    KAFKER, J.     A jury convicted the defendant, Patrick Waweru,
    of murder in the first degree on the theories of premeditation
    and extreme atrocity or cruelty, among other offenses.      The
    defendant's primary defense at trial was that he lacked criminal
    responsibility for the murder because he suffers from mental
    illness.   On appeal, the defendant argues error as to (1) the
    motion judge's denial of his motion to suppress statements made
    to a psychiatrist who interviewed him in the presence of police
    officers guarding him at the hospital; (2) the jury instructions
    regarding the presumption of sanity, the consequences of finding
    the defendant not guilty by reason of insanity, the failure to
    take prescribed medications, and reasonable doubt; and (3) the
    denial of his request for a jury-waived trial.    For the reasons
    stated below, we affirm.    After a thorough review of the record,
    we also decline to exercise our authority under G. L. c. 278,
    § 33E.
    1.     Background.   We summarize the facts that the jury could
    have found at trial, reserving certain details for our
    discussion of the legal issues.
    The defendant was in an on-again, off-again relationship
    with the victim.    The couple had two children together.   The
    victim's sister occasionally lived with the victim and the
    defendant, but the sister did not get along with the defendant.
    3
    The victim's mother also lived with the victim and the defendant
    for a time.
    The defendant has a history of mental illness.    In 2002, he
    was diagnosed with bipolar disorder II and a personality
    disorder with impulsive features.   He received outpatient
    medical health care.   In 2005, he was hospitalized for taking an
    overdose of his prescribed psychiatric medications.    He reported
    feeling that he was being "mistreated by his girlfriend and the
    legal system."   During his hospitalization, the defendant was
    diagnosed with a major depressive disorder, but the hospital
    clinicians did not find sufficient evidence to substantiate a
    bipolar disorder II diagnosis.   In early 2007, he was
    hospitalized and again diagnosed with bipolar disorder.1     He was
    prescribed mood stabilizing medication, Depakote; an
    antipsychotic medication, Risperdal; and an antidepressant.
    During this hospitalization, he threatened to kill the victim.
    At the time of his arrest, the defendant was working two
    jobs, one as a residential counsellor for a mental health
    facility, and the other at a nursing home.   The victim's sister
    testified that when the defendant and the victim were fighting,
    the defendant would periodically say that "even if he killed
    [the victim's sister] or [the victim], nothing would happen to
    1 The hospital diagnosis was not specific as to whether this
    was bipolar disorder I or bipolar disorder II.
    4
    him because . . . he was bipolar."
    In early 2007, the defendant moved out of the apartment he
    shared with the victim.   Around this time, he told the victim's
    mother, "When you get to Kenya, be prepared to receive two
    coffins, because I'm going to kill these daughters of yours.
    And I'm starting with [the victim's sister].     [She] will not
    raise my children.   Instead, they'll be raised by the [S]tate."
    Later the same year, the victim, her children, and her mother
    moved to Delaware, primarily to get away from the defendant.
    The victim's sister remained in Massachusetts.
    On the weekend of October 14, 2007, the victim, her
    daughters, and her mother returned to Massachusetts, ostensibly
    for a Housing Court appearance related to the apartment the
    defendant and the victim had previously shared.2    During their
    visit, they stayed in the victim's sister's one-bedroom
    apartment in Lynn.
    The victim left her sister's apartment in the early morning
    on October 15.   She and the defendant spent the day running
    errands.   Later that day, the victim and the defendant drove
    back to her sister's apartment.   The victim called her sister
    2 No actual court appearance had been scheduled. The
    defendant indicated to the defense's expert witness, a forensic
    psychologist, that he intended to "speak with a clerk about
    reassessing the decision that had been made by the Housing Court
    sometime earlier." The Commonwealth has characterized this as a
    "ruse" to lure the victim back to Massachusetts.
    5
    from outside, at approximately 9:27 P.M.     Her sister told her to
    come inside.     When the victim entered the apartment a few
    minutes later, she locked the door behind her.     The victim's
    sister observed that the victim appeared "somewhat calm, but
    nervous at the same time."     The victim sat with the rest of her
    family in the living room and spoke with them, while the
    defendant continued to wait outside.
    Approximately one-half hour after the victim arrived, the
    defendant appeared at the front door to the apartment and
    shouted through the door that he wanted his cellular telephone
    (cell phone) back.3    When the victim's mother heard the
    defendant's voice, she quickly placed a chair against the door
    and sat on it.    The victim's sister told the defendant that he
    would get his cell phone back.     She called each of her neighbors
    in the building to help facilitate a transfer of the cell phone,
    but no one answered.     The defendant asked for his cell phone a
    second time, and the victim's sister again responded that he
    would get his cell phone back.     The victim's mother told the
    victim and her sister that they should call the police.        At some
    point, the victim's mother moved the chair away from the door.
    Not long after, the defendant broke through the door with a two-

    victim may have had the defendant's cellular telephone.
    6
    by-four piece of lumber taken from outside the apartment.4       The
    victim's mother testified that the defendant said something to
    her, but she could not understand him.     The defendant
    immediately hit the victim's sister over the head with the piece
    of lumber.   He then grabbed the sister by the collar, but she
    managed to pull away.    She staggered out of the apartment and
    went upstairs, screaming for help.    The victim's four year old
    daughter followed her.
    The defendant hit the victim over the head with the same
    piece of lumber he had used to hit her sister.    The victim fell
    to the ground and was seemingly knocked unconscious.       The
    defendant took out a knife that he had hidden in his sock.       The
    victim's mother attempted to grab the knife, but cut herself
    when the defendant pulled away.     The defendant bent down and
    stabbed the victim twenty-four times in the back, the chest, the
    head, the neck, and the left arm.    During the attack, their one
    year old daughter was crawling between the defendant, the
    victim, and the victim's mother.    After stabbing the victim, the
    defendant fled the scene and disposed of the murder weapon in a
    cemetery.
    The victim's sister was able to reach one of her neighbors,
    4 The landlord had placed two-by-four pieces of lumber just
    outside the front door of the victim's sister's apartment in
    order to make repairs.
