    v.
    MAURICE GERALD STESKAL,
    Defendant and Appellant.
    S122611
    Orange County Superior Court
    99ZF0023
    April 29, 2021
    Justice Kruger authored the opinion of the Court, in which
    Chief Justice Cantil-Sakauye and Justices Corrigan, Liu,
    Cuéllar, Groban, and Jenkins concurred.
    PEOPLE v. STESKAL
    S122611
    Opinion of the Court by Kruger, J.
    A jury convicted defendant Maurice Gerald Steskal of the
    first degree murder of Orange County Deputy Sheriff Bradley J.
    Riches. (Pen. Code, § 187.) The jury found true a special
    circumstance allegation that Steskal intentionally killed a peace
    officer engaged in the performance of his duties (id., § 190.2,
    subd. (a)(7)), as well as an allegation that Steskal personally
    used a firearm in the commission of the offense (id., former
    §§ 12022.5, subd. (a), 12022.53, subd. (d)). The trial court
    declared a mistrial when the jury was unable to reach a penalty
    verdict. After a penalty retrial, the jury returned a verdict of
    death. This appeal is automatic. (Cal. Const., art. VI, § 11,
    subd. (a); Pen. Code, § 1239, subd. (b).) We affirm the judgment.
    I.   BACKGROUND
    A. Guilt Phase
    1. Prosecution evidence
    On the night of June 11, 1999, Steskal was seen near the
    residence of his wife, Nannette Steskal, from whom he was then
    separated.1 Close to midnight, a neighbor of Nannette’s heard
    a commotion in their apartment complex. The neighbor then
    saw Steskal outside smashing a piece of furniture against the
    1

    surnames, we will refer to Nannette by her first name for clarity.

    wall and heard him slam a gate while cursing at the world and
    screaming that he hated everyone. The neighbor heard a
    woman trying to calm him. Steskal responded, “Fuck that, I
    have guns, I have ammunition.”
    Shortly after midnight, Steskal went into a 7-Eleven
    convenience store carrying a semiautomatic rifle. As he
    purchased cigarettes, he asked the clerk if she was afraid of his
    gun and told her it was to protect himself from the “fucking law.”
    An Orange County Sheriff’s Department (OCSD) deputy,
    Bradley Riches, drove by the 7-Eleven in his patrol car while
    Steskal was inside. Apparently seeing Steskal’s rifle through
    the glass front of the store, Deputy Riches doubled back while
    issuing a radio alert for other deputies to stand by. As Steskal
    completed his purchase, Deputy Riches pulled into the 7-Eleven
    parking lot with his overhead lights flashing. The clerk watched
    as Steskal walked out of the store and immediately began firing
    his rifle. Steskal shot Deputy Riches at close range, firing 30
    rounds in total, then returned to his car and drove away. When
    first responders arrived on the scene, they found Deputy Riches
    still seated in his car. It appeared he had unsnapped his holster
    but had been unable to pull his revolver before succumbing to
    his wounds.
    A criminalist testified about the bullet casings and other
    evidence found at the crime scene, identified photographs
    showing damage to the patrol car, and explained her efforts to
    determine the trajectory of the shots fired. The criminalist
    identified a photograph of Deputy Riches’s body at the hospital
    and a pathologist described Deputy Riches’s numerous injuries.
    An OCSD sergeant testified that the 7-Eleven where Deputy
    Riches had been killed was one of the few convenience stores
    open 24 hours a day and was therefore a regular meeting place
    2
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    for patrol deputies.
    OCSD deputies apprehended Steskal a few hours after the
    crime as he and Nannette drove away from her apartment. In
    Steskal’s car, deputies found over one hundred rounds of
    ammunition and a disassembled rifle later identified as the
    weapon used in the shooting. A blood screen found no drugs or
    alcohol in Steskal’s system.
    Steskal had other encounters with law enforcement in the
    months before Deputy Riches was killed. Approximately two
    and one-half months before the crime, a different OCSD deputy,
    Andre Spencer, stopped Steskal for a traffic violation and
    arrested him for possession of a small amount of marijuana and
    resisting an officer in the performance of official duties. During
    the stop, Deputy Spencer saw Steskal pound his hands on his
    steering wheel and became alarmed when Steskal exited his
    vehicle. Deputy Spencer drew his gun on Steskal, summoned
    additional deputies, and searched Steskal’s pants and shoes for
    contraband. Deputy Spencer stopped Steskal for another traffic
    violation one month later. Deputy Spencer reminded Steskal to
    take care of his prior tickets and ended the stop without
    incident.
    2. Defense evidence
    Steskal did not deny shooting Deputy Riches, but
    presented evidence intended to show that he was acting under a
    delusional fear when it occurred. Steskal’s sister and a variety
    of acquaintances testified that Steskal had been paranoid for
    many years and was particularly occupied by thoughts that law
    enforcement and government actors were following him and
    wished him harm. He had long kept an assault rifle that he
    slept with and carried with him everywhere. For most of his
    3
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    adult life, Steskal lived apart from others — on the roof of a shop
    where he worked, in a van, and in a small concrete bunker on
    an abandoned mining site owned by his brother-in-law. Even
    when living far from others, Steskal believed bad actors were
    seeking him out: He worked on an escape route from his bunker,
    wearing down a pickaxe as he tried to make a tunnel through
    granite, and ran through the woods looking for pursuers with
    blackberry juice rubbed on his skin to provide camouflage. In
    the months before the crime, Steskal spent much of his time
    living in a remote mountain camp. Although he was separated
    from his wife, he sometimes stayed with her. He believed her
    apartment was wiretapped and felt he was being monitored
    through her television. He was depressed and often talked
    about suicide.
    The lay witnesses observed that Steskal’s mental health
    deteriorated significantly after the two traffic stops conducted
    by Deputy Spencer: Steskal became even more consumed with
    thoughts that he was under surveillance and in danger; believed
    OCSD deputies were going to kill him; and made serious
    attempts at suicide. He also grew more distraught about his
    failed marriage.
    Four defense experts detailed Steskal’s family
    dysfunction, physical abuse from his parents and siblings,
    difficulties in school, drug use, and history of suicidal thinking,
    suspiciousness, and peculiar ideas. The defense psychiatrist,
    Dr. Roderick Pettis, concluded that Steskal suffered from
    chronic paranoia that had progressed to full-blown psychosis
    after the traffic stops by Deputy Spencer — Steskal went from
    feeling the police were following him to fearing they would kill
    him. Dr. Pettis testified that at the time of the crime, Steskal
    was in a psychotic state and suffering from a delusional
    4
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    disorder.
    B. Penalty Phase
    The prosecution presented evidence of an incident that
    occurred 19 years before the crime, in which Steskal
    intentionally drove his motorcycle at high speed toward a police
    officer who had stopped him for speeding. Steskal nearly hit the
    officer. Deputy Riches’s parents, Bruce and Meriel Riches,
    testified about their son’s hard work, his desire to help others,
    and how they responded to his death.
    The defense presented witnesses who described Steskal’s
    kindness to others and an additional expert who summarized
    Steskal’s background and testified that Steskal suffered from a
    delusional disorder, chronic depression, and schizotypal
    personality disorder, a personality disorder on a continuum with
    schizophrenia.
    The trial court declared a mistrial after the jury
    deadlocked 11 to one in favor of life without the possibility of
    parole.
    C. Penalty Retrial
    During the penalty retrial, the prosecution introduced
    much of the same evidence that was presented at the guilt
    phase. Witnesses described Steskal’s behavior just before the
    crime, at the 7-Eleven, and during his arrest. The prosecution
    presented new evidence to show that Steskal attempted to
    destroy the T-shirt he was wearing during the crime, as well as
    evidence that Steskal shaved his moustache immediately after
    the shooting. In addition to the first responders and criminalists
    from the sheriff’s department who had testified in the guilt
    phase, a paramedic testified for the first time about his efforts
    to save Deputy Riches’s life and the moment of his death. The
    5
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    pathologist described Deputy Riches’s injuries with the
    assistance of a life-sized mannequin that was pierced with rods
    to show the bullet wounds.
    The prosecution again introduced as aggravating evidence
    Steskal’s behavior during the motorcycle stop, as well as new
    evidence of his attempted escape from jail before the penalty
    retrial. The prosecution presented evidence that Steskal had
    accumulated contraband metal clippers and scraped away a
    portion of his cell wall that abutted a ventilation system leading
    to the roof of the jail. Steskal had also hidden strips of bedsheets
    in his mattress that were long enough to lower him from the roof
    of the jail to the street.
    The prosecution again introduced victim impact evidence
    from Deputy Riches’s parents, as well as testimony from Deputy
    Riches’s best friend and three colleagues from the sheriff’s
    department who described his positive outlook and loyalty. The
    witnesses conveyed the loss they and their families experienced
    when Deputy Riches was murdered.
    The defense also largely mirrored the guilt phase, with
    identical evidence depicting Steskal’s background, his
    deteriorating mental health, and expert opinions regarding his
    condition. Steskal’s brother and sister testified in greater detail
    about the physical and emotional abuse Steskal experienced in
    childhood and his suicide attempt at age 13. Acquaintances
    described his kindness; Steskal’s niece described him as a father
    figure who provided regular encouragement and support
    through correspondence from jail.
    On rebuttal, the prosecution presented testimony from
    three officers who interacted with Steskal while he was in jail
    awaiting the penalty retrial and who found no indication he
    6
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    experienced mental health problems. The prosecution also
    introduced evidence of an incident that took place 11 years
    before the crime, in which Steskal was driving erratically and
    dropping clear plastic bags out of his vehicle before an OCSD
    deputy stopped him. During the stop, Steskal appeared to be
    under the influence of drugs or alcohol, would not provide his
    name, and repeatedly yelled that he wanted the deputy to shoot
    him.
    II.    DISCUSSION
    A. Guilt Phase Issues
    1. Refusal to instruct the jury on voluntary
    manslaughter
    Steskal raises numerous claims of error. He first claims
    the trial court erred by denying his request to instruct the jury
    on voluntary manslaughter based on a theory of imperfect self-
    defense — that is, a theory that Steskal actually, though
    unreasonably, believed his life was in danger when he shot
    Deputy Riches. The trial court denied the request because the
    evidence did not support giving the instruction. We find no error
    in the court’s ruling.
    a. Background
    At trial, Steskal called several witnesses who described
    Steskal’s attitudes toward law enforcement and their causes,
    including, primarily, Steskal’s experiences during the two traffic
    stops conducted by Deputy Spencer. A retired Los Angeles
    Police Department tactics officer testified that Deputy Spencer’s
    arrest of Steskal after a traffic stop some months before the
    crime was highly unprofessional. During the stop, Deputy
    Spencer drew his gun on Steskal, cursed at and disparaged him,
    called additional officers to the scene, unfastened Steskal’s
    7
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    pants, and searched inside his underwear. Deputies wrestled
    Steskal to the ground when he began to protest the treatment.
    The second stop by Deputy Spencer occurred when Steskal
    allegedly failed to signal a turn, though there was some factual
    dispute as to whether the stop was justified on that ground; one
    witness claimed that Steskal had, in fact, signaled.
    Three witnesses saw Steskal in April 1999, soon after the
    second traffic stop. One testified that Steskal was nervous about
    being stopped by the police again; another found Steskal was
    very fearful of the police and convinced he was under
    surveillance; and the third recounted Steskal’s belief the police
    would kill him. A witness who saw Steskal in June, just before
    the crime, testified that Steskal was distraught about his failing
    marriage and continued to believe the police were following him.
    Dr. Roderick Pettis, the defense psychiatrist, testified that
    after the traffic stops, Steskal experienced psychotic delusions
    about being killed by law enforcement officers and withdrew to
    a camp in the mountains. Steskal was suicidal the day before
    the crime, when he had to return to town for legal proceedings
    related to his traffic stop. Dr. Pettis explained that Steskal’s
    screaming and banging at the apartment complex was evidence
    that his despair and stress had reached extreme levels. On
    cross-examination, Dr. Pettis acknowledged a report of
    statements from Steskal’s wife, who told investigators that
    immediately after the crime, Steskal exclaimed to her, “ ‘Oh, my
    God, what did I do, why did I do that?’ ” He confessed to shooting
    Deputy Riches, saying, “ ‘I don’t know why I shot him.’ ”
    Dr. Pettis testified that the report did not alter his opinion that
    Steskal was experiencing significant fear and distress before the
    shooting.
    8
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    A police psychologist described a “fight or flight” response,
    an automatic and sometimes unconscious reaction to danger.
    He explained such a response was more likely to occur in
    individuals who experience paranoia and could account for
    responses to fear that involved excessive violence.
    Based on this evidence, defense counsel requested that the
    trial court instruct the jury on voluntary manslaughter, as well
    as imperfect self-defense, on a theory that Steskal actually but
    unreasonably believed he had to shoot Deputy Riches in order
    to defend himself. The trial court denied the request on the
    ground that the evidence did not support giving the instruction.
