    SUMMARY
    Habeas Corpus / Death Penalty
    The panel filed an order amending an opinion filed
    November 9, 2015, and denying a petition for panel rehearing
    or rehearing en banc, in a case in which the panel affirmed
    the district court’s denial of California state prisoner Conrad
    Zapien’s habeas corpus petition challenging his first degree
    murder conviction and death sentence.
    In the amended opinion, the panel:
    •   rejected Zapien’s argument that the California
    Supreme Court unreasonably rejected his claim that
    he was denied due process when a prosecution
    investigator, who found a sealed envelope containing
    an audio tape explaining defense strategy, destroyed
    the tape.
    •   held that the California Supreme Court did not
    unreasonably reject Zapien’s arguments that his rights
    under the Confrontation Clause were violated by
    (1) the trial court’s admission of statements that
    Zapien’s sister made at a preliminary hearing and
    (2) the introduction of multi-level hearsay testimony.
    •   held that the California Supreme Court did not
    unreasonably reject Zapien’s claims of ineffective
    assistance of counsel at the guilt phase.

    •   held that the California Supreme Court did not

    OPINION
    KOZINSKI, Circuit Judge:
    Conrad Zapien was convicted of first degree murder and
    sentenced to death by the state of California. He challenges
    both his conviction and sentence.
    BACKGROUND
    In 1987, Zapien was found guilty of killing Ruby
    Gonzalez in her home by shooting her four times and
    stabbing her five times. Zapien was a heroin addict,
    desperate for money, and Ruby was the mistress of his
    sister’s husband. The prosecution’s case at trial was that
    Zapien intended to rob Ruby’s home after being told by his
    sister that there was money and jewelry inside. The
    prosecution theorized that Ruby surprised and confronted
    Zapien, who killed her and fled town the next day. Zapien
    spent the months after Ruby’s death living under pseudonyms
    in various Christian homes, before eventually being found
    and arrested in Arizona.
    Before Zapien’s trial began, prosecutor Gary Van Camp
    and his investigator Harry Heidt found a sealed envelope
    ZAPIEN V. MARTEL                         5
    bearing the name of Zapien’s trial counsel. The envelope
    contained an audio tape explaining the defense’s strengths
    and weaknesses. Heidt later claimed that Van Camp told him
    to listen to the tape, but he destroyed it instead. Heidt
    eventually revealed the incident and Zapien’s counsel moved
    to have all charges dismissed. The trial court denied the
    motion, finding that Heidt had not listened to the tape.
    The jury convicted Zapien of first degree murder and
    found a “special circumstance” which made Zapien death
    eligible—that the killing was committed during the course of
    a burglary and an attempted robbery. The jury sentenced
    Zapien to death.
    Zapien appealed his conviction and sentence to the
    California Supreme Court, which denied his appeal in a
    lengthy reasoned opinion in 1993. See People v. Zapien, 
    846 P.2d 704
     (Cal. 1993) (in bank). In 1996, Zapien filed a
    federal habeas petition that was stayed pending exhaustion of
    state remedies. Zapien then filed a state habeas petition in the
    California Supreme Court. In 1998, the California Supreme
    Court denied all but four of Zapien’s claims on timeliness
    grounds and, in the alternative, summarily denied all of his
    claims on the merits. Zapien then returned to federal court.
    Although he was granted an evidentiary hearing on some of
    his ineffective assistance of counsel claims, the district court
    ultimately denied them all.
    DISCUSSION
    1. The Tape
    Zapien argues he was denied due process when Heidt
    destroyed the defense strategy tape. The California Supreme
    6                    ZAPIEN V. MARTEL
    Court concluded that, though Heidt “clearly acted wrongly in
    disposing of the envelope and its contents, . . . this improper
    act did not deprive [Zapien] of due process of law or
    otherwise deny [him] a fair trial” because there was no
    “‘conscious effort to suppress exculpatory evidence.’”