    7
    who telephoned the police.   The victim was still alive when the
    police arrived, but died shortly thereafter.   The defendant was
    subsequently arrested at his apartment.   The arresting officers
    observed that the defendant appeared to be "under the influence
    of something."   The defendant told the officers that he had
    "[taken] some pills."   He was admitted to Union Hospital for
    treatment of a suicide attempt.   The defendant was placed in the
    intensive care unit under police guard.   A psychiatrist at the
    hospital, Dr. Maureen McGovern, performed a suicide risk
    evaluation on the defendant.   He could not remember the night of
    the murder, but told the doctor that the victim "was the cause
    of all his problems" and that "he had thoughts about hurting
    her."5
    At trial, the defendant did not contest that he killed the
    victim, but argued that he lacked criminal responsibility at the
    time of the murder.   Defense counsel called an expert witness, a
    forensic psychologist, who had performed a psychological
    evaluation of the defendant.   The expert diagnosed the defendant
    with bipolar disorder II, with "mixed characteristics of
    5 Dr. Maureen McGovern testified that the defendant said he
    had thoughts about "hurting" the victim. One of the police
    officers on guard in the defendant's hospital room testified
    that he overheard the defendant say he had thoughts about
    "killing" the victim.
    8
    depression and hypomania."6    The hypomania was exhibited by
    "restlessness" and "agitation," and the depression was exhibited
    by "subjective reports of depression . . . [and] difficulty
    sleeping."
    The defense's expert witness testified that the defendant
    had been depressed, in part because he felt that the victim was
    keeping him from seeing their children.    The defendant indicated
    to the expert that he was having trouble sleeping in the days
    leading up to the murder.     He had also stopped taking his mood
    stabilizing medication because "he had been feeling good."
    The expert testified that the defendant indicated his
    "spirits went up" on the day of the murder because the victim
    had indicated a willingness to stay with him for a period of
    time to "help to extricate him from the depression that he was
    experiencing."   This tentative plan would involve the victim
    going back to Delaware, gathering a few items for herself and
    the children, and returning to stay with the defendant.
    The defense expert testified that, on the night of the
    murder, after waiting for the victim outside her sister's
    apartment for approximately ten to twenty minutes, the defendant
    6 The defense's expert witness defined hypomania as being a
    state with many of the same symptoms as mania, but lasting a
    shorter duration. These symptoms include "a heightened sense of
    self-esteem, a lessened sense of the need for sleep,
    changeability in mood states, [and] agitation."
    9
    began thinking she was not coming back.   The defendant believed
    the victim's sister and mother would not allow him to go to
    Delaware with the victim.   He indicated to the psychologist that
    "his intent was to go down [to the sister's apartment] and get
    [the victim] so they could be on their way to Delaware."
    The defendant explained to the psychologist that he was
    carrying a knife in his sock in order to kill himself.     He could
    not recall what happened after he reached the front door of the
    sister's apartment.   Given the defendant's inability to recall
    the murder itself, the defense expert was unable to reach a
    definitive conclusion as to whether the defendant lacked
    criminal responsibility at the time of the murder.   However, the
    expert testified that "[the defendant's] behaviors are
    consistent with an inability to conform his behavior to the
    requirements of the law."
    The Commonwealth called its own expert witness on rebuttal,
    a forensic psychiatrist, who testified that he was not convinced
    that the defendant was bipolar, and did not believe that the
    defendant had a mental disease or defect at the time of the
    murder.   The Commonwealth's expert further stated, "There's
    nothing that, in my opinion, . . . resulted in the lack of
    substantial capacity to conform [the defendant's] conduct to
    requirements of the law."   He also indicated that individuals
    with bipolar disorder usually "don't have a pattern of violence
    10
    directed at others."
    A jury convicted the defendant of murder in the first
    degree, home invasion, armed assault with intent to murder,
    assault and battery of the victim's sister by means of a
    dangerous weapon, and wanton and reckless endangerment of a
    child.    He was acquitted of assault and battery of the victim's
    mother by means of a dangerous weapon.
    2.    Discussion.   a.   Admission of statement to
    psychiatrist.   Prior to trial, the defendant sought to suppress
    statements he made to a psychiatrist after the murder.         His
    motion to suppress was denied.    On appeal, the defendant argues
    that the motion judge erred in denying his motion because the
    statements were (1) involuntary; (2) protected by the
    psychotherapist-patient privilege; and (3) obtained in violation
    of his due process rights.    We address each argument in turn.
    We summarize the motion judge's factual findings,
    supplemented by testimony from the hearing that was credited by
    the motion judge.    See Commonwealth v. Walker, 
    466 Mass. 268
    ,
    270 (2013).   See also Commonwealth v. Jones-Pannell, 
    472 Mass. 429
    , 431 (2015).    On the night of the victim's murder, police
    went to the defendant's residence.    Officers knocked on the
    defendant's apartment door and heard a large crash.      The
    officers knocked on the door again and asked, "Are you all
    right?"   The defendant answered "I can't walk."    Officers heard
    11
    what sounded like someone falling, and entered the residence to
    find the defendant holding the door.    The defendant confirmed
    his identity to the officers.    He was on the floor with his legs
    tucked under him.    The motion judge found that the defendant
    "appeared intoxicated and had blood on his jean pants."       The
    officers placed the defendant in custody.    They asked the
    defendant if he had taken drugs, and he responded affirmatively.
    There were drugs and packets of Clonazepam in the area around
    the defendant.
    The defendant was taken to Union Hospital.     He appeared to
    be conscious but under the influence.    He was placed in a single
    room in the intensive care unit and shackled to a hospital bed.
    The defendant's toxicity screens came back negative, but he had
    to be intubated because he was "lethargic to the point that he
    could not protect his own airways."
    Two officers arrived at the hospital to secure the
    defendant and keep him under observation.    When they arrived,
    the defendant was lying down while somewhat propped up in the
    hospital bed.    The officers noticed that the defendant's eyes
    were closed at times.    They sat in chairs located inside the
    room, "past where the defendant was occupying the bed."       Various
    hospital personnel visited the defendant, and the defendant was
    able to respond appropriately to their questions.    At no point
    did the officers give the defendant Miranda warnings.