    The court concluded that Steskal’s outburst at the apartment
    complex just before the shooting and his comments to the store
    clerk reflected anger rather than fear. Although there was
    evidence Steskal feared OCSD deputies generally, the court
    found no evidence he harbored a specific belief, real or imagined,
    that Deputy Riches posed an imminent threat at the time of the
    shooting, as would be required to establish imperfect self-
    defense. The court also found that by carrying a semiautomatic
    weapon into the 7-Eleven, Steskal himself created the
    circumstances of the shooting and was not entitled to invoke the
    doctrine of imperfect self-defense in any event.
    b. Discussion
    “A trial court must instruct on all lesser included offenses
    supported by substantial evidence.” (People v. Duff (2014) 
    58 Cal.4th 527
    , 561.) Although instruction on a lesser included
    offense “is not required when the evidence supporting such an
    instruction is weak” (People v. Vargas (2020) 
    9 Cal.5th 793
    , 827)
    or based on speculation (People v. Westerfield (2019) 
    6 Cal.5th 632
    , 718), it is required when the lesser included offense is
    9
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    supported by “ ‘evidence that a reasonable jury could find
    persuasive’ ” (People v. Lewis (2001) 
    25 Cal.4th 610
    , 645).
    “ ‘Doubts as to the sufficiency of the evidence to warrant
    instructions should be resolved in favor of the accused.’ ” (People
    v. Flannel (1979) 
    25 Cal.3d 668
    , 685; see also People v. Turner
    (1990) 
    50 Cal.3d 668
    , 690.) We review independently whether
    the trial court erred in rejecting an instruction on a lesser
    included offense. (People v. Booker (2011) 
    51 Cal.4th 141
    , 181.)
    Voluntary manslaughter — an unlawful killing without
    malice — is a lesser included offense of murder, an unlawful
    killing with malice aforethought. (People v. Booker, 
    supra,
     51
    Cal.4th at p. 181.) “Imperfect self-defense, which reduces
    murder to voluntary manslaughter, arises when a defendant
    acts in the actual but unreasonable belief that he is in imminent
    danger of death or great bodily injury.” (People v. Duff, supra,
    58 Cal.4th at p. 561.) “To satisfy the imminence requirement,
    ‘[f]ear of future harm — no matter how great the fear and no
    matter how great the likelihood of the harm — will not suffice.
    The defendant’s fear must be of imminent danger to life or great
    bodily injury.’ ” (People v. Trujeque (2015) 
    61 Cal.4th 227
    , 270.)
    Steskal argues that evidence of his delusional fear of
    OCSD deputies supported an inference that he perceived
    imminent danger when Deputy Riches arrived at the 7-Eleven.
    The Attorney General asserts that this claim is precluded by
    People v. Elmore (2014) 
    59 Cal.4th 121
    , in which we held that
    “purely delusional perceptions of threats to personal safety
    cannot be relied upon to claim unreasonable self-defense,” as
    opposed to claiming legal insanity. (Id. at pp. 138–139; see id.
    at p. 141.) Steskal counters that his perception was not “ ‘purely
    delusional’ ” (id. at p. 138) because he did accurately perceive
    that Deputy Riches was a law enforcement officer, though his
    10
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    reaction to that fact was distorted by mental illness. We need
    not resolve this debate because, as the trial court correctly
    concluded, the evidence provided no substantial support for a
    claim that Steskal acted out of any fear of imminent peril,
    whether delusional or not.
    Steskal did present evidence of his ongoing fear of law
    enforcement and the possibility he experienced a “fight or flight”
    response to seeing Deputy Riches in his vehicle. But while the
    jury could have inferred from this evidence that Steskal believed
    he was in some danger at the time of the killing, this evidence
    alone did not constitute substantial evidence that Steskal
    opened fire on the officer because he perceived him as posing “a
    risk of imminent peril” that could be met only through use of
    deadly force. (People v. Simon (2016) 
    1 Cal.5th 98
    , 133; see
    People v. Manriquez (2005) 
    37 Cal.4th 547
    , 582 [evidence that
    the “defendant may have harbored some fear of future harm”
    from the victim is insufficient to support an imperfect self-
    defense theory].) While “[t]he testimony of a single witness,
    including the defendant, can constitute substantial evidence” to
    support a voluntary manslaughter instruction (People v. Lewis,
    
    supra,
     25 Cal.4th at p. 646), none of the evidence here lent
    substantial support to a theory of imperfect self-defense; Steskal
    himself “did not testify, and there is no evidence he ever told
    anyone that he had acted out of fear” (Simon, at p. 134). His
    remarks immediately after the shooting offered no indication
    that he feared Deputy Riches at all, much less that he feared
    imminent harm, and he did not present other evidence to show
    what had motivated his actions.
    The circumstances of the crime indicated that Steskal
    “was the aggressor in the[] confrontation” with Deputy Riches,
    not the other way around. (People v. Simon, supra, 1 Cal.5th at
    11
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    p. 133.) Shortly before Steskal shot Deputy Riches, a witness
    heard him loudly cursing the world and, in response to an effort
    to calm him, proclaiming, “Fuck that, I have guns, I have
    ammunition.” Armed with a high-powered assault rifle, Steskal
    went to a nearby 7-Eleven that was a regular meeting place for
    OCSD deputies. Inside the store, Steskal flaunted the gun,
    asking the store clerk if she was afraid of it, and told her he
    carried it for protection against the “fucking law.” When Deputy
    Riches arrived, the clerk watched as Steskal strode without
    hesitation toward the patrol car and opened fire while Deputy
    Riches was still seated and before he had the opportunity to
    access his weapon. Steskal concedes there was no evidence
    Deputy Riches threatened him in any way.
    Without evidence that Steskal “possessed an actual but
    unreasonable belief of imminent danger of death or great bodily
    injury,” the trial court did not err as a matter of state law when
    it refused to give voluntary manslaughter instructions. (People
    v. Beck and Cruz (2019) 
    8 Cal.5th 548
    , 649.) Nor was there
    federal constitutional error, since “the constitutional
    requirement that capital juries be instructed on lesser included
    offenses extends only to those lesser included offenses supported
    by substantial evidence.” (People v. Duff, supra, 58 Cal.4th at
    p. 562.)
    2. Scope of expert testimony
    Steskal claims the trial court abused its discretion and
    violated his right to present a defense by sustaining the
    prosecution’s objections to three questions defense counsel posed
    to Dr. Pettis about events leading up to the crime. Steskal
    argues that he was entitled to present the excluded testimony
    as a basis for Dr. Pettis’s opinion under Evidence Code section
    12
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    802, which says a witness may provide “the reasons for his
    opinion and the matter . . . upon which it is based, unless he is
    precluded by law from using such reasons or matter as a basis
    for his opinion.” Steskal’s claim lacks merit.
    The first two questions defense counsel posed to Dr. Pettis
    asked him to relate (1) what Steskal said about having a
    “psychotic” reaction to messages on the radio the morning before
    the crime and (2) how Steskal described his behavior that day.
    The trial court sustained hearsay objections to both questions.
    We find no error in the court’s ruling.
    As we have recently explained, “[w]hen any expert relates
    to the jury case-specific out-of-court statements, and treats the
    content of those statements as true and accurate to support the
    expert’s opinion, the statements are hearsay.” (People v.
    Sanchez (2016) 
    63 Cal.4th 665
    , 686.) Dr. Pettis’s responses to
    the questions were inadmissible unless Steskal’s statements
    came within a hearsay exception. (Ibid.) Steskal did not invoke
    any such exception in the trial court, nor does he now invoke
    such an exception on appeal.
    Steskal instead asserts that Sanchez is inapplicable
    because the testimony concerned delusional beliefs rather than
    statements offered as “true and accurate.” (People v. Sanchez,
    supra, 63 Cal.4th at p. 686.) We reject this contention. The
    hearsay in question was not the content of the messages Steskal
    purportedly heard from the radio, but Steskal’s report that he
    heard such messages at all and experienced a “psychotic”
    reaction as a result. The defense sought to present this out-of-
    court description of Steskal’s distorted thinking, on which
    Dr. Pettis’s opinion had relied, as true and accurate. Such
    reliance on out-of-court statements, introduced through the
    13
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    medium of expert testimony, is precisely what Sanchez
    prohibits.
    Steskal also claims the trial court erred in sustaining
    objections to a third question: whether anything about Steskal’s
    behavior at the apartment complex in the “early morning hours”
    on the day of the crime caused Dr. Pettis to doubt that Steskal
    was experiencing a mental breakdown. The prosecutor objected
    that the question called for hearsay and referred to facts not in
    evidence. The trial court sustained the objection without
    comment.
    The neighbor who testified about Steskal’s behavior
    witnessed it at approximately midnight and the crime occurred
    just before 1:00 a.m. The question about Steskal’s behavior in
    the “early morning hours” therefore seemed to address behavior
    after the crime that was not in evidence and the related
    implication that Dr. Pettis had learned of it through out-of-court
    statements, proper bases for excluding the testimony. In
    subsequent questioning, it appeared that the defense simply
    misstated the timing and had been referring to the commotion
    Steskal caused at the apartment complex before the shooting.
    Defense counsel could have, but did not, offer any clarification
    in response to the prosecution’s objection.
    We conclude that the trial court did not abuse its
    discretion by sustaining prosecution objections to the three
    questions — particularly when Steskal “made no offer of proof
    at trial explaining why the witness should have been permitted
    to answer” them (People v. Lightsey (2012) 
    54 Cal.4th 668
    , 727)
    — and that the application of ordinary rules of evidence did not
    impermissibly interfere with Steskal’s constitutional right to
    present a defense (People v. O’Malley (2016) 
    62 Cal.4th 944
    ,

    995). Furthermore, if there had been error, we would conclude
    that it was harmless.
    Although Dr. Pettis was not allowed to detail Steskal’s
    description of having a “psychotic” reaction to the radio on the
    day of the crime, based on numerous other sources and
    anecdotes and Steskal’s lengthy history of mental illness
    Dr. Pettis testified at length about what he regarded as
    Steskal’s profound mental health crisis in the weeks, days,
    hours, and minutes before the shooting.              Among other
    conclusions, Dr. Pettis testified that Steskal was extremely
    paranoid and unable to process information properly; that he
    was terrified that he was going to be killed; and that he acted on
    bizarre delusions that he was being monitored. Although the
    trial court sustained one objection to testimony about Steskal’s
    behavior at the apartment complex, the defense was nonetheless
    able to question Dr. Pettis about it, eliciting Dr. Pettis’s opinion
    that it showed Steskal to be in “extreme despair,” delusional,
    and “very decompensated” just before the shooting. Under these
    circumstances, it is not reasonably probable that an outcome
    more favorable to Steskal would have resulted had the jury
    learned about one or two of Steskal’s postarrest statements that
    Dr. Pettis considered (People v. Watson (1956) 
    46 Cal.2d 818
    ,
    836), and any federal constitutional error would have been
    harmless beyond a reasonable doubt (Chapman v. California
    (1967) 
    386 U.S. 18
    , 24).
    3. Prosecutorial misconduct
    Steskal contends the prosecutor committed misconduct
    during his guilt phase closing argument by invoking sympathy
    for the victim, inviting the jury to draw an adverse inference
    from Steskal’s failure to call his wife as a witness, and arousing
    15
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    prejudice against Steskal. Steskal claims the argument violated
    both state law and his federal constitutional right to a fair trial.
    We conclude that no prejudicial misconduct occurred.
    a. Background
    During his guilt phase closing, the prosecutor argued that
    Deputy Riches saw Steskal in the 7-Eleven with a gun and was
    “a hero cop” for pulling up to the store with his lights flashing to
    respond to a potentially dangerous situation. A visual aid also
    listed “hero cop” in the overview of evidence for the jury. After
    the defense objected, the prosecutor explained his theory:
    Deputy Riches tried to draw Steskal out of the store by
    announcing his arrival, thus risking his life to ensure Steskal
    did not harm the store clerk. The trial court concluded the
    “hero” reference was not improper but ordered the prosecutor to
    explain that he was not seeking sympathy for Deputy Riches
    and to remove the visual aid as soon as he finished his
    presentation.
    The prosecutor prefaced his remaining remarks about
    Deputy Riches’s concern for the store clerk by stating: “This is
    about whether the defendant committed this crime. We are not
    talking about sympathy for Brad Riches. That’s not what this
    is about.” Instructions to the jury included CALJIC No. 1.00,
    which informed jurors they must not be influenced by sympathy,
    a point the defense highlighted in closing.
    The prosecutor also argued that Steskal drove off “like a
    coward” after shooting Deputy Riches. The defense objected to
    the characterization, arguing that the prosecutor had gone “over
    the top” arguing that Deputy Riches was a hero and had “just
    swung the pendulum down to the lower ends of the scale” by
    calling Steskal a coward. The court admonished the jury to
    16
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    disregard the term “coward” but rejected counsel’s request to
    advise the jury that the prosecutor had committed misconduct.
    During his rebuttal, the prosecutor commented on
    Steskal’s allegedly long history of paranoia and questioned why,
    when he had carried an assault rifle for protection for over a
    decade, he had not used it until the night he shot Deputy Riches.
    The prosecutor observed that the defense had not explained “the
    trigger of why that day, out of the 14 years, all of a sudden the
    defendant decided to act out.” Addressing this evidentiary gap,
    the prosecutor argued: “Now, the person that was perhaps the
    best witness to talk about the defendant before the murder and
    after the murder, who I can’t call because of the marital
    privilege, they don’t call. They don’t call Nannette Steskal.”
    Evidence established that Nannette and Steskal were
    married but separated and that she was dating other men.