    Zapien, 
    846 P.2d at 723
     (quoting California v. Trombetta,
    
    467 U.S. 479
    , 488 (1984)). Zapien argues that this was an
    unreasonable application of Trombetta and Arizona v.
    Youngblood, 
    488 U.S. 51
     (1988).
    However, both Youngblood and Trombetta dealt with the
    destruction of potentially exculpatory evidence—not, as here,
    the destruction of attorney-client work product. See
    Youngblood, 488 U.S. at 57–58; Trombetta, 
    467 U.S. at
    486–87. Zapien asserts the novel theory that destroying the
    tape constituted the destruction of exculpatory evidence
    because, had the tape been recovered, it could have been
    tested. Such testing apparently would have revealed that the
    tape had been listened to and thus that misconduct had
    occurred. Revealing the alleged misconduct would have been
    “exculpatory,” according to Zapien, because it would have
    required the case be dismissed.
    Zapien’s tortuous chain of reasoning is not supported, let
    alone “clearly established,” by Youngblood, Trombetta or any
    other Supreme Court case. See 
    28 U.S.C. § 2254
    (d)(1) (a
    writ of habeas corpus may not be granted unless the state
    court reached a “decision that was contrary to, or involved an
    unreasonable application of, clearly established Federal law,
    as determined by the Supreme Court of the United States”).
    Zapien provides no authority for the proposition that a due
    ZAPIEN V. MARTEL                                 7
    process violation can be premised on the destruction of
    information already known to the defense.1
    Zapien next argues that it was unreasonable for the
    California Supreme Court to adopt the Superior Court’s
    factual finding that Heidt didn’t listen to the tape. Because
    Zapien is unable to explain how listening to a defense
    strategy tape constitutes a due process violation, he likely
    wouldn’t have a viable claim even if the state court’s factual
    determination had been unreasonable. See Wilson v.
    Corcoran, 
    562 U.S. 1
    , 5–6 (2010) (holding that a state court’s
    unreasonable factual determination is only relevant in a
    federal habeas proceeding to the extent it results in a decision
    that violates federal law). In any event, our review of a state
    appellate court’s affirmance of a state trial court’s credibility
    determination “is doubly deferential.” Briggs v. Grounds,
    
    682 F.3d 1165
    , 1170 (9th Cir. 2012). “[U]nless the state
    appellate court was objectively unreasonable in concluding
    that a trial court’s credibility determination was supported by
    [the record], we must uphold it.” 
    Id.
     Here, even if
    “[r]easonable minds reviewing the record might disagree” as
    to the truthfulness of Heidt’s testimony, “that does not suffice
    to supersede the trial court’s credibility determination.” Rice
    v. Collins, 
    546 U.S. 333
    , 341–42 (2006).
    1
    Zapien’s claim is more readily cognizable as a violation of his right
    to counsel under the Sixth Amendment, see United States v. Danielson,
    
    325 F.3d 1054
    , 1070–71 (9th Cir. 2003), though, again, such a claim has
    not been clearly established by the Supreme Court. In any event, Zapien
    failed to bring this claim, either before us or in any prior state or federal
    proceeding.
    8                        ZAPIEN V. MARTEL
    2. Confrontation Clause
    Zapien next argues that his rights under the Confrontation
    Clause were violated when the trial court admitted various
    statements that his sister Inez—who refused to testify at
    trial—made at a preliminary hearing.2 Under the then-
    governing standards of Ohio v. Roberts, 
    448 U.S. 56
     (1980),
    abrogated by Crawford v. Washington, 
    541 U.S. 36
     (2004),
    the “adequate opportunity to cross-examine [a] witness” at a
    preliminary hearing typically provides “sufficient indicia of
    reliability” for statements from that hearing to be introduced
    at trial if the witness is unavailable. 
