properly
    joined, a “ „ “defendant must make a clear showing of prejudice to establish that
    the trial court abused its discretion in denying defendant‟s severance motion.” ‟
    [Citation.] That is, defendant must demonstrate the denial of his motion exceeded
    the bounds of reason.” (People v. 
    Capistrano, supra
    , 59 Cal.4th at p. 848.)
    “ „Refusal to sever may be an abuse of discretion where (1) evidence of the crimes
    to be jointly tried would not be cross-admissible in separate trials; (2) certain of
    the charges are unusually likely to inflame the jury against the defendant; (3) a
    “weak” case has been joined with a “strong” case or with another “weak” case, so
    that the “spillover” effect of aggregate evidence on several charges might well
    alter the outcome of some or all of the charges; and (4) any one of the charges
    carries the death penalty or joinder of them turns the matter into a capital case.‟ ”
    (People v. Romero and Self (2015) 
    62 Cal. 4th 1
    , 30.) Even if a defendant fails to
    demonstrate the trial court‟s joinder ruling was an abuse of discretion when it was
    made, reversal may nonetheless be required if the defendant can demonstrate that
    “the joint trial resulted in such gross unfairness as to amount to a due process
    violation.” (Capistrano, at p. 853.)
    25
    Applying the four-part standard outlined above, defendant first contends
    evidence was not cross-admissible among the four counts. The trial court did not
    expressly refer to cross-admissibility in its ruling denying severance, but its
    comments focused on the similarities among the counts — within a two and one-
    half month period, while housed in the Palm Hall unit of the CIM, defendant
    committed offenses involving prison-made weapons. As defendant acknowledges,
    the trial court‟s ruling reflects the view that there was a common plan or scheme to
    commit assaults with prison-made weapons.
    To be admissible to prove a common plan or scheme, evidence of other
    misconduct “must demonstrate „not merely a similarity in the results, but such a
    concurrence of common features that the various acts are naturally to be explained
    as caused by a general plan of which they are the individual manifestations.‟ ”
    (People v. Ewoldt (1994) 
    7 Cal. 4th 380
    , 402.) The first three counts involved
    conduct to lull another inmate into a false sense of security followed by a surprise
    attack with a prison-made weapon. The fact that the attack on Addis occurred in
    the exercise yard in front of numerous witnesses and seemed to involve Green in
    the plan, whereas the attack on Matthews occurred while defendant was alone in
    his cell and with no participation by any other inmate, does not negate the
    significant similarities. (See Alcala v. Superior 
    Court, supra
    , 43 Cal.4th at
    p. 1225 [the similarity required to admit evidence to prove a common plan “can be
    met despite the existence of some factual differences between or among the
    charged offenses”].) Thus, the trial court did not abuse its discretion in implicitly
    finding the evidence in these three counts to be cross-admissible. Like the other
    three counts, count four involved the possession of a prison-made stabbing
    weapon. Therefore, the other counts were admissible to establish a common plan
    to possess a prison-made weapon such as the sharpened metal object that fell to
    the floor when the gate to defendant‟s cell was opened.
    26
    In addition, as defendant concedes, “even the complete absence of cross-
    admissibility does not, by itself, demonstrate prejudice from a failure to order a
    requested severance.” (Alcala v. Superior 
    Court, supra
    , 43 Cal.4th at p. 1221.)
    Rather, we look to the remaining three factors. (Ibid.) An examination of those
    factors does not reveal an abuse of discretion.
    First, none of the joined charges was unusually likely to inflame the jury
    against defendant. Defendant asserts the evidence of the attack on Matthews and
    the possession of a weapon would lead the jury to infer improperly that defendant
    “had a general disposition to violence,” and would “undercut his defense of duress
    and staff complicity and/or negligence in the Addis homicide based on the facts
    peculiar to that case.” The fact that evidence of two violent crimes might lead a
    jury to infer that a defendant is violent does not establish that any of the charges
    were unusually likely to inflame the jury. In addition, to the extent defendant‟s
    attack on Matthews and his possession of a weapon tended to show he repeatedly
    acted pursuant to a common plan rather than due to duress or negligence, or with
    the complicity of staff, such inferences were proper.4 Finally, as explained below,
    duress is not a defense to murder, nor does duress reduce murder to manslaughter.
    (See post, pp. 42-49.)
    4       Although it does not appear that the trial court was aware at the time it
    ruled on the severance motion of what defenses, if any, defendant would present to
    counts 3 and 4, we note, for purposes of evaluating whether the joint trial of these
    charges resulted in gross unfairness, that the defense presented evidence at trial
    that staff was complicit in the attack on Matthews. In particular, the defense
    elicited testimony from Matthews that he thought the officers allowed him to go to
    defendant‟s cell and “put [him] in a position for it to happen,” and it presented
    expert testimony concerning how the officers should have escorted Matthews so
    he could not get away from them. Also, as noted above, the defense ultimately
    conceded guilt with respect to counts 3 and 4.
    27
    Second, counts 1 and 2 were not supported by evidence that was so
    measurably stronger than the evidence supporting counts three and four that it
    would likely have had an improper spillover effect on counts 3 and 4. Defendant
    contends the evidence of the attack on Addis was stronger because there were
    eyewitnesses to it, but the circumstantial evidence that he attacked Matthews was
    just as strong. Defendant called him over, Matthews complied and turned his back
    to the porthole of defendant‟s cell door, and then Matthews staggered away from
    defendant‟s cell bleeding while guards heard defendant evidently flushing his
    weapon down the toilet. Similarly, the discovery of a prison-made weapon in a
    cell solely occupied by defendant constituted strong circumstantial evidence that
    he possessed that weapon.
    Third, “[t]he capital charges were not the result of joinder of the various
    incidents.” (People v. Mendoza (2000) 
    24 Cal. 4th 130
    , 162.) Contrary to
    defendant‟s arguments, we do not apply a heightened standard in assessing
    severance issues in capital cases. (People v. Trujeque (2015) 
    61 Cal. 4th 227
    , 260.)
    Defendant further contends that the trial court should have granted
    severance because denial of the motion assertedly prevented him from taking the
    stand. He claims he could have offered a defense to the Addis counts that was
    inapplicable to the remaining counts, but would then have also had to testify
    concerning the remaining counts.
    Defendant‟s theory of prejudice has been recognized by federal courts in
    interpreting their rule of procedure regarding severance, rule 14(a) of the Federal
    Rules of Criminal Procedure (18 U.S.C.). We noted in People v. Sandoval (1992)
    
    4 Cal. 4th 155
    , that we have not addressed this theory, and we concluded that the
    “[d]efendant‟s showing fell far short of anything that would have satisfied the
    federal standards or any standard this court might adopt.” (Id. at p. 174.) We have
    subsequently considered this theory without adopting it as part of our severance
    28
    analysis. (See People v. Johnson (2015) 
    61 Cal. 4th 734
    , 752; People v. Thomas
    (2012) 
    53 Cal. 4th 771
    , 800.) Although the federal courts‟ test is based on their
    interpretation of the federal rule and is not grounded in constitutional mandate, we
    will assume, without deciding, that the type of prejudice recognized by the federal
    courts could justify a trial court‟s decision to sever otherwise properly joined
    charges under California law.
    Although federal courts have interpreted their rule to permit severance
    when a defendant can show prejudice because he or she “ „wishes to testify to one
    charge but to remain silent on another‟ ” (U.S. v. Archer (7th Cir. 1988) 
    843 F.2d 1019
    , 1022), they recognize that “ „severance is not mandatory every time a
    defendant wishes to testify to one charge but to remain silent on another. If that
    were the law, a court would be divested of all control over the matter of severance
    and the choice would be entrusted to the defendant.‟ ” (Ibid.) Under the two-part
    test devised by the federal courts, “severance is required when a defendant
    demonstrates that he has both (1) important testimony to give concerning some
    counts and (2) a strong need to refrain from testifying with regard to other counts.”
    (U.S. v. Ely (7th Cir. 1990) 
    910 F.2d 455
    , 457, italics added.) To satisfy the
    second part of the test, the defendant must demonstrate that his or her testimony
    on the counts about which he or she did not wish to testify was essential to the
    prosecution‟s meeting its burden of proof on those charges. (Id. at p. 460; Archer,
    at p. 1022; U.S. v. Williamson (5th Cir. 1973) 
    482 F.2d 508
    , 513.)
    As noted, the trial court conducted an in camera hearing concerning
    defendant‟s desire to testify about the Addis attacks and how consolidation might
    affect his willingness to testify. At defendant‟s request, we have reviewed the
    sealed transcript of that hearing. The People have asked that the transcript be
    unsealed in the event it appears the trial court abused its discretion in denying
    severance. It is unnecessary to unseal the transcript, as defendant has failed to
    29
    satisfy the second part of the federal test. There was ample independent evidence
    of his attack on Matthews (count 3) and his possession of the prison-made weapon
    (count 4), quite apart from any testimony he may have offered or declined to offer
    regarding those counts. Accordingly, he fails to show he was prejudiced on this
    ground by the trial court‟s denial of his severance motion.
    Defendant makes several related arguments that can be quickly dispatched.
    First, he claims the trial court failed to instruct the jury to consider and decide each
    count separately, but as he concedes, the trial court did not have a duty to give the
    instruction without a request. (People v. Beagle (1972) 
    6 Cal. 3d 441
    , 456.)
    Second, he claims the prosecutor committed misconduct by arguing that the jury
    could indiscriminately use the evidence of all counts to prove each count. But
    defendant neither objected to the argument, thus forfeiting any claim of
    misconduct, nor did he request a limiting instruction. (People v. Lopez (2013) 
    56 Cal. 4th 1028
    , 1073; Evid. Code, § 355.) Third, he claims judicial economy would
    have been served by severing counts 1 and 2 from counts 3 and 4 because counts 3
    and 4 involved evidence that was not relevant to counts 1 and 2, and “there was
    every reason to believe that a verdict on the capital/murder charges would have led
    the parties to reach a disposition on other charges.” Evidence of the counts was
    cross-admissible, as explained above, and he cites no legal authority to support his
    novel and speculative theory regarding a disposition of the less serious charges.
    Finally, defendant contends denial of his severance motion resulted in such
    gross unfairness as to amount to a violation of his federal due process rights.
    (People v. 
    Capistrano, supra
    , 59 Cal.4th at p. 853.) Other than the asserted
    prejudice we have already discussed and rejected, defendant points to no
    additional unfairness assertedly resulting from the joint trial. We therefore
    conclude that defendant has failed to show a due process violation as the result of
    30
    the denial of his severance motion, or any violation of his rights to a fair trial, a
    trial by jury, and reliable capital case proceedings.
    C. Juror Questionnaire
    Defendant contends the trial court erroneously rejected two questions he
    asked to be included on the jury questionnaire pertaining to the prospective jurors‟
    attitudes about aspects of prison life. He contends the court‟s ruling violated his
    state and federal rights to due process, a fair trial, an impartial jury, and to a
    reliable determination of guilt and penalty in a capital case. (U.S. Const., 5th, 6th,
    8th & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a), 15, 16, & 17.)5 The claim
    is meritless.
    5       “With respect to this and virtually every other claim raised on appeal,
    defendant urges that the error or misconduct he is asserting infringed various of
    his constitutional rights to a fair and reliable trial. In most instances, insofar as
    defendant raised the issue at all in the trial court, he failed explicitly to make some
    or all of the constitutional arguments he now advances. In each instance, unless
    otherwise indicated, it appears that either (1) the appellate claim is of a kind (e.g.,
    failure to instruct sua sponte; erroneous instruction affecting defendant‟s
    substantial rights) that required no trial court action by the defendant to preserve it,
    or (2) the new arguments do not invoke facts or legal standards different from
    those the trial court itself was asked to apply, but merely assert that the trial
    court‟s act or omission, insofar as wrong for the reasons actually presented to that
    court, had the additional legal consequence of violating the Constitution. To that
    extent, defendant‟s new constitutional arguments are not forfeited on appeal.”
    (People v. Boyer (2006) 
    38 Cal. 4th 412
    , 441, fn. 17, applying People v. Partida
    (2005) 
    37 Cal. 4th 428
    , 433-439.) “In the latter case, no separate constitutional
    discussion is required or provided where rejection of a claim that the trial court
    erred on the issue presented to that court necessarily leads to rejection of any
    constitutional theory or „gloss‟ raised for the first time here.” (People v.
    Contreras (2013) 
    58 Cal. 4th 123
    , 139, fn. 17.) We apply this principle here and
    elsewhere where defendant asserts on appeal constitutional claims not advanced
    below.
    31
    1. Background
    Defendant proposed the following multipart question (question No. 40) to
    be included in the juror questionnaire:
    “What are your views on the prison system in the State of California?
    “A. To what extent can you consider evidence that living in the prison
    system, that is to say being a prisoner, is an ongoing experience entirely different
    from living in society as you know it?
    “B. Please indicate which statement best describes your opinion of life in
    the prison system prior to hearing evidence in this case:
    “____ Prisoners are safer on the inside that they would be on the outside
    “____ Prisoners are about as safe on the inside as they would be on the
    outside
    “____ Prisoners are less safe on the inside than they would be on the
    outside
    “C. Whatever your opinion as to the safety of living in the prison system
    may be, how willing are you to consider evidence that many prisoners‟ primary
    task on the inside is staying alive?”
    The prosecutor objected to subparts B and C, asserting they were
    argumentative and called upon the prospective jurors to prejudge the case. The
    prosecutor also asserted that the questions were vague as to what was meant by
    prisoner safety. The trial court declined to include subparts B and C. Regarding
    the latter, even defense counsel conceded it was a “little argumentative,” and
    proposed an alternative the trial court also declined to include. The court
    expressed its belief that the defense could ask follow up questions to subpart A “to
    get somewhat the same information, assuming it‟s an appropriately asked
    question.” At the defense‟s request, a space was provided after subpart A with the
    words “Please explain.” In its final form, subpart A (renumbered question No. 96,
    32
    subpart b on the questionnaire) read: “Would you be willing to consider evidence
    that living in the prison system, that is to say, being a prisoner, is an ongoing
    experience entirely different from living in society as you know it? Please
    explain.”
    2. Discussion
    Defendant contends the trial court‟s rejection of his questions regarding
    prisoner safety denied him the opportunity to “expose juror bias about prison
    inmate safety and survival, to lay the foundation for challenges for cause, and to
    explore prospective jurors[‟] views on issues related to the circumstances of the
    charged capital offense that would be important to the decision of whether or not
    to impose the death penalty.” As explained below, we find no abuse of discretion.
    Preliminarily, we dispose of the People‟s claim that defendant forfeited this
    issue because, after further discussion and further revision of the questionnaire,
    defense counsel agreed the questionnaire could be used. By then, however, the
    trial court had already rejected subparts B and C, and it would have been futile for
    defense counsel to renew the argument. Accordingly, we find no forfeiture and
    proceed to the merits.
    “There is no constitutional right to voir dire per se. Nor is there any
    constitutional right to conduct voir dire in a particular manner. [Citation.] Rather,
    the voir dire process serves as a means of implementing the defendant‟s Sixth
    Amendment right to an impartial jury. [Citations.] [¶] Consistent with applicable
    statutory law, the trial court has wide latitude to decide the questions to be asked
    on voir dire [citation], and to select the format in which such questioning occurs
    [citation]. The court likewise has broad discretion to contain voir dire within
    reasonable limits.” (People v. 
    Contreras, supra
    , 58 Cal.4th at p.143; fn. omitted;
    see Code Civ. Proc., § 223.) Thus, “ „ “content” questions,‟ even ones that might
    33
    be helpful, are not constitutionally required. [Citation.] To be an abuse of
    discretion, the trial court‟s failure to ask questions „must render the defendant‟s
    trial fundamentally unfair.‟ [Citation.] „Such discretion is abused “if the
    questioning is not reasonably sufficient to test the jury for bias or partiality.” ‟
    [Citation.]” (People v. Cleveland (2004) 
    32 Cal. 4th 704
    , 737; see also People v.
    Leon (2015) 
    61 Cal. 4th 569
    , 586.) It is not the purpose of voir dire to “ „educate
    the jury panel to the particular facts of the case, to compel the jurors to commit
    themselves to vote a particular way, to prejudice the jury for or against a particular
    party, to argue the case, to indoctrinate the jury, or to instruct the jury in matters of
    law.‟ ” (People v. Crowe (1973) 
    8 Cal. 3d 815
    , 824.)
    As defendant asserts, the issue of inmate safety and survival was “central to
    the defense to the capital/murder charges.” The principal purpose of the rejected
    questions appears to have been to begin educating the jurors about the defense.
    Moreover, as the prosecutor pointed out, the rejected questions were vague in that
    they did not specify what kind of threats to inmate safety and survival were at
    issue. This vagueness itself created an opening for defendant to fill in the blanks
    with, again, the objective of previewing the defense and inviting agreement with
    his view of inmate safety and survival. Finally, the trial court did not foreclose all
    questioning on this subject, but indicated it would allow the defense to pursue the
    subject should a prospective juror raise it in his or her answer to subpart A.