    During the cross-examination of Dr. Pettis, the prosecutor
    highlighted some of the records Dr. Pettis considered, including
    those that showed Steskal confessed the crime to his wife, she
    was driving him to the mountains when OCSD deputies stopped
    them and arrested Steskal, and she later lied to investigating
    officers when questioned about the circumstances surrounding
    the crime.
    The defense objected to the prosecutor’s comment as
    “improper,” arguing that Nannette could assert a Fifth
    Amendment privilege against self-incrimination to avoid
    testifying. The prosecutor noted that Nannette was on Steskal’s
    witness list and countered that, because the statute of
    limitations on any charges against her had run, she had no
    privilege to assert. The trial court observed that the question of
    privilege could raise “other considerations,” notwithstanding
    17
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    any statute of limitations. The court explained: “I just don’t
    want to go into all this explanation with the jury as to the
    various possibilities, and I think that is fair because it is . . . a
    give or take, and there is [sic] some legal considerations the
    court is not prepared to make at this point in time.” The trial
    court then sustained the defense objection to any further
    comments about Nannette’s testimony but rejected a defense
    motion to strike the prosecutor’s remarks about the defense’s
    failure to call her as a witness.
    b. Discussion
    Under state law, “ ‘[a] prosecutor who uses deceptive or
    reprehensible methods to persuade the jury commits
    misconduct . . . .’ ” (People v. Friend (2009) 
    47 Cal.4th 1
    , 29.)
    Prosecutorial misconduct violates the federal Constitution when
    it results in a fundamentally unfair trial. (Ibid.) When a claim
    of misconduct is based on remarks to the jury, we consider
    whether there is a reasonable likelihood the jury construed the
    remarks in an improper fashion. (People v. Gonzales (2012) 
    54 Cal.4th 1234
    , 1275.)
    Steskal claims the prosecutor’s reference to Deputy Riches
    as a “hero” was “a blatant appeal for sympathy” that constituted
    misconduct. Our cases make clear that “[a]lthough a prosecutor
    may vigorously argue the case, appeals to sympathy for the
    victim during an objective determination of guilt fall outside the
    bounds of vigorous argument.” (People v. Amezcua and Flores
    (2019) 
    6 Cal.5th 886
    , 920.) The prosecutor’s argument did not
    cross this line, however. The prosecutor’s description of Deputy
    Riches was based on evidence of the conduct that led to his fatal
    confrontation with Steskal; it was “fair comment on the evidence
    and did not suggest ‘that emotion may reign over reason’ or
    18
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    invite ‘an irrational, purely subjective response.’ ” (People v.
    Seumanu (2015) 
    61 Cal.4th 1293
    , 1343.) In any event, there is
    no reasonable likelihood the characterization improperly
    inflamed the jury when the reference was brief, the prosecution
    and defense both informed the jury that sympathy for Deputy
    Riches was not relevant, and the trial court instructed the jury
    that sympathy was an inappropriate consideration. (People v.
    Daveggio and Michaud (2018) 
    4 Cal.5th 790
    , 857.)
    Steskal also contends the prosecutor committed
    misconduct by commenting on the defense’s failure to call
    Nannette as a witness. He asserts that any comment that
    invites a jury to draw an adverse inference from the defendant’s
    failure to call a witness violates federal due process protections
    because it undermines the presumption of innocence and
    ignores the variety of reasons a party may have for not calling a
    witness despite his or her ability to provide favorable testimony.
    He further claims that it was misconduct to comment on the
    failure to call Nannette because she could have refused to testify
    by invoking a marital communications privilege under Evidence
    Code section 980. Steskal did not raise these arguments in the
    trial court, and he has not established it would have been futile
    to do so. He has therefore forfeited them. We find no grounds
    for reversal in any event.
    We have long held that a prosecutor may make
    “ ‘comments based upon the state of the evidence or upon the
    failure of the defense to introduce material evidence or to call
    anticipated witnesses.’ ” (People v. Gomez (2018) 
    6 Cal.5th 243
    ,
    299; see, e.g., People v. Gonzales, supra, 54 Cal.4th at p. 1275
    [“it is neither unusual nor improper to comment on the failure
    to call logical witnesses”]; People v. Szeto (1981) 
    29 Cal.3d 20
    ,
    34.) Steskal acknowledges this authority but urges us to follow
    19
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    what he characterizes as “the trend of the law . . . to
    substantially narrow the circumstances under which a
    prosecutor can comment on a defendant’s failure to call a
    particular witness.”
    Steskal points to various out-of-state cases, which he
    argues stand for two primary propositions. First, a jury should
    not be invited to draw an adverse inference from the defendant’s
    failure to call particular witnesses when that inference “would
    favor the State in a factual dispute over an element of the crime
    on which the State clearly bears the burden of proof.” (State v.
    Hill (2009) 
    199 N.J. 545
    , 565 [
    974 A.2d 403
    , 416] [prohibiting
    jury instruction]; Jackson v. State (Fla. 1991) 
    575 So.2d 181
    , 188
    [error to allow reference in closing argument].) Second, an
    inference regarding the content of testimony that has not been
    offered presents “dangers of speculation and conjecture” (State
    v. Brewer (Me. 1985) 
    505 A.2d 774
    , 776), particularly
    considering that “ ‘questions of demeanor and credibility,
    hostility, and the like may influence the [party] not to produce a
    witness whose testimony might be entirely harmful to the [other
    party]’ ” (State v. Tahair (2001) 
    172 Vt. 101
    , 108 [
    772 A.2d 1079
    ,
    1085]).
    Our cases have acknowledged the same concerns. We
    have explained that “a rule permitting comment on a
    defendant’s failure to call witnesses is subject to criticism if
    applied when the reason for his failure to do so is ambiguous, or
    if the defendant is simply standing on his right to have the state
    prove his guilt,” and that a trial court may disallow such
    comment for these reasons. (People v. Ford (1988) 
    45 Cal.3d 431
    ,
    447.) Our cases also recognize that “[a] distinction clearly exists
    between the permissible comment that a defendant has not
    produced any evidence, and . . . an improper statement that a
    20
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    defendant has a duty or burden to produce evidence, or a duty
    or burden to prove his or her innocence.” (People v. Bradford
    (1997) 
    15 Cal.4th 1229
    , 1340; see People v. Bennett (2009) 
    45 Cal.4th 577
    , 596 [comments do not impermissibly shift the
    burden of proof when the prosecutor does not “state or imply
    that defendant had a duty to produce evidence”].)
    To the extent Steskal asks us to further delineate the
    bounds of proper comment on the defendant’s failure to present
    certain witnesses, this case does not present an appropriate
    occasion to do so. Steskal largely secured at trial the limitation
    he now seeks on appeal. Once the prosecutor made reference to
    Nannette’s absence from trial, the trial court sustained Steskal’s
    objection and prevented the prosecutor from making any further
    references. The court did so before the prosecutor could argue
    that the omission of Nannette’s testimony justified an adverse
    inference.
    Furthermore, even if the prosecutor’s solitary reference to
    Nannette’s absence from trial was improper — whether due to
    general concerns about such comments or the possibility
    Nannette could have invoked marital privilege to avoid
    testifying — there is no reasonable likelihood the jury construed
    the reference in an objectionable fashion. (People v. Gonzales,
    supra, 54 Cal.4th at p. 1275.) We consider the remarks in the
    context of the argument as a whole and “ ‘ “do not lightly infer”
    that the jury drew the most damaging rather than the least
    damaging meaning from the prosecutor’s statements.’ ” (People
    v. Covarrubias (2016) 
    1 Cal.5th 838
    , 894.) Although the jury
    could have understood the prosecutor’s comment to imply that
    Nannette would undermine Steskal’s mental state defense, the
    jury was aware of “equally plausible” reasons for her failure to
    testify (People v. Ford, supra, 45 Cal.3d at p. 445): She had been
    21
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    separated from Steskal, involved in his efforts to evade law
    enforcement after the shooting, and dishonest when questioned
    about Steskal’s actions before and after the crime. Under these
    circumstances, jurors could conclude that estrangement,
    credibility issues, or Nannette’s own legal troubles explained
    her absence from trial. “Despite the prosecutor’s brief remark,
    the jury was capable of deciding, as a matter of common sense,
    whether [she] was a logical or reliable witness.” (People v.
    Gonzalez (1990) 
    51 Cal.3d 1179
    , 1216.)
    Moreover, however the jury may have understood it, the
    prosecutor’s reference to Nannette’s absence “was tangential in
    any event.” (People v. Gonzalez, supra, 51 Cal.3d at p. 1216.)
    The prosecution did not dispute the key elements of Steskal’s
    defense — that he suffered from mental illness that caused him
    to fear law enforcement officers. Instead, the prosecution
    argued that any fear Steskal experienced did not negate
    premeditation and deliberation: “[I]n fact, if you think about
    someone who is fearing a situation and wants to prepare to meet
    that fear, wants to protect themselves, if that’s truly what they
    are feeling[,] . . . that person is going to premeditate and
    deliberate more than anybody else.” The prosecution pointed to
    evidence that Steskal was cursing and yelling just before leaving
    for the 7-Eleven, took an assault rifle with him to the store, told
    the store clerk seconds before the shooting that he intended to
    use his gun to protect himself against the “fucking law,” and
    launched an attack on Deputy Riches the moment he arrived.
    As the prosecutor argued, fearful or not, Steskal appeared to be
    “a man who has a plan to do something. To provoke, or if
    provoked, to respond.” This evidence was far more damaging
    than any inference the jury might have drawn about the
    likelihood that Nannette’s testimony would be unhelpful to
    22
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Steskal’s mental state defense. Thus, even if the prosecutor’s
    observation about Nannette’s failure to testify were considered
    misconduct, we would find no prejudice, particularly when the
    comment was brief, “defendant’s objection was immediately
    sustained . . . and the prosecutor did not return to the subject.”
    (People v. Bennett, 
    supra,
     45 Cal.4th at p. 613; see People v.
    Ghobrial (2018) 
    5 Cal.5th 250
    , 289.)
    Finally, Steskal contends the prosecutor appealed to the
    passion and prejudice of the jury when he referred to Steskal
    driving off “like a coward.” Steskal asserts that this comment,
    when combined with the description of Deputy Riches as a hero
    and comment on Nannette’s failure to testify, established a
    pattern of misconduct that violated his federal constitutional
    rights and deprived him of a fair trial. We are not persuaded.
    “[T]he use of derogatory epithets to describe a defendant is not
    necessarily misconduct” where, as here, “[t]he prosecutor’s
    remarks . . . were founded on evidence in the record and fell
    within the permissible bounds of argument.” (People v. Friend,
    
    supra,
     47 Cal.4th at p. 32.) In any event, the trial court
    admonished the jury to disregard the “coward” reference and we
    “presume the jury heeded the admonition and that any error
    was cured.” (People v. Dickey (2005) 
    35 Cal.4th 884
    , 914.) Given
    this resolution, we find no prejudicial misconduct, nor do we
    discern any pattern of misconduct that could have affected the
    fairness of Steskal’s trial or otherwise violate his federal
    constitutional rights.
    4. Jury view of Deputy Riches’s patrol car
    Steskal contends the trial court erred by allowing a jury
    view of Deputy Riches’s patrol car and asserts the evidence was
    so inflammatory it denied him a fair trial. We find no error.
    23
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    a. Background
    Before trial, the prosecution moved to allow the jury to
    view the patrol car and to have the car transported to the
    courthouse for this purpose. The defense opposed the motion,
    arguing that allowing the jury to view the patrol car, which was
    riddled with bullet holes, was more prejudicial than probative
    under Evidence Code section 352. Defense counsel stated, “I
    can’t imagine anyone viewing that patrol car not gasping and
    not being overwhelmed with a whole variety of emotions. It is
    really a horrible sight.” Steskal did not dispute the facts a jury
    view would highlight: He fired 30 rounds into the patrol car
    from close range as Deputy Riches sat trapped inside. The
    prosecution added that seeing the vehicle would allow the jury
    to appreciate where the bullets struck in relation to Deputy
    Riches’s position. Overruling the defense objection, the trial
    court concluded that when defendant was the person who “blew
    up the car,” there was no reason the jury should not see it; “[i]t
    is not like looking at Deputy Riches’ body. We are keeping out
    most of those photographs.”
    Steskal moved for reconsideration. After viewing the
    patrol car, the trial court denied the motion, stating: “I think it
    is extremely probative. Certainly, probative value outweighs
    any prejudicial effect. . . . I think [it does] nothing but assists
    the trier of fact as far as the position of the defendant and the
    position of the victim.”
    At trial, after the prosecutor marked a number of
    photographs of the patrol car he intended to introduce, the
    defense renewed its objection to the jury view of the car as
    cumulative of the photographs. The trial court again overruled
    the objection, observing that most of the photographs only
    24
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    showed a portion of the vehicle and those showing the entire car
    were from a higher angle than a person would get standing in
    front of the car — “seeing the car is not only more probative than
    cumulative, but very beneficial to the trier of fact, because it
    gives you the perspective of the shooter and the victim that you
    don’t get looking at the photographs.” The jury later viewed the
    patrol car for six minutes on court premises.
