    SUMMARY*
    Habeas Corpus / Death Penalty
    The panel affirmed the district court’s denial of Clarence
    Wayne Dixon’s habeas corpus petition challenging his
    Arizona state murder conviction and death penalty.
    The panel applied deferential review under the
    Antiterrorism and Effective Death Penalty Act of 1996.
    The panel held that the district court properly held that
    Dixon’s Sixth Amendment right to effective assistance of
    counsel was not violated when his trial counsel elected not to
    challenge Dixon’s competency to waive counsel, despite
    counsel’s knowledge that Dixon had a history of mental
    health issues. The panel held that the Arizona Superior
    Court’s denial of Dixon’s petition for post-conviction relief
    did not unreasonably apply Strickland v. Washington, 
    466 U.S. 668
    (1984), and that the record demonstrates that the
    Arizona Superior Court did not rely on an unreasonable
    determination of the facts.
    The panel held that the district court properly concluded
    that Dixon’s due process rights were not violated by the state
    trial court’s failure to hold a competency hearing sua sponte.
    The panel held that the state post-conviction-relief court’s
    determination without a hearing that Dixon was competent to
    waive counsel and represent himself was not an unreasonable

    determination of the facts, nor was it contrary to clearly
    established law.
    The panel held that the district court properly held that the
    Arizona Supreme Court’s opinion concluding that the trial
    court did not abuse its discretion in denying Dixon’s final
    request for a continuance was neither contrary to, nor an
    unreasonable application of, clearly established law; and did
    not rest on an unreasonable determination of the facts.
    The panel expanded the certificate of appealability to
    cover Dixon’s claim that his Sixth and Fourteenth
    Amendment rights were violated when he was shackled and
    subject to electronic restraints during the trial. As to that
    claim, the panel held that the Arizona Supreme Court’s
    determination that Dixon was not prejudiced because the jury
    did not see the restraints was neither an unreasonable
    determination of the facts nor an application of Deck v.
    Missouri, 
    544 U.S. 622
    (2005), contrary to clearly established
    federal law. The panel held that in holding in the alternative
    that any error under Deck was harmless, the Arizona Supreme
    Court did not apply Chapman v. California, 
    386 U.S. 18
    (1967), in an objectively unreasonable manner. The panel
    held that the Arizona Supreme Court’s factual conclusions
    regarding the visibility of the restraints were not
    unreasonable.
    The panel declined to expand the COA as to other issues.

    OPINION
    THOMAS, Chief Judge:
    An Arizona jury convicted Clarence Wayne Dixon of the
    1977 murder of Deana Bowdoin and imposed the death
    penalty. Dixon appeals the district court’s denial of his
    petition for a writ of habeas corpus pursuant to 28 U.S.C.
    § 2254. We have jurisdiction pursuant to 28 U.S.C. §§ 1291
    and 2253. We review a district court’s denial of a habeas
    corpus petition de novo, Hall v. Haws, 
    861 F.3d 977
    , 988
    (9th Cir. 2017), and we affirm. We expand the certificate of
    appealability (“COA”) as to Dixon’s claim that his rights
    were violated under the Sixth and Fourteenth Amendments
    when he was shackled and subject to electronic restraints
    during the trial. We affirm the district court’s denial of the
    petition on that issue.

    The factual and procedural history of this case spans over
    four decades and has been discussed at length by Arizona
    state courts and federal courts. A summary of the history
    relevant to resolution of the claims before us follows.
    A
    In June 1977, Dixon struck a teenage girl with a metal
    pipe. Dixon v. Ryan (Dixon II), No. CV-14-258-PHX-DJH,
    
    2016 WL 1045355
    , at *4 (D. Ariz. Mar. 16, 2016) (order)
    (unpublished decision). Dixon was charged with assault with
    a deadly weapon in Maricopa County Superior Court. 
    Id. at *4.
    The trial court appointed two psychiatrists, Drs.
    Bendheim and Tuchler, to evaluate Dixon, as then required
    by Rule 11 of the Arizona Rules of Criminal Procedure. 
    Id. Both doctors
    determined that Dixon was not competent to
    stand trial, noting his depression and difficulty
    communicating. Both doctors opined that Dixon suffered
    from “undifferentiated schizophrenia.” Dr. Benheim opined
    that Dixon would be competent to stand trial within “two to
    six months.” Dr. Tuchler recommended treatment in a state
    hospital, and opined that Dixon “may become competent to
    stand trial.” Thereafter, the Superior Court determined that
    Dixon was not competent to stand trial and committed him to
    the Arizona State Hospital for competency restoration.
    Approximately six weeks later, a third psychiatrist, Dr.
    Marchildon, reported that Dixon was competent to stand trial,
    reasoning that Dixon’s “mental condition substantially
    differ[ed]” from the condition described by Drs. Bendheim
    6                      DIXON V. RYAN
    and Tuchler. Dr. Marchildon noted that Dixon’s affect was
    appropriate, his insight and judgment were satisfactory, and
    he “displayed no behavior or ideation which would indicate
    mental illness.” Dr. Marchildon further determined that
    Dixon understood the charges against him and the legal
    proceedings.
    Dixon thereafter appeared before the Superior Court,
    waived his right to a jury trial, and agreed the case should be
    determined on the submitted records. The court found Dixon
    not guilty of the assault by reason of insanity and ordered
    Dixon released pending civil proceedings on January 5, 1978.
    The next day, Deana Bowdoin was found dead in her
    apartment, strangled with a belt and stabbed several times.
    Investigators found semen in Deana’s vagina and on her
    underwear, but were unable at that time to match the DNA
    profile to a suspect.
    In June 1985, Dixon assaulted a Northern Arizona
    University student in Flagstaff, Arizona. State v. Dixon,
    