    Id. at 73
     (alteration
    omitted) (internal quotation marks omitted). Nonetheless,
    Zapien argues that the state court unreasonably applied
    Roberts because the government knew Inez had told lies
    during other parts of her preliminary hearing testimony
    (though not in the portions read to the jury). Even assuming
    Inez had in fact lied, Zapien fails to show that the California
    Supreme Court’s decision was an unreasonable application of
    Roberts. Preliminary hearing testimony falls within the
    heartland of those statements deemed reliable under Roberts,
    see 
    448 U.S. at 73
     (noting that “guarantees of
    trustworthiness” are found “in the accouterments of the
    preliminary hearing itself”), and Zapien can point to no case
    in which admitting preliminary hearing testimony has been
    2
    The trial court also allowed into evidence certain statements made by
    Inez during a police interview. The California Supreme Court found that
    Zapien was procedurally barred from raising the argument that admission
    of these interrogation statements violated his confrontation rights, because
    he did not contemporaneously object to their admission at trial. That
    dismissal on a procedural ground constitutes an independent and adequate
    basis for dismissing the claim, which we are barred from reviewing. See
    Coleman v. Thompson, 
    501 U.S. 722
    , 750 (1991).
    ZAPIEN V. MARTEL                         9
    held to violate the Confrontation Clause solely because other
    testimony by the absent witness is untrue.
    Zapien claims that his confrontation rights were also
    violated by the introduction at trial of multi-level hearsay
    testimony by Mariella Perez, a friend of Inez’s daughter
    Juanita. Perez testified that Juanita told her that Inez’s other
    daughter, “Little Inez,” had told Juanita that Zapien arrived
    at Inez’s house on the morning of the murder with blood on
    his shirt. An investigator also played a recording of Perez
    stating that Juanita told her that Little Inez saw Inez give
    Zapien her car keys. Both Juanita and Little Inez testified at
    trial: Little Inez denied seeing Zapien that day or talking to
    Juanita, and Juanita likewise denied the conversation. The
    California Supreme Court reasonably—indeed correctly—
    applied the holding in California v. Green that “the
    Confrontation Clause is not violated by admitting a
    declarant’s out-of-court statements, as long as the declarant
    is testifying as a witness and subject to full and effective
    cross-examination.” 
    399 U.S. 149
    , 158 (1970). Zapien
    argues here, as he did before the California Supreme Court,
    that Green is inapplicable in the context of multiple hearsay.
    But he cites no authority for that proposition, and the
    California Supreme Court reasonably rejected what it
    considered to be an “arbitrary rule based solely upon the
    number of levels of hearsay.” Zapien, 
    846 P.2d at 717
    .
    Zapien also argues that the admission of Perez’s
    statements was such an egregious violation of California
    evidentiary law that it constituted a due process violation. It
    is not at all clear that there was a violation of California law,
    let alone one so fundamentally unfair that it amounted to a
    due process violation. In any event, we’ve held that, “[u]nder
    AEDPA, even clearly erroneous admissions of evidence that
    10                        ZAPIEN V. MARTEL
    render a trial fundamentally unfair may not permit the grant
    of federal habeas corpus relief if not forbidden by clearly
    established [Supreme Court precedent].”          Holley v.
    Yarborough, 
    568 F.3d 1091
    , 1101 (9th Cir. 2009) (internal
    quotation marks omitted). Because there is no Supreme
    Court case establishing the fundamental unfairness of
    admitting multiple hearsay testimony, Holley prohibits us
    from finding in Zapien’s favor on this due process claim.
    3. Ineffective Assistance of Counsel at the Guilt
    Phase
    Zapien brings several ineffective assistance of counsel
    claims, all of which were summarily denied by the California
    Supreme Court.3 When confronted with a state court’s
    summary denial, we “must determine what arguments or
    theories . . . could have supported . . . the state court’s
    decision; and then . . . ask whether it is possible fairminded
    jurists could disagree that those arguments or theories are
    inconsistent with the holding in a prior decision of [the
    Supreme] Court.” Harrington v. Richter, 
    562 U.S. 86
    , 102
    (2011). Our review of Zapien’s ineffective assistance claims
    is doubly deferential: “We take a highly deferential look at
    counsel’s performance through the deferential lens of
    3
    Zapien’s ineffective assistance claims were first presented to the state
    courts in a habeas petition over three years after the denial of Zapien’s
    direct appeal. In addition to summarily denying these claims on the
    merits, the California Supreme Court dismissed them on timeliness
    grounds. They should therefore be procedurally defaulted. However, the
    state does not raise procedural default before us, nor did it do so before the
    district court. Although we may raise the issue of procedural default sua
    sponte under exceptional circumstances, see Day v. McDonough, 
    547 U.S. 198
    , 209 (2006), we decline to do so here.