    Accordingly, we conclude that the trial court acted well within its discretion in
    rejecting the questions. We conclude further that the rejection of the proposed
    questions did not implicate the issue of death-qualification voir dire. (See
    Wainwright v. Witt (1985) 
    469 U.S. 412
    ; Witherspoon v. Illinois (1968) 
    391 U.S. 510
    ; People v. Butler (2009) 
    46 Cal. 4th 847
    , 859 [the purpose of Witherspoon-
    Witt voir dire is to determine only the views of prospective jurors about capital
    punishment].)
    34
    D. Admission of Defendant’s Letters
    Defendant contends the admission of jailhouse letters he wrote to another
    NLR gang member violated his federal and state constitutional rights to due
    process, a fair trial, a trial by jury, and to reliable capital proceedings. (U.S.
    Const. 5th, 6th, 8th & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a), 15, 16,
    17.) We disagree.
    1. Background
    Prison officials intercepted two letters defendant wrote to fellow NLR gang
    member, Joseph Lowery, who had once been defendant‟s cellmate. The officials
    photocopied the letters and then allowed them to be delivered to Lowery. The two
    letters were denominated People‟s exhibits Nos. 66 and 67. Exhibit No. 66
    consisted of a photocopied envelope and a letter dated September 9, 1997, sent
    from CIM, at Chino, where defendant was then housed. The envelope had
    defendant‟s name, prison number and address. Exhibit No. 67 was an undated
    photocopied letter that was faxed to David Lacey, the investigating officer in this
    case, at CIM from an Officer Harrison at Corcoran State Prison on December 22,
    1997, when defendant was housed at that institution. Glen Willett, the
    prosecution‟s prison gang expert, testified that prison authorities monitor prison
    gang members by intercepting their mail and reading it before passing it on.
    Lacey testified that outgoing letters by inmates are not allowed to be sealed. First,
    they are collected and read. If they contain information pertinent to an ongoing
    investigation, they are photocopied and the copies passed on to a supervisor.
    Finally, the original letters are delivered to their recipients. That was how Lacey
    obtained defendant‟s letters.
    Willett, the prison gang expert, testified concerning the contents of the
    letters for purposes of identifying defendant as either an associate or a member of
    the NLR. With respect to exhibit No. 66, he testified that Lowery was a known
    35
    NLR gang member and that defendant‟s use of the phrase “dawg o‟ mine,” was an
    endearment used among gang members. He testified further that the sentence,
    “Yeah, this 187 kinda put me at ease, had to earn it,” meant that defendant had “to
    work hard” to commit the “murder,” presumably the Addis homicide, and that
    committing the murder would elevate defendant‟s status with higher ranking NLR
    gang members like Lowery. With respect to exhibit No. 67, Willett testified
    defendant had signed it with his gang moniker “Smurf,” and had made reference to
    being relocated. He testified the phrase “so the KGB has been befuddled once
    again,” referred to prison authorities. He also noted defendant had again used the
    gang phrase “dawg o‟mine,” and well as the phrase “I hope this finds you in good
    health and strong mind,” which is a reference to racial purity. Defendant also
    referred to Gary Green‟s gang moniker, “Mop,” and to an Aryan Brotherhood
    gang member named Joseph Hayes who was then incarcerated at Pelican Bay.6
    Willett also testified that defendant‟s use of the word “homeplate,” was another
    gang endearment that was the “same as „homey.‟ ”
    Later in the trial, when the prosecutor moved for the admission of exhibit
    Nos. 66 and 67, the defense objected that there was no foundation that defendant
    wrote them. The prosecutor responded that the evidence showed Lowery and
    defendant were cellmates at one point, that defendant‟s prison number and address
    were written on the envelope in exhibit No. 66, and that “these are self-
    authenticating letters because of the content” and also because they were signed
    with defendant‟s gang moniker Smurf. Defense counsel argued there was no
    evidence regarding how prison officials obtained the letters. The prosecutor
    6     Willett testified that the NLR had begun as a feeder gang to the Aryan
    Brotherhood.
    36
    countered that Lacey‟s testimony regarding the interception and copying of inmate
    letters provided a proper foundation. She acknowledged, however, that it was not
    possible to establish who had originally collected the letters. The trial court
    admitted the letters.
    2. Discussion
    Defendant‟s argument regarding the admissibility of the letters is two-
    pronged. First, he contends the letters were inadmissible under the secondary
    evidence rule codified in Evidence Code section 1521. Second, he argues the
    letters were not properly authenticated under Evidence Code section 1401.
    Evidence Code section 1521 provides in part: “The content of a writing
    may be proved by otherwise admissible secondary evidence. The court shall
    exclude secondary evidence of the content of writing if the court determines either
    of the following: [¶] (1) A genuine dispute exists concerning material terms of
    the writing and justice requires the exclusion. [¶] (2) Admission of the secondary
    evidence would be unfair.” Enacted in 1998 — and thus applicable to defendant‟s
    2001 trial — the secondary evidence rule replaced the best evidence rule, which
    was repealed. “Under the secondary evidence rule, the content of a writing may
    now be proved either „by an otherwise admissible original‟ ([Evid. Code,] § 1520
    or by „otherwise admissible secondary evidence‟ ([Evid. Code,] § 1521, subd. (a);
    [citation]).” (People v. Goldsmith (2014) 
    59 Cal. 4th 258
    , 269.)
    Here, as noted, photocopies of the letters and the one envelope were
    admitted rather than the originals because, as Lacey explained, once the
    photocopies were made, the originals were delivered to their intended recipient.
    Defendant now asserts the admission of the copies was error. At no time did
    defendant object to admission of the documents under the secondary evidence
    rule. Rather, his objection went to their authenticity.
    37
    “ „As a general rule, “the failure to object to errors committed at trial
    relieves the reviewing court of the obligation to consider those errors on appeal.”
    [Citation.] . . .‟ This rule applies equally to any claim on appeal that the evidence
    was erroneously admitted, other than the stated rule for the objection at trial.”
    (People v. Kennedy (2005) 
    36 Cal. 4th 595
    , 612; accord, Evid. Code, § 353.) This
    principle applies with particular force here, because before the trial court can
    exclude otherwise admissible secondary evidence, Evidence Code section 1521
    requires the court to make specific factual determinations. These include whether
    a genuine dispute exists concerning material terms of the writing, and whether
    admission of the evidence would be unfair. The trial court cannot make such
    findings if a party fails to make a proper, specific, and timely objection, nor can
    we review the basis of the trial court‟s determination where no findings were made
    due to defendant‟s failure to have lodged the appropriate objection. Therefore,
    contrary to defendant‟s view, his various objections to Willett‟s interpretation of
    certain phrases in the letters did not amount to a proper objection under the
    secondary evidence rule. Accordingly, the claim is forfeited.
    As noted above, defendant also contends the letters were not properly
    authenticated. A writing that qualifies for admission under the secondary evidence
    rule must, nonetheless, be authenticated before it can be admitted. “The
    Secondary Evidence Rule does not „excuse[] compliance with [Evidence Code]
    Section 1401 (authentication).‟ ([Evid. Code] § 1521, subd.(c).) Thus, to be
    „otherwise admissible,‟ secondary evidence must be authenticated.” (People v.
    Skiles (2011) 
    51 Cal. 4th 1178
    , 1187, fn. omitted; see Evid. Code § 1401, subd. (b)
    [“Authentication of a writing is required before secondary evidence of its content
    may be received in evidence”].)
    “Authentication is to be determined by the trial court as a preliminary fact
    ([Evid. Code,] § 403, subd. (a)(3)) and is statutorily defined as „the introduction of
    38
    evidence sufficient to sustain a finding that it is the writing that the proponent of
    the evidence claims it is‟ or „the establishment of such facts by any other means
    provided by law‟ ([Evid. Code,] § 1400).” (People v. 
    Goldsmith, supra
    , 59
    Cal.4th at p. 266.) “The means of authenticating a writing are not limited to those
    specified in the Evidence Code. ([Evid. Code,] § 1410 [„[n]othing in this article
    shall be construed to limit the means by which a writing may be authenticated or
    proved‟]; [citation].) For example, a writing can be authenticated by
    circumstantial evidence and by its contents.” (People v. 
    Skiles, supra
    , 51 Cal.4th
    at p. 1187.)
    The testimony of Glen Willett and Officer Lacey was sufficient to sustain
    the trial court‟s finding of authenticity. Both men testified to the general protocol
    by which inmate letters are monitored and, when appropriate, copied and turned
    over to prison authorities as possible evidence in ongoing investigations.
    Defendant‟s letters were of obvious interest to Lacey, who was investigating
    defendant‟s attack on Addis. The envelope that was part of exhibit No. 66 showed
    as its return address defendant‟s address, along with his inmate number, and was
    sent while he was at CIM. Similarly, exhibit No. 67, the letter faxed to Lacey in
    December 1997 from Corcoran State Prison, was written while defendant was
    housed at that institution and refers to his having been relocated; he had in fact
    been transferred from CIM to Corcoran. The contents of the letter, about which
    Willett testified, lends further support for its authenticity. The reference to a
    “187,” that is, a murder, and the context in which the reference is made, are
    inferentially references to the attack on Addis by defendant, for which he is
    claiming credit. Other references in the letters, to mutual acquaintances like Gary
    Green and Joseph Hayes, and defendant‟s familiar tone with the recipient, Lowery,
    his one-time cellmate, as well as his use of his own gang moniker, Smurf, also
    provide circumstantial support that he authored the letters. (See Evid. Code,
    39
    § 1421: “A writing may be authenticated by evidence that the writing refers to or
    states matters that are unlikely to be known to anyone other than the person who is
    claimed by the proponent of the evidence to be the author of the writing.”)
    Defendant argues that all of this information was known to individuals
    other than himself, making it possible that the letters were forged. However,
    “ „[a]s long as the evidence would support a finding of authenticity, the writing is
    admissible. The fact conflicting inferences can be drawn regarding authenticity
    goes to the document‟s weight as evidence, not its admissibility.‟ [Citation.]”
    (People v. 
    Goldsmith, supra
    , 59 Cal.4th at p. 267.)
    Accordingly, we conclude the trial court did not abuse its discretion in
    admitting exhibit Nos. 66 and 67 into evidence.
    E. Excusal of Sick Juror
    On the day set for closing arguments and instruction, the court, over
    defendant‟s objection, excused a sick juror and seated an alternate. Defendant
    contends the trial court‟s decision to replace the sick juror was an abuse of
    discretion and also violated his federal and state constitutional rights to a fair and
    impartial jury trial and a reliable penalty determination. (U.S. Const., 5th, 6th, 8th
    & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a), 15, 16, 17.) The claim is
    meritless.
    1. Background
    On the morning of April 18, 2001, the day set for closing arguments and
    instructions, the trial court informed counsel that Juror No. 10 had called in sick
    with the flu. The court indicated it was inclined to replace the juror because the
    “flu that‟s going around does not seem to be something that will get well [sic] in a
    day or two.” Defense counsel requested and was granted a recess to review his
    jury list and consult with defendant. When the proceedings resumed, defense
    40
    counsel objected to replacing the sick juror and asked the court to wait for a day to
    see whether the juror had recovered. The prosecutor suggested the court speak to
    the juror directly. With consent of both counsel, the trial court telephoned the
    juror and put her on speakerphone. The juror reported she had been vomiting all
    night and did not anticipate recovering that week. The judge asked if she would
    be available on Monday, to which she said yes, although she acknowledged she
    had not been to the doctor.
    After speaking to the juror, the court noted that a delay from Wednesday to
    Monday would result in the loss of three court days. Defense counsel stated “it‟s
    reasonable to wait for that person until Monday.” The trial court, however,
    excused Juror No. 10 and replaced her with an alternate.
    2. Discussion
    Section 1089 states in pertinent part that “[i]f at any time, whether before or
    after the final submission of the case to the jury, a juror . . . becomes ill . . . , the
    court may order the juror to be discharged” and replaced by an alternate juror.
    “We review such a decision for abuse of discretion.” (People v. Smith (2005) 
    35 Cal. 4th 334
    , 348-349.) “The court‟s discretion is not unbounded: it must
    determine whether good cause exists to discharge the juror, and its reasons for
    discharge must appear in the record as a demonstrable reality.” (People v. Roberts
    (1992) 
    2 Cal. 4th 271
    , 325.) The trial judge is not required, however, to “elicit
    conclusive proof of the length of future incapacitation; judges are lawyers, not
    doctors.” (People v. Duff (2014) 
    58 Cal. 4th 527
    , 560, fn. omitted.) Nor must the
    incapacitation exceed a specific length of time. “[I]n the right circumstances, an
    absence of a day or less may warrant excusal. [Citations.] Whether a juror‟s
    illness can best be accommodated by a continuance or replacement with an
    alternate is a matter committed to the trial court‟s discretion.” (Id. at pp. 560-561.)
    41
    Here, there is no dispute the juror was ill. Although she believed she might
    be well the following Monday, five days and three court days later, this was
    merely an estimate on her part. Meanwhile, as defendant acknowledges, the trial
    had gone on for almost two months and was set to enter its final phase of closing
    argument and instruction on the day the juror called in sick. Whether, as he
    insists, a three-day continuance would have been reasonable is not the question we
    must answer. The question is whether, under these circumstances, the trial court‟s
    decision to proceed with an alternate juror was an abuse of discretion. In light of
    the uncertainty of the juror‟s prognosis and the crucial point at which the trial had
    arrived, we conclude the trial court did not abuse its discretion.
    F. Claims of Instructional Error
    1. Instructions Regarding Duress
    Defendant contends the trial court‟s denial of four proposed defense
    instructions concerning duress violated his federal constitutional rights to due
    process, effective assistance of counsel and a reliable penalty determination. (U.S.
    Const., 5th, 6th, 8th and 14th Amends.) The claim is meritless.
    The defense of duress is set forth in section 26, which states in relevant
    part: “All persons are capable of committing crimes except those belonging to the
    following classes: [¶] . . . [¶] Six — Persons (unless the crime be punishable
    with death) who committed the act or made the omission charged under threats or
    menaces sufficient to show that they had reasonable cause to and did believe their
    lives would be endangered if they refused.” As noted above, defendant argued
    that his attack on Addis, the basis of counts 1 and 2, was committed under duress
    because the attack was ordered by the NLR and, had defendant failed to carry it
    out, he himself would have been killed.

    To establish the defense, defendant requested four duress instructions, two
    pertaining to the first degree murder charge (count 1) and two to the charge of
    assault by a life prisoner with malice aforethought (count 2.)7 The trial court
    7       The four requested instructions were as follows:
    1. “In this case, you may consider evidence showing the existence of threats,
    menaces or compulsion that played a part in inducing the unlawful killing of a human
    being for such bearing as it may have on the question of whether the murder alleged
    in Count 1 was of the first or second degree. If you find from the evidence that at the
    time the alleged crime was committed the defendant honestly and reasonably held a
    belief that his own life was in danger, you must consider what effect, if any, this
    belief had on the defendant and whether he formed any of the specific mental states
    that are essential elements of murder. [¶] Thus if you find he had an honestly and
    reasonably held belief that his life was in peril and as a result did not maturely and
    meaningfully premeditate, deliberate and reflect on the gravity of his contemplated
    act or form an intent to kill, you cannot find him guilty of a willful, deliberate and
    premeditated murder of the first degree.” [¶] Also, if you find the defendant did not
    form the mental state constituting express malice, you cannot find him guilty of
    murder of either the first or second degree. You may however, find him guilty of the
    crime of voluntary manslaughter as defined in these instructions.”
    2. “The distinction between murder and manslaughter is that murder requires
    malice while manslaughter does not. [¶] When the act causing death, though
    unlawful, is done under the actual and reasonable belief in the necessity to act
    because of imminent peril to life or great bodily injury, the offense is manslaughter.
    In that case, even if an intent to kill exists, the law is that malice, which is an essential
    element of murder, is absent. [¶] To establish that a killing is murder and not
    manslaughter, the burden is on the People to prove beyond a reasonable doubt each of
    the elements of murder and that the act which caused death was not done under the
    actual and reasonable belief in the necessity to act because of imminent peril to life or
    great bodily injury.”
    3. “With respect to Count 2, the crime of Assault By A Life Prisoner With
    Malice Aforethought is not committed unless the element of malice aforethought is
    proved. [¶] If you find that the defendant acted under the actual and reasonable
    belief in the necessity to act because of imminent peril to life or great bodily injury,
    there is no malice aforethought and the crime alleged in Count 2 is not committed.
    [¶] As to this alleged offense, the burden is on the People to prove beyond a
    reasonable doubt each of the elements of the offense and that the act which caused
    death was not done under the actual and reasonable belief in the necessity to act
    because of imminent peril to life or great bodily injury.”
    4. “In this case, you may consider evidence showing the existence of
    threats, menaces or compulsion that played a part in inducing the unlawful assault
    (footnote continued on next page)
    43
    rejected the instructions on the ground that there was insufficient evidence that
    defendant personally entertained a good faith belief that his action — attacking
    Addis — was necessary because his own life was in danger.