    735 P.2d 761
    , 762 (Ariz. 1987). Dixon was convicted of
    aggravated assault, kidnapping, sexual abuse, and four counts
    of sexual assault and was sentenced to seven consecutive life
    sentences. 
    Id. The victim
    initially reported the incident to
    the University Police Department. 
    Id. The University
    officers assisted in the investigation and transmitted an
    “attempt to locate” call after the victim provided a description
    of the assailant.
    In 2001, a police detective compared DNA recovered in
    the investigation of Bowdoin’s 1978 murder against a
    national database. The profile matched Dixon, then an
    DIXON V. RYAN                           7
    Arizona state inmate whose DNA had been collected in the
    1985 sexual assault investigation.
    B
    In November 2002, a grand jury indicted Dixon on the
    charge of first-degree premeditated murder, or, in the
    alternative, first-degree rape and felony murder, for
    Bowdoin’s murder.
    The State filed notice of its intent to seek the death
    penalty if Dixon were convicted of first-degree murder.
    Following the State’s notice of intent, public defenders Liles
    and Simpson were appointed to represent Dixon. For all
    capital defendants, Arizona law provided automatic
    prescreening evaluation for competency, sanity, and
    intellectual disability. Ariz. Rev. Stat. §§ 13–753 to 754.
    Dixon’s counsel objected to the prescreening evaluation,
    which was never performed.
    In July 2003, defense counsel informed the trial court it
    might take longer than usual to compile mitigation evidence
    because Dixon had spent his early life on the Navajo
    Reservation. Defense counsel estimated that the mitigation
    specialist would need a year to conduct a complete
    investigation. The court initially set the trial date for June 15,
    2004. Defense counsel later filed a Notice of Possible
    Insanity Defense.
    In April 2004, defense counsel estimated the mitigation
    investigation could be completed in five months if the case
    were assigned to a new specialist. The court granted the
    defense motion for a continuance on these grounds and
    vacated the June 2004 trial date. After a new mitigation
    8                     DIXON V. RYAN
    specialist was assigned to the case, the court extended the
    deadline for disclosure of mitigation evidence to January
    2005. In April 2005, defense counsel informed the court and
    the State that Dixon would not be pursuing an insanity
    defense.
    In October 2005, Dixon filed a motion for change of
    counsel, explaining that his counsel had informed Dixon that
    they could not file a motion he requested, despite previously
    agreeing to file the motion in exchange for his cooperation in
    the preparation of his defense. Dixon believed that the DNA
    evidence linking Dixon to the murder should be suppressed
    as fruit of the poisonous tree because it was obtained in
    connection with his 1985 assault conviction. The 1985
    conviction itself was invalid, Dixon believed, because the
    campus police lacked the authority to investigate. Defense
    counsel informed Dixon that they could not file the motion on
    Dixon’s behalf because Dixon’s theory was not viable. The
    court held a hearing, at which Dixon acknowledged that a
    different attorney may likewise refuse to file the motion, at
    which point he would proceed pro se. The court then denied
    the motion to substitute counsel, but advised Dixon that he
    could request to proceed pro se.
    In February 2006, Dixon moved to waive his right to
    counsel and to represent himself. The court granted Dixon’s
    request after engaging in a colloquy with Dixon regarding
    whether his request to represent himself was knowing,
    voluntary, and intelligent. The court questioned Dixon’s
    competency. Dixon informed the court that, although he
    previously underwent Rule 11 competency proceedings in
    1977, he was not aware of any current mental health issues
    that would prevent him from proceeding to trial. The court
    also asked Simpson, Dixon’s counsel at the time, if he knew
    DIXON V. RYAN                         9
    of any mental health issues “that would make this court’s
    decision as to whether to grant the waiver of right to counsel
    in jeopardy,” but Simpson denied knowledge of any reason
    why Dixon should not be allowed to waive counsel.
    Before deciding the motion, the court confirmed that
    Dixon wished to represent himself and give up his right to
    counsel, that Dixon understood trial counsel could “be of
    great benefit” to him, that Dixon had the right to an attorney
    and that the court could appoint an attorney if he could not
    afford one, that Dixon understood the charges against him,
    and that Dixon understood that the potential penalties for the
    crime included death or life imprisonment. The court
    determined that Dixon “knowingly, intelligently, and
    voluntarily waived” his right to be represented by an attorney,
    but appointed Simpson as advisory counsel. The court
    thereafter granted Dixon’s request for a paralegal and a
    mitigation specialist. Simpson served as advisory counsel
    until the court appointed Kenneth Countryman and Nathanial
    Carr III, who served as advisory counsel through Dixon’s trial
    and sentencing.
    Dixon subsequently filed a motion to suppress the DNA
    evidence linking him to the murder based on his theory that
    the campus officers lacked authority to investigate. The court
    denied the motion. Dixon filed a motion for change of judge
    based on the denial of the motion to suppress, which the court
    also denied. Dixon continued to pursue his theory in a special
    action, eventually seeking review, unsuccessfully, in the
    Arizona Supreme Court.
    When Dixon was granted permission to represent himself
    in March 2006, the court set the trial for October 18, 2006.
    In September 2006, Dixon informed the court his mitigation
    10                     DIXON V. RYAN
    evidence would not be ready for another nine months to a
    year, and the court continued the trial to June 25, 2007, “a
    date certain.” In May 2007, Dixon informed the court his
    mitigation evidence would not be ready for the June trial date
    and requested a continuance. The trial was rescheduled for
    August 2007.
    In late August 2007, Dixon moved for a continuance until
    the last week of January 2008. In support, Dixon raised the
    turnover among prior mitigation specialists, the loss of a
    number of documents compiled by the prior specialists,
    difficulties communicating with the current specialist and
    experts due to his incarceration, and overall delays due to his
    incarceration. The court set the trial date for September 13,
    2007, but subsequently reset the trial for November 13, 2007.
    On November 8, 2007, Dixon moved for a three-month
    continuance, until March 2008. Dixon attached a letter from
    the current mitigation specialist, Tyrone Mayberry, in which
    Mayberry informed Dixon that the mitigation investigation
    was not yet complete and that Dixon could not proceed to
    trial with the mitigation incomplete. Dixon also attached a
    letter addressed to his advisory counsel from the office of Dr.
    Gaughan, a psychologist. In the letter, Dr. Gaughan indicated
    that he had been unable to reach Dixon’s mitigation
    investigator or advisory counsel and expressed concern about
    the lack of communication given the seriousness of the case.
    The trial court denied Dixon’s motion, reasoning that the
    case was five years old and that the defense mitigation work
    had been “on going for well over four years.” Throughout
    trial, Dixon maintained a “standing objection” that he was not
    prepared to proceed.
    DIXON V. RYAN                         11
    At the time of Dixon’s trial, Maricopa County required in-
    custody defendants to wear leg brace and stun belt restraints
    while in court. Before trial, Dixon filed a motion to forgo use
    of the leg brace to enable him to move freely about the
    courtroom. The court denied Dixon’s motion based on the
    jail policy.
    The court warned Dixon of the possibility that the jury
    might infer the presence of the restraints, which “could be
    prejudicial,” and suggested that Dixon either remain seated in
    the presence of the jury or position himself at the podium
    before the jury entered the courtroom. Dixon again proposed
    that he wear the stun belt only, and not the leg brace, but the
    trial court rejected that option.
    At a conference with the court, Dixon acknowledged the
    risk that the jury might draw an inference from his movement
    that he might be wearing restraints, and the trial court
    determined that Dixon’s decision to use the podium to
    examine witnesses was knowing, voluntary, and intelligent.
    However, over the course of the trial, the court noted to
    Dixon several times that the outline of the stun belt was
    visible to the court. The judge instructed Dixon that he
    should try not to turn his back to the jury or bend over so as
    to minimize the visibility of the restraints.
    The judge also warned Dixon twice that the leg brace
    would cause him to walk in a stilted manner. Dixon
    expressed concern that if the officers failed to apply the brace
    to the same leg each day, the jury would “be confused . . . [if
    the jury were to] see I’m limping on my left side, and one day
    they see me limping on my right side.” The trial judge agreed
    to instruct the deputies to make sure that Dixon’s leg brace
    was consistently applied to Dixon’s right leg. Dixon alerted
    12                     DIXON V. RYAN
    the court one morning that deputies had brought only a left-
    leg brace. The trial judge agreed to change the brace out over
    the noon hour and to remind deputies to use the right-leg
    brace.
    C
    The jury convicted Dixon of both premeditated and felony
    murder on January 15, 2008. Prior to the penalty phase,
    Dixon again informed the court that his mitigation
    investigation was not complete. Dixon’s advisory counsel
    informed the court that, although the mitigation specialist still
    required additional time to complete his investigation of
    Dixon’s social history, a “substantial amount of mitigation
    . . . could be presented” regarding Dixon’s “appreciation for
    the wrongfulness of his conduct, family instability, parental
    instability, mental disorders, mental health and substance
    [abuse] issues.” Dixon’s advisory counsel informed the court
    that the defense had four experts approved and retained with
    regard to mental health and family history, as well as a
    number of documents regarding Dixon’s life. Advisory
    counsel represented to the court that they had informed Dixon
    that they would present the evidence with the help of the
    mitigation specialist, but that Dixon had chosen to present
    only one expert witness. Dixon asserted that he could not
    present mitigation evidence because the investigation was not
    complete. Dixon claimed that he had met with only one
    psychologist on two occasions and that the psychologist had
    been unprepared.
    At sentencing, the State argued that the death penalty was
    warranted because of four aggravating factors: (1) Dixon had
    previously been convicted of another offense for which,
    under Arizona law, a sentence of life imprisonment was
    DIXON V. RYAN                          13
    imposed; (2) Dixon committed the offense in an especially
    heinous manner; (3) Dixon committed the offense in an
    especially cruel manner; and (4) Dixon committed the offense
    in an especially depraved manner.
    Dixon presented only one mitigation witness. The
    witness, a former warden who reviewed Dixon’s prison
    record, testified that, in his opinion, the correctional system
    could manage Dixon if he were sentenced to life
    imprisonment.
    The jury determined that the State proved three
    aggravating factors beyond a reasonable doubt: (1) Dixon had
    been convicted of another offense for which, under Arizona
    law, a sentence of life imprisonment was imposed (the 1985
    assault of the NAU student); (2) Dixon committed the offense
    at issue in an especially heinous manner; and (3) Dixon
    committed the offense in an especially cruel manner. The
    jury unanimously determined that Dixon should be sentenced
    to death.
    The Arizona Supreme Court affirmed Dixon’s conviction
    and sentence on direct appeal. State v. Dixon (Dixon),
    