    12
    The physician who admitted the defendant asked an attending
    psychiatrist at the hospital, McGovern, to do a psychological
    consultation on the defendant.    McGovern spoke with the
    defendant more than twelve hours after his arrest and in the
    presence of the police officers.    During this conversation,
    McGovern was located on one side of the bed and the officers
    were seated on the other.    The officers did not, however, engage
    McGovern or the defendant in conversation.
    McGovern asked the defendant medical questions, but did not
    give him Lamb warnings.7    See Commonwealth v. Lamb, 
    365 Mass. 265
    , 270 (1974).    His responses appeared to be appropriate to
    the questions asked.   The defendant did not slur his speech,
    appear injured, or complain of pain.    His vital signs were
    normal.   McGovern further observed that the defendant was quiet,
    subdued, calm, and cooperative.    She noted that the defendant
    had been medicated with a blood thinner and a medication to
    reduce stomach acidity.    Neither of these medications affected
    his mental state.   Although he appeared slightly drowsy, he was
    able to maintain attention throughout the thirty-minute
    interview with the psychiatrist.    McGovern believed that the
    7 In Commonwealth v. Lamb, 
    365 Mass. 265
    , 270 (1974), we
    held that when a psychotherapist conducts a court-ordered
    examination of a defendant, the psychotherapist must warn the
    defendant that the communications are not privileged. We note
    that McGovern was not conducting a court-ordered examination.
    See Commonwealth v. Seabrooks, 
    433 Mass. 439
    , 450-451 (2001).
    13
    defendant was "cognitively intact"8 and had a "thought process
    [that] appeared goal oriented."9    However, she was concerned
    about his emotional stability and worried that he might attempt
    suicide again.   She diagnosed him with depression, with elements
    of mania.
    During her evaluation, McGovern asked the defendant if he
    wished to harm himself or others.    He indicated that he wanted
    to harm himself, and stated, "Since Friday, I was thinking I
    wanted to kill my girlfriend because she's the cause of my
    problems."
    i.   Voluntariness.   First, the defendant argues that his
    statements to McGovern were not given voluntarily, because they
    were given as a result of the defendant's debilitated condition.
    We disagree.   The motion judge correctly found that the
    statements were voluntary.
    "An admission by a defendant to a civilian is only
    admissible if voluntarily made."    Commonwealth v. Anderson, 
    445 Mass. 195
    , 204 (2005).     See Commonwealth v. Kolenovic, 
    478 Mass. 189
    , 198 (2017).   An admission is voluntary if it was "the
    8 McGovern testified that "cognitively intact" means that
    the defendant did not appear to be delirious or demented.
    Rather, he appeared to understand where he was and "his general
    fund of knowledge was average."
    9 McGovern testified that "goal oriented" describes a
    thought process in which the patient understands the questions
    being asked of him or her and gives appropriate answers.
    14
    product of a 'rational intellect' and a 'free will,' and not
    induced by physical or psychological coercion."    Commonwealth v.
    Harris, 
    468 Mass. 429
    , 434-435 (2014), quoting Commonwealth v.
    LeBlanc, 
    433 Mass. 549
    , 554 (2001).     Courts evaluate
    voluntariness based on the totality of the circumstances.    See
    Harris, supra at 435.    See also Commonwealth v. Mello, 
    420 Mass. 375
    , 384 (1995).   "Statements that are attributable in large
    measure to a defendant's debilitated condition, such as insanity
    . . . drug abuse or withdrawal symptoms, . . . [or] intoxication
    . . . are not the product of a rational intellect or free will
    and are involuntary."    Commonwealth v. Allen, 
    395 Mass. 448
    , 455
    (1985).   See Commonwealth v. Bell, 
    473 Mass. 131
    , 141 (2015),
    cert. denied, 
    136 S. Ct. 2467
     (2016).
    Here, the motion judge found that the statements were made
    voluntarily because the defendant was "emotionally stable,
    cognitively intact, calm and cooperative, and not influenced by
    drugs or alcohol" during his conversation with McGovern.     There
    was ample evidence to support the motion judge's conclusion.
    The defendant's toxicity screen was negative, the conversation
    took place over twelve hours after the defendant was arrested,
    and his speech was not slurred.   Based on her conversation with
    the defendant, McGovern observed that he understood where he was
    and was able to understand the questions being asked of him and
    respond appropriately.   See Commonwealth v. Brown, 
    449 Mass. 15
    747, 767 (2007) (trial judge's finding that statement was
    voluntary was supported by testimony that defendant did not have
    trouble understanding questions his friends posed to him, and
    friends did not have trouble understanding his answers);
    LeBlanc, 433 Mass. at 555 ("Although the defendant was
    emotionally upset, he spoke calmly when giving his statement,
    and there is no evidence that he was acting irrationally").
    While McGovern noted that the defendant's "insight and judgment
    [were] poor," this was based on his suicide attempt, not his
    responses to her questions.
    Further, the defendant did not present any evidence
    indicating that his statements to McGovern were the result of
    threats, promises, or trickery.     See Commonwealth v. Allen, 
    395 Mass. 448
    , 456 (1985).   Nor were the police required to provide
    the defendant with Miranda warnings, as his statements were not
    made in response to a police interrogation and McGovern was not
    acting as an agent of the police.    See 
    id. 453-454
    .   See also
    Commonwealth v. Trigones, 
    397 Mass. 633
    , 643 (1986).
    Accordingly, we discern no error in the motion judge's
    determination that the defendant's statements were made
    voluntarily.10
    10Moreover, the trial judge gave the jury a humane practice
    instruction after the jury heard testimony about the defendant's
    statements to McGovern. The judge instructed the jury, in
    16
    ii.   Psychotherapist-patient privilege.    The defendant
    argues that his statements to McGovern were protected by the
    patient-psychotherapist privilege set forth in G. L. c. 233,
    § 20B.   The statute provides:   "[I]n any court proceeding
    . . . , a patient shall have the privilege of refusing to
    disclose, and of preventing a witness from disclosing, any
    communication, wherever made, between said patient and a
    psychotherapist relative to the diagnosis or treatment of the
    patient's mental or emotional condition."    The motion judge
    determined that because the defendant's statements were made in
    the presence of two police officers, the privilege did not
    attach or, to the extent it did, the defendant had waived it.