    Nonetheless, in response to the prosecutor‟s request that the court “say
    something about” duress, the court gave a modified version of CALJIC No. 4.40
    (Threats and Menaces) as follows: “A person is not guilty of a crime other than
    Assault by a Life Prisoner as alleged in Count 2 when he engages in conduct,
    otherwise criminal, when acting under threat and menace under the following
    circumstances: [¶] 1. Where the threat and menace are such that they would cause
    a reasonable person to fear that his life would be in immediate danger if he did not
    engage in the conduct charged, and [¶] 2. If this person then believed that his life
    was so endangered. [¶] This rule does not apply to threats, menaces, and fear of
    (footnote continued from previous page)
    upon inmate Addis resulting in death of the inmate as alleged in Count 2, for such
    bearing as it may have on the question of whether that crime was committed. If
    you find from the evidence that at the time the alleged crime was committed the
    defendant honestly and reasonably held a belief that his own life was in danger,
    you must consider what effect, if any, this belief had on the defendant and whether
    he formed any of the specific mental states that are essential elements of this
    particular crime. Thus if you find he had an honestly and reasonably held belief
    that his life was in peril and as a result did not form the mental state constituting
    malice aforethought, which is an element of the crime, you may not find him
    guilty of said crime. [¶] You may however, find him guilty of the crime of any
    lesser included offenses such as assault with a deadly weapon as defined in these
    instructions.”
    Defendant acknowledges the proposed instructions are erroneous in two
    respects: first, the requirement that a defendant maturely and meaningfully reflect
    upon his or her act had been eliminated from section 189 prior to defendant‟s trial
    and, second, the instruction erroneously stated express malice was required for
    murder when section 189 states that such malice may be either express or implied.
    44
    future danger to his life, nor does it apply to the crime of Assault By a Life
    Prisoner as alleged in Count 2.”8
    We need not decide whether the trial court was correct that there was
    insufficient evidence to support the requested instructions, because we have since
    held that duress is not a defense to murder, nor does duress reduce murder to
    manslaughter. (People v. Anderson (2002) 
    28 Cal. 4th 767
    , 772-785 (Anderson);
    see People v. Burney (2009) 
    47 Cal. 4th 203
    , 249-250; People v. Hinton (2006) 
    37 Cal. 4th 839
    , 882-883; People v. Wilson (2005) 
    36 Cal. 4th 309
    , 331-332; People v.
    Maury (2003) 
    30 Cal. 4th 342
    , 421-422.)
    In 
    Anderson, supra
    , 
    28 Cal. 4th 767
    , the defendant urged the court to
    construe section 26 to exempt only capital crimes from the defense of duress. In
    response, we noted that at common law, duress was not a defense to killing an
    innocent person. (Id. at p. 772.) We further observed that when California
    recognized the defense in 1850, all murder was punishable by death. We
    concluded that as enacted, “section 26 effectively adopted the common law”
    (
    Anderson, supra
    , at p. 774), thereby barring duress as a defense to murder. In the
    course of our discussion, we observed that “[i]f duress is recognized as a defense
    to the killing of innocents, then a street or prison gang need only create an internal
    8       The instruction‟s exclusion of the crime of assault by a life prisoner reflects
    section 26‟s exclusion of “crime[s] punishable by death” from the defense of
    duress. (See § 4500.) In the trial court, defense counsel acknowledged that his
    proposed instructions on the effect of duress on count 2, which charged assault by
    a life prisoner in violation of section 4500, was foreclosed by the explicit language
    of section 26. For this reason, we reject defendant‟s claim that the trial court erred
    in failing to instruct that duress could serve as a basis for the jury to reduce count
    2 to assault with a deadly weapon. For this purpose, we assume, without deciding,
    that defense counsel‟s acknowledgement that section 26 did not apply to count 2,
    and his agreement to the modified duress instruction given, which specifically
    excluded count 2, did not forfeit the claim.
    45
    reign of terror and murder can be justified, at least by the actual killer.” (Id. at
    p. 777, italics added.)
    We also rejected the defendant‟s theory that even if duress is not a complete
    defense to murder, “at least it reduces the crime to manslaughter by negating
    malice.” (
    Anderson, supra
    , 28 Cal.4th at p. 781.) We noted that for purposes of
    voluntary manslaughter — an unlawful killing without malice — the absence of
    malice is limited to two circumstances: “ „ “when the defendant acts in a „sudden
    quarrel or heat of passion‟ (§ 192, subd. (a)), or when the defendant kills in
    „unreasonable self-defense‟ — the unreasonable but good faith belief in having to
    act in self-defense [citations].” ‟ ” (Ibid.) We observed that “[n]either of these
    two circumstances describes the killing of an innocent person under duress.”
    (Ibid.) We declined to carve out a third circumstance negating malice, based on
    duress. Unlike a person who has an unreasonable belief it is necessary to kill in
    self-defense, and therefore intends to kill lawfully, “a person who kills an innocent
    believing it necessary to save the killer‟s own life intends to kill unlawfully, not
    lawfully.” (Id. at p. 783.) We recognized that policy arguments could be made to
    recognize duress as a factor reducing culpability, but observed that “because
    duress can often arise in a criminal gang context, the Legislature might be
    reluctant to do anything to reduce the current law‟s deterrent effect on gang
    violence. These policy questions are for the Legislature, not a court, to decide.”
    (Id. at p. 784.) Defendant sets forth no argument that persuades us to reconsider
    these conclusions.
    Defendant seeks to avoid Anderson‟s holding on the basis that Anderson
    did not consider whether duress may be a defense to murder as a matter of federal
    constitutional law. He maintains that evolving standards of decency and
    heightened requirements of a reliable death penalty pursuant to the Eighth
    Amendment require recognition of duress as a defense to murder. Defendant does
    46
    not cite any case that has so held, and we are not persuaded that his citation to
    legal commenters represents a national consensus that has developed against the
    rule we announced in Anderson. (Cf. Atkins v. Virginia (2002) 
    536 U.S. 304
    , 313-
    317 [tracing legislative actions prohibiting the execution of intellectually disabled
    persons as evidence of a national consensus against that practice].)
    Defendant also asserts that his federal constitutional rights to due process
    and to present a defense required the trial court to give his proposed instructions
    and allow the jury to consider whether his claim of duress created a reasonable
    doubt regarding malice. The high court has acknowledged, however, that “dealing
    with crime is much more the business of the States than it is of the Federal
    government, [citation], and [it] should not lightly construe the Constitution so as to
    intrude upon the administration of justice by the individual States. (Patterson v.
    New York (1977) 
    432 U.S. 197
    , 201 [New York statute allocating burden on
    defendant to prove affirmative defense of extreme emotional disturbance does not
    violate the due process clause].) “When a State‟s power to define criminal
    conduct is challenged under the Due Process Clause, we inquire only whether the
    law „offends some principle of justice so rooted in the traditions and conscience of
    our people as to be ranked as fundamental.‟ [Citation.]” (Montana v. Egelhoff
    (1996) 
    518 U.S. 37
    , 58 (conc. opn. of Ginsberg, J.) [Montana statute eliminating
    voluntary intoxication as a defense does not violate due process].)
    Consistent with these principles, the United States Court of Appeals for the
    Fifth Circuit rejected a claim that Louisiana‟s statute excluding duress as a defense
    to murder violated the defendant‟s federal due process rights.9 “The state
    9      The Louisiana statute permits a justification defense “[w]hen any crime,
    except murder, is committed through the compulsion of threats by another of death
    or great bodily harm, and the offender reasonably believes the person making the
    (footnote continued on next page)
    47
    legislatures have vast powers to establish the elements of crimes, subject to the
    substantive provisions of the Constitution. [Citations.] Where a fundamental right
    is involved, the state‟s legislative authority must yield. [Citation.] Obviously,
    there is no fundamental right to commit murder, even under duress. Substantive
    due process is not implicated.” (Glass v. Blackburn (5th Cir. 1986) 
    791 F.2d 1165
    , 1171.)
    As we noted in Anderson, section 26 represents a legislative decision to
    adopt the common rule excluding duress as a defense to murder. (
    Anderson, supra
    , 28 Cal.4th at p. 774.) California‟s position is consistent with the majority
    of states that have considered the issue and adopted the common law rule. (U.S. v.
    LaFleur (9th Cir. 1992) 
    971 F.2d 200
    , 205, and statutes and cases cited therein.)
    The Legislature‟s adoption of the venerable common rule excluding duress as a
    defense to murder does not implicate a fundamental right. Accordingly, we reject
    defendant‟s claim that federal constitutional law required the trial court to give the
    requested instructions.
    Finally, defendant contends the trial court should have instructed the jury
    that evidence of duress could negate premeditation and deliberation, thereby
    resulting in second degree murder. (See 
    Anderson, supra
    , 28 Cal.4th at p. 784
    [“We agree that a killing under duress, like any killing, may or may not be
    premeditated, depending on the circumstances”].) In Anderson, we concluded this
    concept was sufficiently addressed by language in CALJIC No. 8.20 (Deliberate
    and Premeditated Murder) instructing the jury that “a killing „upon a sudden heat
    (footnote continued from previous page)
    threats is present and would immediately carry out the threats if the crime were not
    committed . . . .” (La. Rev. Stat. § 14:18(6) available from La. State Legis. Online
    at https://legis.la.gov/Legis/Law.aspx?d=78335 [as of December 12, 2016].)
    48
    of passion or other condition precluding the idea of deliberation‟ would not be
    premeditated first degree murder.” (
    Anderson, supra
    , at p. 784.) Not only was
    CALJIC No. 8.20 given in this case, but, as noted, defendant received the
    unwarranted benefit of a modified duress instruction. We reject defendant‟s
    contention that these instructions were inadequate on this point.
    2. CALJIC No. 8.20
    Defendant contends that the use of the word “precluding” in CALJIC
    No. 8.20 (Deliberate and Premeditated Murder) in referring to circumstances that
    would negate the element of deliberation effectively lowered the prosecution‟s
    burden of proof and violated his federal and state constitutional rights to due
    process, trial by jury and a reliable penalty determination. (U.S. Const., 5th, 6th,
    8th & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a), 15, 16, 17.)
    As given in this case, CALJIC No. 8.20 provided:
    “All murder which is perpetrated by any kind of willful, deliberate and
    premeditated killing with express malice aforethought is murder of the first
    degree. The word „willful,‟ as used in this instruction, means intentional. [¶] The
    word „deliberate‟ means formed or arrived at or determined upon as a result of
    careful thought and weighing of considerations for and against the proposed
    course of action. The word „premeditated‟ means considered beforehand. [¶] If
    you find that the killing was preceded and accompanied by a clear, deliberate
    intent on the part of the defendant to kill, which was the result of deliberation and
    premeditation, so that it must have been formed upon pre-existing reflection and
    not under a sudden heat of passion or other condition precluding the idea of
    deliberation, it is murder of the first degree.” (Italics added.)
    Defendant contends that, in context, the instruction required the jury to find
    evidence that would have entirely prevented deliberation before the jury could find
    49
    the crime to be less than first degree murder, a more onerous standard than
    requiring merely that the evidence raise a reasonable doubt. He asserts: “The jury
    should have been instructed that, if it found evidence of a sudden heat of passion
    or other condition sufficient to giv[e] rise to a reasonable doubt of deliberation, it
    must give the defendant the benefit of the doubt and find him not guilty of first
    degree murder.” He relies on various legislative, dictionary and judicial usages of
    the word “precluding” to support his view that the jury would have understood the
    word to mean “prevent entirely.”
    The People respond that the claim is forfeited by defendant‟s failure to seek
    modification of the instruction or by his attorney‟s agreement to the instruction.
    Assuming defendant‟s argument challenges the correctness of the instruction and
    therefore is not forfeited (see § 1259), it is nonetheless meritless.10
    As defendant acknowledges, we have previously considered and rejected an
    identical challenge to CALJIC No. 8.20. In People v. Nakahara (2003) 
    30 Cal. 4th 705
    (Nakahara), the defendant contended that the word “precluding” in CALJIC
    No. 8.20 was “too strong and could be interpreted as requiring him to absolutely
    preclude the possibility of deliberation, as opposed to merely raising a reasonable
    doubt on that issue.” (Nakahara at p. 715.) We concluded that “this instruction is
    unobjectionable when, as here, it is accompanied by the usual instructions on
    reasonable doubt, the presumption of innocence, and the People‟s burden of proof.
    These instructions make it clear that a defendant is not required to absolutely
    preclude the element of deliberation.” (Ibid.; accord, People v. Pearson (2012) 
    53 Cal. 4th 306
    , 326; People v. Morgan (2007) 
    42 Cal. 4th 593
    , 620-621.)
    10     Pursuant to section 1259, an appellate court may “review any instruction
    given, refused or modified, even though no objection was made thereto in the
    lower court, if the substantial rights of the defendant were affected thereby.”
    50
    Defendant asserts that Nakahara should not control because it did not
    consider the various usages of “precluding” that he presents here and that he has
    drawn from sources other than jury instructions. In considering a claim of
    instructional error, however, we do not look far and wide for all possible usages of
    a word the defendant has singled out as error nor do we focus solely on that single
    word. Rather, “[t]he relevant inquiry here is whether, „in the context of the
    instructions as a whole and the trial record, there is a reasonable likelihood that the
    jury was misled to defendant‟s prejudice.‟ [Citation.] Also, „ “ „we must assume
    that jurors are intelligent persons and capable of understanding and correlating all
    jury instructions which are given.‟ [Citation].” ‟ ” (People v. Sattiewhite (2014)
    
    59 Cal. 4th 446
    , 475.) This was the standard we applied in Nakahara as is evident
    by our references to the others instructions pertinent to CALJIC 8.20. We apply
    the same standard here and again reject this challenge to CALJIC No. 8.20.
    3. Implied Malice Second Degree Murder Instruction
    Defendant contends the trial court erred by failing to instruct the jury, on its
    own motion, concerning the lesser included offense of implied malice second
    degree murder.11 He asserts the error violated his rights to due process and a trial
    by jury, and the proscription against cruel and unusual punishment. (U.S. Const.,
    5th, 6th, 8th & 14th Amends.) We find no error.
    11      Defendant contends the trial court should have instructed the jury with
    CALJIC No. 8.31 (Second Degree Murder — Killing Resulting From Unlawful
    Act Dangerous To Life), as follows:
    “Murder of the second degree is also the unlawful killing of a human being
    when: [¶] 1. The killing resulted from an intentional act, [¶] 2. The natural
    consequences of the act are dangerous to human life, and [¶] 3. The act was
    deliberately performed with knowledge of the danger to, and with conscious
    disregard for, human life. [¶] When the killing is the direct result of such an act,
    it is not necessary to prove that the defendant intended that the act would result in
    the death of a human being.” (CALJIC No. 8.31.)
    51
    “A trial court has a sua sponte duty to „instruct on a lesser offense
    necessarily included in the charged offense if there is substantial evidence the
    defendant is guilty only of the lesser.‟ [Citation.] Substantial evidence in this
    context is evidence from which a reasonable jury could conclude that the
    defendant committed the lesser, but not the greater, offense. „The rule‟s purpose
    is . . . to assure, in the interest of justice, the most accurate possible verdict
    encompassed by the charge and supported by the evidence.‟ [Citation.] In light of
    this purpose, the court need instruct the jury on a lesser included offense only
    „[w]hen there is substantial evidence that an element of the charged offense is
    missing, but that the accused is guilty of‟ the lesser offense.” (People v. Shockley
    (2013) 
    58 Cal. 4th 400
    , 403-404, italics added.)
    A finding of express malice requires evidence of an intent to kill, whereas a
    finding of implied malice requires only an “intent to do an act dangerous to human
    life with conscious disregard of its danger.” (People v. Breverman (1998) 
    19 Cal. 4th 142
    , 188.) Here, there is no substantial evidence that defendant intended
    only to commit an action that was dangerous to human life, and did not intend to
    kill. The evidence reflects that Gary Green ordered a hit on Addis, and defendant
    contended at trial that if he had not carried out the hit, he would have been killed.
    After Green demanded that Addis be let into the yard, Green and defendant
    walked around together in the yard and ignored Addis. Thereafter, defendant told
    Addis, “It‟s all right, Danny. Go ahead and play cards.” Ten or 15 minutes later,
    Green and defendant walked together to the card table, and defendant stood to the
    left of Addis. One or two minutes after that, defendant, with one strong blow to
    Addis‟s neck, severed his jugular and subclavian veins. In a letter to another gang
    member, defendant stated that he had to work to earn this murder, and that
    committing the murder would elevate his status with higher ranking NLR gang
    52
    members. These facts reflect an intent to kill, and cannot be construed to reflect
    only an intent to commit a dangerous act with conscious disregard of its danger.
    Defendant directs us to cases in which courts found sufficient evidence of
    implied malice based on an assault with a knife. (see, e.g., People v. Pacheco
    (1981) 
    116 Cal. App. 3d 617
    , 627.) He also points to evidence that he and Addis
    were “having words” just before defendant stabbed him, and that Addis had
    previously threatened harm to defendant. Although it is true that an assault with a
    knife may reflect implied malice, the issue here is whether there is substantial
    evidence that defendant acted with only a conscious disregard for human life. He
    does not explain how the evidence he cites — his use of a knife, “words” before
    the assault, and a threat on some prior occasion — constituted substantial evidence
    that he acted only with conscious disregard for human life. On the contrary, all of
    the relevant evidence reflects an intent to kill.