    The prosecution also introduced photographs of the patrol
    car showing some of the bullet holes in the hood and windshield,
    the shattered driver’s window, closeup images of damage to the
    interior, and a view of the vehicle from a distance. In addition,
    the prosecution played surveillance videotapes that recorded
    events from inside the 7-Eleven, capturing the sound of
    gunshots after Steskal left the store and a distant glimpse of the
    shooting. The prosecution also presented the testimony of
    witnesses including a 7-Eleven employee who saw Steskal
    walking close to the patrol car as he fired his rifle; first
    responders who described finding Deputy Riches; a criminalist
    who collected evidence and attempted to determine the
    trajectory of shots; and a pathologist who described Deputy
    Riches’s wounds. A photograph showing Deputy Riches’s body
    at the hospital further revealed the extent of some of his
    injuries.
    b. Discussion
    “The trial court may allow the jury to ‘view the place in
    which the offense is charged to have been committed, or in which
    any other material fact occurred.’ ([Pen. Code, ]§ 1119.) We
    review for abuse of discretion a trial court’s ruling on a party’s
    motion for a jury view.” (People v. Davis (2009) 
    46 Cal.4th 539
    ,
    610.)
    25
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Evidence Code section 352 “permits the court to exclude
    otherwise relevant evidence if its probative value is
    substantially outweighed by the probability that its admission
    will create a substantial danger of undue prejudice.” (People v.
    Powell (2018) 
    5 Cal.5th 921
    , 961.) “During the guilt phase, there
    is a legitimate concern that crime scene [evidence] can produce
    a visceral response that unfairly tempts jurors to find the
    defendant guilty of the charged crimes.” (People v. Box (2000)
    
    23 Cal.4th 1153
    , 1201, disapproved on another ground in People
    v. Martinez (2010) 
    47 Cal.4th 911
    , 948, fn. 10.) However, “[s]o
    long as the probative value of graphic or disturbing material is
    not substantially outweighed by its prejudicial effects, a
    prosecutor is entitled to use such evidence to ‘present a
    persuasive and forceful case.’ ” (People v. Merriman (2014) 
    60 Cal.4th 1
    , 80; see People v. Fayed (2020) 
    9 Cal.5th 147
    , 196
    [prosecution entitled to present “ ‘ “grim” ’ ” evidence of violent
    crime]; People v. Booker, 
    supra,
     51 Cal.4th at p. 171 [prosecution
    “is not required to sanitize its evidence”].)
    Steskal claims the patrol car did not have substantial
    probative value because it did not address disputed issues. A
    defendant, however, “cannot prevent the admission of relevant
    evidence by claiming not to dispute a fact the prosecution is
    required to prove beyond a reasonable doubt. The jury was
    entitled to learn that the physical evidence . . . supports the
    prosecution’s theory of the case.” (People v. Rountree (2013) 
    56 Cal.4th 823
    , 852; see People v. Cowan (2010) 
    50 Cal.4th 401
    , 476
    [“defendant’s not guilty plea put in issue all of the elements of
    the charged offenses, including the elements he conceded”].)
    As evidence of the volume and aim of shots directed at
    Deputy Riches from close range, the patrol car was “highly
    relevant to show the manner in which the [victim was] killed”
    26
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    (People v. Ramirez (2006) 
    39 Cal.4th 398
    , 453; see People v.
    Brasure (2008) 
    42 Cal.4th 1037
    , 1054), to “illustrate and
    corroborate the testimony given by [witnesses] regarding the
    circumstances of the crime” (People v. Scheid (1997) 
    16 Cal.4th 1
    , 18), and to support the conclusion that the killing was
    deliberate (People v. Booker, 
    supra,
     51 Cal.4th at p. 171; People
    v. Riggs (2008) 
    44 Cal.4th 248
    , 304; cf. People v. Salazar (2016)
    
    63 Cal.4th 214
    , 245 [multiple gunshots at close range supported
    theory of premeditation and deliberation]; People v. Gonzales
    and Soliz (2011) 
    52 Cal.4th 254
    , 295 [same]).
    Steskal contends the patrol car also lacked probative value
    because it was cumulative of the photographs, videotapes, and
    witness testimony before the jury. But as the trial court
    observed, viewing the patrol car in person afforded a perspective
    not evident in the photographs, which showed only portions of
    the vehicle. The same is true of the videotapes and eyewitness
    testimony. The prosecutor was not required to rely solely on
    those pieces of evidence when viewing the vehicle “would
    enhance the jury’s understanding of the issues.” (People v.
    Cowan, 
    supra,
     50 Cal.4th at p. 476; see People v. Brasure, 
    supra,
    42 Cal.4th at p. 1054.)
    Steskal claims the jury view was unduly prejudicial
    because it had the emotional impact of “a death scene” strewn
    with bullet holes, shattered glass, and torn, blood-soaked fabric.
    The prejudice with which Evidence Code section 352 is
    concerned, however, is not damage to a defense that is caused
    by relevant, noncumulative, and highly probative evidence.
    (People v. Doolin (2009) 
    45 Cal.4th 390
    , 439.) Graphic evidence
    in a murder case is always disturbing (People v. Thomas (2012)
    
    53 Cal.4th 771
    , 807) but it is not inadmissible simply because it
    is unpleasant to view (see, e.g., People v. Fayed, supra, 
    9 Cal.5th 27
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    at p. 196 [victim’s blood-soaked shirt and pants]; Thomas, at
    p. 805 [victims’ clothing stained with blood and tissue]; People v.
    Riggs, supra, 44 Cal.4th at p. 303 [crime scene and autopsy
    photographs of victim]; People v. Brasure, 
    supra,
     42 Cal.4th at
    pp. 1053–1054 [photographs of victim’s decomposing and
    tortured body]; People v. Lewis, 
    supra,
     25 Cal.4th at p. 642
    [photographs and videotape showing victims in blood-splattered
    surroundings]). “ ‘The jury can, and must, be shielded from
    depictions that sensationalize an alleged crime, or are
    unnecessarily gruesome, but the jury cannot be shielded from
    an accurate depiction of the charged crimes that does not
    unnecessarily play upon the emotions of the jurors.’ ” (People v.
    Streeter (2012) 
    54 Cal.4th 205
    , 238.)
    Steskal does not claim that viewing the patrol car exposed
    the jury to any “sensationalized illustrations of a crime” (People
    v. Zambrano (2007) 
    41 Cal.4th 1082
    , 1150) or “gratuitous
    details” unrelated to his actions (People v. Caro (2019) 
    7 Cal.5th 463
    , 503). “ ‘We will not disturb a trial court’s exercise of
    discretion under Evidence Code section 352 “ ‘except on a
    showing that the court exercised its discretion in an arbitrary,
    capricious or patently absurd manner that resulted in a
    manifest miscarriage of justice.’ ” ’ ” (People v. Mora and Rangel
    (2018) 
    5 Cal.5th 442
    , 480.) The trial court’s reasoned decision
    to allow a jury view of the patrol car was not an abuse of this
    discretion. (See People v. Spencer (2018) 
    5 Cal.5th 642
    , 681 [trial
    court is better able to assess prejudice from the display of
    physical evidence].)
    Steskal also claims that the jury view of the patrol car
    violated his federal due process rights, arguing that it was
    inherently    inflammatory    and     had   no    substantial,
    noncumulative probative value. Although the Attorney General
    28
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    argues that Steskal forfeited his due process argument by
    failing to object on that basis at trial, we have reached an
    asserted due process violation when it was based on the same
    theory of exclusion set forth under Evidence Code section 352.
    (People v. Partida (2005) 
    37 Cal.4th 428
    , 438–439.) But
    Steskal’s claim fails on the merits. “ ‘The admission of relevant
    evidence will not offend due process unless the evidence is so
    prejudicial as to render the defendant’s trial fundamentally
    unfair.’ ” (People v. Jablonski (2006) 
    37 Cal.4th 774
    , 805.) The
    jury view of the patrol car did not have such an effect on
    Steskal’s trial.
    5. Cumulative error
    Steskal argues that even if harmless in isolation, the guilt
    phase errors he asserts were cumulatively prejudicial.
    Discussing the prosecutor’s reference to Nannette’s absence
    from trial, we explained that even if prosecutorial misconduct
    occurred it was not prejudicial. As we have found no other
    errors, there is no cumulative prejudice that could have denied
    Steskal a fair trial.
    B. Penalty Retrial Issues
    1. Admission of impeachment testimony
    Steskal contends the trial court abused its discretion when
    it allowed the prosecution to reference the facts of other death
    penalty cases during the cross-examination of defense
    psychiatrist Dr. Pettis at the penalty retrial. We reject this
    claim.
    In cross-examining Dr. Pettis, the prosecutor asked him
    about two prior death penalty cases in which he had testified for
    the defense. Dr. Pettis testified that his role in the first case had
    been to evaluate whether the defendant was competent to be
    29
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    executed. When the prosecutor referenced the fact that the
    defendant in that case had been convicted of raping and
    murdering two women, Dr. Pettis indicated that he did not
    recall the crime but confirmed he had concluded the defendant
    lacked mental competence to be executed. When the prosecutor
    asked whether he was biased against the death penalty,
    Dr. Pettis responded that he was not. The prosecutor then
    observed that the defendant in the second case was convicted of
    raping a woman and setting her on fire. Dr. Pettis testified
    regarding his conclusion that the second defendant suffered
    from mental illness at the time of his crimes.
    The defense objected to the first exchange on relevance
    grounds. Later, outside the presence of the jury, defense counsel
    argued that allowing the jury to hear about the crimes in
    Dr. Pettis’s prior cases served no purpose but to suggest that
    “this guy will get on the stand in any horrific case and testify for
    the defense.” The trial court overruled defense objections based
    on relevance and Evidence Code section 352. But it advised the
    prosecution to keep any similar questioning brief because “the
    weighing process leans more towards prejudicial.” Steskal
    contends it was error for the trial court to permit the questioning
    at all.
    “It is settled that the trial court is given wide discretion in
    controlling the scope of relevant cross-examination.” (People v.
    Farnam (2002) 
    28 Cal.4th 107
    , 187.) “ ‘[T]he scope of cross-
    examination of an expert witness is especially broad . . . .’ ”
    (People v. DeHoyos (2013) 
    57 Cal.4th 79
    , 123; see Evid. Code,
    § 721, subd. (a).) “The prosecutor may properly cross-examine a
    witness to show bias, prejudice, interest, hostility or friendship
    toward a party that would bear on the question of the credibility
    of the witness. [Citations.] An expert’s testimony in prior cases
    30
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    involving similar issues is a legitimate subject of cross-
    examination when it is relevant to the bias of the witness.”
    (DeHoyos, at p. 123.) A “witness’s personal philosophical
    opposition to the death penalty is relevant to his credibility.”
    (People v. Bennett, 
    supra,
     45 Cal.4th at p. 606.)
    A prosecutor may refresh an expert’s recollection of prior
    matters “by providing a brief recitation of their salient facts,” to
    allow the expert an opportunity to defend past conclusions.
    (People v. Shazier (2014) 
    60 Cal.4th 109
    , 137.) In Shazier, we
    concluded that the prosecutor did not commit misconduct by
    reciting potentially inflammatory facts from prior cases
    involving sexually violent predators when it was an “effort to
    attack the validity of [the expert’s] opinions in the other cases.”
    (Id. at p. 139.) Similarly, in People v. Zambrano, 
    supra,
     
    41 Cal.4th 1082
    , we observed that it was permissible for the
    prosecutor to challenge an expert on prison adjustment by
    referencing the facts of a prior case in which the expert found
    the defendant posed no safety risk in prison though convicted of
    four murders and six attempted murders. (Id. at pp. 1164–
    1165.) There, we noted that “[t]he prosecutor was entitled to
    expose bias in the witness by showing his propensity to advocate
    for criminal defendants even in extreme cases.” (Id. at p. 1165.)
    Here, by contrast, the prosecution inquiry was limited to
    showing that Dr. Pettis made mental health findings favorable
    to the defense in two prior death penalty cases involving
    particularly horrifying crimes. The facts of the prior cases were
    relevant neither to the validity of Dr. Pettis’s conclusions in
    those matters, as was the case in Shazier, nor to any potential
    bias in his findings, as in Zambrano. Instead, the prosecutor’s
    questioning tended to imply that Dr. Pettis’s willingness to
    testify for the defense in cases involving such crimes, without
    31
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    more, reflected a bias against the death penalty.
    Assuming for the sake of argument that the questions
    were improper, we conclude that they were harmless. The
    prosecutor’s reference to other case facts was brief, Dr. Pettis
    testified that he was not biased against the death penalty, and
    the impact of the questioning was minimal given the
    prosecutor’s extensive and detailed cross-examination of
    Dr. Pettis’s findings, which spanned four days.
    2. Prosecutorial misconduct
    Steskal contends the prosecutor committed misconduct in
    his closing argument at the penalty retrial, violating state law
    and federal due process protections. We conclude that no
    misconduct occurred.
    Steskal first claims there were two instances in which the
    prosecutor argued that Dr. Pettis’s testimony concerning
    mitigating factors was in fact aggravating. Citing evidence
    admitted under Penal Code section 190.3, factor (b), that Steskal
    had a weapon in his jail cell, the prosecutor remarked on
    Steskal’s dangerousness in custody: “Do you think for a moment
    that the defendant wouldn’t use that? Look back at Dr. Pettis’[s]
    testimony . . . . He said the defendant is very mild and meek . . .
    except when he is into this delusion thing, and then he just goes
    all out of control . . . . [¶] So if you tend to believe this . . . you
    have a person right now that is capable and willing to kill
    someone in authority.” Later, when discussing mitigating
    factors, the prosecutor noted that “a lack of mitigation in those
    factors does not mean aggravation. But there are things that
    you can consider in mitigation that would reduce mitigation.”