    We review for prejudicial error.   See Commonwealth v. Dung Van
    Tran, 
    463 Mass. 8
    , 16 (2012).    We conclude that the privilege
    did attach and was not waived by the presence of the police
    officers, but also that there was overwhelming evidence of the
    defendant's premeditation and any error in the admission of
    McGovern's testimony would not have been prejudicial.
    A.    Waiver.   Under G. L. c. 233, § 20B, the
    psychotherapist-patient privilege attaches to any communications
    relevant part, as follows: "[B]efore you can consider [the
    defendant's statement], the Commonwealth has to prove to you
    . . . beyond a reasonable doubt, that the defendant's statement
    was voluntarily made[,] that is, that it was made as a product
    of his own free will and rational intellect."
    17
    between a "patient and a psychotherapist relative to the
    diagnosis or treatment of the patient's mental or emotional
    condition."   In communicating with McGovern for the purpose of a
    suicide risk evaluation, the defendant met the statutory
    definition of "patient"11 under § 20B, and McGovern, as a
    licensed, practicing psychiatrist, met the statutory definition
    of "psychotherapist."12   The suicide risk evaluation was also
    specifically targeted at diagnosing and treating the defendant's
    "mental or emotional condition."   Id.   Thus, the defendant's
    communications with McGovern during the suicide risk evaluation
    met the statutory requirements for the psychotherapist-patient
    privilege to attach.13
    11Under G. L. c. 233, § 20B, "patient" is defined as "a
    person who, during the course of diagnosis or treatment,
    communicates with a psychotherapist."
    12Under G. L. c. 233, § 20B, "psychotherapist" is defined
    in relevant part as "a person licensed to practice medicine, who
    devotes a substantial portion of his time to the practice of
    psychiatry."
    13The motion judge indicated that the psychotherapist-
    patient privilege requires a "confidential relationship" before
    it can attach. Although our prior cases have discussed the
    requirement that a "confidential relationship" exist between the
    patient and the psychotherapist, this was specifically in
    reference to the issue whether the person to whom the statement
    was made meets the statutory definition of "psychotherapist."
    See Commonwealth v. Mandeville, 
    386 Mass. 393
    , 409-410 (1982).
    A confidential relationship exists, such that the
    psychotherapist-patient privilege applies, whenever the
    statutory requirements of G. L. c. 233, § 20B, are met. See
    Robinson v. Commonwealth, 
    399 Mass. 131
    , 135 (1987);
    18
    The Commonwealth contends that that the privilege was
    nonetheless waived because the communications between the
    defendant and McGovern were made in the presence of the police
    officers guarding the defendant in the hospital.   The statute
    contemplates that a patient may choose to waive the privilege.
    See G. L. c. 233, § 20B ("If a patient is incompetent to
    exercise or waive such privilege, a guardian shall be appointed
    to act in his behalf under this section" [emphasis added]).
    However, no explicit waiver occurred here.   Thus, we must
    determine whether the presence of police officers constituted a
    waiver, absent the patient's affirmative consent to waive the
    privilege.
    In interpreting the psychotherapist-patient privilege and
    the issue of waiver, we must look first to the text of the
    statute itself.   See Commonwealth v. Vega, 
    449 Mass. 227
    , 230
    (2007).   See also Usen v. Usen, 
    359 Mass. 453
    , 457 (1971) ("We
    are not free to water down the legislative policy embodied in
    [G. L. c. 233, § 20B,] by loose construction or by giving our
    approval to informal procedures different from those
    prescribed").   The plain language of G. L. c. 233, § 20B, does
    not waive or restrict the availability of the privilege based on
    the presence of others or the particular location.   To the
    Commonwealth v. Clemons, 
    12 Mass. App. Ct. 580
    , 584 n.2 (1981).
    See also Mandeville, 
    supra
     (adopting Clemons analysis).
    19
    contrary, the statute explicitly states that, "a patient shall
    have the privilege of refusing to disclose, and of preventing a
    witness from disclosing, any communication, wherever made,
    between said patient and a psychotherapist relative to the
    diagnosis or treatment of the patient's mental or emotional
    condition" (emphasis added).   
    Id.
       The language here is
    expansive, not restrictive, broadly protecting "the private
    interest that patients have in speaking freely during
    psychotherapy, and the public interest in encouraging troubled
    people to seek therapy."   Conklin v. Feitelberg, 
    146 F. Supp. 3d 430
    , 437 (D. Mass. 2015), quoting Vanderbilt v. Chilmark, 174
    F.R.D 225, 227 (D. Mass. 1997).
    Unlike many other States that require the communication to
    be confidential or not intended for further disclosure, the
    Commonwealth has no such requirement in the text of G. L.
    c. 233, § 20B.   Contrast 
    Ala. Code § 34-26-2
     (privilege applies
    to "confidential relations and communications"); 
    Fla. Stat. § 90.503
     (privilege applies to "confidential communications,"
    defined as those not intended to be disclosed to third parties,
    other than those expressly permitted in statute); 
    Or. Rev. Stat. § 40.230
     (same); 
    S.D. Codified Laws § 19-19-503
     (same).     Indeed,
    in Massachusetts the privilege applies to psychotherapist-
    patient communications, "regardless of the patient's awareness
    of such conversations, correspondence, actions and occurrences,
    20
    and any records, memoranda or notes of the foregoing."     G. L. c.
    233, § 20B.   See Robinson v. Commonwealth, 
    399 Mass. 131
    , 135
    (1987).
    The expansive scope of the privilege is limited by six
    specific exceptions defining when the privilege is waived and
    disclosure is permitted.   See G. L. c. 233, § 20B.   None of
    these exceptions turns on the presence of a third party.    We
    need not decide, however, whether the presence of a third party
    may still waive the privilege, as we conclude that the nature of
    the police presence here could not have done so.
    Here, the police presence served essential public safety
    purposes.   The defendant needed psychiatric services but also
    presented a grave danger to the public and hospital personnel.