    4. Voluntary Manslaughter Instruction
    As previously noted, defendant requested voluntary manslaughter
    instructions on a duress theory that the trial court rejected. On appeal, he contends
    the trial court had a duty to instruct the jury, on its own motion, regarding three
    other theories of voluntary manslaughter: sudden quarrel or heat of passion;
    imperfect self-defense; and assault with a deadly weapon without malice
    aforethought. He claims the trial court‟s failure to do so violated his state and
    constitutional rights to due process, trial by jury, a fair trial, and a reliable penalty
    determination. (U.S. Const., 5th, 6th, 8th & 14th Amends.; Cal. Const. art. I, §§ 7,
    subd. (a), 15, 16.) The claim is meritless.
    As noted above in our discussion of defendant‟s claim of instructional error
    regarding duress (ante, pp. 42-49), the element of malice may be negated by
    evidence that (1) the defendant acted in a sudden quarrel or heat of passion, or (2)
    53
    the defendant unreasonably but in good faith believed it was necessary to act in
    self-defense. If either of these circumstances is found, an unlawful killing will be
    voluntary manslaughter rather than murder. “Only these circumstances negate
    malice when a defendant intends to kill.” (People v. Manriquez (2005) 
    37 Cal. 4th 547
    , 583.)
    The heat of passion sufficient to reduce murder to manslaughter “exists
    only where „the killer‟s reason was actually obscured as a result of a strong
    passion aroused by a “provocation” sufficient to cause an “ „ordinary [person] of
    average disposition . . . to act rashly or without due deliberation and reflection, and
    from this passion rather than from judgment.‟ ” ‟ ” (People v. Carasi (2008) 
    44 Cal. 4th 1263
    , 1306.) The belief required to support imperfect self-defense is that
    the defendant “was in imminent danger of death or great bodily injury.” (People
    v. Booker (2011) 
    51 Cal. 4th 141
    , 182.) This doctrine is a “ „narrow‟ ” one and
    “will apply only when the defendant has an actual belief in the need for self-
    defense and only when the defendant fears immediate harm that „ “ „must be
    instantly dealt with.‟ ” ‟ ” (People v. Rogers (2006) 
    39 Cal. 4th 826
    , 883.)
    A trial court must instruct a jury regarding lesser included offenses
    “ „ “whenever evidence that the defendant is guilty only of the lesser offense is
    „substantial enough to merit consideration‟ by the jury [Citations.] „Substantial
    evidence‟ in this context is „ “evidence from which a jury composed of reasonable
    [persons] could . . . conclude[]” ‟ that the lesser offense, but not the greater was
    committed.” ‟ ” (People v. 
    Sattiewhite, supra
    , 59 Cal.4th at p. 477.)
    Defendant identifies the same evidence to support each of these two
    theories of voluntary manslaughter. First, Richard Allen, a former inmate,
    testified that he heard defendant and Addis “having words” just before the fatal
    attack. Second, one of defendant‟s letters to Joseph Lowery included a statement
    that the victim had decided to “disrespect me, and threaten harm to me” and “to
    54
    kill me on the yard.” Undermining this evidence, however, is the fact that Allen
    also testified that the victim, who was seated at a table playing cards when
    defendant approached him from behind, did not threaten defendant. Furthermore,
    Allen‟s belief that the two were arguing was based solely on the tone of
    defendant‟s voice, which “sounded angry.” Finally, Allen did not hear what the
    two men were saying to each other. Regarding the letter, defendant did not
    identify when the alleged threat occurred. This evidence, even if credited, does
    not begin to demonstrate either provocation for purposes of heat of passion
    voluntary manslaughter or imminence of danger of death for purposes of imperfect
    self-defense voluntary manslaughter. Accordingly, the trial court was not required
    to instruct on either theory.
    Last, defendant cites People v. Garcia (2008) 
    162 Cal. App. 4th 18
    , in
    support of his contention that the trial court should have instructed the jury
    concerning voluntary manslaughter because there was evidence he committed an
    assault with a deadly weapon without malice aforethought. His reliance on Garcia
    is in vain, that decision having been disapproved by this court in People v. Bryant
    (2013) 
    56 Cal. 4th 959
    , 970, on the very point for which he cites it. In Bryant, we
    held that a killing without malice in the commission of an inherently dangerous
    assaultive felony “cannot be voluntary manslaughter because voluntary
    manslaughter requires either an intent to kill or a conscious disregard for life.”
    (Ibid.) Accordingly, this argument is foreclosed by Bryant.
    5. Expert Testimony as Circumstantial Evidence
    Defendant contends the trial court erred by failing to instruct the jury, on its
    own motion, that its instructions on circumstantial evidence applied specifically to
    expert testimony. He asserts the error violated his federal and state federal
    constitutional rights to due process, trial by jury, a fair trial, and a reliable penalty
    55
    determination. (U.S. Const., 5th, 6th, 8th & 14th Amends.; Cal Const., art. I, §§ 7,
    subd. (a), 15, 16, 17.) The claim is both forfeited and meritless.
    The trial court gave two standard instructions on circumstantial evidence,
    CALJIC Nos. 2.01 and 2.02, neither of which expressly refers to expert
    testimony.12 Characterizing expert testimony as a form of circumstantial
    evidence, defendant contends the trial court should have informed the jury that the
    12      As given here, CALJIC No. 2.01 stated in full: “However, a finding of
    guilt as to any crime may not be based on circumstantial evidence unless the
    proved circumstances are not only (1) consistent with the theory that the defendant
    is guilty of the crime, but (2) cannot be reconciled with any other rational
    conclusion. [¶] Further, each fact which is essential to complete a set of
    circumstances necessary to establish the defendant‟s guilt must be proved beyond
    a reasonable doubt. In other words, before an inference essential to establish guilt
    may be found to have been proved beyond a reasonable doubt, each fact or
    circumstance on which the inference necessarily rests must be proved beyond a
    reasonable doubt. [¶] Also, if the circumstantial evidence as to any particular
    count permits two reasonable interpretations, one of which points to the
    defendant‟s guilt and the other to his innocence, you must adopt that interpretation
    that points to the defendant‟s innocence, and reject that interpretation that points to
    his guilt. [¶] If, on the other hand, one interpretation of this evidence appears to
    you to be reasonable and the other interpretation to be unreasonable, you must
    accept the reasonable interpretation and reject the unreasonable.”
    CALJIC No. 2.02, as given here, stated in full: “The specific intent and/or
    mental state with which an act is done may be shown by the circumstances
    surrounding the commission of the act. However, you may not find the defendant
    guilty of the crime charged in Counts 1, 2, or 3 unless the proved circumstances
    are not only (1) consistent with the theory that the defendant had the required
    specific intent and/or mental state but (2) cannot be reconciled with any other
    rational conclusion. [¶] Also, if the evidence as to specific intent and/or mental
    state permits two reasonable interpretations, one of which points to the existence
    of the specific intent and/or mental state and the other to its absence, you must
    adopt that interpretation which points to its absence. If, on the other hand, one
    interpretation of the evidence as to the specific intent and/or mental state appears
    to you to be reasonable and the other interpretation to be unreasonable, you must
    accept the reasonable interpretation and reject the unreasonable.”
    56
    principles expressed in those instructions applied to expert testimony. More
    specifically, he contends the court should have instructed that “if the expert
    testimony permitted two reasonable inferences, one of which points to defendant‟s
    innocence and the other to his guilt, the jury must adopt that interpretation that
    points to the defendant‟s innocence, and reject that interpretation that points to his
    guilt.”
    Defendant does not assert that the circumstantial evidence instructions were
    incorrect statements of law. “A party may not complain on appeal that an
    instruction correct in law and responsive to the evidence was too general or
    incomplete unless the party has requested appropriate clarifying or amplifying
    language.” (People v. Lang (1989) 
    49 Cal. 3d 991
    , 1024; accord, People v.
    Livingston (2012) 
    53 Cal. 4th 1145
    , 1166; People v. Lewis (2001) 
    26 Cal. 4th 334
    ,
    380.) Accordingly, the claim is forfeited.
    The claim is also without merit. Defendant cites no authority for the
    proposition that a trial court is required to specify the evidence or the issues to
    which the instructions regarding circumstantial evidence apply. And for good
    reason: how a general instruction applies to specific evidence or theories is an
    argument for counsel to make.
    6. Refused Modification of CALJIC No. 2.11.5
    Defendant contends the trial court erred when it denied his proposed
    modification to CALJIC No. 2.11.5 (Unjoined Perpetrators of the Same Crime).
    His asserts the error violated his federal and state constitutional rights to a fair
    trial, to a trial by jury, to present a defense, and to a reliable penalty determination.
    (U.S. Const., 5th, 6th, 8th & 14th Amends.; Cal Const. art. I, §§ 7, subd. (a). 15,
    16, 17.) The claim is meritless.
    57
    The trial court gave CALJIC No. 2.11.5 as follows: “There has been
    evidence in this case indicating that a person other than defendant was or may
    have been involved in the crime for which that defendant is on trial. [¶] There
    may be many reasons why that person is not here on trial. Therefore, do not
    speculate or guess as to why the other is not being prosecuted in this trial or
    whether he has been or will be prosecuted. Your sole duty is to decide whether
    the People have proved the guilt of the defendant on trial.”
    The instruction was intended to apply to defendant‟s cellmate, Gary Green,
    who participated in the attack on Addis, but was not on trial. An internal rules
    violation investigation by the Department of Corrections concluded that Green
    was involved in the conspiracy to assault Addis and noted there was information
    that Green had ordered the hit on Addis. Green was assessed a 360-day credit
    loss. However, 20 days after this disciplinary hearing, he was paroled. Based on
    this record, defendant‟s gang expert, Steven Rigg, testified that Green was not
    punished for his participation in the conspiracy.
    In light of this evidence, defense counsel requested a modification of
    CALJIC No. 2.11.5 to include the following language: “You may, however,
    consider the actions taken against Mr. Green by members of the Department of
    Corrections to the extent same have been proved in this case as they bear upon
    issues of fact which you are asked to determine.” The prosecutor, while noting the
    defense was free to argue its theory that correctional officers were complicit in the
    assault on Addis, objected to the modification of CALJIC No. 2.11.5 because it
    “takes away what this jury instruction is saying.” That is, it invited speculation as
    to why Green had not been prosecuted for the Addis murder. Defense counsel
    argued the modification “clarif[ied] the behavior of the Department of Corrections
    toward Mr. Green, independent of any prosecutorial decisions that may be relevant
    to the facts in this case.” The trial court rejected the proposed modification.
    58
    There was no error. Defendant does not contend, nor could he, that
    CALJIC 2.11.5 was either inapplicable to this case or flawed as given. (See
    People v. Brown (2003) 
    31 Cal. 4th 518
    , 560 [purpose of the instruction “ „is to
    discourage the jury from irrelevant speculation about the prosecution‟s reasons for
    not jointly prosecuting all those shown by the evidence to have participated in the
    perpetration of the charged offenses, and also to discourage speculation about the
    eventual fates of unjoined perpetrators‟ ”].) The proposed modification would
    have simultaneously instructed the jury it could not consider the prosecution‟s
    reasons for not prosecuting Green, but it could consider the actions of the
    Department of Corrections in giving him assertedly lenient punishment for his part
    in the attack on Addis. As the prosecutor here noted, this conflation of the actions
    of the District Attorney‟s Office and the Department of Corrections could only
    have confused the jury and potentially eviscerated the instruction. Accordingly,
    the trial court properly rejected the proposed modification.
    Moreover, even without the proposed modification, nothing prevented the
    defense from making its argument that the assertedly lenient treatment of Green by
    the Department of Corrections was evidence of complicity by some correctional
    officers in the attack on Addis. Therefore, his claims of error and prejudice both
    fail.
    G. Cumulative Error
    Because we have found no error in the guilt phase, there is no cumulative
    prejudice to address.
    59
    III. PENALTY PHASE CLAIMS
    A. Claims Related to Defendant’s Convictions for Assault by a Life
    Prisoner with Malice Aforethought
    1. Applicability of Section 4500 to Defendant at the Time of the
    Offenses
    Defendant contends his two convictions of assault by a life prisoner with
    malice aforethought must be reversed because he was not “undergoing a life
    sentence” (§ 4500) at the time he assaulted Addis (count 2) and Matthews (count
    3). Citing section 1170.1, which addresses when a consecutive term imposed for a
    felony committed in prison commences, defendant claims that at the time he
    committed the assaults, he was still serving a sentence for burglary, and his life
    sentence had not yet begun. He contends that his state and federal constitutional
    rights to due process, trial by jury, and a reliable penalty determination require
    reversal of his convictions. (U.S. Const., 5th, 6th, 8th & 14th Amends.; Cal.
    Const., art. I, §§ 7, subd. (a), 15, 16, 17.)
    Preliminarily, the People assert that defendant has forfeited this claim
    because he failed to make the argument below and, indeed, did not contest
    evidence presented by the prosecution in the form of prison records to prove he
    was a life prisoner at the time of the offenses. Defendant casts his claim as one of
    sufficiency of the evidence to support his convictions, and on that basis, maintains
    that such a claim may be raised for the first time on appeal. (See People v. Butler
    (2003) 
    31 Cal. 4th 1119
    , 1126 [substantial evidence claim can be raised on appeal
    even if it was not argued at trial].) Assuming, without deciding, that the claim is
    properly raised, it is without merit.
    Section 4500 states in pertinent part: “Every person while undergoing a life
    sentence, who is sentenced to state prison within this state, and who, with malice
    aforethought, commits an assault upon the person of another with a deadly weapon
    60
    or instrument, or by any means of force likely to produce great bodily injury is
    punishable with death or life imprisonment without possibility of parole” if the
    victim dies. (Italics added.) Section 1170.1, subdivision (c) (hereinafter section
    1170.1(c)) addresses when such a sentence commences if it is consecutive to a
    term already being served. It provides that when “any person [is] convicted of one
    or more felonies committed while the person is confined in the state prison . . . and
    the law either requires the terms to be served consecutively or the court imposes
    consecutive terms, the term of imprisonment for all the convictions that the person
    is required to serve consecutively shall commence from the time the person would
    otherwise have been released from prison.” (§ 1170.1(c), italics added.)
    Here the evidence shows the following: In June 1992, defendant was
    sentenced to an eight-year prison term after he pleaded guilty to first degree
    burglary. The Department of Corrections calculated his earliest release date for
    this offense would be February 10, 2000. In September 1995, while still serving
    his burglary sentence, defendant pleaded guilty to possession of a deadly weapon
    by an inmate (§ 4502) which, because it was his third strike, resulted in a sentence
    of 25 years to life with the possibility of parole, consecutive to his burglary
    sentence. In defendant‟s chronological history log maintained by the Department
    of Corrections, an entry dated November 13, 1995, states: “Life term begins
    2/10/2000.” Defendant‟s assaults on Addis and Matthews were committed in
    1997.
    Based on this record, defendant contends he was not “undergoing a life
    sentence” when he assaulted his fellow inmates in 1997; rather, he was still
    serving his burglary sentence. We rejected a similar argument in People v.
    McNabb (1935) 
    3 Cal. 2d 441
    (McNabb), which involved section 4500‟s
    predecessor, former section 246. While McNabb was on parole for two robberies
    for which he had been sentenced to two determinate sentences, he committed two
    61
    more robberies, for which he was sentenced to two terms of five years to life.
    Upon his conviction for these later robberies, his parole was revoked and he was
    required to serve the rest of the two determinate sentences. Thereafter, while
    trying to escape from prison, he killed a fellow inmate. McNabb was tried and
    sentenced to death under former section 246, which provided: “ „Every person
    undergoing a life sentence in a state prison of this state, who, with malice
    aforethought, commits an assault upon the person of another with a deadly weapon
    or instrument, or by any means of force likely to produce great bodily injury, is
    punishable with death.‟ ” (McNabb, at p. 444.)
    On appeal, McNabb contended that he was not serving a life sentence when
    he attempted to escape because his life sentences for the later robberies, being
    consecutive to the determinate sentences for the earlier robberies on which his
    parole had been revoked, had not yet commenced. We rejected his argument:
    “The fact that appellant McNabb was returned to prison upon two convictions of
    first degree robberies committed while released on parole and was required to
    serve out the uncompleted terms of imprisonment by reason of breaking the terms
    of his parole did not suspend the force of commitments upon which he was held.
    Had he been discharged or released from serving the uncompleted terms by a writ
    of habeas corpus or by pardon he would have still been held as a prisoner serving
    a life term on said later commitments. We think the contention . . . to the effect
    that a person is not undergoing a life sentence within the purpose and meaning of
    the law, when imprisoned on a judgment which imposes the longest term known to
    the law and to which nothing further may be added, because, forsooth, he is also
    held on a prior uncompleted sentence for years does not stand the test of reason.”
    
    (McNabb, supra
    , 3 Cal.2d at p. 457.)
    We dismissed the defendant‟s reliance on former section 669, which
    provided that when a person was convicted of multiple crimes, the imprisonment
    62
    for each term was to “commence at the termination of the [preceding] term of
    imprisonment.” (Former § 669, as amended by Stats. 1927, ch. 626, § 1, p.
    1056.)13 “Section 669 . . . is not germane to the subject. It has to do with time
    served in terms less than life. It does not purport to say that a person is not
    undergoing a life sentence when delivered on a certified copy of the judgment of
    conviction to the warden of the state prison. The prisoner is undergoing a life
    sentence whatever may happen and he is held as such a prisoner by virtue of said
    judgment.” 