    ZAPIEN V. MARTEL                        11
    § 2254(d).” Cullen v. Pinholster, 
    563 U.S. 170
    , 190 (2011)
    (internal quotation marks and citation omitted).
    Zapien first argues that his trial counsel was ineffective
    for not vigorously impeaching the testimony of Ruby’s
    daughter Marci. Thirteen-year-old Marci was an eyewitness
    to the murder and testified that during the attack she heard her
    mother say, “Chato, leave me alone. I will give you the
    money and the jewelry.” “Chato” was Zapien’s brother—
    who resembled Zapien—and was in prison at the time of the
    killing. Marci’s testimony was harmful to Zapien both
    because it showed that he looked like the assailant and
    because it suggested he entered the home with an intent to
    commit a robbery, the “special circumstance” that made
    Zapien death eligible. Zapien argues that his trial counsel
    should have impeached Marci with statements she made
    during Zapien’s preliminary hearing—and statements made
    to neighbors and the police—where she either failed to
    mention “the money and the jewelry” or implied that Ruby
    was offering the intruder “the money and the jewelry” rather
    than responding to a demand. Zapien also argues that trial
    counsel should have attempted to undermine Marci’s account
    with testimony by a child memory expert, who would
    apparently have explained that, since Marci had just awoken
    from a violent dream, her memories of the attack may have
    been faulty.
    However, a fairminded jurist could conclude that counsel
    made a strategic decision in how he approached Marci’s
    impeachment. Even if counsel had tried to impeach Marci in
    the manner Zapien now suggests, a jury would likely still
    have found her testimony credible. Marci’s physical
    description of the attacker wearing a plaid shirt and a vest
    was corroborated by the discovery of an abandoned plaid
    12                   ZAPIEN V. MARTEL
    shirt and vest covered in Ruby’s blood. Marci was by all
    accounts highly sympathetic on the stand. And her memory
    of the event was vivid and prolonged—involving not merely
    witnessing the attack, but also hitting the assailant with a
    broom and trying to protect her sisters. Aggressively
    attempting to impeach Marci’s testimony may therefore have
    alienated the jury, without doing much to undermine her
    credibility. Zapien’s trial counsel took a different tack. He
    stressed that Marci’s testimony, even if true, failed to
    establish beyond a reasonable doubt that Zapien was the
    assailant. Under the circumstances, we cannot conclude that
    all fairminded jurists would say such a strategy rendered
    counsel’s assistance ineffective. See Harrington, 
    562 U.S. at 102
    ; Strickland v. Washington, 
    466 U.S. 668
    , 681, 688
    (1984).
    Zapien next claims that trial counsel should have
    introduced the testimony of Ruby’s two other children, Joni
    and Jessica, who also witnessed the murder. Joni told the
    police that the attacker was wearing a dark ski mask, and both
    Joni and Jessica said they heard a car speeding away after the
    attack. Zapien claims that the ski mask testimony would have
    undermined Marci’s account that Ruby thought the assailant
    was Chato, and the car sound would have undermined
    Mariella Perez’s story that Zapien needed a car from Inez
    after the murder.
    However, at the time of the murder, Joni and Jessica were
    eight and six respectively, much younger than the thirteen-
    year-old Marci. Not only was Marci’s story more precise and
    fleshed out than those of her sisters, it was also corroborated
    by the discovery of the plaid shirt and vest. Because of their
    youth, Joni and Jessica may have been unpredictable on the
    stand, and putting them through the ordeal of testifying could
    ZAPIEN V. MARTEL                       13
    have alienated the jury. There was only a small, perhaps
    infinitesimal, possibility that a jury would have believed them
    rather than Marci. On balance, the risks associated with
    calling them to testify outweighed the potential benefits.