    The police were deployed to guard the defendant and protect the
    public, including the hospital's medical personnel, and allow
    him to be treated despite those concerns.   Given their public
    safety responsibilities, the police should not be required to
    leave the defendant's hospital room to allow the defendant to
    speak with a psychotherapist alone.14   Nor should the
    psychotherapist be required to get so close to the defendant
    that only she and the defendant can hear one another.
    14This is true even if the defendant is shackled to the
    bed. The police and not the courts are in the best position to
    know whether the defendant remains dangerous even while
    shackled.
    21
    Psychotherapists should not be tasked with putting their own
    safety at risk in order to treat a dangerous patient.
    In the absence of legislative direction to the contrary, we
    therefore conclude that police presence during a psychiatric
    consultation, which allows the defendant to receive necessary
    medical attention while protecting the public and medical
    personnel, does not waive the psychotherapist-patient privilege.
    Rather, allowing such consultations to go forward under police
    supervision, while leaving the privilege in place unless other
    exceptions providing for disclosure apply, properly balances
    both medical and public safety considerations.   See State v.
    Deases, 
    518 N.W.2d 784
    , 788 (Iowa 1994) (doctor-patient
    privilege not waived by presence of third party if third party
    is present to assist doctor or presence is necessary to enable
    defendant to obtain treatment); People v. Sanders, 
    169 Misc. 2d 813
    , 819-820 (N.Y. Sup. Ct. 1996) (doctor-patient privilege not
    waived where police officer "was required to remain with the
    defendant at all times" and the defendant "did not have the
    option or ability to request a private session with the
    psychiatrist").   Cf. Secrest v. State, 
    679 A.2d 58
    , 62 (Del.
    1996) (third-party waiver "makes sense in situations where the
    patient is reasonably lucid and able to control access to the
    setting").   Accordingly, we hold that a patient who has been
    placed under police guard does not automatically waive the
    22
    psychotherapist-patient privilege by speaking to a
    psychotherapist in the presence of said police guard.15,16
    15Our holding is also in accordance with our case law on
    attorney-client privilege. Attorney-client privilege is
    generally undermined by the presence of a third party. See
    Commissioner of Revenue v. Comcast Corp., 
    453 Mass. 293
    , 306
    (2009). There is an exception to this general rule, however,
    when the presence of the third party is "necessary for the
    effective consultation between client and attorney" (quotations
    omitted). 
    Id. at 307
    , quoting United States v. Kovel, 
    296 F.2d 918
    , 922 (2d Cir. 1961). In order to be "necessary," the third-
    party presence must be "nearly indispensable or serve some
    specialized purpose in facilitating the attorney-client
    communications." Comcast Corp., supra. In such instances, the
    privilege still attaches. Id.
    16Although it was error to find that the defendant had
    waived the psychotherapist-patient privilege, we note that the
    statement may very well have been admissible under G. L. c. 233,
    § 20B (c). Subsection (c) provides that the psychotherapist-
    patient privilege will not apply
    "[i]n any proceeding, except one involving child custody,
    adoption or adoption consent, in which the patient
    introduces his mental or emotional condition as an element
    of his claim or defense, and the judge or presiding officer
    finds that it is more important to the interests of justice
    that the communication be disclosed than that the
    relationship between patient and psychotherapist be
    protected."
    The defendant "introduce[d] his mental or emotional condition as
    an element of his claim or defense" by arguing at trial that he
    was not criminally responsible. See Commonwealth v. Brandwein,
    
    435 Mass. 623
    , 630 n.8 (2002). The motion judge also could have
    found it "more important to the interests of justice" that the
    defendant's statements be admitted, particularly given that
    there was no ongoing patient-therapist relationship between the
    defendant and McGovern, and McGovern's evaluation was the only
    examination conducted around the time of the murder, rendering
    the evaluation important to the truth-seeking function of the
    court. See Commonwealth v. Seabrooks, 
    433 Mass. 439
    , 448-450
    (2001). The defendant's apparent inability to recall the murder
    23
    B.   Prejudice.     Although the presence of the police
    officers did not waive the psychotherapist-patient privilege, we
    conclude that any error in the admission of McGovern's testimony
    would not have prejudiced the defendant because the evidence of
    the defendant's premeditation and criminal responsibility was
    overwhelming.   Perhaps most significantly, the defendant had
    repeatedly stated that "even if he killed [the victim's sister]
    or [the victim], nothing would happen to him because . . . he
    was bipolar."   He also made his intentions clear to the victim's
    mother months before the murder, stating, "When you get to
    Kenya, be prepared to receive two coffins, because I'm going to
    kill these daughters of yours.    And I'm starting with [the
    victim's sister].     [She] will not raise my children.   Instead,
    they'll be raised by the [S]tate."
    On the night of the murder, he acted in conformance with
    this plan:   first attacking the victim's sister, and then
    attacking the victim.    Further, the defendant appeared to act
    normally up until the night of the killing, even running errands
    not only inhibited the jury's ability to evaluate his mental
    state but also interfered with defense counsel's own expert's
    ability to evaluate whether he lacked criminal responsibility.
    Insight into the defendant's mental state shortly after the
    crimes were committed would thus have been very helpful in
    evaluating his primary defense at trial. The trial judge,
    however, would have had to make findings and weigh all the
    factors set out in Seabrooks, supra at 449-450, including
    whether the defendant consulted with counsel before speaking to
    McGovern, which he did not.
    24
    with the victim.    See Commonwealth v. Griffin, 
    475 Mass. 848
    ,
    856-857 (2016).    There was also compelling evidence that the
    attack was planned.    He brought the murder weapon with him,
    hidden in his sock, to the victim's sister's apartment.      When he
    stabbed the victim in a very small, narrow space, he did so
    carefully enough to avoid injuring their one year old daughter,
    who was crawling between the defendant and the victim.