    250 P.3d 1174
    , 1185 (Ariz. 2011). The United States
    Supreme Court denied Dixon’s petition for certiorari.
    D
    Represented by counsel, Dixon filed a petition for post-
    conviction relief in the Arizona Superior Court. Dixon raised
    three claims: (1) that the Arizona Supreme Court deprived
    Dixon of his right to a fair sentencing and due process when
    it affirmed his death sentence; (2) that Dixon received
    ineffective assistance of counsel for his trial counsel’s failure
    14                    DIXON V. RYAN
    to challenge Dixon’s competency to waive counsel; and
    (3) that Dixon was deprived of effective representation from
    his advisory counsel for failure to challenge Dixon’s
    competency to waive counsel, inform the court of Dixon’s
    mental illness, and develop mitigation evidence relating to
    Dixon’s mental health.
    In support of his competency claims, Dixon offered the
    report of Dr. Toma. Between April and June 2012, Dr. Toma
    performed four neuropsychological and psychological
    evaluations of Dixon and diagnosed Dixon with
    schizophrenia, paranoid type, despite Dixon’s “adaman[ce]
    that he [did] not suffer from a mental illness.” Dr. Toma
    determined that Dixon was not capable of representing
    himself and that his competence should have been
    questioned. Dixon also offered a report by Dr. Patino, a
    psychiatrist who performed a psychiatric evaluation and who
    concluded that Dixon suffered from chronic paranoid
    schizophrenia, noting Dixon’s paranoia and poor insight.
    Dixon also submitted the report of Dr. Wu, who conducted a
    PET scan in October 2012. The results were consistent with
    schizophrenia and brain damage.
    The court dismissed the petition without an evidentiary
    hearing.    The court determined that trial counsel’s
    performance was neither deficient nor prejudicial and that
    Dixon had no constitutional right to effective assistance of
    advisory counsel. Dixon petitioned the Arizona Supreme
    Court for review; his petition was denied.
    E
    Dixon filed a petition for writ of habeas corpus in the
    United States District Court for the District of Arizona. The
    DIXON V. RYAN                          15
    district court denied the petition, vacated the stay of
    Arizona’s warrant of execution, and granted a certificate of
    appealability on three of Dixon’s thirty-six claims: (1) Claim
    1, alleging ineffective assistance of counsel for trial counsel’s
    failure to challenge Dixon’s competence to waive counsel
    without a hearing; (2) Claim 3(A), alleging that the trial court
    erred when it found Dixon competent to waive counsel; and
    (3) Claim 9, alleging that the trial court violated Dixon’s
    Eighth and Fourteenth Amendment rights when it denied his
    final motion for a continuance to allow him to develop further
    mitigation evidence.
    Dixon now appeals the district court’s denial of his
    habeas petition. In addition to the three certified issues,
    Dixon raises three uncertified arguments: (1) the trial court
    violated Dixon’s Sixth and Fourteenth Amendment rights
    when it required that he wear visible shackles in the presence
    of the jury without making an individualized determination
    that an essential state interest justified the restraints;
    (2) Dixon’s advisory standby counsel violated Dixon’s Sixth
    and Fourteenth Amendment rights by failing to challenge
    Dixon’s competency before the trial court; and (3) the trial
    court violated Dixon’s Sixth, Eighth, and Fourteenth
    Amendment rights by failing to instruct jurors during the
    penalty phase that they must find the aggravating factors
    outweighed the mitigating circumstances beyond a reasonable
    doubt in order to impose a sentence of death.
    II
    Dixon’s habeas petition is subject to review under the
    Antiterrorism and Effective Death Penalty Act of 1996
    (“AEDPA”), 28 U.S.C. § 2254(d). AEDPA limits “the
    availability of federal habeas relief . . . with respect to claims
    16                     DIXON V. RYAN
    previously ‘adjudicated on the merits’ in state-court
    proceedings.” Harrington v. Richter, 
    562 U.S. 86
    , 92 (2011).
    The statute “bars relitigation” of such claims subject only to
    two exceptions. 
    Id. at 98.
    Under AEDPA, federal habeas
    relief remains unavailable unless the state adjudication of the
    claim:
    (1) resulted in a decision that was contrary to,
    or involved an unreasonable application of,
    clearly established Federal law, as determined
    by the Supreme Court of the United States; or
    (2) resulted in a decision that was based on an
    unreasonable determination of the facts in
    light of the evidence presented in the State
    court proceeding.
    28 U.S.C. § 2254(d).
    Under § 2254(d), a state prisoner “must show that the
    state court’s ruling on the claim being presented in federal
    court was so lacking in justification that there was an error
    well understood and comprehended in existing law beyond
    any possibility for fairminded disagreement.” 
    Richter, 562 U.S. at 103
    .
    Under § 2254(d)(1), “an unreasonable application of
    federal law is different from an incorrect application of
    federal law.” 
    Id. at 101
    (citations omitted). So long as
    “fairminded jurists could disagree,” with respect to a state
    court’s determination that a claim lacks merit, federal habeas
    relief will not be granted. 
    Id. at 101
    (citation omitted).
    DIXON V. RYAN                        17
    Similarly, under § 2254(d)(2), a state court’s factual
    determination is “not unreasonable merely because the
    federal habeas court would have reached a different
    conclusion.” Wood v. Allen, 
    558 U.S. 290
    , 301 (2010).
    “[Section] 2254(d)(2) requires that [the court] accord the
    state trial court substantial deference.” Brumfield v. Cain,
    