    (McNabb, supra
    , 3 Cal.2d at p. 457.)
    Finally, we pointed out that former section 246 “was enacted as a
    disciplinary regulation and as a means of protection to prisoners themselves
    against the assaults of the vicious, and also to protect the officers who are required
    to mingle with the inmates, unarmed. . . . It is applicable to the facts of
    [McNabb‟s] case in every sense.” 
    (McNabb, supra
    , 3 Cal.2d at p. 458.)
    In reliance on our decision in McNabb, the Court of Appeal in People v.
    Superior Court (Bell) (2002) 
    99 Cal. App. 4th 1334
    (Bell), rejected a claim that a
    defendant‟s attack on another inmate did not occur while he was “undergoing a
    life sentence” (§ 4500) because he was serving a determinate term at the time of
    the attack. The court noted that the phrase “undergoing a life sentence” has
    remained constant from the enactment of former section 246 through various
    13     In 1929, when McNabb was convicted of the two later robberies, former
    section 669 provided: “When any person is convicted of two or more crimes the
    former imprisonment to which he is sentenced upon the second or other
    subsequent conviction must commence at the termination of the first term of
    imprisonment to which he shall be adjudged, or at the termination of the second or
    other subsequent term of imprisonment, as the case may be; provided, that in
    exceptional cases the judgment, in the discretion of the court, may direct that such
    terms of imprisonment, or any of them, shall run concurrently.” (Stats. 1927,
    ch. 626, § 1, p. 1056.)
    63
    amendments to section 4500, and the Legislature‟s intent has also remained the
    same — protecting guards and other prisoners from inmates who think they have
    “ „nothing left to lose‟ ” by committing crimes in prison. 
    (Bell, supra
    , 99
    Cal.App.4th at p. 1341; see 
    id. at pp.
    1340-1341, citing 
    McNabb, supra
    , 1
    3 Cal. 2d 441
    .) Bell further observed that in In re Cowen (1946) 
    27 Cal. 2d 637
    , we
    explained that former section 669, which required that judgments provide whether
    multiple terms shall be served concurrently or consecutively, does “ „not . . .
    require that for all purposes, when consecutive sentences are directed, the
    defendant shall be regarded as imprisoned on only one charge at a time.‟ ” (Bell,
    at p. 1343, quoting Cowen, at p. 648.) Bell acknowledged that former section 669
    was amended after In re Cowen was decided, but concluded that “[a]ccording to
    the plain language of section 669, the mandate that a determinate sentence be
    served before a consecutive life sentence is for the purpose of calculating parole
    eligibility, and not for the purpose of determining whether the prisoner is
    undergoing a life sentence within the meaning of section 4500.” (Bell, at p. 1343.)
    Defendant attempts to distinguish McNabb and Bell on the basis that this
    case is governed by section 1170.1(c), which specifically addresses consecutive
    sentences with respect to crimes committed while in prison, rather than section
    669, which more generally addresses concurrent and consecutive sentences. As
    noted above, section 1170.1 provides that when an individual is convicted of
    felonies in prison and consecutive sentences are imposed, “the term of
    imprisonment for all [such] convictions . . . shall commence from the time the
    person would otherwise have been released from prison.” (§ 1170.1(c).) Based on
    this language, defendant reasons that his life term under the Three Strikes law for
    possession of a weapon in prison would not have begun until the earliest date on
    which he could have been released with respect to his determinate term for the
    64
    burglaries that led to his imprisonment. He contends that date would have been
    February 10, 2000, more than two years after he assaulted Addis.
    Defendant‟s argument is unpersuasive for at least two reasons. First, it
    ignores the different language and functions of the two statutes. Section 1170.1(c)
    addresses when an inmate begins “to serve” consecutive sentences, whereas
    section 4500 addresses the punishment to be imposed for specified assaults
    committed “while undergoing a life sentence.” Section 1170.1, like section 669, is
    a technical sentencing statute that addresses the time during which an inmate is
    actually serving a particular prison term, and does not purport to have any bearing
    on the question of whether an individual is undergoing a life sentence for purposes
    of section 4500. Furthermore, we presume that in enacting section 1170.1(c), the
    Legislature was aware of not only section 4500, but also the case law broadly
    interpreting the phrase “undergoing a life sentence” in that statute. Had the
    Legislature intended for section 1170.1(c) to modify in any way the latter statute,
    it could have said so.
    Second, defendant‟s argument would undermine the shared purpose of
    sections 1170.1(c) and 4500 — deterring inmates from committing crimes in
    prison. “Section 1170.1(c) applies to felonies committed when the defendant is
    confined in a state prison. The statutory scheme makes clear that such felonies,
    i.e., those felonies committed in prison, are exempt from the general sentencing
    scheme.” (People v. White (1988) 
    202 Cal. App. 3d 862
    , 869.) The reason such
    felonies are treated differently is that “[t]he Legislature wanted in-prison crimes to
    be punished more severely than crimes committed „on the „outside.‟ ” (Ibid.) It
    would be inconsistent with the legislative purpose of these statutes to construe
    section 1170.1(c) to preclude the application of section 4500 to inmates who have
    not yet begun serving an imposed and pending life sentence because they are still
    serving a determinate sentence.
    65
    Finally, defendant contends that because his Three Strikes conviction could
    have been overturned on appeal before he began to serve it, he was not a person
    undergoing a life sentence when he assaulted Addis. Of course, any life sentence
    consecutive to a determinate sentence could potentially be modified by
    commutation, pardon, a statutory change, an ultimately successful appeal or
    habeas corpus petition, or even avoided by the death of the inmate during the
    determinant term. Such speculative outcomes do not undermine the core
    reasoning of McNabb and Bell that the phrase “undergoing a life sentence” was
    intended to encompass an inmate who is subject to such a sentence, even if he or
    she has not begun “serving” that sentence.
    2. Whether Section 4500 Sufficiently Narrows the Class of Individuals
    Eligible for the Death Penalty
    Defendant contends that section 4500 fails to sufficiently narrow the class
    of individuals eligible for the death penalty in violation of his rights to a due
    process, and a fair trial, and the proscription against cruel and unusual punishment.
    (U.S. Const., 5th, 6th, 8th & 14th Amends.; Cal. Const. art. I, §§ 7, subd. (a), 15,
    16, 17.) We disagree.
    Under section 4500, a person undergoing a life sentence is eligible for a
    death sentence if found guilty of an assault with a deadly weapon or with force
    likely to produce great bodily injury, with malice aforethought, leading to the
    death of the victim. In effect, it authorizes imposition of the death penalty for
    what could be a second degree murder, i.e., an unlawful killing with malice
    aforethought. In contrast, the vast majority of offenses eligible for the death
    penalty are various forms of first degree murder. (§ 190.2.) Nonetheless, as
    discussed below, the legislative determination that life prisoners who commit fatal
    aggravated assaults are potentially deserving of death is a venerable one; versions
    of this statute have existed for more than a century. (See former § 246, added by
    66
    Stats. 1901, ch. 12, § 1, p. 6.) Moreover, the statute is based on rationales
    involving security and deterrence in prison settings (see 
    McNabb, supra
    , 3 Cal.2d
    at p. 457; 
    Bell, supra
    , 99 Cal.App.4th at pp. 1339-1340), and California is scarcely
    alone in recognizing that killings committed by life prisoners in prison constitute a
    special class of homicide as to which the severest penalty should potentially apply.
    Section 4500 is a death eligibility statute as opposed to a death selection
    statute. (See Tuilaepa v. California (1994) 
    512 U.S. 967
    , 971-972.) A defendant
    convicted of the offense defined by section 4500 becomes eligible for the death
    penalty or its alternative, life without the possibility of parole. Thereafter, the jury
    selects the penalty following a penalty phase trial at which it considers evidence in
    aggravation and mitigation under section 190.3. The selection process requires an
    “ „individualized determination‟ ” of the appropriate penalty based on “ „the
    character of the individual and the circumstances of the crime.‟ ” (Tuilaepa, at p.
    972.) This “requirement is met when the jury can consider relevant mitigating
    evidence of the character and record of the defendant and the circumstances of the
    crime.” (Ibid.) The requirement of an individualized determination does not,
    however, apply to the eligibility stage. (Id. at p. 973.)
    The distinction between the eligibility and selection phases is significant in
    terms of the “differing constitutional treatment [the United States Supreme Court
    has] accorded those two aspects of capital sentencing. It is in regard to the
    eligibility phase that [the court has] stressed the need for channeling and limiting
    the jury‟s discretion to ensure that the death penalty is a proportionate punishment
    and therefore not arbitrary or capricious in its imposition. In contrast, in the
    selection phase, [the court has] emphasized the need for a broad inquiry into all
    relevant mitigating evidence to allow an individualized determination.”
    (Buchanan v. Angelone (1998) 
    522 U.S. 269
    , 275-276.)
    67
    “To pass constitutional muster, a capital sentencing scheme [1] must
    „genuinely narrow the class of persons eligible for the death penalty and [2] must
    reasonably justify the imposition of a more severe sentence on the defendant
    compared to others found guilty of murder.‟ ” (Lowenfield v. Phelps (1988) 
    484 U.S. 231
    , 244.) With respect to the first requirement, we note that the class of
    individuals potentially subject to the death penalty under section 4500 is quite
    circumscribed: persons serving a life sentence who, with malice aforethought,
    assault another with a deadly weapon or instrument, or by any means of force
    likely to produce great bodily injury, resulting in the death of the victim within a
    year and a day. (See Woodson v. North Carolina (1976) 
    428 U.S. 280
    , 287, fn. 7
    [describing as “an extremely narrow category of homicide” “murder [committed]
    by a prisoner serving a life sentence”].) The statute easily satisfies the
    requirement that an eligibility factor “apply only to a subclass of defendants
    convicted of [homicide].” (Tuilaepa v. 
    California, supra
    , 512 U.S. at p. 972.)
    With respect to the second requirement — reasonable justification for a
    more severe sentence — we reiterate that the Legislature has determined that death
    eligibility for life prisoners who commit an aggravated assault that leads to the
    victim‟s death is required to “protect[] [their fellow] prisoners . . . against the
    assaults of the vicious, and also to protect the officers who are required to mingle
    with the inmates, unarmed.” 
    (McNabb, supra
    , 3 Cal.2d at p. 458; accord, 
    Bell, supra
    , 99 Cal.App.4th at p. 1341.) By imposing more severe penalties on those
    serving life sentences, “the Legislature was attempting to deter severely violent
    crime by those who might otherwise think themselves immune from punishment
    because they were already lifetime guests of the state penal system.” (In re
    Carmichael (1982) 
    132 Cal. App. 3d 542
    , 546.) Along with retribution, deterring
    attacks by life prisoners and thereby promoting the safety of inmates and
    correction officers are legitimate penal objectives. (See Kennedy v. Louisiana
    68
    (2008) 
    554 U.S. 407
    , 420 (Kennedy) [“punishment is justified under one or more
    of three principal rationales: rehabilitation, deterrence, and retribution”].) These
    rationales of institutional security, deterrence, and retribution provide a reasonable
    justification for distinguishing this category of murder from others to which the
    death penalty does not apply.
    Defendant contends section 4500 fails to sufficiently narrow the subclass of
    defendants eligible for the death penalty because it does not distinguish between
    different types of life prisoners, such as those serving a life term for murder and
    someone like him whose life sentence was imposed under the Three Strikes law
    for nonviolent felonies.14 There is no requirement at the eligibility stage that a
    narrowly circumscribed class of defendants for whom the death penalty is
    reasonably justified be further distinguished according to the particular
    circumstances that led to their eligibility. Rather, that is a question that goes to the
    selection stage and its individualized determination requirement. Only at that
    point does the Eighth Amendment require “a broad inquiry into all relevant
    mitigating evidence to allow an individualized determination.” (Buchanan v.
    
    Angelone, supra
    , 522 U.S. at p. 276.) Although the reason why a defendant was a
    life prisoner at the time of the violation of section 4500 may be a relevant
    consideration for the jury at the selection stage, that reason is irrelevant to the
    justification for including such persons in the death-eligible class; the reasons
    underlying section 4500 apply with equal force to life prisoners who have
    14      Defendant‟s life sentence was imposed as a result of his 1995 guilty plea to
    a third strike of possession of a weapon in prison (§ 4502) and his admission to
    two prior felony convictions for burglary.
    69
    committed prior violent crimes and those who face lifetime imprisonment for
    nonviolent offenses.15
    Defendant next argues that “[d]evelopments since [prior] decisions
    upholding [earlier versions of] section 4500 and its predecessor statutes have
    undermined the retribution, deterrence and safety rationales offered to justify
    death eligibility on life prisoner status.” In essence, defendant‟s claim is that,
    because prior versions of section 4500 would not pass constitutional muster in
    light of evolving Eighth Amendment jurisprudence, the underlying legislative
    justifications for punishing life prisoners who, with malice aforethought, commit
    fatal assaults in prison have also been eroded over time. As explained below, the
    argument fails because the legislative justifications remain valid.
    Until 1977, section 4500 and its predecessor, former section 246, mandated
    the death penalty for life prisoners who committed an aggravated assault,
    regardless of whether the victim died. The original statute, enacted in 1901,
    provided: “Every person undergoing a life sentence in a state prison of this state,
    who, with malice aforethought, commits an assault upon the person of another
    with a deadly weapon or instrument, or by any means of force likely to produce
    great bodily injury, is punishable with death.” (Stats. 1901, ch. 12, § 1, p. 6.) In
    15      Defendant‟s reliance on Tuilaepa v.
    California, supra
    , 
    512 U.S. 967
    , is
    misplaced. As he concedes, Tuilaepa concerns death selection, not death
    eligibility. Moreover, Tuilaepa‟s observation that some sentencing factors may be
    unconstitutionally vague if they lack “some „common-sense core of meaning . . .
    that criminal juries should be capable of understanding‟ ” (
    id. at p.
    975) does not
    support defendant‟s assertion that section 4500 is unconstitutionally vague. As
    Tuilaepa itself notes, “[t]he eligibility decision fits the crime within a defined
    classification.” (Id. at p. 973.) Section 4500 meets this standard. Similarly,
    Godfrey v. Georgia (1980) 
    446 U.S. 420
    , also cited by defendant, involved a
    vagueness challenge to a sentencing factor. (Id. at pp. 422-423.)
    70
    1941, section 246 was repealed and reenacted, renumbered as section 4500, but
    textually remained substantially the same. (Stats. 1941, ch. 106, §§ 1, 15, pp.
    1080, 1124.) In 1977, following the restoration of the death penalty in California
    (see People v. Frierson (1979) 
    25 Cal. 3d 142
    , 172-175), section 4500 was
    amended to its present form. The amendment eliminated the mandatory death
    penalty provision and limited eligibility for the death penalty to aggravated
    assaults with malice aforethought resulting in death, with the alternative of life
    without the possibility of parole. (Stats. 1977, ch. 316, § 21, p. 1264.)
    Defendant cites a number of decisions by this court upholding those earlier
    and now superseded versions of the statute against various constitutional
    challenges (see, e.g., People v. Vaughn (1969) 
    71 Cal. 2d 406
    , 418 [imposition of
    death penalty under section 4500 for an assault that did not result in the death of
    the victim did not violate the Eighth Amendment‟s proscription against cruel and
    unusual punishment]; People v. Wells (1949) 
    33 Cal. 2d 330
    , 337 [holding that
    mandatory death penalty imposed under section 4500 on prisoner serving an
    indeterminate sentence “infringes no constitutional limitation”]; People v. Finley
    (1908) 
    153 Cal. 59
    [upholding mandatory death penalty imposed on a life term
    defendant convicted under former section 246 against an equal protection
    challenge to the statute]), and asserts that none of these earlier decisions would
    survive scrutiny under current Eighth Amendment jurisprudence because the
    Eighth Amendment now prohibits the death penalty for nonfatal assaultive crimes,
    and also prohibits mandatory death penalty statutes. (See, e.g., 
    Kennedy, supra
    ,
    
    554 U.S. 407
    [striking down a statute authorizing the death penalty for rape of a
    child]; Woodson v. North 
    Carolina, supra
    , 
    428 U.S. 280
    [striking down statute
    making the death penalty mandatory for first degree murder]; Graham v. Superior
    Court (1979) 
    98 Cal. App. 3d 880
    [declaring unconstitutional a 1973 version of
    section 4500 that contained a mandatory death penalty provision].) From this
    71
    premise, he contends that the legislative justifications offered in support of the
    statute in our earlier opinions — deterrence, retribution, and institutional security
    — have been eroded and are now constitutionally suspect.
    Defendant‟s logic is flawed and the cases on which he relies are inapposite.
    Decisions rejecting constitutional challenges to prior versions of the statute
    containing elements that would no longer be constitutionally permissible are
    obviously not controlling in our examination of the current version of the statute.