    Moreover, the defendant's own expert testified that the
    defendant "certainly understood the wrongfulness of the [murder]
    immediately after the events," because he fled the crime scene
    and disposed of the murder weapon.   Given the substantial
    evidence of premeditation and criminal responsibility, the
    admission of the defendant's statement to McGovern about wanting
    to kill his girl friend did not prejudice the defendant.
    iii.   Due process.    For the first time on appeal, the
    defendant argues that the admission of his statement to McGovern
    also violated his Federal and State due process rights because
    she did not provide him Lamb warnings indicating that the
    statement would not be confidential.    He cites two cases
    involving the Federal and State constitutional privileges
    against self-incrimination for this proposition.   "For the
    privileges [against self-incrimination] to attach, the State
    must compel the defendant to produce testimonial evidence."
    Commonwealth v. Seabrooks, 
    433 Mass. 439
    , 451 (2001).     As
    25
    previously discussed, the defendant's statement was voluntary
    and was not compelled.   Further, Lamb warnings were not
    required, as the psychotherapist's questioning was not court-
    ordered or for the purposes of producing evidence against him.
    See Lamb, 
    365 Mass. at 270
    .
    b.    Jury instructions.   The defendant argues that the trial
    judge, who was not the motion judge, erred in instructing the
    jury for four separate reasons.   For the reasons discussed
    below, none of these arguments is persuasive.
    i.    Inference of sanity.   On the issue of criminal
    responsibility, the trial judge in this case instructed the jury
    as follows:   "[The Commonwealth has] to prove that the defendant
    was sane; that is, was criminally responsible.    If you feel it
    appropriate you may take into account that the great majority of
    people are sane, and that there is a resulting likelihood that
    any particular person is sane."   This instruction was given
    pursuant to our then-current case law, see Commonwealth v.
    Keita, 
    429 Mass. 843
    , 846 (1999) ("A jury instruction concerning
    the presumption of sanity should be given in every case in which
    the question of the defendant's criminal responsibility is
    raised"), as well as the Model Jury Instructions on Homicide in
    effect at the time.   See Model Jury Instructions on Homicide 51
    (1999).   In Commonwealth v. Lawson, 
    475 Mass. 806
    , 814-815 & n.8
    (2016), we held that, "given the meager weight of [the inference
    26
    that a defendant is probably sane because most people are sane]
    and the risk of juror confusion regarding the burden of proof,
    judges should not instruct juries regarding this inference."
    "Here, the defendant is entitled to the benefit of Lawson,
    as that case was released while the defendant's appeal was
    pending on direct review."   Commonwealth v. Muller, 
    477 Mass. 415
    , 431 (2017).   As defense counsel objected to the sanity
    presumption at trial, even though Lawson had not yet been
    issued, we review for prejudicial error.   See Commonwealth v.
    Cole, 
    473 Mass. 317
    , 325 (2015).
    In this case, the trial judge "strongly and specifically
    instructed that the burden is on the Commonwealth to prove
    criminal responsibility beyond a reasonable doubt."17   Muller,
    17Regarding the burden of proof on criminal responsibility,
    the trial judge stated:
    "[A]s to all of these charges, the Commonwealth also has to
    prove to you that defendant did not lack criminal
    responsibility. Remember the burden of proof is always on
    the Commonwealth. The Commonwealth has to prove that the
    person committed the crime charged, and that he was at the
    time in such a mental state that he did not lack criminal
    responsibility. If you're satisfied beyond a reasonable
    doubt that the defendant committed the crime -- any of the
    crimes that I have defined for you, you must decide whether
    the Commonwealth has met an additional burden. The
    Commonwealth also must prove that the defendant was
    criminally responsible when he committed the crime
    charged. . . . The Commonwealth must prove that the
    defendant was criminally responsible beyond a reasonable
    doubt. The burden is not on the defendant to prove a lack
    of criminal responsibility. Instead, the burden is on the
    27
    477 Mass. at 431, quoting Commonwealth v. Griffin, 
    475 Mass. 848
    , 863 (2016).    Further, as discussed above, there was
    overwhelming evidence of criminal responsibility.    See Muller,
    supra, quoting Griffin, supra.    Thus, the defendant was not
    prejudiced by any such error due to the overwhelming evidence of
    criminal responsibility and the trial judge's detailed
    instructions on the burden of proof for criminal responsibility.
    See Griffin, supra.
    ii.    Consequences of not guilty verdict.   The trial judge
    instructed the jury on the consequences of finding the defendant
    not guilty by reason of insanity, as permitted by Commonwealth
    v. Mutina, 
    366 Mass. 810
    , 823 & n.12 (1975) (Mutina instruction)
    and our Model Jury Instructions on Homicide in effect at the
    time of trial.18   In Commonwealth v. Chappell, 
    473 Mass. 191
    ,
    Commonwealth to prove criminal responsibility beyond a
    reasonable doubt. Under the law, the Commonwealth bears
    the burden of proving beyond a reasonable doubt the
    defendant committed the crime or crimes with which he's
    charged, and also that the defendant is criminally
    responsible for his conduct."
    18   The trial judge instructed:
    "[I]n in the event that the defendant is found not guilty
    by lack of criminal responsibility . . . , the District
    Attorney . . . may petition . . . for his commitment . . .
    if in that proceeding the Commonwealth proves beyond a
    reasonable doubt that the defendant is mentally ill at the
    present time, and that his discharge would create a
    likelihood of serious harm to himself or others. . . .
    [T]he order of commitment is thereafter periodically
    28
    205-206 (2015), we held that, going forward, Mutina instructions
    should "omit[] references to specific time frames for
    observation and mention[] the potential for successive
    commitment orders that could span the duration of the
    defendant's life."   The defendant argues for the first time on
    appeal that the jury instructions created a substantial
    likelihood of a miscarriage of justice for failing to include
    the supplemental jury instructions from Chappell.
    We have previously stated that it is not error for a judge
    to have given the Mutina instruction when it was the governing
    model jury instruction at the time of trial.   See Commonwealth
    v. Dunn, 
    478 Mass. 125
    , 139 (2017).   This is because we held in
    Chappell, 473 Mass. at 205, that the trial judge in that case
    did not err in providing the Mutina instruction.    Rather, in
    Chappell, the Mutina instruction was changed prospectively to
    "better explain to the jury 'what protection they and their
    fellow citizens will have if they . . . arrive at a verdict of
    not guilty by reason of [lack of criminal responsibility].'"