    135 S. Ct. 2269
    , 2277 (2015). “A state court’s factual
    findings are unreasonable if ‘reasonable minds reviewing the
    record’ could not agree with them.” Ayala v. Chappell,
    
    829 F.3d 1081
    , 1094 (9th Cir. 2016) (quoting 
    Brumfield, 135 S. Ct. at 2277
    ).
    Even where the state court unreasonably applied federal
    law or unreasonably determined a critical fact, the petitioner
    is not entitled to relief unless the habeas court “has ‘grave
    doubt about whether’” the constitutional error “had [a]
    ‘substantial and injurious effect or influence’” on the jury’s
    verdict; the petitioner must establish “actual prejudice.”
    Davis v. Ayala, 
    135 S. Ct. 2187
    , 2197–98 (2015) (citations
    omitted).

    A
    The district court properly held that Dixon’s Sixth
    Amendment right to effective assistance of counsel was not
    violated when his trial counsel elected not to challenge
    Dixon’s competency to waive counsel, despite counsel’s
    knowledge that Dixon had a history of mental health issues.
    Dixon contends that, but for counsel’s deficient performance,
    there is a reasonable probability that he would not have been
    allowed to waive counsel and the result of the proceedings
    would have been different. Dixon argues that the Arizona
    18                     DIXON V. RYAN
    Superior Court’s denial of his petition for post-conviction
    relief (“PCR”) thus rested on both an unreasonable
    application of the clearly established ineffective assistance of
    counsel standard and an unreasonable determination of facts.
    An ineffective assistance of counsel claim is measured by
    the standard set forth in Strickland v. Washington, 
    466 U.S. 668
    (1984). To prevail under Strickland, a petitioner “must
    show that counsel’s performance was deficient” and that “the
    deficient performance prejudiced” the petitioner. 
    Id. at 687.
    This inquiry is “highly deferential.” 
    Id. at 689.
    Strickland’s first prong requires a showing that counsel’s
    performance “fell below an objective standard of
    reasonableness” at the time of the trial. 
    Id. at 688.
    Defense
    counsel is “strongly presumed to have rendered adequate
    assistance” and, for a petitioner to prevail, must have “made
    errors so serious that counsel was not functioning as the
    ‘counsel’ guaranteed . . . by the Sixth Amendment.” 
    Id. at 687,
    690. With respect to the prejudice prong, a petitioner
    must prove that “there is a reasonable probability that, but for
    counsel’s unprofessional errors, the result of the proceeding
    would have been different.” 
    Id. at 694.
    “A reasonable
    probability is a probability sufficient to undermine confidence
    in the outcome.” 
    Id. More specifically,
    to succeed on a claim that counsel was
    ineffective for failing to move for a competency hearing,
    there must be “sufficient indicia of incompetence to give
    objectively reasonable counsel reason to doubt defendant’s
    competency” and “a reasonable probability that the defendant
    would have been found incompetent.” Hibbler v. Benedetti,
    
    693 F.3d 1140
    , 1149–50 (9th Cir. 2012) (quoting Stanley v.
    Cullen, 
    633 F.3d 852
    , 862 (9th Cir. 2011)).
    DIXON V. RYAN                         19
    In the AEDPA context, moreover, the “pivotal question
    is whether the state court’s application of the Strickland
    standard was unreasonable,” which is “different from asking
    whether defense counsel’s performance fell below
    Strickland’s standard.” 
    Richter, 562 U.S. at 101
    . Under this
    “doubly deferential” standard, the court asks “whether it is
    possible fairminded jurists could disagree that [the state
    court’s decision is] inconsistent with the holding in a prior
    decision of [the United States Supreme] Court.” 
    Id. at 102.
    Accordingly, “[e]stablishing that a state court’s application of
    Strickland was unreasonable under § 2254(d) is . . . difficult.”
    