    Accordingly, it is reasonable to conclude that counsel wasn’t
    ineffective in failing to call Joni and Jessica as witnesses.
    Zapien next argues that counsel should have moved to
    exclude the testimony of Lena Chacon and Michael Jimenez,
    two witnesses Zapien met at a Christian home shortly after
    the murder. Chacon testified at trial that Zapien told her that
    he shot someone during the robbery of a store and was using
    a pseudonym because he was wanted for murder in
    California. Jimenez testified that Zapien had told him about
    two separate shootings—one in which he shot someone, who
    Jimenez thought was a woman, and another during the
    robbery of a store. Zapien argues that trial counsel was
    ineffective for failing to move in limine to exclude Chacon’s
    and Jimenez’s testimony as irrelevant to Ruby’s murder.
    However, a review of the record reveals little basis upon
    which such a motion could plausibly have been successful.
    While both witnesses made vague and confusing statements
    during the preliminary hearing, their testimony clearly had
    the potential of being highly probative. Competent counsel
    could reasonably have concluded that moving to exclude their
    testimony on the grounds Zapien now suggests would have
    seemed frivolous.
    Zapien also criticizes counsel for eliciting testimony from
    Chacon at trial regarding the apparent store-robbery killing.
    But, review of the cross-examination transcript reveals that
    counsel acted reasonably. Chacon mentioned on the stand
    that Zapien had admitted shooting someone, but didn’t
    specify who the victim was. At that point, counsel made the
    14                   ZAPIEN V. MARTEL
    strategic decision to ask about the possibility of a second
    shooting in order to create doubt as to whether Zapien was
    referring to Ruby’s killing. Under our doubly deferential
    review, we cannot say the California Supreme Court erred in
    concluding that counsel’s representation was competent.
    Zapien also claims that counsel was ineffective by failing
    to object to several instances of inadmissible and prejudicial
    hearsay testimony. Zapien claims counsel should have
    objected on Confrontation Clause grounds to Sergeant
    Stevens’s testimony about what Inez told him. But counsel
    had cross-examined Inez at a preliminary hearing, and the
    California Supreme Court found that the same interest and
    motive existed in that cross-examination as at trial. The
    California Supreme Court’s determination that this testimony
    didn’t violate the Confrontation Clause wasn’t unreasonable.
    See Ohio v. Roberts, 
    448 U.S. 56
    , 72–73 (1980), abrogated
    by Crawford v. Washington, 
    541 U.S. 36
     (2004). The other
    hearsay statements Zapien complains about were cumulative
    of the evidence offered at trial and thus not prejudicial, even
    assuming that counsel should have objected to them.
    Finally, Zapien argues that counsel was ineffective for
    failing to introduce evidence suggesting that Zapien had a
    broken hand at the time of the murder and was therefore
    likely incapable of killing Ruby. Zapien argued in his state
    habeas petition that trial counsel should have introduced
    testimony by Dr. James Day, a radiologist who allegedly
    treated Zapien for a hand injury twelve days before Ruby’s
    murder. According to Zapien, Day’s testimony would have
    shown that Zapien was injured, had a cumbersome cast
    placed on his right hand and was likely physically incapable
    of making the deep stab wounds found on Ruby’s body. But
    even if counsel was in possession of medical records showing
    ZAPIEN V. MARTEL                       15
    that Zapien was treated for a fracture, a fairminded jurist
    could conclude that counsel’s failure to pursue this line of
    defense did not amount to ineffective assistance. A
    fairminded jurist could also conclude that this single piece of
    medical evidence would not have created a reasonable
    likelihood of a different outcome at trial, given the other
    evidence of Zapien’s guilt and, most significantly, the fact
    that the hand injury (as Zapien concedes) would not have
    made the attack impossible.