    Nonetheless, the discussions in those earlier decisions of the threats of violence
    posed by prisoners sentenced to life terms as justification for the policy of
    potentially imposing the death penalty on them remain valid and support the
    current version of section 4500.16 The United States Supreme Court continues to
    recognize that penal statutes may legitimately rest on one or more of “three
    principal rationales: rehabilitation, deterrence, and retribution” (
    Kennedy, supra
    ,
    554 U.S. at p. 420.) Section 4500, as already noted, singles out a particular
    subclass of defendants who commit lethal assaults with malice aforethought —
    those imprisoned for life — and makes them eligible for the death penalty because
    the Legislature has determined their particular status as life prisoners requires this
    exceptional measure to protect correctional officers and other inmates. With the
    16      For example, in People v. 
    Finley, supra
    , 153 Cal. at page 61, this court
    observed that “it has long been a part of judicial knowledge, of legislative
    knowledge, and, indeed, of general knowledge, that convicts in penal institutions
    undergoing sentences for life, constitute a most reckless and dangerous class. The
    conditions of their sentences destroy their hopes and with the destruction of hope
    all bonds of restraint are broken and there follows a recklessness leading to brutal
    crimes. . . . They were crimes of violence committed not alone against fellow
    inmates, but upon the custodians, officers, and guards of the institutions. . . .
    Under this well-recognized condition of affairs it seemed expedient to the
    legislature to meet the situation by the enactment of section 246 of the Penal
    Code.”
    72
    growth in the prison population and prison gangs, this rationale applies with equal
    or greater force today compared to when it was first articulated over a hundred
    years ago. Accordingly, we reject defendant‟s assertion that the statute‟s rationale
    has been superseded or undermined merely because earlier versions of the statute
    would no longer pass constitutional muster.
    The opinion upon which defendant places primary reliance, Sumner v.
    Shuman (1987) 
    483 U.S. 66
    , is inapposite. In Sumner, the United States Supreme
    Court declared unconstitutional a Nevada statute that mandated the death penalty
    for prisoners who committed murder while undergoing a sentence of life without
    the possibility of parole. Under Nevada law, life without the possibility of parole
    could be imposed for crimes other than murder, such as kidnapping, rape and
    battery with substantial bodily harm. (Id. at pp. 80-81.) The Supreme Court noted
    that under those circumstances, “[w]ithout consideration of the nature of the
    predicate life-term offense and the circumstances surrounding the commission of
    that offense, the label „life-term inmate‟ reveals little about the inmate‟s record or
    character.” (Id. at p. 81.) The court further noted that “a guided-discretion
    sentencing procedure does not undermine any deterrent effect that the threat of the
    death penalty may have” (
    id. at p.
    83), and that a guided-discretion procedure does
    not necessarily allow an inmate to avoid retribution (
    id. at pp.
    83-84). The court
    did not, however, question the legitimacy of deterrence and retribution as
    rationales. In short, the statute in Sumner differs from section 4500 in crucial
    respects, and defendant‟s reliance on Sumner is misplaced.
    Defendant also cites two studies assertedly demonstrating that the death
    penalty has an insignificant deterrent effect on prison murders.17 The weight and
    17    Defendant cites Sorensen & Pilgrim, An Actuarial Risk Assessment of
    Violence Posed by Capital Murder Defendants (2000) 90 J. Crim. L. &
    (footnote continued on next page)
    73
    validity of such studies involve policy questions within the Legislature‟s purview.
    So, too, do defendant‟s arguments regarding retributive steps short of death that
    might be taken against prisoners who kill. These studies do not establish that
    imposing death eligibility on life prisoners who commit fatal aggravated assaults
    is constitutionally impermissible.
    Next, defendant contends that an “interjurisdictional comparison
    demonstrates a lack of societal consensus that a murder by a life prisoner”
    deserves the death penalty. We are not persuaded.
    In evaluating whether there was a consensus against making the crime of
    rape of a child punishable by death, the United States Supreme Court examined
    both “[t]he history of the death penalty for the crime of rape” and the current
    status of such statutes in the United States. (
    Kennedy, supra
    , 554 U.S. at p. 422.)
    The court traced an historical movement away from imposing the death penalty for
    rape from its high point in 1925 when 18 states, the District of Columbia and the
    federal government had such statutes, to the post-Furman (Furman v. Georgia
    (1972) 
    408 U.S. 238
    ) landscape, when only Louisiana and five other states had
    reenacted such statutes. The court further noted that the statutes of four of those
    states were more restrictive than Louisiana‟s law, because they required a prior
    conviction for rape as a condition for death eligibility while the remaining state,
    Georgia, required aggravating circumstances including, but not limited to, a prior
    conviction. (
    Kennedy, supra
    , 554 U.S. at p. 423.) “By contrast, 44 States have
    not made child rape a capital offense. As for federal law, Congress in the Federal
    (footnote continued from previous page)
    Criminology 1251, and Marquart & Sorensen, A National Study of the Furman-
    Commuted Inmates: Assessing the Threat to Society from Capital Offenders
    (1989) 23 Loyola L.A. L.Rev. 5.
    74
    Death Penalty Act of 1994 expanded the number of federal crimes for which the
    death penalty is a permissible sentence, including certain nonhomicide offenses;
    but it did not do the same for child rape or abuse. [Citation.] Under 18 U.S.C.
    § 2245, an offender is death eligible only when the sexual abuse or exploitation
    results in the victim‟s death.” (Ibid.)
    The court drew comparisons between these statistics and those it had
    examined in three earlier cases in which it had held the death penalty
    unconstitutional when imposed upon certain types of aiders and abettors to felony
    murder (Enmund v. Florida (1982) 
    458 U.S. 782
    ), the intellectually disabled
    (Atkins v. 
    Virginia, supra
    , 
    536 U.S. 304
    ), and juveniles (Roper v. Simmons (2005)
    
    543 U.S. 551
    ). (
    Kennedy, supra
    , 554 U.S. at pp. 425-426.) As in those cases, the
    court‟s survey led it to conclude that the “evidence of a national consensus with
    respect to the death penalty for child rapists . . . shows divided opinion but, on
    balance, an opinion against it.” (Id. at p. 426.) The court concluded: “After
    reviewing the authorities informed by contemporary norms, including the history
    of the death penalty for this and other nonhomicide crimes, current state statutes
    and new enactments, and the number of executions since 1964, we conclude there
    is a national consensus against capital punishment for the crime of child rape.”
    (Id. at p. 434.)
    As an initial matter, it is significant that the court in Kennedy explicitly and
    repeatedly referred to the fact that the statute at issue authorized the death penalty
    for a crime that, while still devastating for the victim, did not result in the victim‟s
    death. (See, e.g., 
    Kennedy, supra
    , 554 U.S. at p. 435 [acknowledging that “there
    are moral grounds to question a rule barring capital punishment for a crime against
    an individual that did not result in death”]; 
    id. at p.
    437 [“the death penalty should
    not be expanded to instances where the victim‟s life was not taken”]; 
    id. at p.
    439
    [recognizing the possibility of arbitrary results in cases of heinous crimes that may
    75
    “overwhelm a decent person‟s judgment” and refusing to “sanction this result
    when the harm to the victim, though grave, cannot be quantified in the same way
    as death of the victim”].) Of course, for a violation of section 4500 to be death
    eligible, the victim must die (within a year and a day) from the assault.
    Accordingly, a major aspect of the court‟s reasoning in Kennedy does not apply
    here.
    Defendant nonetheless contends that there is no “societal consensus” to
    support imposition of death for a life prisoner who kills. In support of his claim,
    he cites the high court‟s decisions in Kennedy, Roper, Atkins, and Enmund, but his
    analysis bears only a superficial resemblance to those opinions‟ rigorous
    examination of historical, judicial, and legislative trends regarding the existence of
    an evolving national consensus against authorization of imposition of the death
    penalty on a class of defendants. Instead, he rests his argument solely on his
    assertion that 75 percent of American jurisdictions have rejected using prisoner
    status to determine death eligibility. His statistical reading is tendentious. In fact,
    based on his statistics, it is more accurate to say that the vast majority of
    jurisdictions with the death penalty regard custody status as a significant factor in
    either death penalty eligibility or death penalty selection, or for both purposes. Of
    the 31 states and the federal government whose laws currently authorize
    imposition of the death penalty, the laws of 29 states and the federal government
    use custody status as a death-eligibility or a death-selection factor, or both. It
    appears that only Nebraska and South Carolina do not explicitly include custodial
    status as a death-eligibility or selection factor.
    Defendant does not cite, nor has our research found, a single judicial
    decision from any death penalty jurisdiction that has held that the use of custodial
    status as either an eligibility or a selection factor for the death penalty violates the
    Eighth Amendment. Nor has defendant shown that any jurisdiction that reenacted
    76
    the death penalty following Furman v. 
    Georgia, supra
    , 
    408 U.S. 238
    , omitted
    custodial status as either an eligibility or selection factor for purposes of the death
    penalty. Thus, defendant fails to demonstrate the existence of an historical
    trajectory supporting a conclusion that the majority, or, indeed, any, of the death
    penalty jurisdictions has abandoned custody status as a factor for imposing the
    death penalty.
    Instead, defendant attempts to parse the statistical evidence to argue that we
    should look only at states whose statutes mirror section 4500, that is, statutes that
    use life term status as an eligibility factor and apply the death penalty to killings
    that do not rise to the level of first degree murder. Using this metric, defendant
    concludes that only eight states have a law comparable to section 4500.
    However, the question here is whether custodial status is used by a majority
    of jurisdictions as a basis for potentially imposing the death penalty, not how
    individual jurisdictions use that factor. In other words, is there a consensus that
    the death penalty is not an appropriate punishment for a fatal aggravated assault by
    a life prisoner? Moreover, in this case, where defendant was also convicted of
    first degree murder, he would have faced the death penalty in every jurisdiction
    that uses custodial status as either an eligibility or selection factor. Even granting
    that only a few states have statutes mirroring section 4500, this number is
    meaningless without a rigorous analysis of the type undertaken by the United
    States Supreme Court, which examines not simply numbers, but statutory history
    and relevant judicial and legislative actions, to answer the national consensus
    question. Defendant provides none of that, and as mentioned, we have uncovered
    nothing that suggests a majority of the country rejects the death penalty in
    circumstances covered by section 4500.
    Finally, defendant asserts the status of life prisoner is overbroad because it
    does not further distinguish between those inmates whose life sentence was the
    77
    result of a violent crime and those, like himself, whose life sentence is premised
    on a Third Strike as to which the predicate crimes were nonviolent felonies.
    As noted earlier, however prisoners subject to life sentences came to hold
    that status, they are a small and distinct subclass of those who commit homicides
    punishable as murder. Additionally, the rationale for making such defendants
    death eligible — to deter and punish crimes by individuals acting under the belief
    they have nothing left to lose — applies to all life prisoners regardless of the
    reason for their life sentences. Furthermore, to the extent the reasons for a
    defendant‟s life sentence might mitigate his or her punishment, that is an issue that
    can be raised at the penalty phase.
    For these reasons, we reject defendant‟s constitutional challenge to section
    4500‟s death eligibility provision.
    B. Prosecutorial Discretion in Seeking Death Penalty
    Defendant contends that prosecutorial discretion in seeking the death
    penalty violates his federal and state constitutional rights to due process and equal
    protection, and constitutes “the arbitrary and capricious enforcement of the death
    penalty.” (U.S. Const., 5th, 8th & 14th Amends.; Cal. Const., art. I, § 7, subd,
    (a).)
    We have consistently held that “prosecutorial discretion to select those
    eligible cases in which the death penalty actually will be sought does not, in and of
    itself, evidence an arbitrary and capricious capital punishment system, nor does
    such discretion transgress the principles underlying due process of law, equal
    protection of the laws, or the prohibition against cruel and unusual punishment.”
    (People v. Crittenden (1994) 
    9 Cal. 4th 83
    , 152.) As we explained in an early
    decision addressing the issue: “Many circumstances may affect the litigation of a
    case chargeable under the death penalty law. These include factual nuances,
    78
    strength of evidence, and, in particular, the broad discretion to show leniency.
    Hence, one sentenced to death under a properly channeled death penalty scheme
    cannot prove a constitutional violation by showing that other persons whose
    crimes were superficially similar did not receive the death penalty. [Citations.]
    The same reasoning applies to the prosecutor‟s decisions to pursue or withhold
    capital charges at the outset.” (People v. Keenan (1988) 
    46 Cal. 3d 478
    , 506.) In
    subsequent cases, we rejected the argument that we should reexamine this holding
    in light of the high court‟s voting rights decision in Bush v. Gore (2000) 
    531 U.S. 98
    . (People v. Bennett (2009) 
    45 Cal. 4th 577
    , 629, fn. 19.) We continue to adhere
    to that holding. (See, e.g., People v. Bryan, Smith and Wheeler (2014) 
    60 Cal. 4th 335
    , 469; People v. Scott (2011) 
    52 Cal. 4th 452
    , 495; People v. Gamache (2010)
    
    48 Cal. 4th 347
    , 406.) Nothing in defendant‟s arguments persuades us that our
    earlier rulings were incorrect. Furthermore, the reasoning of those cases applies
    with equal force to the exercise of prosecutorial discretion to seek the death
    penalty under section 4500.
    C. Admission of Evidence of Defendant’s Criminal History
    Defendant contends the trial court abused its discretion when it allowed the
    prosecutor to elicit from a defense expert on cross-examination details of
    defendant‟s theft-related prior offenses and juvenile adjudications. He contends
    the ruling also violated his federal and state constitutional rights to due process, a
    fair trial, trial by jury, and a reliable penalty determination. (U.S. Const., 5th, 6th,
    8th & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a). 15, 16, 17.) The claim is
    meritless.
    1. Background
    James Cuevas testified for the defense in his capacity as a casework
    specialist for the California Youth Authority (CYA), now known as the California
    79
    Division of Juvenile Justice, a position he likened to that of a social worker.
    Cuevas described his function as providing “diagnostic evaluations for the court”
    and the CYA. Although not a psychologist, his academic credentials included
    courses in psychology and “some basic understanding of various mental health
    issues.” His formal degree was a masters in social work.
    In 1987, defendant, then 19 years old, pleaded guilty to two counts of
    burglary and one count of grand theft auto. Although an adult, the court referred
    defendant to the CYA in lieu of state prison under a statute that allowed the
    transfer of individuals under 21 to the CYA. Cuevas led the team that assessed
    defendant to determine “a treatment plan and also potential placement for his
    benefit.” This assessment was memorialized in a 97-page document labeled
    Daniel Landry Mental Health Records. On direct examination, Cuevas reviewed
    the report and testified generally to its observations and conclusions regarding
    defendant‟s mental health and treatment plan. For example, he testified about
    defendant‟s troubled family life, including the fact that his parents were both deaf
    and had emotional problems. He also stated that defendant reported he had been
    sexually molested on two occasions. He reviewed defendant‟s placements as a
    juvenile in institutions for juveniles with emotional problems, and he reported that
    defendant told him he had escaped from juvenile hall. Cuevas recounted that
    defendant seemed depressed and suicidal, and that he had recommended that
    defendant receive intensive individual therapy as well as group therapy and be
    enrolled in educational and vocational programs.
    Over defendant‟s objection, and following an Evidence Code section 402
    hearing, the trial court allowed the prosecutor to cross-examine Cuevas about the
    details of the three offenses for which defendant was referred to the CYA, as well
    as prior juvenile theft-related adjudications. At the evidentiary hearing, Cuevas
    stated that defendant‟s criminal history was “[e]xtremely important” to his
    80
    assessment of defendant and his recommendations as to treatment and placement.
    In addition, in response to a question from the court, he explained that the specific
    details of a prior offense were relevant to a treatment plan “because we may send
    him to a placement program . . . that will deal with individuals with that particular
    problem. . . . So we look at the pattern of behavior.”
    On cross-examination, Cuevas again stated that a person‟s criminal history
    was very important to his assessment and recommendations because it factored
    into the decision about placement and treatment. He explained that defendant‟s
    history of “thievery” demonstrated he was “a chronic, habitual offender,” for
    whom earlier attempts at intervention had failed. He testified that, as a juvenile,
    defendant had been provided with various opportunities for rehabilitation after
    juvenile petitions charging theft-related offenses had been sustained against him.
    Cuevas explained that defendant‟s prior criminal history and prior placements
    were relevant to his future placement because it “sort of, you know, curtails the
    type of . . . trust we can . . . provide for him . . . within the facility.” The
    prosecutor then led Cuevas through defendant‟s current and prior convictions and
    juvenile adjudications in detail. This testimony addressed sustained juvenile
    petitions for burglary when defendant was 15 years old and when he was 16 years
    old, as well as details of his then-current offenses. Based on that history, Cuevas
    concluded that defendant was a “chronic habitual offender.” In light of this,
    Cuevas had recommended that defendant be placed in a “closed, locked setting” at
    which he would “be supervised every minute of his life.”
    2. Discussion
    Defendant contends the trial court abused its discretion when it allowed the
    prosecutor to cross-examine Cuevas about the details of defendant‟s prior theft-
    related convictions and juvenile adjudications, because they did not involve the
    81
    use or attempted use or threat of violence and were thus inadmissible as a factor in
    aggravation under section 190.3, factor (b). He contends further that the testimony
    was irrelevant because the details of defendant‟s criminal history were “not
    important to [Cuevas‟s] clinical impressions and his long-range custodial plans.”18
    Regarding defendant‟s first argument, the evidence of his theft-related
    criminal history was not presented by the prosecution pursuant to section 190.3,
    factor (b) but was, instead, proper rebuttal to the defense case in mitigation.