    Richter, 562 U.S. at 105
    .
    The Arizona Superior Court correctly identified
    Strickland as the applicable standard by which to measure
    Dixon’s ineffective assistance of counsel claim. The court
    ruled that Dixon had not demonstrated either deficient
    performance or prejudice. In reaching this conclusion, the
    court—presided over by the same judge who presided over
    the Bowdoin murder trial—explained that it was aware at the
    time Dixon moved to waive counsel “of information that
    placed [Dixon’s] mental health at issue,” thus “counsel could
    not have been ineffective in failing to give the [c]ourt
    information it already had.” The court further recalled
    Dixon’s acknowledgment during the colloquy of his 1977
    Rule 11 competency proceedings, and noted that both Dixon
    and counsel agreed that Dixon “had no mental problems that
    would place his ability to waive the right to counsel in
    jeopardy.” The court also noted that Dixon “was adamant
    that he would not submit to [a competency] evaluation,” and
    the court observed Dixon “to be able to adequately advance
    his positions” and to be “cogent in his thought processes,
    lucid in argument, and always able to respond to all questions
    with appropriate answers.” Ultimately, the court found that
    20                    DIXON V. RYAN
    Dixon’s “waiver of counsel was a knowing, voluntary, and
    intelligent decision on the part of a competent individual.”
    To determine whether the Arizona court’s application of
    Strickland was unreasonable, we look to evidence in the
    record of counsel’s performance to decide “whether there is
    any reasonable argument that counsel satisfied Strickland’s
    deferential standard.” 
    Id. at 105.
    Specifically, we examine
    the record to decide whether it was reasonable for the Arizona
    Superior Court to determine that the record lacked “sufficient
    indicia of incompetence to give objectively reasonable
    counsel reason to doubt defendant’s competency” or “a
    reasonable probability that the defendant would have been
    found incompetent.” 
    Hibbler, 693 F.3d at 1149
    –50.
    Although two doctors opined in 1977 that Dixon suffered
    from schizophrenia and was not competent to stand trial,
    nearly 30 years passed between those evaluations and
    Dixon’s 2006 waiver of counsel. Further, the two evaluations
    cited Dixon’s depression and indicated that competency
    restoration was possible. In fact, a few weeks after the 1977
    incompetency determination, a third psychiatrist determined
    that Dixon’s mental health status had significantly changed,
    that Dixon had been restored to competency, and that Dixon
    was competent to stand trial. With respect to the 1985 assault
    and resulting conviction, it does not appear from the record
    that Dixon’s competency or mental health was at issue. The
    1977 evaluations and the 1978 not guilty by reason of
    insanity verdict thus shed little light on Dixon’s competence
    at the time he chose to waive counsel in 2006.
    In fact, the record contains no evidence of competency
    issues at any time throughout the course of these proceedings.
    The record instead demonstrates that, at the time Dixon
    DIXON V. RYAN                        21
    sought to represent himself, Dixon understood the charges
    against him and the potential sentences, he was able to
    articulate his legal positions and respond to questions with
    appropriate answers, and that Dixon demonstrated rational
    behavior. As to Dixon’s continued interest in the DNA
    suppression issue (which Dixon cites as an indication that he
    was not competent to waive counsel), Dixon’s interest in the
    issue was not so bizarre or obscure as to suggest that Dixon
    lacked competence.
    The 2012 reports Dixon produced in support of his PCR
    petition do not compel a contrary conclusion. In addition,
    because they are necessarily retrospective, they likewise fail
    to illuminate Dixon’s competence during the relevant time
    period. Dr. Toma’s opinion, in particular, that Dixon was not
    capable of representing himself, does not render unreasonable
    the Arizona court’s conclusions in light of a record that
    demonstrates that Dixon had mental health issues but had
    previously been restored to competency.
    The record supports the conclusions of the state court.
    The record reflects that Dixon’s prior temporary
    incompetence was depression-related and readily apparent in
    Dixon’s demeanor, communication, and affect. Dixon
    displayed no such issues before the trial court. When the
    evidence of Dixon’s prior mental health issues is examined
    through AEDPA’s deferential lens, the state court’s
    application of Strickland was not unreasonable, because the
    evidence before the trial court was temporally remote and
    inconclusive. Likewise, although reasonable minds may
    disagree about the import of Dixon’s past incompetency, the
    record does not contain any evidence that Dixon was not
    competent between 2002 and 2006, the time period
    particularly relevant to the murder trial and Dixon’s waiver
    22                     DIXON V. RYAN
    of counsel. Thus, the record demonstrates that the Arizona
    Superior Court did not rely on an unreasonable determination
    of the facts. We therefore affirm the district court’s denial of
    Dixon’s petition for a writ of habeas corpus as to the first
    certified issue.
    B
    The district court properly concluded that Dixon’s due
    process rights were not violated by the state trial court’s
    failure to hold a competency hearing sua sponte. Dixon
    argues that substantial evidence before the court raised a good
    faith doubt about his competence and that the trial court’s
    failure to hold a hearing before finding him competent to
    represent himself violated his right to due process. Dixon
    also argues that the post-conviction court failed to hold an
    evidentiary hearing, contrary to clearly established federal
    law, and failed to acknowledge expert reports which indicated
    that he suffered from some form of schizophrenia, brain
    damage, and other disorders, reflecting an unreasonable
    determination of the facts. Dixon again relies on the two
    1977 competency evaluations, the 1978 not guilty by reason
    of insanity verdict, and his continued pursuit of the motion to
    suppress in support of his argument.
    Although a criminal defendant has a Sixth Amendment
    right to self-representation, the defendant must be competent
    to waive counsel. Godinez v. Moran, 
    509 U.S. 389
    , 396
    (1993) (citing Johnson v. Zerbst, 
    304 U.S. 458
    , 468 (1938)).
    The standard a court must apply to a defendant’s request for
    self-representation differs from the standard for competence
    to stand trial. United States v. Ferguson, 
    560 F.3d 1060
    ,
    1061–62, 1067–68 (9th Cir. 2009) (citing Indiana v.
    Edwards, 
    554 U.S. 164
    , 176–77 (2008)); compare Godinez,
    DIXON V. RYAN                        
    23 509 U.S. at 396
    (competence to stand trial requires a
    “sufficient present ability to consult with his lawyer with a
    reasonable degree of rational understanding” and “a rational
    as well as factual understanding of the proceedings against
    him” (quoting Dusky v. United States, 
    362 U.S. 402
    , 402
    (1960) (per curiam))).
    The Supreme Court has not set forth a specific standard
    for a criminal defendant’s competence to exercise his right to
    self-representation, however, instead leaving the
    determination of whether the defendant is competent to
    conduct trial proceedings to the trial court’s discretion.
    