    4. Ineffective Assistance of Counsel at the Sentencing
    Phase
    Zapien argues that counsel was ineffective for failing to
    introduce various pieces of mitigating evidence at the
    sentencing phase. Zapien first claims that counsel should
    have introduced further evidence regarding his traumatic
    upbringing, which would have revealed that Zapien’s father
    was a violent alcoholic who brutally beat Zapien’s mother in
    front of the children and abandoned the family when Zapien
    was five. Zapien’s father later returned and carried on a
    thirteen-year incestuous relationship with Zapien’s sister that
    ended when Zapien’s father shot her to death before killing
    himself.
    Meanwhile, Zapien’s mother worked as a prostitute and
    a “coyote” smuggling undocumented immigrants across the
    Mexican border. Two men with whom she was involved
    impregnated two of Zapien’s sisters. Zapien’s mother also
    carried a gun and drank at local bars, got men drunk and stole
    their wallets, and neglected her children, who grew up on the
    streets malnourished and hungry. She frequently beat Zapien
    and his siblings.
    16                   ZAPIEN V. MARTEL
    In addition, evidence in the habeas record indicates that
    Zapien’s grandmother, with whom Zapien lived, also worked
    as a coyote. She routinely abused Zapien, whipping him with
    a rubber hose, often for acts committed by a sibling. She
    forced Zapien and his siblings to perform manual labor in the
    fields, and threw rocks at them when they took a break from
    working. On one occasion, she killed Zapien’s pet rabbit and
    served it to him for dinner, which Zapien learned only after
    he had eaten the meal.
    Zapien’s uncle, who also lived in the grandmother’s
    house, was a major drug dealer with multiple drug
    convictions; he used and sold heroin, and made drugs
    available to Zapien from a young age. Zapien was sentenced
    to juvenile hall for drug- and alcohol-related offenses when
    he was fifteen years old. He was a heroin addict by the age
    of twenty.
    In addition to his drug addiction, Zapien had a history of
    blackouts and was diagnosed with syphilis. He had also been
    exposed to pesticides while working as a tree sprayer, and
    suffered numerous blows to the head at a young age.
    Zapien contends that there is a reasonable probability that
    this sordid background evidence would have moved at least
    one juror to spare Zapien’s life, and that it was unreasonable
    for the California Supreme Court to conclude otherwise,
    particularly given that Zapien’s jury—without having heard
    this evidence—deliberated for three days before returning a
    death verdict.
    The importance and relevance of social history and
    mental health at the sentencing phase of a capital case is
    clearly established by the United States Supreme Court, and
    ZAPIEN V. MARTEL                      17
    was clearly established both at the time of defendant’s
    penalty phase in 1987 and at the time the California Supreme
    Court denied Zapien’s ineffective assistance of counsel
    claims in 1998. See California v. Brown, 
    479 U.S. 538
    , 545
    (1987) (O’Connor, J., concurring); Eddings v. Oklahoma,
    
    455 U.S. 104
    , 114–15 (1982); Lockett v. Ohio, 
    438 U.S. 586
    ,
    604–05 (1978) (plurality opinion); Woodson v. North
    Carolina, 
    428 U.S. 280
    , 303–05 (1976) (plurality opinion).
    However, the Supreme Court has clarified that Strickland
    does not require penalty phase counsel to “investigate every
    conceivable line of mitigating evidence.” Wiggins v. Smith,
    
    539 U.S. 510
    , 533 (2003).