    Dunn, supra, quoting Chappell, supra at 206.   Thus, because the
    trial here took place before our decision in Chappell, the
    instruction was proper and did not create a substantial
    reviewed[,] . . . [and] [i]f the Commonwealth fails to
    prove these matters beyond a reasonable doubt, the
    defendant is discharged."
    29
    likelihood of a miscarriage of justice.     See Commonwealth v.
    Piantedosi, 
    478 Mass. 536
    , 550 (2017).
    iii.   Reasonable doubt instruction.   The defendant claims
    that the trial judge's instruction on reasonable doubt created a
    substantial likelihood of a miscarriage of justice because it
    "was identical to the instruction that this court criticized and
    modified prospectively" in Commonwealth v. Russell, 
    470 Mass. 464
    , 477-478 (2015).   Here, the trial judge instructed:
    "Proof beyond a reasonable doubt does not mean proof beyond
    all possible doubt, for everything in the lives of the
    human beings is open to some possible or imaginary doubt.
    On the other hand, it is not enough for the Commonwealth to
    establish a probability, even a strong probability, that
    the defendant is more likely to be guilty than not
    guilty. . . . [P]roof beyond a reasonable doubt is proof
    that leaves you firmly convinced of the defendant's guilt.
    There are very few things in this world that we know with
    absolute certainty, and in criminal cases the law does not
    require proof that overcomes every possible doubt. If,
    based on your consideration of the evidence, you are firmly
    convinced that the defendant is guilty of the crime
    charged, you must find him guilty. If, on the other hand,
    you think there is a real possibility that he is not
    guilty, you must give him the benefit of the doubt and find
    him not guilty."
    Contrary to the defendant's assertion, the problematic language
    in Russell was not used in the trial judge's instruction here.
    See id. at 477 ("moral certainty" language required further
    clarification).19   Further, the trial judge's instruction
    19We also stated in Commonwealth v. Russell, 
    470 Mass. 464
    ,
    479 (2015), that the new instruction provided therein was to
    30
    contains language we did not deem improper in Russell.      See id.
    at 471-474 (rejecting argument that "firmly convinced" language
    lowered Commonwealth's burden of proof, or that "real
    possibility" language shifted burden of proof).   Thus, the
    defendant's argument is without merit.
    iv.    Additional instruction on criminal responsibility.
    For the first time on appeal, the defendant argues that the jury
    should have been instructed that his "failure to take his
    prescribed medication did not preclude a finding that he was not
    criminally responsible."    The defendant asserts that because the
    jury were not provided with this instruction, there was a
    substantial likelihood of a miscarriage of justice.   The
    defendant's argument assumes that, without such an instruction,
    the jury may have found him criminally responsible on the basis
    of his failure to take his prescribed medication.   In support of
    his argument, he cites two prior cases involving instructions on
    voluntary alcohol or drug usage, Commonwealth v. Berry, 
    457 Mass. 602
     (2010), and Commonwealth v. DiPadova, 
    460 Mass. 424
    (2011).20
    apply prospectively, not retroactively.    See Commonwealth v.
    Rakes, 
    478 Mass. 22
    , 48 n.23 (2017).
    20Commonwealth v. Berry, 
    457 Mass. 602
     (2010), and
    Commonwealth v. DiPadova, 
    460 Mass. 42
     (2011), were decided
    after the defendant's trial, but while his case was pending on
    direct appellate review. Thus, we must still decide whether the
    31
    In Berry, 
    457 Mass. at 618
    , we set out new jury
    instructions for cases involving the interplay of drug or
    alcohol usage and lack of criminal responsibility:
    "Where a defendant has an active mental disease or defect
    that caused her to lose the substantial capacity to
    appreciate the wrongfulness of her conduct or the
    substantial capacity to conform her conduct to the
    requirements of the law, the defendant's consumption of
    alcohol or another drug cannot preclude the defense of lack
    of criminal responsibility."
    We also stated that "[w]here the Commonwealth offers evidence
    that the defendant knew or had reason to know of the effects of
    drugs or alcohol on her latent mental disease or defect, or on
    the intensification of her active mental disease or defect," an
    additional instruction must be provided.    
    Id.
     at 617 n.9.21
    absence of the defendant's proposed instruction created a
    substantial likelihood of a miscarriage of justice. See
    Commonwealth v. Johnston, 
    467 Mass. 674
    , 704 (2014).
    21   That instruction was as follows:
    "However, if the Commonwealth has proved beyond a
    reasonable doubt that the defendant consumed drugs or
    alcohol knowing or having reason to know that the drugs or
    alcohol would activate a latent mental disease or intensify
    an active mental disease, causing her to lose the
    substantial capacity to appreciate the wrongfulness of her
    conduct or the substantial capacity to conform her conduct
    to the requirements of the law, then you would be warranted
    in finding the defendant criminally responsible for a crime
    in which you find she knowingly participated. In deciding
    what the defendant had reason to know about the
    consequences of her consumption of drugs or alcohol, you
    should consider the question solely from the defendant's
    point of view, including her mental capacity and her past
    experience with drugs or alcohol."
    32
    In DiPadova, we further stated:
    "As in Berry, in this case, given the absence of a proper
    instruction, the jury could have misinterpreted the model
    instruction and concluded, erroneously, that even if the
    defendant's mental illness by itself caused him to lack
    substantial capacity, 'because [he] had consumed [drugs]
    that contributed to [his] incapacity, that would render the
    lack of criminal responsibility defense moot.'"
    DiPadova, 
    460 Mass. at 435-436
    , quoting Berry, 
    457 Mass. at 618
    .
    Unlike in Berry, there was also evidence in DiPadova, 
    supra,
    that the defendant "knew at the time of the murder that drugs
    intensified the symptoms of his mental illness."   DiPadova,
    
    supra at 436-437
    .   We therefore clarified that the jury should
    have been instructed
    "(1) if the defendant's mental illness did not reach the
    level of a lack of criminal responsibility until he
    consumed drugs, he was criminally responsible if he knew
    (or should have known) that the consumption would have the
    effect of intensifying or exacerbating his mental
    condition; and, in contrast, (2) if the defendant's mental
    illness did reach the level of lack of criminal

    drugs, it was irrelevant whether he took drugs knowing that
    they would exacerbate that condition."