    Edwards, 554 U.S. at 175
    –76. The Edwards court reasoned
    that the trial judge “will often prove best able to make more
    fine-tuned mental capacity decisions, tailored to the
    individualized circumstances of a particular defendant.” 
    Id. at 177.
    Thus, a defendant may be in the “gray area,” where
    he is competent to stand trial, but suffers from a mental
    impairment such that he is not competent to conduct trial
    proceedings. 
    Id. at 172–77.
    Due process “requires that a state court initiate a hearing
    on the defendant’s competence to waive counsel whenever it
    has or should have a good faith doubt about the defendant’s”
    competence. Harding v. Lewis, 
    834 F.2d 853
    , 856 (9th Cir.
    1987). “A good faith doubt exists when there is substantial
    evidence of incompetence.” 
    Id. (citing United
    States v.
    Veatch, 
    674 F.2d 1217
    , 1223 (9th Cir. 1981)). Evidence of
    incompetence “includes, but is not limited to, a history of
    irrational behavior, medical opinion, and the defendant’s
    behavior at trial.” 
    Id. Dixon cannot
    overcome the AEDPA deference that we
    are required to apply to the Arizona Superior Court’s
    24                    DIXON V. RYAN
    rejection of this argument. Although the record demonstrates
    Dixon’s history of mental health and competency issues, the
    record also contains evidence of Dixon’s competence at the
    time he moved to represent himself, as discussed above.
    Even under a higher competency standard for self-
    representation, the PCR court’s determination without a
    hearing that Dixon was competent to waive counsel and
    represent himself was not an unreasonable determination of
    the facts, nor was it contrary to clearly established federal
    law. Dixon’s actions before the trial court indicated that he
    understood the consequences of waiving his right to counsel
    and that he possessed sufficient intelligence and competence
    to participate in the proceedings. Dixon was responsive and
    rational before the trial court, and he expressed himself
    effectively. The court noted that Dixon was able to articulate
    and advance his positions and to understand and respond
    appropriately to questions. Although there was evidence that
    Dixon lacked competence to stand trial in 1977, the record
    does not demonstrate that this evidence of past incompetency
    presents “substantial evidence” giving rise to “a good faith
    doubt” as to Dixon’s competency to represent himself in
    2006. We affirm the district court’s denial of Dixon’s
    petition as to the second certified issue.
    C
    The district court properly held that the Arizona Supreme
    Court’s opinion concluding that the trial court did not abuse
    its discretion in denying Dixon’s final continuance motion
    was neither contrary to, nor an unreasonable application of,
    clearly established federal law. The court also did not err in
    holding that the Arizona Supreme Court’s determination did
    not rest on an unreasonable determination of the facts.
    DIXON V. RYAN                        25
    Dixon raised these claims on direct appeal to the Arizona
    Supreme Court, and the Arizona Supreme Court rejected the
    claims on the merits. That court stated that “Dixon was given
    more than four years to develop mitigation” and that the trial
    court did not err in considering the rights of the victim’s
    parents and Dixon’s right to a speedy disposition. Dixon
    argues that the Arizona Supreme Court’s conclusion is not
    entitled to AEDPA deference because it (1) relied on
    inaccurate representations made by Dixon’s advisory counsel
    regarding the status of Dixon’s mitigation development;
    (2) omitted evidence that Dixon’s mitigation case was not
    close to being complete; and (3) failed to address the
    impediments Dixon faced in developing his mitigation case.
    1
    Dixon argues that the Arizona Supreme Court’s decision
    was contrary to, and unreasonably applied, clearly established
    federal law because it ignored the specific circumstances
    Dixon faced and precluded Dixon from presenting mitigating
    evidence that a life sentence, rather than the death penalty,
    was warranted. Specifically, Dixon asserts that the Arizona
    Supreme Court’s decision violated Supreme Court precedent
    by focusing primarily on the amount of time during which the
    mitigation investigation had been ongoing, while ignoring the
    individual impediments Dixon faced in preparing his
    mitigation case. Clearly established federal law regarding the
    denial of a continuance requires that the state court consider
    the relevant circumstances before denying a continuance.
    Ungar v. Sarafite, 
    376 U.S. 575
    , 589–90 (1964). However,
    only “an unreasoning and arbitrary ‘insistence upon
    expeditiousness in the face of a justifiable request for delay’
    violates the right to the assistance of counsel.” Morris v.
    26                     DIXON V. RYAN
    Slappy, 
    461 U.S. 1
    , 11–12 (1983) (quoting 
    Ungar, 376 U.S. at 589
    ).
    The Arizona Supreme Court’s conclusion that the trial
    court appropriately considered Dixon’s circumstances in
    denying the continuance does not amount to an unreasonable
    application of Morris or Ungar. Although the trial court cited
    the overall length of the case in denying the motion, the trial
    court also cited the interests of the victims, and the mitigation
    investigation done by prior counsel and mitigation specialists.
    The trial court referenced the overall length of the case and
    weighed the timely resolution of the case, among other
    factors, so the denial was not an “unreasoning” or “arbitrary
    ‘insistence’” on an expeditious resolution of the case.
    