    “Rebuttal evidence is relevant and admissible if it tends to disprove a fact of
    consequence on which the defendant has introduced evidence. . . . The trial court
    has broad discretion to determine the admissibility of rebuttal evidence and, absent
    palpable abuse, an appellate court may not disturb the trial court‟s exercise of that
    discretion.” (People v. Valdez (2012) 
    55 Cal. 4th 82
    , 169; see People v. Mitcham
    (1992) 
    1 Cal. 4th 1027
    , 1072-1073 [evidence of the defendant‟s juvenile
    adjudications were admissible to rebut evidence of his good character and, as such,
    was “not subject to the notice requirement of section 190.3 and need not relate to
    any specific aggravating factor under section 190.3”].)
    We also reject defendant‟s contention that the evidence of his criminal
    record was irrelevant because it was not an important part of Cuevas‟s assessment
    and treatment plan for defendant. Cuevas himself repeatedly testified that
    defendant‟s prior record was an important aspect of his assessment and
    18     Additionally, he argues that defendant‟s juvenile adjudications were
    inadmissible as prior convictions under Apprendi v. New Jersey (2000) 
    530 U.S. 466
    and its progeny. His reply brief acknowledges this argument is foreclosed by
    our decision in People v. Nguyen (2009) 
    46 Cal. 4th 1007
    , but he urges us to
    reconsider it. We decline to do so.
    82
    recommendations, giving as an example how defendant‟s prior record of thievery
    would have affected the degree of security and supervision he would require.
    More generally, the evidence was relevant to rebut the sympathetic portrait
    defendant was attempting to paint of himself for the jury. The defense called
    Cuevas to further its overall depiction of defendant as the victim of a grossly
    abusive family who, as a result, suffered from severe emotional and psychological
    problems that mitigated his current offense. The defense sought to do so by
    selectively questioning Cuevas about his evaluation of defendant, focusing on his
    chaotic family background and depressed mental state. The prosecution was
    entitled to rebut this characterization that defendant was a victim by demonstrating
    that Cuevas‟s assessment also included his view that defendant was a habitual
    chronic offender who had failed in previous attempts at rehabilitation.19 Thus, the
    trial court did not abuse its discretion in permitting the prosecution to question
    Cuevas about defendant‟s prior criminal record in order “to present a more
    balanced picture of the defendant‟s personality.” (People v. 
    Valdez, supra
    , 55
    Cal.4th at p. 170.)
    19     Defendant quotes a sentence from In re Lucas (2004) 
    33 Cal. 4th 682
    , in
    which we said, “Evidence that a defendant suffered abuse in childhood generally
    does not open the door to evidence of defendant‟s prior crimes or other
    misconduct.” (Id. at p. 733.) In Lucas, we granted the defendant‟s petition for a
    writ of habeas corpus based on his claim that his trial attorney was constitutionally
    ineffective for failing to investigate or present mitigating evidence of abuse he
    suffered as a child. The sentence defendant quotes was in connection with our
    discussion regarding prejudice and our comment that the respondent had not
    offered any theory under which evidence of the abuse defendant suffered as a
    child would, in and of itself, have opened the door to rebuttal evidence. (Ibid.)
    That observation has no bearing on the present case, which is distinguishable both
    legally and factually.
    83
    D. Admission of Razor Blade Evidence
    Defendant contends the admission of evidence that he was in possession of
    a razor blade discovered in his cell during the penalty phase trial was an abuse of
    discretion and violated his federal and state constitutional rights to due process, a
    fair trial, trial by jury, and reliable capital sentencing proceedings. (U.S. Const.,
    5th, 6th, 8th & 14th Amends.; Cal. Const., art. I, §§ 7, subd. (a), 15, 16, 17.) The
    contention is meritless.
    In a search of defendant‟s cell during the penalty phrase trial, a razor blade
    was discovered on a table. Defendant was not permitted to possess razor blades.
    The prosecution sought to present evidence of this incident under section 190.3,
    factor (b), which allows evidence of criminal activity which “[i]nvolved the use or
    attempted use of force or violence or the express or implied threat to use force or
    violence.” The prosecution argued that defendant‟s possession of the razor blade
    violated section 4502, subdivision (a), which prohibits possession, custody or
    control of a weapon, including “any dirk or dagger or sharp instrument” by a
    person confined in any penal institution. Over the defense‟s objection, the trial
    court admitted the evidence.
    Defendant contends the trial court abused its discretion because there was
    no evidence he intended to use the razor blade to attack anyone and, therefore, his
    possession did not constitute the use or attempted use of or express or implied
    threat to use violence. We previously rejected this argument in People v. Wallace
    (2008) 
    44 Cal. 4th 1032
    , in which the defendant similarly argued that simple
    possession of a razor blade, without evidence that he had threatened to use it, is
    not admissible under section 190.3, factor (b). “As we have previously explained,
    „mere possession of a potentially dangerous weapon in custody involves an
    implied threat of violence . . . .‟ [Citation.] The circumstances of defendant‟s
    possession of the contraband, particularly when viewed together with his overall
    84
    conduct while in custody — which included five rules violations for fighting —
    lead us to conclude that the trial court did not abuse its discretion in admitting the
    evidence of defendant‟s razor possession under section 190.3, factor (b).”
    (Wallace, at p. 1082.)
    As noted above, in this case, the prosecution introduced evidence that
    defendant had, on numerous occasions, possessed prison-made slashing
    instruments and had used them to attack fellow inmates. At least one of these
    weapons had been fashioned out of a razor blade. The trial court clearly did not
    act outside the bounds of reason in concluding defendant‟s possession of the razor
    blade discovered in his cell during the penalty phase trial could constitute evidence
    of a threat of violence. In these circumstances, the court acted well within its
    discretion when it admitted the razor blade evidence under section 190.3,
    factor (b).
    E. Admission of Criminal Activity Beyond the Statute of Limitations
    Defendant contends the admission of 18 prior criminal incidents under
    section 190.3, factor (b) was barred by the statute of limitations. As he concedes,
    however, we have repeatedly rejected this argument. “ „[N]either remoteness nor
    the expiration of the statutory limitations period bars admission of a defendant‟s
    prior unadjudicated criminal activity for purposes of section 190.3, factor (b).‟ ”
    (People v. Famalaro (2011) 
    52 Cal. 4th 1
    , 42, quoting People v. Medina (1995) 
    11 Cal. 4th 694
    , 772.) Defendant‟s arguments do not persuade us that reconsideration
    of these decisions is warranted.
    F. Claims of Instructional Error
    1. Instruction on Defenses to Criminal Activity and Defendant’s
    Mental Health Evidence
    Defendant contends the trial court‟s failure to instruct the jury, on the
    court‟s own motion, to consider certain defenses to certain unadjudicated criminal
    85
    activity introduced by the prosecution under section 190.3, factor (b), after the
    court granted the prosecution‟s request to instruct on the elements of those
    offenses, violated his federal and state constitutional rights to due process, a fair
    trial, trial by jury, and reliable capital sentencing proceedings. (U.S. Const., 5th,
    6th, 8th & 14th Amends.; Cal. Const., art I, §§ 7, subd. (a), 15, 16, 17.)
    Specifically, he contends the trial court should have instructed the jury that self-
    defense against the use of excessive force was a defense to an incident on October
    21, 1994, during which defendant was forcibly extracted from his cell after
    refusing to return his food tray. Furthermore, he contends the trial court should
    have instructed the jury to consider the impact of his mental health issues on all
    factor (b) evidence. The claim is meritless.
    Over the defense‟s objection, the trial court agreed to instruct the jury on
    the elements of the section 190.3, factor (b) offenses. The defense did not request
    any further instruction on these offenses and none was given.
    Preliminarily, the People contend defendant has forfeited this claim because
    he assertedly had a tactical reason for not requesting additional instruction — he
    wanted to minimize the jury‟s focus on his criminal activity. “When defense
    counsel makes a „ “conscious, deliberate tactical choice” ‟ to request [or object to]
    an instruction, any error in the giving [or refusal to give] the instruction is invited
    and cannot be raised on appeal.” (People v. Catlin (2001) 
    26 Cal. 4th 81
    , 150.)
    However, defendant‟s objection was only to the prosecutor‟s request to instruct the
    jury on the elements of the offenses. This limited objection does not bar
    defendant‟s present claim, which relates to the trial court‟s further duty, once it
    agreed to give the elements instruction, to “instruct sua sponte on legally available
    defenses.” (People v. Montiel (1993) 
    5 Cal. 4th 877
    , 942.)
    In prior decisions, we have assumed without deciding that when the trial
    court gives an instruction on the elements of section 190.3, factor (b) offenses,
    86
    those instructions should include any applicable defenses. (People v. 
    Montiel, supra
    , 5 Cal.4th at p. 942; see, also, People v. Cain (1995) 
    10 Cal. 4th 1
    , 72.)
    Nonetheless, the court is under no obligation to provide such instruction unless
    “such defenses are supported by substantial evidence.” (People v. Montiel, at
    p. 942.) “Substantial evidence is evidence sufficient to „deserve consideration by
    the jury,‟ that is, evidence that a reasonable jury could find persuasive.” (People
    v. Barton (1995) 
    12 Cal. 4th 186
    , 201, fn. 8.) Defendant fails to identify such
    evidence. He does no more than repeat his version of the circumstances under
    which correctional officers were forced to remove him from his cell after he
    refused to return his food tray and refused to come out peaceably. Thus, no self-
    defense instruction was warranted.
    With respect to his claim that the trial court should have instructed the jury
    to consider evidence of his mental health problems as they bore on the section
    190.3, factor (b) evidence, defendant fails to demonstrate how such evidence
    would have comprised a legal defense to any of those offenses. Rather, he
    contends that such evidence was a potentially mitigating factor and the jury should
    have been so instructed. Such instruction was given in the form of an instruction
    patterned on section 190.3, factor (k). The jury was told it could consider in
    mitigation “any sympathetic or any aspect of the defendant‟s character or record
    that the defendant offers as a basis for a sentence less than death, whether or not
    related to the offense for which he is on trial.” Furthermore, in discussing the
    factor (b) evidence, defense counsel specifically argued that the evidence of
    defendant‟s mental health issues and the failure of correctional authorities to
    respond to his request for treatment “remarkabl[y] diminished the weight of
    [factor (b)] material.” Accordingly, the jury was instructed it could consider this
    evidence, and defense counsel explicitly urged them to do so.
    87
    Defendant asserts, however, that the section 190.3, factor (k) instruction
    was insufficient to direct the jury to the particular issue of the effect of his mental
    illness as it related to the section 190.3, factor (b) evidence. That claim is forfeited
    by his failure to seek clarification or amplification of the instruction. (People v.
    Lang (1989) 
    49 Cal. 3d 991
    , 1024 [“A party may not complain on appeal that an
    instruction correct in law and responsive to the evidence was too general or
    incomplete unless the party has requested appropriate clarifying or amplifying
    language”].)
    2. CALJIC No. 8.87
    Defendant contends CALJIC No. 8.87, which addresses evidence related to
    section 190.3, factor (b), is flawed because (1) it creates a mandatory presumption
    of violence and (2) it fails to require that jurors unanimously agree that defendant
    committed the factor (b) criminal activity.20 We have previously rejected these
    challenges to the instruction. (People v. 
    Butler, supra
    , 46 Cal.4th at pp. 871-872
    [CALJIC No. 8.87 does not create a mandatory presumption]; People v. Zambrano
    (2007) 
    41 Cal. 4th 1082
    , 1181-1182 [unanimity not required].) Nothing in
    defendant‟s argument persuades us to revisit these conclusions.
    20      In pertinent part, the jury was instructed as follows: “Evidence has been
    introduced for the purpose of showing that the defendant has committed the
    following criminal acts or activities . . . all of which involved the express or
    implied use of force or violence or the threat of force or violence. Before a juror
    may consider any criminal activity as an aggravating circumstance in this case, a
    juror must be satisfied beyond a reasonable doubt that the defendant . . . did in fact
    commit the criminal activity. A juror may not consider any evidence of any other
    criminal activity as an aggravating circumstance. [¶] It is not necessary for all
    jurors to agree. If any juror is convinced beyond a reasonable doubt that the
    criminal activity occurred, that juror may consider that activity as a fact in
    aggravation. If not so convinced, that juror must not consider that evidence for
    any purpose.”
    88
    3. Instruction Regarding Punishment of Accomplice
    Defendant contends the trial court erred by failing to instruct the jury to
    consider as a mitigating circumstance the punishment meted out to his accomplice,
    Gary Green. As defendant acknowledges, we have repeatedly rejected the claim
    that a court should instruct the jury that it may consider lenient treatment of an
    accomplice as a mitigating circumstance. “ „We have consistently held that
    evidence of an accomplice‟s sentence is irrelevant at the penalty phase because “it
    does not shed any light on the circumstances of the offense or the defendant‟s
    character, background, history or mental condition.” ‟ ” (People v. 
    Brown, supra
    ,
    31 Cal.4th at p. 562; accord, People v. Whalen (2013) 
    56 Cal. 4th 1
    , 85.)
    Similarly, we have rejected calls to reexamine our conclusion in light of Parker v.
    Dugger (1991) 
    498 U.S. 308
    , which defendant also cites. (People v. 
    Cain, supra
    ,
    10 Cal.4th at p. 63 [“Parker did not hold evidence of an accomplice‟s sentence
    must be introduced in mitigation at the penalty phase, or that a comparison
    between sentences given codefendants is required”].) We adhere to these
    conclusions.
    4. Use of Restrictive Adjectives and Restrictive Timeframe in
    Instructions on Mitigating Factors
    Defendant contends the use of certain restrictive adjectives in CALJIC
    No. 8.85 pertaining to mitigating factors, such as “extreme” and “substantial,”
    impose an unconstitutional threshold requirement before the jury may consider
    mitigating evidence. We have repeatedly rejected this argument (People v. Cage
    (2015) 
    62 Cal. 4th 256
    , 296), and do so again. We have also consistently rejected
    defendant‟s related claim that language in section 190.3, factors (d) and (h)
    allowing consideration of defendant‟s mental or emotional state or intoxication at
    the time of the offense precludes the jury from considering such evidence when it
    89
    is not related to the offense (People v. Combs (2004) 
    34 Cal. 4th 821
    , 867-868),
    and do so again.
    5. CALJIC No. 8.88
    Defendant makes familiar and oft-rejected challenges to CALJIC No. 8.88,
    which advises jurors regarding the scope of their discretion to reject death and
    return a verdict of life without the possibility of parole. We again conclude that
    the instruction is “not unconstitutional for failing to inform the jury that: (a) death
    must be the appropriate penalty, not just a warranted penalty [citation]; (b) [a
    sentence of life without the possibility of parole] is required, if it finds that the
    mitigating circumstances outweigh those in aggravation [citation] or that the
    aggravating circumstances do not outweigh those in mitigation [citation]; (c) [a
    sentence of life without the possibility of parole] may be imposed even if the
    aggravating circumstances outweigh those in mitigation [citation]; (d) neither
    party bears the burden of persuasion on the penalty determination [citation]. [¶]
    [Moreover,] section 190.3 and the pattern instructions are not constitutionally
    defective for failing to assign the state the burden of proving beyond a reasonable
    doubt that an aggravating factor exists, that the aggravating factors outweigh the
    mitigating factors, and that death is the appropriate penalty. . . . The recent
    decisions of the United States Supreme Court interpreting the Sixth Amendment‟s
    jury trial guarantee do not compel a different result.” (People v. Bramit (2009) 
    46 Cal. 4th 1221
    , 1249-1250, fn. omitted.) Finally, the use of the phrase “ „ “so
    substantial” ‟ ” as a standard of comparison for mitigating and aggravating factors
    does not render the instruction unconstitutional. (People v. Dykes (2009) 
    46 Cal. 4th 731
    , 814.)
    90
    G. Constitutional Challenges to Death Penalty Statute
    Defendant raises a number of challenges to the constitutionality of the
    death penalty statute, which, as he acknowledges, we have previously and
    consistently rejected. His arguments fail to persuade us to reconsider our prior
    decisions and, therefore, we again reject the contentions that the statute is
    unconstitutional because it (1) fails to require the jury to find the existence of
    aggravating factors beyond a reasonable doubt (People v. 
    Cage, supra
    , 62 Cal.4th
    at p. 296); (2) does not require written findings of factors in aggravation (ibid.);
    (3) does not require that the jury be instructed that mitigating factors can be
    considered solely for mitigation (ibid.); (4) does not require intercase
    proportionality review (People v. Charles (2015) 
    61 Cal. 4th 308
    , 337); and (5)
    provides certain procedural safeguards to noncapital defendants that are not
    available to capital defendants (ibid.).
    H. Denial of Automatic Motion to Modify Death Verdict
    Defendant contends the trial court erred when it denied his automatic
    motion to modify the death verdict (§ 190.4, subd. (e)) because it gave no weight
    to the mitigating evidence of duress, and it erroneously found that evidence of his
    mental health problems was not mitigating. He asserts the error violated his
    federal and state constitutional rights to due process and a reliable penalty
    determination, and the prohibition against arbitrary and capricious imposition of
    the death penalty. (U.S. Const., 5th, 8th & 14th Amends.; Cal. Const., art I, §§ 7,
    subd. (a), 15, 17.) Defendant failed to object to the trial court‟s ruling and his
    claim is therefore forfeited. (People v. 