    Here, defense counsel sought out—and introduced—a
    considerable amount of mitigating evidence. For example,
    counsel called a cultural anthropologist who testified as an
    expert about the “physical, social, [and] economic isolation,”
    in the La Colonia community in Oxnard. Counsel also
    introduced testimony from a medical doctor about the effects
    of heroin addiction, and solicited character testimony from
    Zapien’s friends and family. Through this evidence, defense
    counsel introduced a picture of Zapien as a kind and
    affectionate child who was raised in an overcrowded, drug-
    infested and impoverished “slum” without parental
    supervision or a male role model. Counsel also appealed to
    the notion of lingering doubt by introducing information
    regarding the prosecution’s possible misconduct, which
    called into question the reliability of the prosecution’s
    evidence. “[C]ounsel’s decision not to mount an all-out
    investigation into petitioner’s background in search of
    mitigating circumstances was supported by reasonable
    professional judgment.” Burger v. Kemp, 
    483 U.S. 776
    , 794
    (1987); cf. Porter v. McCollum, 
    558 U.S. 30
    , 39–40 (2009)
    (per curiam) (finding deficient performance during the
    18                   ZAPIEN V. MARTEL
    penalty phase where “counsel did not even take the first step
    of interviewing witnesses or requesting records” and “thus
    failed to uncover and present any evidence of [petitioner’s]
    mental health or mental impairment”); Wiggins, 
    539 U.S. at 533
     (finding deficient performance during the penalty phase
    where “counsel’s investigation of petitioner’s background
    was limited to [two court-commissioned] records,” and
    holding that “strategic choices made after less than complete
    investigation are reasonable only to the extent that reasonable
    professional judgments support the limitations on
    investigation” (internal quotation marks and citation
    omitted)).
    Furthermore, as the district court correctly found,
    mitigating evidence of drug dependency and an abusive
    family history “can be a two-edged sword that [a jury] might
    find to show future dangerousness” or use to conclude that a
    defendant is “simply beyond rehabilitation.” Pinholster,
    
    563 U.S. at 201
    (internal quotation marks omitted) (quoting
    Atkins v. Virginia, 
    536 U.S. 304
    , 321 (2002)). Given that
    “strategic choices made after thorough investigation of law
    and facts relevant to plausible options are virtually
    unchallengeable,” Strickland, 
    466 U.S. at 690
    , the California
    Supreme Court was not unreasonable in denying this claim.
    Zapien also argues that trial counsel should have
    introduced evidence of Zapien’s psychiatric and neurological
    problems. However, it is not clear that Zapien actually
    suffers from any such problems. All that was presented for
    state habeas review was evidence that Zapien’s family
    members suffered from mental illness, and that he was
    exposed to various things—like drugs, pesticides and blows
    to the head—that could have led to him developing a brain
    injury. The closest thing to an actual diagnosis of a mental
    ZAPIEN V. MARTEL                        19
    disorder is a doctor’s testimony during Zapien’s federal
    evidentiary hearing that he may have suffered from PTSD.
    However, that evidence was never presented in Zapien’s state
    petition, and we are not permitted to consider it here.
    Pinholster, 
    563 U.S. at
    181–82, 186. And, even if it were
    before us, there is no indication that counsel knew or should
    have known that Zapien suffered from such a disorder.
    Failure to introduce evidence of PTSD, therefore, didn’t
    amount to ineffective assistance of counsel.
    Zapien next argues that counsel was ineffective for failing
    to properly prepare two experts at sentencing. Both experts
    gave generic testimony—one about the socioeconomic profile
    of Zapien’s neighborhood and the other about the effects of
    heroin abuse—but neither expert met with Zapien or tailored
    his testimony to Zapien’s particular circumstances. Zapien
    can point to no case holding that failure to have an expert
    meet with a defendant constitutes ineffective assistance. And,
    in any event, if defense counsel had presented experts who
    “personalized” their testimony to Zapien, reasonable jurists
    could debate whether such expert testimony would have
    opened the door to evidence (or more evidence) regarding
    Zapien’s heroin addiction as well as whether Zapien suffered
    from anti-social personality disorder—topics that may not
    have inured to Zapien’s benefit in the eyes of the jury.
    Finally, Zapien argues that counsel was ineffective
    because he didn’t adequately rebut the prosecution’s use of
    Zapien’s prior manslaughter conviction as an aggravating
    factor. According to Zapien, counsel failed to explain to the
    jury that the victim in that crime had attacked and raped
    Zapien’s girlfriend a few days before the killing. Instead,
    trial counsel sought to obscure the particular facts of Zapien’s
    20                   ZAPIEN V. MARTEL
    prior crime and emphasize the lower degree of culpability
    required for a manslaughter conviction.