    The prosecutor argued that “if Dr. Pettis has some credibility
    with you, you may want to look at this part of his testimony,
    32
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    where he is saying that the defendant . . . when he gets
    confronted with authority figures, you see what happens. [¶]
    That would be less than mitigating, if that is in fact true.”
    Preliminarily, the Attorney General asserts that Steskal
    failed to preserve his claim. Defense counsel raised his
    objections in a motion for mistrial the day after the prosecutor’s
    argument and before the defense had completed its closing
    remarks. “ ‘ “It is now well settled that an appellate court will
    not consider a claim as to the misconduct of counsel in argument
    unless objection is so made.” [Citation.] “The reason for this
    rule, of course, is that ‘the trial court should be given an
    opportunity to correct the abuse and thus, if possible, prevent by
    suitable instructions the harmful effect upon the minds of the
    jury.’ ” ’ ” (People v. Peoples (2016) 
    62 Cal.4th 718
    , 801.) We
    have explained that when a defendant’s objections to
    prosecution statements in a motion for mistrial are “specific
    enough for the trial court to craft suitable corrective
    instructions” and are made before the end of closing argument,
    “thus providing the trial court with an opportunity to admonish
    the jury prior to the start of deliberations,” the challenge may
    be preserved. (Ibid.) Though the form and timing of Steskal’s
    objection may not have been “ideal” (ibid.), Steskal’s motion for
    mistrial was sufficient to preserve the claim.
    Turning to the merits, we first consider Steskal’s claim
    that the prosecutor improperly urged the jury to consider
    mitigating evidence as aggravating when he discussed Steskal’s
    possession of weapons in jail, saying that Dr. Pettis’s testimony,
    if believed, tended to show Steskal would be “capable and willing
    to kill someone” while incarcerated. In People v. Edelbacher
    (1989) 
    47 Cal.3d 983
    , we held that evidence of a defendant’s
    character and background is admissible under Penal Code
    33
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    section 190.3, factor (k), “only to extenuate the gravity of the
    crime; it cannot be used as a factor in aggravation.”
    (Edelbacher, at p. 1033.) We later explained that a prosecutor
    may present “evidence of mental illness” in aggravation if it
    “relates to an aggravating factor listed in section 190.3”; that is
    so “even if it also bears upon a mitigating factor listed in that
    section.” (People v. Smith (2005) 
    35 Cal.4th 334
    , 356.) Thus,
    although “general evidence regarding a defendant’s mental
    state” may not be characterized as aggravating, mental state
    evidence may be considered in aggravation if, for example, it
    represents “specific evidence of the motivation behind the
    killing” and therefore is “relevant as a circumstance of the
    crime.” (Id. at p. 355; see People v. Nelson (2011) 
    51 Cal.4th 198
    ,
    224 [“ ‘[e]vidence that reflects directly on the defendant’s state
    of mind contemporaneous with the capital murder is relevant
    under section 190.3, factor (a)’ ”].) It is not improper for a jury
    to consider evidence of the defendant’s mental disorder in
    aggravation when it is not “strictly mitigating,” but instead
    relates to the circumstances of the crime or another factor in
    aggravation. (People v. Krebs (2019) 
    8 Cal.5th 265
    , 349.)
    Here, the prosecutor highlighted a circumstance of the
    crime — Steskal’s asserted reason for killing Deputy Riches —
    as relevant to his future dangerousness toward correctional
    staff.   We have observed that state of mind evidence
    “ ‘demonstrating [the defendant’s] attitude toward his victims
    [is] highly probative’ on the issue of future dangerousness.”
    (People v. Winbush (2017) 
    2 Cal.5th 402
    , 477; see People v. Rich
    (1988) 
    45 Cal.3d 1036
    , 1123 [future dangerousness argument
    may be based on circumstances of the crime].) And “ ‘[w]e have
    repeatedly declined to find error or misconduct where argument
    concerning a defendant’s future dangerousness in custody is
    34
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    based on evidence of his past violent crimes admitted under one
    of the specific aggravating categories of [Penal Code] section
    190.3.’ ” (People v. Tully (2012) 
    54 Cal.4th 952
    , 1046.) The
    prosecutor did not commit misconduct by urging the jury to
    consider the potential danger Steskal posed to correctional staff
    in light of his possession of weapons admitted under Penal Code
    section 190.3, factor (b) and the delusional mistrust of authority
    he had asserted to explain the circumstances of his crime.
    Steskal’s objection to the prosecutor’s argument that
    Steskal’s asserted delusional overreaction to authority was “less
    than mitigating” also lacks merit. This was not an argument
    that the jury should consider mitigating defense evidence in
    aggravation, but that Steskal’s mitigating evidence did not carry
    weight.    “ ‘ “ ‘A prosecutor does not mischaracterize such
    evidence [offered in mitigation] by arguing it should not carry
    any extenuating weight when evaluated in a broader factual
    context. We have consistently declined to criticize advocacy of
    this nature.’ ” ’ ”    (People v. Weaver (2012) 
    53 Cal.4th 1056
    ,
    1087.)
    Steskal also claims the prosecutor committed misconduct
    in the course of arguing that the jury should discount defense
    expert testimony.      When cross-examining Dr. Pettis, the
    prosecutor referenced a report in which Nannette claimed that
    Steskal told her what to say if she were questioned by the police.
    Dr. Pettis acknowledged that Nannette later lied when she was
    interviewed by investigating officers. She falsely said that she
    did not see Steskal take his gun to the 7-Eleven or come back
    with it, gave an excuse for Steskal deciding to shave his
    mustache immediately after the shooting, claimed that Steskal
    did not tell her what had happened, and denied knowing that
    Steskal put a gun in her car before she drove him away from the
    35
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    apartment. Dr. Pettis testified that it was “conceivable” that
    Steskal and his wife had made an agreement to lie to the police.
    In closing, the prosecutor argued that defense expert
    opinions were based on unreliable information. Overruling a
    defense objection to one such characterization, the trial court
    informed the jury: “[T]he lawyers are arguing what they
    perceive to be the facts. They are probably also going to argue
    inferences from these facts as they perceive them. You get to
    decide the facts, not the lawyers. So if they say something that
    may appear to be inconsistent with your recollection, it is your
    recollection that, obviously, you rely on and is important.”
    Moments later, the prosecutor argued that Dr. Pettis had relied
    on Nannette’s OCSD interviews even though they were
    “[r]eplete with lies” that she and Steskal had concocted to cover
    up the crime. The defense objected on the ground that the
    argument was based on a fact not in evidence, but the trial court
    overruled the objection. Steskal now contends the prosecutor
    committed misconduct by arguing that Nannette and Steskal
    had entered an agreement to cover up the crime.
    The Attorney General argues that Steskal forfeited his
    claim by failing to specifically cite misconduct and request an
    admonition. We will assume, for the sake of argument, that
    Steskal’s objection was sufficient to preserve the issue for
    appeal. (See People v. Pearson (2013) 
    56 Cal.4th 393
    , 434.) We
    find no misconduct. “ ‘The prosecution is given wide latitude
    during closing argument to make fair comment on the evidence,
    including reasonable inferences or deductions to be drawn from
    it.’ ” (People v. Seumanu, supra, 61 Cal.4th at p. 1363.) Given
    Dr. Pettis’s testimony acknowledging the possibility of planned
    deception, the prosecutor could ask the jury to infer that Steskal
    and his wife agreed on her fabrications to the sheriff’s
    36
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    department. “It was a matter for the jury to decide whether the
    inference was faulty or illogical and . . . the court repeatedly
    reminded the jurors that argument was not evidence.” (People
    v. Tully, supra, 54 Cal.4th at p. 1044.)
    3. Admission of evidence depicting the victim and
    crime scene
    Steskal contends that prosecution evidence illustrating
    the circumstances of the crime — a mannequin depicting
    Deputy Riches, photographs and a jury view of Deputy Riches’s
    patrol car, and autopsy photographs — was unduly prejudicial,
    and therefore should have been excluded under Evidence Code
    section 352. He further contends that the admission of this
    evidence violated his federal constitutional rights to due process
    and a reliable penalty trial. We conclude that the trial court did
    not abuse its discretion in admitting the evidence and that no
    federal constitutional violation occurred.
    Again, “ ‘[p]rejudice’ in the context of Evidence Code
    section 352 is not synonymous with ‘damaging’: it refers to
    evidence that poses an intolerable risk to the fairness of the
    proceedings or reliability of the outcome.” (People v. Booker,
    
    supra,
     51 Cal.4th at p. 188.) “[T]he court’s discretion under
    Evidence Code section 352 to exclude evidence showing
    circumstances of the crime ‘is much narrower at the penalty
    phase than at the guilt phase. This is so because the prosecution
    has the right to establish the circumstances of the crime,
    including its gruesome consequences ([Pen. Code, ]§ 190.3,
    factor (a)), and because the risk of an improper guilt finding
    based on visceral reactions is no longer present.’ [Citations.] At
    the penalty phase, the jury ‘is expected to subjectively weigh the
    evidence, and the prosecution is entitled to place the capital
    offense and the offender in a morally bad light.’ ” (People v. Bell
    37
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    (2019) 
    7 Cal.5th 70
    , 105–106.) The trial court retains “its
    traditional discretion to exclude ‘particular items of evidence’ by
    which the prosecution seeks to demonstrate either the
    circumstances of the crime (factor (a)), or violent criminal
    activity (factor (b)), in a ‘manner’ that is misleading, cumulative,
    or unduly inflammatory.” (People v. Box, supra, 23 Cal.4th at
    p. 1201.)
    a. Mannequin depicting Deputy Riches
    At the penalty retrial, Steskal objected to the introduction
    of a life-sized mannequin dressed in Deputy Riches’s bloody
    uniform. There was vomit on the front shirt pocket and the
    dried blood blended in with the color of the uniform, which was
    dark green. Rods placed in the mannequin reflected the location
    and trajectory of bullet wounds. Ruling that the mannequin was
    admissible, the trial court observed that it was not going to
    “shock anybody’s sensibilities.” The prosecutor referred to the
    mannequin during the pathologist’s testimony to show the
    location of each wound as he described them. During his closing
    argument, the prosecutor brought the mannequin out to show
    the concentration of shots directed to the upper left chest area,
    highlighting the aggravated nature of the crime. When not in
    use during the testimony and closing argument, the mannequin
    was stored outside of the jury’s view and was not placed in the
    jury room during deliberations.
    Steskal asserts there was little probative value to the
    mannequin, given that the circumstances of the crime were not
    contested, and that the mannequin was prejudicial because it
    was “startlingly life-like” and the condition of the uniform was
    “shocking.” This argument is not persuasive; this court has
    repeatedly held that otherwise relevant evidence is not
    38
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    inadmissible simply because it is graphic or because it depicts
    uncontested facts. (People v. Thomas, 
    supra,
     53 Cal.4th at
    p. 806.) In Thomas, for instance, although the cause and
    circumstances of death were not in dispute, we upheld the guilt
    phase introduction of life-sized mannequins representing slain
    officers, as well as their blood- and tissue-stained clothing. (Id.
    at pp. 805–806.) The trial court in this case did not err when it
    admitted similar evidence in Steskal’s penalty retrial, a
    juncture in the proceedings when the constraints on its
    discretion to exclude the evidence were greater than they would
    have been in the guilt phase. (People v. Bell, supra, 7 Cal.5th at
    pp. 105–106.) We have long recognized that “[m]annequins may
    be used as illustrative evidence to assist the jury in
    understanding the testimony of witnesses or to clarify the
    circumstances of a crime” (People v. Cummings (1993) 
    4 Cal.4th 1233
    , 1291) and have “rejected challenges to the prosecution’s
    use of mannequins to represent victims during the presentation
    of aggravating evidence” (People v. Peoples, supra, 62 Cal.4th at
    p. 753). We have similarly upheld the admission of a victim’s
    stained clothing to show the circumstances of the crime (People
    v. Spencer, supra, 5 Cal.5th at p. 680), as well as the admission
    of photographs and videotape portraying actual victims in death
    (see, e.g., People v. Henriquez (2017) 
    4 Cal.5th 1
    , 40
    [photographs]; People v. Cunningham (2015) 
    61 Cal.4th 609
    , 668
    [photographs and videotape]).      “[A]s unpleasant as these
    [depictions] may be, they demonstrate the real-life consequences
    of defendant’s actions. The prosecution was entitled to have the
    penalty    phase     jury   consider    those    consequences.”
    (Cunningham, at p. 668.)
    We also reject Steskal’s claim that the mannequin was
    cumulative of other evidence such as the patrol car and
    39
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    testimony by the pathologist and first responders. When used
    to illustrate the pathologist’s testimony, as the mannequin did
    here, the “demonstrative evidence provides noncumulative
    value over the testimony itself by encapsulating what may
    otherwise be . . . confusing.” (People v. Caro, supra, 7 Cal.5th at
    p. 510.) “[A] prosecutor is not required to rely solely on oral
    testimony when a visual image would enhance the jury’s
    understanding of the issues.” (People v. Cowan, 
    supra,
     50
    Cal.4th at p. 476.)