    Carasi, supra
    , 44 Cal.4th at p. 1316.) It is
    also meritless.
    “Every death verdict triggers an automatic application for modification of
    the sentence. [Citation.] The trial court is obligated to review the evidence,
    independently reweigh any aggravating and mitigating circumstances, and
    91
    determine whether the weight of the evidence supports the verdict. [Citations.] In
    ruling on the application, the trial court must set forth reasons on the record and
    direct that they be entered in the clerk‟s minutes. [Citation.] On appeal, we
    review the trial court‟s ruling independently, but it is not our role to redetermine
    the penalty in the first instance.” (People v. 
    Gamache, supra
    , 48 Cal.4th at p.
    403.) “Where the record shows the trial court properly performed its duty under
    section 190.4, subdivision (e), to conduct an independent reweighing of the
    aggravating and mitigating evidence, the court‟s ruling will be upheld.” (People v.
    Cunningham (2015) 
    61 Cal. 4th 609
    , 669.)
    Here, the trial court‟s written statement of reasons for denying the motion
    demonstrates it was aware of its obligation to independently consider all the
    evidence. The court noted, however, that it was not the court‟s intention to “list
    every item of evidence . . . , but rather to recite the principal factors, which most
    powerfully inform and influence the decision at hand.” This was proper; the court
    was not required to “recount „every detail‟ supporting its determination.” (People
    v. Lewis and Oliver (2006) 
    39 Cal. 4th 970
    , 1064.)
    The trial court considered both aggravating and mitigating evidence. With
    respect to the factors in aggravation, the court found that the murder was willful,
    deliberate, and premeditated, with express malice aforethought, and was gang
    related. The court also listed, in some detail, defendant‟s long and violent history
    of other criminal activity while incarcerated. The court found there was no
    evidence to show defendant committed the murder under the influence of extreme
    mental or emotional disturbance or that he acted under extreme duress or the
    substantial domination of another. With respect to factors that might extenuate the
    gravity of the crime (§ 190.3, factor (k)), the court noted defendant‟s traumatic
    childhood, physical, mental and sexual abuse, his diagnosis of bipolar disorder,
    and the failure of prison authorities to consistently provide him with medication.
    92
    Nonetheless, the court concluded: “While it is easy to feel great sympathy for the
    defendant as a child, and it appears clear that the defendant should have received
    better mental health supervision in prison, it also appears that these factors had
    little to do with his decision to kill.”
    Although defendant frames his claim as a failure of the trial court to
    consider his mitigating evidence, his claim, in essence, is that the trial court failed
    to give sufficient weight to evidence of duress and his mental health issues. His
    contention does not reflect a valid appellate challenge to the trial court‟s decision.
    (See People v. Abilez (2007) 
    41 Cal. 4th 472
    , 530 [The fact that the trial court “did
    not find defendant‟s proffered mitigating evidence as persuasive as he would have
    liked does not undermine” the conclusion that the court properly conducted an
    independent reweighing of the aggravating and mitigating evidence].)
    Accordingly, even were the claim not forfeited by defendant‟s failure to object, we
    would affirm the trial court‟s ruling.
    I. International Law
    Contrary to defendant‟s assertion, “California‟s death penalty law does not
    violate international law and norms or evolving standards of decency.” (People v.
    
    Cage, supra
    , 62 Cal.4th at p. 297.)
    J. Disproportionality of the Death Sentence
    Defendant contends his death sentence is unconstitutionally
    disproportionate to the offense and the offender. “[W]hen a defendant requests
    intracase proportionality review, . . . we review the particular facts of the case to
    determine whether the death sentence is so disproportionate to the defendant‟s
    personal culpability as to violate the California Constitution‟s prohibition against
    cruel or unusual punishment.” (People v. 
    Wallace, supra
    , 44 Cal.4th at p. 1099.)
    93
    “ „To determine whether a sentence is cruel or unusual as applied to a
    particular defendant, a reviewing court must examine the circumstances of the
    offense, including its motive, the extent of the defendant‟s involvement in the
    crime, the manner in which the crime was committed, and the consequences of the
    defendant‟s acts. The court must also consider the personal characteristics of the
    defendant, including age, prior criminality, and mental capabilities. [Citation.]‟
    [Citation.] „If the court concludes that the penalty imposed is “grossly
    disproportionate to the defendant‟s individual culpability” [citation], or, stated
    another way, that the punishment “ „ “shocks the conscience and offends
    fundamental notions of human dignity” ‟ ” [citation], the court must invalidate the
    sentence as unconstitutional.‟ ” (People v. Virgil (2011) 
    51 Cal. 4th 1210
    , 1287.)
    Defendant‟s disproportionality argument emphasizes evidence that (1) he
    was manipulated and ordered to kill Addis, (2) prison authorities failed to provide
    consistent treatment for his bipolar disorder, and (3) he suffered a traumatic
    childhood. The only evidence he cites to support his claim of manipulation is
    expert testimony that he was easily manipulated; there is no evidence he was
    manipulated in this case. With respect to his claim that he was ordered to kill
    Addis, the fact that another gang member may have been the shot-caller does not
    mitigate defendant‟s culpability in this case. After defendant savagely attacked
    Addis, defendant lay giggling and laughing on the ground. In a subsequent letter,
    defendant wrote that the killing “kinda put me at ease, had to earn it,” and that
    committing the murder would elevate his status with higher ranking gang
    members. Based on this evidence, it appears he was a hit man for the gang rather
    than a pawn. In support of his theory of manipulation and duress, defendant
    asserts that prison officials knew Addis would be assaulted if he came into the
    yard, and he observes that he was not the person who demanded that Addis be
    94
    brought out, but he does not explain how these facts would diminish his role in the
    murder.
    With respect to treatment for defendant‟s bipolar disorder, although it is
    true there was evidence prison officials did not consistently provide defendant
    with certain psychotropic medications, it is also true, as the People point out, that
    there was evidence both that defendant denied he had any mental health issues and
    sometimes refused such medications. Thus, defendant‟s assertion that his criminal
    activity in prison merely “resulted from the denial of treatment for long-standing
    mental health issues” is not persuasive.
    Finally, with respect to defendant‟s traumatic childhood, although his
    childhood was characterized by abuse and neglect, there was also considerable
    family support offered to him by his grandparents.
    The evidence reflects that defendant, a member of a prison gang, with a
    long history of violence while incarcerated, committed a vicious, unwarranted,
    surprise attack on an unarmed fellow inmate, causing his victim to bleed to death.
    Considered together with defendant‟s personal circumstances, we cannot conclude
    that the imposition of the death penalty shocks the conscience or offends
    fundamental notions of human dignity.
    Defendant also invokes sections 1181, subdivision 7, and 1260 as authority
    for this court to reduce his sentence from death to life imprisonment without the
    possibility of parole.21 “But under those sections, „we lack the power to overturn
    21     Section 1181, subdivision 7, states that a court may grant a new trial motion
    “[w]hen the verdict or finding is contrary to law or evidence, but in any case
    wherein authority is vested by statute in the trial court or jury to recommend or
    determine as a part of its verdict or finding the punishment to be imposed, the
    court may modify such verdict or finding by imposing the lesser punishment
    without granting or ordering a new trial, and this power shall extend to any court
    to which the case may be appealed.”
    (footnote continued on next page)
    95
    a judgment of death simply because we disagree with the jury‟s penalty
    determination‟ [citation], and we may only reverse the judgment if we find
    „prejudicial error or legal insufficiency of evidence [citation].‟ ” (People v.
    Leonard (2007) 
    40 Cal. 4th 1370
    , 1427.) We find neither of those circumstances.
    K. Asserted Cumulative Error
    Defendant contends the cumulative weight of asserted errors occurring at
    his trial requires reversal. We have not affirmatively concluded that any errors
    occurred, and in those instances in which we have assumed an error, have
    concluded any error was harmless. Even when considered cumulatively, the
    assumed errors could not have deprived defendant of a fundamentally fair trial.
    IV. NONCAPITAL SENTENCING CLAIM
    Defendant contends the trial court erroneously imposed a one-year sentence
    enhancement for use of a deadly weapon (former § 12022, subd. (b)(1)
    (hereinafter section 12022(b)(1)) on count 3, the assault on Joseph Matthews
    (§ 4500) because use of a deadly weapon was an element of defendant‟s offense.
    We agree.22
    (footnote continued from previous page)
    Section 1260 provides that “[t]he court may reverse, affirm, or modify a
    judgment or order appealed from, or reduce the degree of the offense or attempted
    offense or the punishment imposed, and may set aside, affirm, or modify any or all
    of the proceedings subsequent to, or dependent upon, such judgment or order, and
    may, if proper, order a new trial and may, if proper, remand the cause to the trial
    court for such further proceedings as may be just under the circumstances.”
    22     Defendant did not object to the imposition of the enhancement at trial, but
    argues that the trial court‟s action constituted an unauthorized sentence that is
    subject to correction at any time without objection. (See People v. Cunningham
    (2001) 
    25 Cal. 4th 926
    , 1044.) On that basis, we review the claim.
    96
    At the time of trial, section 12022(b)(1) stated: “Any person who
    personally uses a deadly or dangerous weapon in the commission or attempted
    commission of a felony shall, upon conviction of that felony or attempted felony,
    in addition and consecutive to the punishment prescribed for the felony or
    attempted felony of which he or she has been convicted, be punished by an
    additional term of one year, unless use of a deadly or dangerous weapon is an
    element of the offense of which he or she was convicted.” (Italics added.) As a
    general rule, “[t]he phrase „element of the offense‟ signifies an essential
    component of the legal definition of the crime, considered in the abstract.”
    (People v. Hansen (1994) 
    9 Cal. 4th 300
    , 317, italics omitted, overruled on another
    ground in People v. Chun (2009) 
    45 Cal. 4th 1172
    , 1199.) In Hansen, the
    defendant was convicted of second degree felony murder, based on the underlying
    felony of discharging a firearm into an inhabited dwelling. We concluded the
    firearm use enhancement could be imposed on the defendant‟s conviction, because
    the crime of second degree murder, “considered in the abstract, does not include
    use of a firearm as an element. Second degree murder may be committed in a
    myriad of ways, some that involve use of a firearm, and others, such as stabbing,
    poisoning or strangling, that do not involve use of this type of weapon. Under
    [former] section 12022.5, subdivision (a), the enhancement applies unless „use of a
    firearm is an element of the offense,‟ and not merely the means by which the
    offense was committed or the factual predicate of a theory upon which the
    conviction was based.” (Hansen, at p. 317.)
    Defendant acknowledges Hansen, but contends the facts of this case come
    within the reasoning of People v. McGee (1993) 
    15 Cal. App. 4th 107
    (McGee).
    McGee stabbed his victim with a knife, and was convicted under former section
    245, subdivision (a)(1) (section 245(a)(1)), which applied to “ „an assault . . . [1]
    with a deadly weapon or instrument other than a firearm or [2] by any means of
    97
    force likely to produce great bodily injury . . . .‟ ” (McGee, at p. 112, fn. 2) The
    trial court imposed an enhancement under section 12022(b)(1) for use of a deadly
    weapon, which the Court of Appeal struck.
    The appellate court in McGee acknowledged that the phrase “ „element of
    the offense‟ ” in the enhancement statute means “ „an essential component of the
    legal definition of the crime considered in the abstract.‟ ” 
    (McGee, supra
    , 15
    Cal.App.4th at p. 114, italics omitted.) It also observed that section 245(a)(1)
    specified two forms of prohibited conduct, assault with a deadly weapon other
    than a firearm and assault by means of force likely to produce great injury.
    Therefore, section 245(a)(1) could be violated without using a deadly weapon.
    (Ibid.) The court further observed, however, that the statute “ „defines only one
    offense, to wit “assault upon the person of another with a deadly weapon or
    instrument [other than a firearm] or by any means of force likely to produce great
    bodily injury . . . .” The offense of assault by means of force likely to produce
    great bodily injury is not an offense separate from . . . the offense of assault with a
    deadly weapon.‟ [Citation.] Consequently, in determining whether use of a
    deadly weapon other than a firearm is an element of a section 245, subdivision
    (a)(1) conviction, the question is not simply whether, in the abstract, the section
    can be violated without using such a weapon. Rather, the conduct of the accused,
    i.e., the means by which he or she violated the statute, must be considered.”
    
    (McGee, supra
    , 15 Cal.App.4th at pp. 114-115.)
    Applying these observations to the facts before it, the court in McGee
    concluded: “Here, defendant‟s use of a deadly weapon other than a firearm was
    the sole means by which he violated section 245, subdivision (a)(1). The assault
    by means of force likely to produce great bodily injury was defendant‟s stabbing
    of the victim with a knife. Hence, his use of the weapon was an element of the
    offense, within the meaning of section 12022, subdivision (b), even though the
    98
    crime was pleaded as an assault by means of force likely to produce great bodily
    injury rather than as an assault with a deadly weapon other than a firearm.”
    
    (McGee, supra
    , 15 Cal.App.4th at p. 115.) The court also noted that the
    prosecutor had pleaded the offense as an assault by means of force likely to
    produce great bodily injury rather than an assault with a deadly weapon to “evade
    the statute‟s exception and to increase the punishment imposed on defendant.”
    (Id. at p. 116.) If prosecutors were allowed to “divide section 245, subdivision
    (a)(1) into two separate offenses regardless of the defendant‟s conduct, . . .
    similarly situated defendants who assaulted their victims with deadly weapons
    other than firearms and were charged with violating section 245, subdivision (a)(1)
    could receive disparate punishment depending solely upon the language used in
    the pleadings. . . . This is an absurd and unjust result which is inconsistent with
    the legislative intent in enacting sections 245, subdivision (a)(1) and 12022,
    subdivision (b).” (Id. at p. 117.)
    Section 4500 is similar to the version of section 245 considered in 
    McGee, supra
    , 
    5 Cal. App. 4th 107
    , in that section 4500 refers to a person “who, with
    malice aforethought, commits an assault upon the person of another with a deadly
    weapon or instrument, or by any means of force likely to produce great bodily
    injury.” (Italics added.) Thus, as was true of former section 245, subdivision
    (a)(1), section 4500 defines a single offense that can be committed in one of two
    ways, by use of a deadly weapon or instrument or by any means of force likely to
    produce great bodily injury. Whether in a particular case, the use of a deadly
    weapon or instrument was an element of the offense cannot be answered in the
    abstract; “the conduct of the accused, i.e., the means by which he or she violated
    the statute, must be considered.” 
    (McGee, supra
    , 15 Cal.App.4th at p. 115.)
    In this case, not only did the evidence show defendant used a razor to cut a
    gash in Matthews‟s back, but with respect to count 3, the jury was specifically
    99
    instructed: “In order to prove this crime, each of the following elements must be
    proved: (1) A person was assaulted; [¶] (2) The assault was committed with a
    deadly weapon or instrument . . . .” Thus, in the particular circumstances of this
    case, the use of a deadly or dangerous weapon was an element of defendant‟s
    offense under section 4500, barring imposition of the use enhancement set forth in
    section 12022 (b)(1).
    The People‟s attempts to distinguish McGee are unpersuasive. The People
    contend that McGee contradicts the public policy of punishing more severely those
    with a greater degree of culpability. The case they cite for this proposition, People
    v. Murray (1994) 
    23 Cal. App. 4th 1783
    , involved consecutive sentencing for mixed
    felony and misdemeanor convictions and not the enhancement at issue here; its
    public policy observation arises in that specific, and distinguishable, context. (Id.
    at pp. 1787-1788.) Moreover, the public policy considerations that underlie
    section 12022(b) were discussed at length in McGee, which examined the
    Legislature‟s intent in enacting the enhancement. McGee concluded that where
    “ „the Legislature has fixed the punishment for an assault where a deadly weapon
    is used, . . . it is not to be supposed that for the same offense without any
    additional factor existing the added punishment should be imposed.‟ ” 
    (McGee, supra
    , 15 Cal.App.4th at p. 116, quoting In re Shull (1944) 
    23 Cal. 2d 745
    , 751.)
    This observation applies with equal force to section 4500.
    The People also argue that McGee has been limited to the specific facts of
    that case, citing a footnote in People v. Ross (1994) 
    28 Cal. App. 4th 1151
    . In Ross,
    the trial court stayed imposition of a firearm use enhancement (former § 12022.5,
    subd. (b)), where defendant had been convicted of voluntary manslaughter by
    shooting the victim. The trial court reasoned that the use of the firearm was
    identical to the “ „crime itself‟ ” and thus section 654 precluded defendant from
    being punished twice for the same act. (Ross, at p. 1155.) The Court of Appeal
    100
    reversed because firearm use was not an element of voluntary manslaughter. In
    this connection, it distinguished McGee, noting that the statute at issue there,
    assault with a deadly weapon (§ 245(a)(1)), “had two alternative forms, as to one
    of which weapons use was an element,” and for that reason “has no application to
    this case.” (Ross, at p. 1156, fn. 7.) As noted above, section 4500 is analogous to
    section 245(a)(1), and, therefore, McGee’s reasoning is equally applicable.
    Accordingly, we strike the enhancement for use of a dangerous or deadly
    weapon from count 3.
    V. CONCLUSION
    The enhancement for use of a dangerous or deadly weapon is stricken from
    count 3, and the judgment is otherwise affirmed.