    In Wong v. Belmontes, 
    558 U.S. 15
     (2009) (per curiam),
    the Supreme Court reversed this court’s grant of habeas relief
    based on the purported prejudicial ineffective assistance of
    Belmontes’s trial counsel and reinstated the petitioner’s death
    sentence. Belmontes was convicted of murdering a woman
    during a burglary. 
    Id. at 15
    . At sentencing, Belmontes’s
    counsel presented nine witnesses who testified about
    Belmontes’s difficult childhood. 
    Id. at 19
    . Nevertheless,
    Belmontes argued that counsel should have offered more
    mitigating evidence. 
    Id. at 16
    . However, Belmontes had a
    prior conviction for accessory after the fact to voluntary
    manslaughter. 
    Id. at 17
    . There was substantial evidence that
    Belmontes had, in fact, committed murder but pleaded guilty
    to a lesser offense, and counsel built his mitigation strategy
    around the “overriding need” to exclude the details of
    Belmontes’s criminal history. 
    Id. at 18
    . The Supreme Court
    held that trial counsel had reasonably tailored his mitigation
    case to avoid opening the door to the aggravating evidence of
    Belmontes’s manslaughter conviction, which would have
    become admissible had the unoffered evidence been received.
    See 
    id.
     at 25–26. As the Supreme Court explained, “[a]
    heavyhanded case to portray Belmontes in a positive light . . .
    would have invited the strongest possible evidence in
    rebuttal—the evidence that Belmontes was responsible for
    not one but two murders.” 
    Id. at 25
    .
    A fairminded jurist could conclude that counsel faced a
    similar dilemma regarding the details of Zapien’s prior
    conviction. Zapien’s jury knew that he had previously been
    convicted for stabbing a man to death with a machete. And,
    while Zapien pled to voluntary manslaughter, there was
    ZAPIEN V. MARTEL                        21
    evidence that the killing was actually premeditated—evidence
    that would likely have been revealed to the jury had counsel
    elaborated on the details of the attack. Accordingly, we must
    conclude that the California Supreme Court could have
    reasonably determined that Zapien failed to show that
    counsel’s representation was constitutionally inadequate, or
    that he suffered prejudice from the lack of additional
    mitigating evidence.
    5. Juror Prejudice
    Zapien’s final argument is that his right to an impartial
    jury was violated when the trial court failed to dismiss a juror
    who admitted to hearing a news report that suggested Zapien
    would hurt his guards if he were given the death penalty. The
    trial court held a hearing in which the judge questioned the
    juror, and eventually ruled that he was capable of being
    impartial. The California Supreme Court rejected Zapien’s
    argument that the trial court erred in this credibility
    determination, and concluded that the juror’s knowledge of
    the news report was harmless.
    Zapien argues that the California Supreme Court’s
    decision was an unreasonable application of Mattox v. United
    States, 
    146 U.S. 140
     (1892), which established a rebuttable
    presumption of prejudice when a juror is exposed to
    information garnered outside of the trial. However, in
    substance, the California Supreme Court applied the Mattox
    presumption when it held that the trial court properly
    determined the juror could be impartial. Once again, our
    posture is doubly deferential: Zapien asks us to hold that the
    California Supreme Court was unreasonable in failing to find
    that the trial court made an unreasonable credibility
    determination about whether the juror was prejudiced.
    22                  ZAPIEN V. MARTEL
    Zapien has no non-speculative basis for that conclusion.
    Instead, he effectively advocates for a per se rule in which
    exposure to any out-of-trial information automatically
    requires juror dismissal. Such an approach is plainly
    inconsistent with Mattox and its progeny. As with Zapien’s
    other claims, the California Supreme Court’s decision was at
    least reasonable.
    AFFIRMED.