    We conclude the trial court acted within its discretion in
    finding that the probative value of the mannequin was not
    substantially outweighed by the risk of undue prejudice.
    “Consistent with our holding in People v. Medina (1990) 
    51 Cal.3d 870
    , 898–899 [
    274 Cal.Rptr. 849
    , 
    799 P.2d 1282
    ] — a case
    where the prosecution entered into evidence a mannequin
    wearing a victim’s bloodstained shirt — we find that ‘[t]he trial
    court was in a far better position than we to assess the potential
    prejudice arising from the display of such physical evidence.’
    Upon the record before us, we see no basis to upset its decision”
    (People v. Spencer, supra, 5 Cal.5th at p. 681) and conclude there
    was no violation of Steskal’s federal constitutional rights (People
    v. Henriquez, supra, 4 Cal.5th at p. 29).
    b. Jury view of Deputy Riches’s patrol car
    As in the guilt phase, during the penalty retrial the trial
    court permitted the jury to view Deputy Riches’s patrol car, over
    the defense’s renewed objections. Steskal contends this ruling
    was error, asserting that the patrol car was inflammatory, was
    not relevant to any contested issue, and was cumulative of other
    evidence, including the mannequin, photographs of the patrol
    car, and witness testimony. We find no abuse of discretion.
    40
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Again, evidence may be admissible though undisputed
    (People v. Thomas, 
    supra,
     53 Cal.4th at p. 806; People v. D’Arcy
    (2010) 
    48 Cal.4th 257
    , 299), and it is not unduly prejudicial for
    “ ‘accurately portray[ing] the shocking nature of the crime[]’ ”
    (People v. Zambrano, 
    supra,
     41 Cal.4th at p. 1150).
    Furthermore, in the penalty retrial, the prosecution was entitled
    greater leeway “ ‘to establish the circumstances of the crime,
    including its gruesome consequences,’ ” and “to demonstrate the
    full extent of the suffering defendant inflicted on his victim.”
    (People v. Bell, supra, 7 Cal.5th at p. 106.) “ ‘[T]he penalty phase
    is an especially appropriate time to introduce [evidence]
    showing exactly what the defendant did.’ ” (People v. Johnson
    (2015) 
    61 Cal.4th 734
    , 767–768.)
    We reject Steskal’s assertion that a jury view of the patrol
    car was cumulative of other evidence in the penalty retrial. In
    our review of Steskal’s similar guilt phase claim, we concluded
    that the vehicle was not cumulative of photographs and
    testimony. The same is true for the penalty retrial, where the
    prosecution introduced nearly identical evidence. Although the
    mannequin provided an additional depiction of the crime and
    Deputy Riches’s wounds, the destruction of the patrol car
    uniquely illustrated the firepower Steskal wielded, the number
    and pattern of shots, and the vulnerability of Deputy Riches as
    he sat defenseless in the driver’s seat — circumstances of the
    crime the prosecutor highlighted in closing.
    We therefore conclude that in the penalty retrial, the
    patrol car evidence was “neither cumulative nor misleading and
    [was] highly probative of the penalty issues, demonstrating the
    deliberate and brutal nature of the crime.” (People v. Staten
    (2000) 
    24 Cal.4th 434
    , 463.) The trial court’s decision to admit
    the evidence was not an abuse of discretion or constitutional
    41
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    error.
    c. Admission of autopsy and patrol car
    photographs
    Steskal claims the trial court erred in admitting
    photographs that were unduly prejudicial. At issue were three
    autopsy photographs and 13 photographs of the patrol car and
    other property damaged in the shooting. We find no error.
    The pathologist described 30 major wounds Deputy Riches
    sustained to his head, neck, chest, shoulder, and arms. Three
    autopsy photos admitted into evidence showed severe wounds to
    Deputy Riches’s right hand and forearm. The prosecution later
    emphasized that Deputy Riches’s right hand and weapon were
    struck by gunfire, leaving him defenseless.
    A criminalist testified regarding her collection and
    analysis of bullet casings and other evidence at the scene. She
    explained how she attempted to recreate the position of the
    shooter by examining gunshot damage to the patrol car and
    nearby businesses.        Photographs referenced during the
    criminalist’s testimony and introduced into evidence depicted a
    view of the patrol car from a distance as it was found at the
    scene; bullet holes in the nearby businesses; the shattered
    driver’s window taped in place to preserve bullet hole evidence;
    the interior of the vehicle, including closeup views of damage
    and Deputy Riches’s revolver and radio found on the driver’s
    seat and floor; trajectory rods placed in some of the bullet holes;
    and exterior views of bullet holes in the hood and windshield
    without the trajectory rods.
    Steskal asserts that the photographs lacked probative
    value because they addressed matters that were not in dispute
    and were cumulative of other evidence. We are not persuaded.
    42
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Photographs that depict the crime scene and the victim’s
    wounds are relevant to the penalty determination as evidence of
    the circumstances of the crime (People v. Booker, 
    supra,
     51
    Cal.4th at p. 187) “ ‘ “and the prosecution is ‘not obliged to prove
    these details solely from the testimony of live witnesses,’ ” even
    in the absence of a defense challenge to particular aspects of the
    prosecution’s case’ ” (People v. D’Arcy, 
    supra,
     48 Cal.4th at
    p. 299). As we have explained, “[p]hotographs and other graphic
    evidence are not rendered ‘irrelevant or inadmissible simply
    because they duplicate testimony[ or] depict uncontested
    facts . . . .’ ” (People v. Thomas, 
    supra,
     53 Cal.4th at p. 806.)
    Furthermore, most of the photographs illustrated circumstances
    of the crime that were not conveyed by the mannequin and an
    external view of the patrol car: incapacitating injury to Deputy
    Riches’s hand, damage to nearby businesses, the position of the
    patrol car at the scene, items as they were found in the driver’s
    seat area, and closeup details of damage viewed from the
    interior of the vehicle.
    Steskal points to empirical studies regarding the dramatic
    effect gruesome photographs may have on jury decisionmaking
    and contends the photographs admitted in his trial were likely
    to have had an improper impact on the penalty verdict.
    “Defendant did not raise that objection at trial, and the studies
    in question are not part of the trial record. Thus, the trial court
    was not provided an opportunity to consider the relevance of the
    studies in weighing the potential for undue prejudice against
    the probative value of the photographs.” (People v. Sattiewhite
    (2014) 
    59 Cal.4th 446
    , 472.)
    We have viewed the photographs and conclude the trial
    court did not abuse its discretion in admitting them. “ ‘ “A trial
    court’s decision to admit photographs under Evidence Code
    43
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    section 352 will be upheld on appeal unless the prejudicial effect
    of such photographs clearly outweighs their probative value.” ’ ”
    (People v. Henriquez, supra, 4 Cal.5th at p. 40.) The autopsy
    photographs were “tightly cropped” to show only Deputy
    Riches’s hand and arm and photographs of the patrol car were
    “neither gory nor particularly disturbing.” (People v. Jackson
    (2014) 
    58 Cal.4th 724
    , 757.) The evidence was “ ‘neither unduly
    gruesome nor inflammatory’ ” (ibid.), would not have interfered
    with the jury’s rational decisionmaking, and did not represent
    an abuse of discretion or a violation of Steskal’s constitutional
    rights.
    4. Admission of victim impact testimony
    Steskal claims that victim impact testimony rendered his
    penalty retrial fundamentally unfair because it was more
    extensive and emotional than the federal Constitution allows.
    We reject this claim.
    a. Background
    As previously indicated, Deputy Riches’s parents, best
    friend, and three coworkers testified for part of an afternoon.
    Their testimony spans 45 pages of transcript.
    Deputy Riches’s father, Bruce Riches, testified only briefly
    to describe his depression following the murder and visits to his
    son’s gravesite. He identified a photograph of Deputy Riches
    taken a few years before his death.
    Deputy Riches’s mother, Meriel Riches, testified about
    brain trauma at birth that caused Deputy Riches to have a
    learning disability and problems with coordination.    He
    succeeded in school through “sheer determination.” He also
    loved participating in the marching band, although he almost
    quit out of concern his disability would hold the group back.
    44
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Even as a teenager, Deputy Riches helped others — building a
    chicken coop for one elderly couple and a mountainside stairway
    for another. She testified that he was “brimming over with love
    and generosity.”
    James Henery, a captain with the Santa Ana Fire
    Department, testified that Deputy Riches had been his best
    friend since high school. Recalling times when they were
    volunteer firefighters together, Henery described arriving at the
    scene of a man’s death and Deputy Riches’s compassion in
    comforting the man’s wife. When they worked together at a
    home for the disabled, Deputy Riches learned sign language so
    that he could speak to a resident who was deaf. Deputy Riches
    was close to Henery’s children and wanted a family of his own.
    He was a loyal friend who would listen to Henery’s problems
    without judgment and someone who was always willing to help
    others. Henery identified photographs of Deputy Riches as a
    teenager, of a trip they took together two years before his death,
    and of Deputy Riches in uniform when he was staffing a booth
    at the county fair.
    Scott Vanover, an OCSD deputy, testified about the strong
    friendship he developed with Deputy Riches even though they
    worked together for less than a year. Vanover’s brother died
    during their childhood and the impact of Deputy Riches’s death
    was similar to the experience of losing his brother. Vanover
    described a trip to London with Deputy Riches, and Deputy
    Riches’s willingness to talk to strangers — Riches was positive
    almost to the point of being naïve. Vanover identified a
    photograph of Deputy Riches on their London trip.
    Eric Hendry was an OCSD deputy and Deputy Riches’s
    training officer. He described the bond of training officer to
    45
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    trainee — “almost like brothers” — and the profound effect of
    Deputy Riches’s murder on his marriage, relationship with his
    children, attitude about his job, and connection to God.
    Joseph Hoskins met Deputy Riches when they were both
    new OCSD deputies working in the jail. He described providing
    aid to an inmate who was having a seizure and Deputy Riches’s
    encouragement and support through the experience.         He
    testified that Deputy Riches was a “comforting force” and
    someone on whom he could rely.
    b. Discussion
    Steskal argues that “highly emotional” testimony from
    these six witnesses violated his constitutional rights.
    “Unless it invites a purely irrational response, evidence of
    the effect of a capital murder on the loved ones of the victim and
    the community is relevant and admissible under [Penal Code]
    section 190.3, factor (a) as a circumstance of the crime.
    [Citation.] The federal Constitution bars victim impact evidence
    only if it is so unduly prejudicial as to render the trial
    fundamentally unfair.” (People v. Brady (2010) 
    50 Cal.4th 547
    ,
    574.) We have repeatedly held that “ ‘[a]dmission of testimony
    presented by a few close friends or relatives of each victim, as
    well as images of the victim while he or she was alive,’ ” is
    constitutionally permissible. (People v. Murtishaw (2011) 
    51 Cal.4th 574
    , 595.)
    In Brady, for example, where the victim was also a law
    enforcement officer, we upheld testimony by a physician, three
    law enforcement officers, and five family members who
    discussed the victim’s “childhood hardships, his lifelong desire
    to be a police officer, his achievements, his engagement and
    future plans, his death, his funeral service, and the aftereffects
    46
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    of his death.” (People v. Brady, 
    supra,
     50 Cal.4th at p. 573; see
    also People v. Spencer, supra, 5 Cal.5th at p. 678 [seven
    witnesses for one victim]; People v. Simon, supra, 1 Cal.5th at
    p. 140 [six witnesses and 59 pages of testimony].) We decline
    Steskal’s invitation to overrule this precedent, which dictates
    our conclusion that the nature and amount of victim impact
    evidence in Steskal’s penalty retrial was constitutionally
    acceptable.
    Steskal does not point to specific testimony or evidence
    when he claims that witnesses conveyed information in a
    “highly emotional manner” that was particularly inflammatory
    when considered in the context of other evidence, such as the
    mannequin and patrol car. “The question is not simply whether
    victim impact evidence was emotional or demonstrated the
    devastating effect of the crime; rather, it is whether the
    testimony invited an irrational response from the jury.” (People
    v. Simon, supra, 1 Cal.5th at p. 140.) Here, Steskal “provides no
    persuasive basis for us to conclude that the testimony presented
    in this case triggered such a response. And our review of the
    record indicates the testimony was not so emotional that the
    trial court’s failure to exclude it amounted to an abuse of
    discretion or rendered [defendant’s] trial fundamentally unfair.”
    (Ibid.)
    Finally, Steskal argues that testimony by nonfamily
    members should have been excluded. This is an argument we
    have previously rejected. “Neither the United States Supreme
    Court nor this court has ever identified a constitutional or
    statutory basis for so constraining the permissible scope of
    victim impact testimony (see Payne v. Tennessee [(1991)] 501
    U.S. [808,] 822–823 [prosecution may be permitted to show the
    loss to the community as a whole]; id. at p. 830 (conc. opn. of
    47
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    O’Connor, J.) [same]; People v. Pearson, supra, 56 Cal.4th at
    pp. 466–467; People v. Thomas (2011) 
    51 Cal.4th 449
    , 507–508
    [
    121 Cal.Rptr.3d 521
    , 
    247 P.3d 886
    ]; People v. Ervine (2009) 
    47 Cal.4th 745
    , 792–793 [
    102 Cal.Rptr.3d 786
    , 
    220 P.3d 820
    ]), and
    because [defendant] offers no persuasive reasons that would
    render these authorities inapposite, we again decline to do so
    here.” (People v. Trinh (2014) 
    59 Cal.4th 216
    , 246.)