    Morris, 461 U.S. at 11
    (quoting 
    Ungar, 376 U.S. at 589
    ).
    As to clearly established federal law governing the role of
    mitigating evidence in capital sentencing, under the Eighth
    and Fourteenth Amendments, a sentencer in a capital case
    may “not be precluded from considering, as a mitigating
    factor, any aspect of a defendant’s character or record and
    any circumstances of the offense that the defendant proffers
    as a basis for a sentence less than death.” Lockett v. Ohio,
    
    438 U.S. 586
    , 604 (1978) (emphasis omitted); see also Abdul-
    Kabir v. Quarterman, 
    550 U.S. 233
    , 246 (2007); Eddings v.
    Oklahoma, 
    455 U.S. 104
    , 109 (1982). Because Dixon
    contends that the denial of the final motion to continue cut
    short the mitigation investigation and denied him the
    opportunity to further investigate potential areas relevant to
    mitigation, we consider whether the denial of the continuance
    precluded the jury from considering or giving effect to any
    relevant mitigation evidence.
    DIXON V. RYAN                        27
    Dixon himself determined what mitigation evidence to
    present to the jury and was given an opportunity to present
    the evidence during the penalty phase. Dixon acknowledged
    that he did not want to present mitigating evidence related to
    his family history and instead opted to call only one expert
    witness to present evidence about Dixon’s history in prison
    and the ability of the prison system to control him. Although
    his mitigation investigation may have been incomplete, the
    denial of the final continuance did not preclude the jury from
    considering or giving mitigating weight to any category of
    evidence in the way the sentencers were precluded from
    weighing the mitigating evidence in Lockett, Abdul-Kabir,
    and Eddings.
    As distinguished from the cases cited by Dixon, the jury
    here was not precluded, as a matter of law, from considering
    any mitigation evidence. Neither the sentencing statute, nor
    the trial judge’s instructions, prevented the jury from
    considering mitigating evidence or giving mitigating weight
    to Dixon’s character and record or the circumstances of the
    offense. See 
    Lockett, 438 U.S. at 593
    –94, 604–06 (holding
    that the Ohio death penalty statute, which required imposition
    of the death penalty once a defendant was found guilty of
    aggravated murder with at least one of seven specified
    aggravating factors, unless one of three specified mitigating
    factors was established by a preponderance of the evidence,
    violated the Eighth and Fourteenth Amendments because the
    statute limited the range of mitigating factors that the
    sentencer could consider); see also 
    Abdul-Kabir, 550 U.S. at 237
    –244, 263–64 (holding that, although defendant presented
    mitigating evidence, the trial judge’s refusal to give
    defendant’s requested instructions prevented the jury from
    considering the mitigating evidence); 
    Eddings, 455 U.S. at 110
    , 112–14 (the court’s determination that, as a matter of
    28                     DIXON V. RYAN
    law, it was unable to consider Eddings’ violent family
    history, had the same effect as an instruction to the jury to
    disregard Eddings’ mitigating evidence, and violated the
    Eighth and Fourteenth Amendments by precluding the
    sentencer from considering Eddings’ character).
    2
    The district court also properly concluded that the
    Arizona Supreme Court’s determination that the trial court
    did not abuse its discretion in denying the final request for a
    continuance did not rest on an unreasonable determination of
    the facts. In his final motion to continue, Dixon detailed a
    number of reasons why a three month continuance was
    necessary. Specifically, Dixon highlighted a change in
    mitigation specialists, delays caused by his incarceration, an
    overall inability to access legal resources while incarcerated,
    and an inability to schedule interviews with potential
    witnesses. In support of his motion, Dixon attached a letter
    from his current mitigation specialist which expressed the
    view that there was “no way ethically to proceed to trial.”
    The specialist cited delays in reviewing mitigation documents
    and interviewing witnesses and the appointment of expert
    witnesses.
    Dixon now argues that the Arizona Supreme Court’s
    decision is premised on an unreasonable factual
    determination because the court relied on an inaccurate
    representation made by Dixon’s advisory counsel that a
    substantial amount of mitigation evidence had already been
    prepared, omitted evidence that the mitigation case was not
    complete, and unreasonably determined that the trial court
    appropriately considered Dixon’s interests.
    DIXON V. RYAN                         29
    Although Dixon asserted that he faced a number of delays
    in and impediments to completing a thorough mitigation
    investigation and that the mitigation specialist indicated he
    had not yet completed the investigation, the Arizona Supreme
    Court did not rely on an unreasonable determination of the
    facts in concluding that the trial court did not abuse its
    discretion by denying the continuance. Rather, the court
    relied on the representations made to it by Dixon’s advisory
    counsel as to the mitigation evidence available. Although the
    advisory counsel’s representations conflicted with Dixon’s
    and the mitigation specialist’s opinions, that the Arizona
    Supreme Court gave greater weight to the advisory counsel’s
    representations does not amount to an unreasonable
    determination of the facts. Under the relevant standard,
    reasonable minds might disagree as to which statements the
    court should have credited, especially because advisory
    counsel recognized the incomplete status of the investigation
    in their representations regarding how much of the mitigation
    investigation had been completed.
    The Arizona Supreme Court also acknowledged the many
    continuances granted by the trial court to allow Dixon to
    develop more mitigation evidence, the overall length of the
    case, Dixon’s interests, and the victims’ rights. Consideration
    of these factors is supported by the record, and the finding
    that the trial court did not abuse its discretion in denying the
    continuance was not unreasonable. For its part, the trial court
    reviewed a chronology of the case, the mitigation specialist’s
    work on the case, and the victims’ objections to a
    continuance. The trial court and the Arizona Supreme Court
    ultimately gave more weight to the overall length of the
    case, the victim’s interests, and the advisory counsel’s
    representations than to Dixon’s claimed delays and
    impediments. The PCR court’s ultimate determination that
    30                     DIXON V. RYAN
    the trial court’s decision was not an abuse of discretion did
    not rest on an unreasonable determination of the facts.

    When the district court issues a COA on some, but not all,

    could resolve the issues in a different manner; or that the
    questions are adequate to deserve encouragement to proceed
    further.” Lambright v. Stewart, 
    220 F.3d 1022
    , 1025 (9th Cir.

    We conclude that Dixon has satisfied this standard as to
    his claim that the state trial court denied his constitutional
    right to a fair trial by requiring him to wear restraints during
    trial. 28 U.S.C. § 2253(c)(2). We deny the motion to expand
    the COA as to the other issues.