    
    Id. at 437

    The concerns at issue in Berry and DiPadova are markedly
    different from the ones presented here.   In each case, the jury
    received erroneous instructions regarding the interaction of
    mental illness and the voluntary consumption of alcohol or
    Berry, 
    457 Mass. at
    617 n.9.
    33
    drugs, which suggested that the consumption of the alcohol or
    drugs would negate a defense of lack of criminal responsibility.
    Here, the defendant does not identify any specific instruction
    as erroneous, such that it created juror confusion.    Nor could
    he.   As the trial judge remarked, "one thing I am not going to
    instruct [the jury] on is anything about the consumption of
    alcohol or substances.   There's just no evidence of that.       So I
    don't think this is an appropriate case for that."    No
    instruction on the use of drugs, or lack thereof, was requested
    by either party, and none was given.   Further, we discern
    nothing in the trial judge's instructions on criminal
    responsibility that would lead jurors to conclude that the
    defendant's failure to take his prescribed medication precluded
    the jury from finding him not criminally responsible.      The
    instructions appropriately focused the jury on whether the
    defendant was criminally responsible at the time of the murder,
    not on the effect, if any, that the failure to take prescribed
    medicine could have on this determination.    Cf. Commonwealth v.
    Shin, 
    86 Mass. App. Ct. 381
    , 388 (2014).     Thus, the jury
    instructions in this case do not create the same potential for
    juror confusion as existed in Berry or DiPadova.22
    We further note that the failure to take prescription
    22
    medication is not the same as the voluntary consumption of drugs
    or alcohol. See State v. Eager, 
    140 Haw. 167
    , 175 (2017).

    Although defense counsel did refer to the defendant's
    failure to take his medication, stating in closing argument that
    "[u]nless properly treated and medicated the disease takes over,
    and that's what happened to [the defendant]," the Commonwealth
    never introduced evidence or argued at trial that the defendant
    was criminally responsible because he voluntarily chose not to
    take the medication that treated his mental illness.   To the
    contrary, the Commonwealth primarily argued that the defendant's
    mental illness did not render him criminally irresponsible to
    begin with.   The prosecution only referred to the defendant's
    failure to take his medication to express skepticism that it
    negatively affected his behavior.   The prosecutor stated in her
    closing argument that "[i]t's a disease that waxes and wanes,
    that cycles over months, that even stopping his medications
    . . . would take days, weeks, or month[s] for the effect of that
    to be noticeable."23   In these circumstances, where the defendant
    There are many reasons why an individual may fail to take his or
    her prescribed medication. See Commonwealth v. Shin, 
    86 Mass. App. Ct. 381
    , 388 (2014) ("[M]entally ill people fail to take
    prescribed medication for a myriad of reasons, including, for
    example, side effects that may be otherwise dangerous to their
    health. . . . In addition, some people are unable to obtain the
    appropriate medication because of lack of money or access to
    medical care, or problems with necessary paperwork . . .").
    23Further, the prosecutor had elicited testimony from the
    Commonwealth's expert that failure to take the defendant's mood
    stabilizing medication "would take weeks, months . . . to have
    an [e]ffect on this -- of the peaks and valleys [of the
    35
    argues for an instruction on a theory of criminal responsibility
    that was not presented at trial, we conclude that no such
    instruction was required.     Cf. Commonwealth v. Harris, 
    464 Mass. 425
    , 434-435 (2013) (no curative instruction required where,
    evaluating jury instructions as whole, no jury could have
    improperly concluded Commonwealth was relieved of burden of
    proof).
    c.    Right to jury-waived trial.    The defendant requested a
    jury-waived trial, but his request was denied pursuant to G. L.
    c. 263, § 6, which does not provide defendants in a capital case
    the ability to waive their right to a jury trial.    The defendant
    asks that we find this statute unconstitutional, and in so
    doing, overturn our holding in Commonwealth v. Francis, 
    450 Mass. 132
    , 137 (2007) (concluding G. L. c. 263, § 6, does not
    violate defendants' equal protection or due process rights).     In
    support of this argument, the defendant asserts that jurors are
    biased against finding defendants not criminally responsible,
    and that jurors may have difficulty understanding instructions
    on criminal responsibility.    Much like in Francis, these
    defendant's mood]. It's not like a diabetic going off instantly
    today and tomorrow near trouble with their blood sugar. This is
    a chemical that kind of the brain is in over a long period of
    time. It takes the peaks and the valleys off. Helps some
    people. But it -- sometimes even on [the medication], a
    person's going to rocket right through the high into a manic
    episode, manic psychosis, that requires hospitalization."

    "arguments are policy matters suitable for legislative
    consideration," not judicial intervention.   Id.24
    d.   Review under G. L. c. 278, § 33E.   We have reviewed the
    record pursuant to G. L. c. 278, § 33E, and discern no basis to
    set aside or reduce the verdict of murder in the first degree or
    to order a new trial.   Accordingly, we decline to exercise our
    authority.
    Judgments affirmed.
    24 The defendant also notes that the third conviction of a
    habitual offender is considered a "capital case" for the
    purposes of G. L. c. 278, § 33E, see G. L. c. 279, § 25 (b), but
    is not considered a "capital case" under G. L. c. 263, § 6.
    Thus, "three-strike" habitual offenders are entitled to the same
    § 33E review as defendants convicted of murder in the first
    degree, but may still waive their right to a jury trial. The
    defendant fails to expand on this argument, but presumably sees
    this as an equal protection violation. As we stated in
    Commonwealth v. Francis, 
    450 Mass. 132
    , 135 (2007), "[i]t is
    reasonable for the Legislature to treat defendants facing a
    charge of murder in the first degree differently from other
    defendants." Further, we acknowledged that there was a
    difference between the definition of "capital" under G. L.
    c. 278, § 33E, and that under G. L. c. 263, § 6, but rejected
    the argument that any such difference requires allowing
    defendants charged with murder in the first degree the ability
    to waive their right to a jury trial. See Francis, supra at
    137. For substantially the same reasons stated in Francis, we
    discern no equal protection violation here.