    5. Admission of evidence and instruction on the
    attempted jail escape
    Steskal claims the trial court erred when it admitted
    evidence of his attempted escape from jail and instructed the
    jury to consider this incident as aggravating. We conclude no
    error occurred.
    a. Background
    While Steskal was in jail awaiting the penalty retrial,
    correctional staff discovered a small portion of his cell wall
    scraped away, found strips of bed sheet hidden in his mattress,
    and confiscated portions of metal blades and clippers in his
    possession, some fashioned into hand-held instruments. The
    defense conceded that the question of whether the metal
    instruments were weapons or scraping tools was one for the jury
    but argued there was insufficient evidence of a threat of force or
    violence to support admission of the escape attempt. The trial
    court found evidence of multiple crimes admissible pursuant to
    Penal Code section 190.3, factor (b): attempted escape (Pen.
    Code, §§ 4532, subd. (b), 664); possession of sharp instruments
    (id., § 4502); and possession of at least two deadly weapons (id.,
    § 4574).
    During the penalty retrial, the prosecution presented
    evidence that Steskal possessed contraband metal items in jail:
    48
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    a hair clipper blade attached to a paper handle; portions of nail
    clippers; and a “shank,” a handheld weapon made with metal
    from a large toenail clipper. A correctional expert testified that
    the shank and hair clipper blade could be used to stab and slash
    and were potentially dangerous weapons.
    The prosecution also presented evidence that Steskal had
    been chipping at the wall between his cell and an adjoining
    mechanical room that contained a ventilator shaft. He had
    managed to scrape away a patch in the 24-inch-thick concrete
    wall that was a third of an inch deep. While the mechanical
    room was locked from the outside, there was no barrier to
    exiting it once inside; a person could also move through the
    ventilation system to the roof of the jail, though access to the
    roof was blocked by metal bars. The strips of bed sheets Steskal
    saved were long enough to enable his descent from the roof of
    the jail to the street. Because the jail was in a building that also
    housed the city police department, correctional and other law
    enforcement personnel were often present on the street on their
    way to and from work.
    b. Discussion
    “Evidence of actual or threatened violent criminal activity
    ‘that would allow a rational trier of fact to find the existence of
    such activity beyond a reasonable doubt’ is admissible under
    [Penal Code section 190.3,] factor (b). [Citation.] Such evidence
    must involve actual, attempted, or threatened force or violence
    against a person, and not merely to property.” (People v. Wallace
    (2008) 
    44 Cal.4th 1032
    , 1079.)          Factor (b) encompasses
    “attempted use of force or violence or the express or implied
    threat to use force or violence.” (Pen. Code, § 190.3, factor (b).)
    “A trial court’s decision to admit, at the penalty phase, evidence
    49
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    of a defendant’s prior criminal activity is reviewed under the
    abuse of discretion standard.” (People v. Bacon (2010) 
    50 Cal.4th 1082
    , 1127.)
    When considering evidence of escape in the context of
    Penal Code section 190.3, factor (b), “we must review the factual
    setting of each particular escape to determine whether it
    involved actual or threatened violence and not presume that the
    escape was violent because of the possibility of violence in
    reapprehension.” (People v. Jackson (1996) 
    13 Cal.4th 1164
    ,
    1257, fn. 2; see People v. Boyd (1985) 
    38 Cal.3d 762
    , 776–777.)
    Thus, “[a]lthough evidence of attempted escape alone is not
    admissible under section 190.3, factor (b),” we have found escape
    evidence sufficient in a variety of circumstances indicating a
    threat of violence: when the defendant possessed a weapon and
    had a plan to use it (People v. Romero and Self (2015) 
    62 Cal.4th 1
    , 49); when the defendant attempted to obtain a shank as “ ‘a
    ticket out’ ” and possessed torn mattress covers (People v.
    Gallego (1990) 
    52 Cal.3d 115
    , 155; see id. at p. 196); when the
    defendant planned to use a weapon if necessary but had not yet
    obtained one (People v. Boyde (1988) 
    46 Cal.3d 212
    , 250); and
    when the defendant did not possess a weapon, but the escape
    plan would have required him to confront a guard (People v.
    Mason (1991) 
    52 Cal.3d 909
    , 955–956). In contrast, we have
    concluded that evidence of escape was not admissible when
    there was “no evidence that violence was being planned or even
    prepared for.” (Jackson, at p. 1256.)
    Steskal argues on appeal, as he did at trial, that there was
    insufficient evidence his attempted escape involved a threat of
    force or violence. He claims the contraband metal clippers were
    for digging out of his cell and no evidence established his intent
    to use them as weapons. Our cases establish, however, that
    50
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    “possession of a potentially dangerous weapon in custody ‘is
    unlawful and involves an implied threat of violence even where
    there is no evidence defendant used or displayed it in a
    provocative or threatening manner.’ ” (People v. Delgado (2017)
    
    2 Cal.5th 544
    , 586.) “ ‘The trier of fact is free to consider any
    “innocent explanation” for defendant’s possession of the item,
    but such inferences do not render the evidence inadmissible per
    se.’ ” (People v. Jurado (2006) 
    38 Cal.4th 72
    , 139–140.)
    The jury could infer from evidence presented that Steskal
    planned to escape by scraping a hole in his cell wall and exiting
    the jail with the aid of a rope made of bedsheets. Testimony that
    a shank and other metal items in his possession could be used
    as dangerous weapons supported an implied threat of violence.
    The trial court’s decision that this was sufficient evidence of
    attempted escape for admission pursuant to Penal Code section
    190.3, factor (b) was not an abuse of discretion. (People v.
    Gallego, supra, 52 Cal.3d at p. 196.)
    Even if evidence of the attempted escape fell short of that
    sufficient to establish threatened violent criminal activity
    beyond a reasonable doubt, its admission was harmless. Steskal
    does not challenge the trial court’s conclusion that his
    possession of multiple sharp instruments (Pen. Code, § 4502)
    and deadly weapons (id., § 4574) was admissible under Penal
    Code section 190.3, factor (b). (People v. Landry (2016) 
    2 Cal.5th 52
    , 118; People v. Wallace, 
    supra,
     44 Cal.4th at p. 1082.)
    Addressing the issue in closing argument, the prosecution
    highlighted Steskal’s manufacture of weapons and argued that
    he would pose a danger to correctional staff in any setting; this
    argument did not depend on the conclusion that Steskal
    specifically intended to use the weapons to commit violence in
    an escape. And Steskal himself relied on evidence of the escape
    51
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    to counter the suggestion he was dangerous, arguing that he did
    not intend to use the contraband clippers and blades as weapons
    but as tools to scrape the wall. Under these circumstances, we
    conclude that excluding evidence of Steskal’s escape efforts —
    scraping away a small patch of cell wall and concealing strips of
    bedsheets — would not have affected the jury’s verdict.
    Steskal contends the trial court’s error in admitting Penal
    Code section 190.3, factor (b) evidence was exacerbated by
    instructing the jury to consider it. Finding no error in the
    admission of the evidence, we reject this claim.
    6. Instructional error regarding unadjudicated
    offenses
    Steskal contends that a pattern instruction regarding
    Penal Code section 190.3, factor (b) evidence, CALJIC No. 8.87,
    improperly removed from the jury the task of determining
    whether alleged criminal activities involved an actual or implied
    threat of violence. He asserts the instruction also improperly
    defined the requisite criminal acts as requiring the “implied use”
    rather than “implied threat” of force or violence, and explains
    that a threat involves an intention to use force or violence but
    does not necessarily lead to violence. As we have observed,
    “these claims are common objections, previously rejected.”
    (People v. Bryant, Smith and Wheeler (2014) 
    60 Cal.4th 335
    ,
    451.)
    First, the question whether there was an actual or implied
    threat of violence was not for the jury to decide. “Although the
    question of whether the acts occurred is a factual matter for the
    jury, the characterization of those acts as involving an express
    or implied use of force or violence, or the threat thereof, is a legal
    matter for the court to decide.” (People v. Manibusan (2013) 58
    52
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Cal.4th 40, 96.)
    Steskal’s second assertion regarding improperly defined
    terms is “neither the only nor most reasonable understanding of
    the instruction.” (People v. Bryant, Smith and Wheeler, supra,
    60 Cal.4th at p. 452.) “[E]ven if the instruction did not clearly
    define the types of possible threats, it did not explicitly tell the
    jury that a threat to use force or violence necessarily was an
    actual threat, rather than an implied one. Defendant[] w[as] not
    precluded from arguing that [his] offenses involved only implied
    threats and that the jury should give less aggravating weight to
    that evidence.” (Ibid.)
    7. Constitutionality of the death penalty for mentally
    ill defendants
    Steskal claims the Eighth Amendment to the United
    States Constitution categorically prohibits the death penalty for
    individuals with severe mental illness. He further contends
    that, given his delusional disorder, a death sentence is
    constitutionally disproportionate to his personal culpability. We
    have rejected similar claims on several occasions. (E.g., People
    v. Ghobrial, supra, 5 Cal.5th at pp. 275–276; People v. Mendoza
    (2016) 
    62 Cal.4th 856
    , 908–909.) Consistent with our precedent,
    we reject Steskal’s claim as well.
    The Eighth Amendment prohibition against cruel and
    unusual punishments is interpreted by referring to “ ‘evolving
    standards of decency . . .’ to determine which punishments are
    so disproportionate as to be cruel and unusual.” (Roper v.
    Simmons (2005) 
    543 U.S. 551
    , 561 (Roper).) This inquiry begins
    with “a review of objective indicia of consensus, as expressed in
    particular by the enactments of legislatures that have addressed
    the question.” (Id. at p. 564; see Atkins v. Virginia (2002) 536
    53
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    U.S. 304, 312 (Atkins).) We have observed that “while Atkins
    and Roper had relied on the emergence of a national consensus
    against the imposition of the death penalty in cases of
    intellectual disability2 and in cases involving juvenile offenders,
    there exists no similar evidence that a national consensus has
    formed against the imposition of the death penalty against the
    class of persons with mental illness.” (People v. Ghobrial, supra,
    5 Cal.5th at p. 275; see also People v. Mendoza, supra, 62 Cal.4th
    at p. 909; People v. Boyce (2014) 
    59 Cal.4th 672
    , 722.)
    Steskal asks us to reexamine this conclusion, contending
    that a national consensus is evident in a type of insanity defense
    — “volitional incapacity” — available in seven states that
    impose the death penalty and in decisions from states that have
    prohibited capital punishment for particular mentally ill
    offenders through individual proportionality review.           The
    insanity defense Steskal cites, however, is a traditional defense
    to criminal liability that “surfaced over two centuries ago”
    (Clark v. Arizona (2006) 
    548 U.S. 735
    , 749) and is unrelated to
    sentencing. Furthermore, the most recent of the state laws
    reflecting the defense have been in place for decades. Similarly,
    of the handful of individual proportionality cases Steskal cites,
    only one was decided in this century. Neither these historical
    decisions nor the existence of an age-old insanity defense
    reflects a “trend toward abolition” of the death penalty for
    persons with mental illness. (Roper, supra, 543 U.S. at p. 566.)
    Steskal and his amici curiae claim that additional sources
    reflect community and international consensus in support of his
    2
    We use the term “intellectual disability” in accordance
    with current terminology except when quoting from other
    sources. (People v. Woodruff (2018) 
    5 Cal.5th 697
    , 737, fn. 5.)
    54
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    claim, including opinion polls, positions taken by mental health
    organizations and the American Bar Association (ABA), and
    United Nations resolutions.       (See, e.g., ABA Section on
    Individual Rights and Responsibilities, Report of the Task Force
    on Mental Disability and the Death Penalty (2005) (ABA Task
    Force Report)  [as of Apr. 29, 2021].) (All
    Internet citations in this opinion are archived by year, docket
    number,            and           case          name           at
    .) These materials are,
    however, identical or substantially similar to materials we have
    already held “insufficient to demonstrate emerging standards
    that warrant reexamination of our precedent.” (People v.
    Ghobrial, supra, 5 Cal.5th at p. 276, citing People v. Mendoza,
    supra, 62 Cal.4th at p. 910.)
    As evidence of a national consensus, Steskal also
    highlights legislation recently enacted in Ohio that allows
    defendants to establish ineligibility for the death penalty if they
    have been diagnosed with one of four serious mental illnesses,
    including delusional disorder. But while our Legislature may
    consider following Ohio’s lead in approaching this issue (People
    v. Hajek and Vo (2014) 
    58 Cal.4th 1144
    , 1252; People v.
    Mendoza, supra, 62 Cal.4th at p. 909), the recent Ohio
    legislation is not, at this point, sufficient to establish a national
    consensus for purposes of the Eighth Amendment analysis.
    (Compare Atkins, supra, 536 U.S. at p. 314.)
    In rejecting claims similar to Steskal’s, our cases have
    emphasized the inherent difficulty of defining mental illness for
    categorical Eighth Amendment exemption and explained that
    the Legislature is in the best position to address the issue if it
    so chooses: “ ‘There are a number of different conditions
    55
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    recognized as mental illnesses, and the degree and manner of
    impairment in a particular individual is often the subject of
    expert dispute. Thus, while it may be that mentally ill offenders
    who are utterly unable to control their behavior lack the
    extreme culpability associated with capital punishment, there is
    likely little consensus on which individuals fall within that
    category or precisely where the line of impairment should be
    drawn. . . . We leave it to the Legislature, if it chooses, to
    determine exactly the type and level of mental impairment that
    must be shown to warrant a categorical exemption from the
    death penalty.’ ” (People v. Mendoza, supra, 62 Cal.4th at
    p. 909.)
    Steskal acknowledges this definitional difficulty but
    argues it does not defeat his claim.             Referencing
    recommendations from the ABA Task Force Report, Steskal
    proposes a definition of severe mental illness that includes
    schizophrenia and other psychotic disorders, which, in their
    acute state, are associated with significant disruptions in
    thinking and perception. Because the effects of such conditions
    may not be constant, however — for example, persons with a
    delusional disorder may not experience such disruptions all or
    most of the time — Steskal adds the consideration of case-
    specific factors to his definition of severe mental illness,
    explaining that it is intended to signify a “class of offenders who
    are not just severely mentally ill, but whose severe mental
    illness was causally related to the offense itself.”
    By these descriptions it is apparent that Steskal’s is not a
    categorical approach to defining a class of offenders with mental
    illness; instead, it raises the question whether “the penalty was
    unwarranted under the facts of [a] particular case,” an inquiry
    into individual culpability that must be conducted on a case-by-
    56
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    case basis. (People v. Mendoza, supra, 62 Cal.4th at p. 911.) The
    ABA Task Force Report on which Steskal relies confirms the
    point, explaining that although Atkins “dispensed with a case-
    by-case assessment of responsibility” for a class defined by
    intellectual disability, in matters involving severely mentally ill
    offenders “preclusion of a death sentence based on diagnosis
    alone would not be sensible, because the symptoms of these
    disorders are much more variable than those associated with
    retardation . . . .” (ABA Task Force Rep., supra, at p. 4; see also
    Slobogin, What Atkins Could Mean for People with Mental
    Illness (2003) 33 N.M. L.Rev. 293, 309 [defendants should
    demonstrate their symptoms during the relevant time period to
    account for variability associated with mental illness].) These
    observations are consistent with our prior conclusion that there
    is “ ‘likely little consensus’ ” on “ ‘where the line of impairment
    should be drawn’ ” as a categorical matter or “ ‘which
    individuals fall within that category.’ ” (Mendoza, at p. 909.)
    Steskal argues that offenders with severe mental illness
    are in pertinent respects similarly situated to intellectually
    disabled and juvenile offenders, and therefore should also be
    categorically exempt from capital punishment. He notes that in
    reaching its holding in Atkins, the high court explained that
    recognized justifications for the death penalty — retribution and
    deterrence — did not apply to intellectually disabled offenders,
    whose impairments render them both less morally culpable and
    “make it less likely that they can . . . control their conduct based
    upon” a threat of execution. (Atkins, supra, 536 U.S. at p. 320.)
    In Roper, the high court reached similar conclusions with
    respect to offenders under the age of 18. (Roper, 
    supra,
     543 U.S.
    at p. 571.) Steskal argues that capital punishment similarly
    fails to serve as a deterrent or proper retribution for those with
    57
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    severe mental illness. He also argues that, as with intellectually
    disabled and juvenile offenders, individuals with severe mental
    illness may have impairments that hinder their relationship
    with counsel, limit their ability to competently navigate other
    aspects of the criminal justice system, and enhance the
    likelihood a jury would attribute future dangerousness to them.
    (See Atkins, at p. 320.) Again, precedent forecloses Steskal’s
    arguments. We have previously explained that the application
    of the death penalty to individuals with mental illness presents
    different considerations than its application to intellectually
    disabled and juvenile offenders. As Steskal and amici curiae
    acknowledge, mental illness affects different individuals
    differently, may wax and wane in severity over time, and even
    those with severe mental illness may have periods of functioning
    adequately. Although some mentally ill offenders may “lack the
    extreme culpability associated with capital punishment” (People
    v. Mendoza, supra, 62 Cal.4th at p. 909), Steskal has not
    demonstrated that such impairment “is so widespread among all
    types of serious mental illnesses that all those so diagnosed
    must be spared the death penalty” (id. at p. 911) because the
    penalty “would not serve societal goals of retribution and
    deterrence” (id. at p. 909).
    As for Steskal’s argument regarding reduced capacity to
    assist counsel, “to the extent that Atkins and Roper were
    concerned with the risk of ‘unjustified or mistaken execution’ in
    the case of persons with intellectual disabilities and juvenile
    offenders, significant variations in the forms and nature of
    mental illness make it difficult to say that impaired competence
    is a feature common to the class.” (People v. Ghobrial, supra, 5
    Cal.5th at p. 275.) That is to say, we are unable to attribute to
    all severely mentally ill defendants a degree of impairment that
    58
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    necessarily threatens the exercise of rights or undermines the
    ability to present a compelling case in mitigation, though of
    course “[a]ll defendants, including this one, have the
    opportunity to establish that they are not competent to stand
    trial.” (People v. Mendoza, supra, 62 Cal.4th at p. 911.) Nor
    does the risk that mental illness may be wrongfully associated
    with future dangerousness in some cases establish a categorical
    basis for excluding all those who experience such a condition
    from capital punishment — though we emphasize that in every
    case a defendant is entitled to the benefit of established limits
    on arguments and evidence concerning future dangerousness.
    (See People v. Banks (2014) 
    59 Cal.4th 1113
    , 1185–1186.)
    These acknowledged differences between the groups of
    offenders answer Steskal’s argument that it violates equal
    protection to treat individuals with mental illness differently
    from intellectually disabled and juvenile offenders: Given the
    variation among offenders affected by mental illness, we have
    held that the class of persons with mental illness are not
    similarly situated to those who are minors or intellectually
    disabled for purposes of equal protection. (People v. Mendoza,
    supra, 62 Cal.4th at p. 912; People v. Boyce, supra, 59 Cal.4th at
    p. 723.) These conclusions do not prevent an individual from
    arguing that “the penalty was unwarranted under the facts of
    [a] particular case . . . .” (Mendoza, at p. 911.) But they do
    foreclose the categorical approach Steskal urges us to adopt.
    In the alternative, Steskal requests intracase
    proportionality review, contending that his death sentence is
    disproportionate to his individual culpability. The Eighth
    Amendment to the federal Constitution prohibits the imposition
    of a penalty that is disproportionate to the defendant’s “personal
    responsibility and moral guilt.” (Enmund v. Florida (1982) 458
    59
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    U.S. 782, 801.) California’s Constitution establishes the same
    prohibition. (Cal. Const., art. I, § 17.) Thus, to determine
    whether a sentence is cruel or unusual, we examine the
    circumstances of the offense and consider the defendant’s
    personal characteristics, including age, prior criminality, and
    mental capabilities. (People v. Mendoza, supra, 62 Cal.4th at
    p. 911; see also People v. Landry, supra, 2 Cal.5th at p. 125
    [intracase proportionality review conducted upon request].) A
    sentence is unconstitutional when the penalty is “grossly
    disproportionate to the offense” (People v. Dillon (1983) 
    34 Cal.3d 441
    , 450) so that it “ ‘shocks the conscience and offends
    fundamental notions of human dignity’ ” (People v. Frierson
    (1979) 
    25 Cal.3d 142
    , 183; see Mendoza, at pp. 911–912).
    Evidence at trial indicated that Steskal was extremely
    agitated after leaving his remote camp and returning to town
    for legal matters related to a prior traffic stop. Shortly before
    the crime, he could be heard loudly slamming objects and
    repeatedly yelling that he hated the world. When he went to a
    7-Eleven for cigarettes, Steskal carried a semiautomatic rifle he
    claimed was for protection against the “fucking law.” As Deputy
    Riches arrived at the store, Steskal fired 30 rounds directly at
    him from close range, with no provocation, and before Deputy
    Riches could exit his patrol car or draw his gun. The prosecution
    presented additional evidence that Steskal threatened a police
    officer many years earlier by racing toward him on a motorcycle.
    Before his penalty retrial, correctional staff found Steskal
    preparing for an escape and accumulating contraband metal
    blades and clippers to chip away at his wall and/or use as
    weapons.
    In his defense, Steskal presented considerable lay and
    expert testimony regarding his difficult childhood and long-
    60
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    standing mental health problems. As an adult, he was isolated,
    tormented by irrational and severe paranoia, and frequently
    suicidal. There was evidence that following a traffic stop in
    which he was mistreated by sheriff’s deputies, Steskal’s mental
    health deteriorated significantly — at the time of the crime, he
    held the delusional belief that law enforcement officers wanted
    to kill him. Despite this evidence, the jury rejected defense
    arguments for lesser culpability. The jury reached its penalty
    verdict after considering evidence of Steskal’s childhood abuse
    and family dysfunction, chronic mental illness, persistent
    developmental problems, lack of a criminal record, and kindness
    toward others.
    Much as in prior cases, we cannot say that evidence of
    Steskal’s mental illness or other characteristics renders his
    capital sentence grossly disproportionate to his crime. (See
    People v. Mendoza, supra, 62 Cal.4th at p. 911; People v. Boyce,
    supra, 59 Cal.4th at p. 721 [citing cases]; People v. Lawley (2002)
    
    27 Cal.4th 102
    , 171.) Having given careful consideration to this
    evidence, the jury determined both that Steskal’s murder of
    Deputy Riches was premeditated and deliberate and that death
    was the appropriate penalty. Given the circumstances of the
    murder and “in light of the careful consideration already
    accorded to defendant’s evidence of mental illness at the trial
    level” (Mendoza, at p. 912), we cannot say the penalty is
    unconstitutionally disproportionate.
    8. Constitutionality of the death penalty statute
    Steskal presents a number of challenges to California’s
    death sentencing scheme, acknowledging that we have
    previously rejected them. We decline to revisit our precedent
    and hold as follows:
    61
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    There is no merit to Steskal’s claim that the special
    circumstances set forth in Penal Code section 190.2 fail to
    perform their constitutionally required narrowing function, or
    that Penal Code section 190.3, factor (a), which allows the jury
    to consider the “circumstances of the crime” when making a
    penalty determination, results in the arbitrary and capricious
    imposition of the death penalty. (People v. Ghobrial, supra, 5
    Cal.5th at p. 291; People v. Linton (2013) 
    56 Cal.4th 1146
    , 1214–
    1215.)
    We also reject Steskal’s claims that additional procedural
    safeguards are required to ensure constitutionally reliable
    sentencing. “[T]his court has repeatedly rejected arguments
    that the federal Constitution requires the penalty phase jury to
    make unanimous written findings beyond a reasonable doubt
    that the aggravating factors exist, that they outweigh the
    factors in mitigation, and that death is the appropriate penalty.”
    (People v. Brooks (2017) 
    3 Cal.5th 1
    , 115; see People v. Johnson
    (2016) 
    62 Cal.4th 600
    , 655–656.) “The United States Supreme
    Court’s decisions interpreting the Sixth Amendment’s jury trial
    guarantee [citations] do not call into question these
    conclusions.” (Johnson, at p. 655.) There is likewise no violation
    of due process or Sixth Amendment jury trial rights in allowing
    the jury to consider prior unadjudicated crimes aggravating
    under Penal Code section 190.3, factor (b), and to do so without
    unanimously finding Steskal guilty of those crimes. (Johnson,
    at p. 656.) Finally, “there is no Eighth Amendment requirement
    that California’s death penalty scheme provide for intercase
    proportionality review” (Johnson, at p. 656) and “the failure to
    afford capital defendants at the penalty phase some of the
    procedural safeguards guaranteed to noncapital defendants . . .
    does not violate the equal protection clause” (id. at p. 657).
    62
    PEOPLE v. STESKAL
    Opinion of the Court by Kruger, J.
    Contrary to Steskal’s claim, “ ‘the statutory instruction to
    the jury to consider “whether or not” certain mitigating factors
    were present [does] not unconstitutionally suggest that the
    absence of such factors amounted to aggravation.’ ” (People v.
    Jones (2012) 
    54 Cal.4th 1
    , 87.)
    Steskal contends evolving standards of decency have
    rendered the death penalty unconstitutional. He claims the
    increasing number of states that have abolished the death
    penalty and its declining use in states that retain it reflect a
    national consensus against capital punishment. Steskal asserts
    that additional factors — the rising number of exonerations,
    race and gender disparities, and delay — further justify a
    conclusion that the death penalty is unreliable, arbitrary, and
    cruel and unusual in violation of Eighth Amendment
    protections.
    We are not prepared to say that the trends Steskal cites
    reflect rejection of the death penalty “in the majority of States”
    (Roper, supra, 543 U.S. at p. 567), or that the record before us
    establishes arbitrariness violative of the Eighth Amendment
    (see People v. Seumanu, supra, 61 Cal.4th at p. 1374). We thus
    decline to revisit the conclusion we have repeatedly reached,
    that “California’s use of the death penalty does not violate
    international law, the federal Constitution, or the Eighth
    Amendment’s prohibition against cruel and unusual
    punishment in light of ‘evolving standards of decency.’ ” (People
    v. Mitchell (2019) 
    7 Cal.5th 561
    , 590.)