    “The law has long forbidden routine use of visible
    shackles during the guilt phase; it permits a State to shackle
    a criminal defendant only in the presence of a special need.”
    Deck v. Missouri, 
    544 U.S. 622
    , 626 (2005). The
    Constitution also “forbids the use of visible shackles during
    the penalty phase, as it forbids their use during the guilt
    phase, unless that use is ‘justified by an essential state
    interest’—such as the interest in courtroom security—specific
    to the defendant.” 
    Id. at 624
    (quoting Holbrook v. Flynn,
    
    475 U.S. 560
    , 568–69 (1986)). This “constitutional
    requirement, however, is not absolute.” 
    Id. at 633.
    In the
    exercise of his or her discretion, a judge may take into
    account “special circumstances, including security concerns,
    that may call for shackling . . . [b]ut any such determination
    must be case specific.” 
    Id. The Arizona
    Supreme Court acknowledged that the trial
    court failed to make the requisite “particularized finding of
    the need for security measures” before requiring Dixon to
    wear stun belt and leg brace restraints. 
    Dixon, 250 P.3d at 1180
    .      Nevertheless, the Arizona Supreme Court
    determined that Dixon could not succeed on his restraint
    claim because he failed to show that the jury actually saw the
    restraints. 
    Id. at 1181.
    Furthermore, the court determined
    that any improperly-imposed visible restraint would have
    constituted harmless error because it was “clear beyond a
    reasonable doubt that a rational jury would have found the
    defendant guilty absent the error.” 
    Id. (quoting Hymon
    v.
    State, 
    111 P.3d 1092
    , 1099 (Nev. 2005)).
    The Arizona Supreme Court adjudicated Dixon’s guilt-
    phase shackling claims on the merits on direct appeal. Dixon,

    250 P.3d 1179
    –82. We treat Dixon’s penalty-phase restraints
    claims as adjudicated on the merits as well; although the
    Arizona Supreme Court did not specifically address them,
    they are identical to Dixon’s guilt-phase claims. In addition,
    “[i]f a federal claim [is] presented to the state court and the
    state court denie[s] all relief without specifically addressing
    the federal claim, ‘it may be presumed that the state court
    adjudicated the claim on the merits in the absence of any
    indication or state-law procedural principles to the contrary.’”
    Amado v. Gonzalez, 
    758 F.3d 1119
    , 1131 (9th Cir. 2014)
    (quoting 
    Richter, 562 U.S. at 99
    ). Section 2254(d) applies
    “even where there has been a summary denial.” Cullen v.
    Pinholster, 
    563 U.S. 170
    , 187 (2011). Habeas relief is
    therefore available on these claims only if Dixon can
    overcome AEDPA deference. Dixon argues that he has
    overcome AEDPA under both § 2254(d)(1) and (d)(2).

    Dixon contends that the Arizona Supreme Court
    contravened clearly established federal law “[b]y placing the
    burden on Dixon to prove that his leg restraint was not visible
    and that he was therefore not prejudiced by his erroneous
    shackling.”
    The Arizona Supreme Court correctly identified Deck as
    controlling federal authority and framed the “central issue” as
    “whether the restraints” used on Dixon “were visible” to the
    jury. The court determined that Dixon provided “no evidence
    . . . that the jury either saw the brace or inferred that Dixon
    wore one” and “the reported decisions correctly treat a leg
    brace worn under clothing as not visible in the absence of
    evidence to the contrary.” Dixon argues that requiring him to
    prove that the jury saw the restraints impermissibly shifted
    DIXON V. RYAN                              33
    the burden of the harmless error analysis to him, contravening
    Chapman v. California, 
    386 U.S. 18
    (1967).
    Dixon relies on Dyas v. Poole, 
    317 F.3d 934
    (9th Cir.
    2003) (per curiam), to support his claim. In Dyas, “[t]he
    California Court of Appeal held that keeping Dyas shackled
    during trial was constitutional error . . . [but] then ruled . . .
    that the error was harmless because the trial court had ‘found’
    that the jurors would not be able to see the shackles from the
    jury box.” 
    Id. at 936.
    We held that “the state court of appeal
    held against Dyas the absence of evidence of what the jury
    could see, which was contrary to the requirement of
    
    Chapman, 386 U.S. at 24
    , that the prosecution bear the
    burden of showing harmlessness beyond a reasonable doubt.”
    
    Dyas, 317 F.3d at 937
    .
    The State inarguably bears the burden to prove
    harmlessness. 
    Chapman, 386 U.S. at 24
    . Dixon’s reliance
    on Dyas, however, improperly conflates the inquiry as to
    whether the restraints were visible to the jury—which is
    relevant to whether Dixon has demonstrated a constitutional
    violation under Deck—with the harmless error inquiry, which
    places the burden on the government to prove that the jury
    would have found Dixon guilty absent the error. See 
    Deck 544 U.S. at 635
    .1 While visibility is relevant to both
    considerations, the question here is whether Dixon was
    prejudiced under Deck by the jury’s ability to see the
    1
    Dyas itself is not relevant to our analysis of whether the Arizona
    Supreme Court unreasonably applied Supreme Court precedent because,
    as the Supreme Court has “repeatedly pointed out, circuit precedent does
    not constitute clearly established Federal law, as determined by the
    Supreme Court.” Kernan v. Cuero, 
    138 S. Ct. 4
    , 9 (2017) (quoting Glebe
    v. Frost, 
    135 S. Ct. 429
    , 430 (2014)).
    34                     DIXON V. RYAN
    restraints, which Dixon must show to succeed on his claim.
    The Arizona Supreme Court’s determination that Dixon was
    not prejudiced because the jury did not see the restraints was
    neither an unreasonable determination of the facts nor was its
    application of Deck contrary to clearly established federal
    law. In the alternative, the Arizona Supreme Court held that
    any error under Deck was harmless, and the Arizona Supreme
    Court did not base its harmless error determination on a lack
    of visibility. Rather, the court proceeded to analyze harmless
    error despite its previous determination that the restraints
    were, in fact, not visible to the jury (and therefore there was
    no violation of “the rule announced in Deck”). 
    Dixon, 250 P.3d at 1181
    . The Court determined that “the DNA
    evidence” and “the circumstances of the crime” rendered any
    error resulting from the improper imposition of “visible
    restraints” harmless. 
    Id. The Arizona
    Supreme Court did not apply Chapman in an
    objectively unreasonable manner. See 
    Ayala, 135 S. Ct. at 2198
    . Under § 2254(d)(1), “an unreasonable application of
    federal law is different from an incorrect application of
    federal law.” 
    Richter, 562 U.S. at 101
    (citation omitted). So
    long as “fairminded jurists could disagree,” with respect to a
    state court’s determination that a claim lacks merit, federal
    habeas relief will not be granted. 
    Id. Under this
    standard,
    because the Arizona Supreme Court engaged in a harmless
    error analysis that assumed visibility, Dixon’s claim fails.
    2
    The district court properly concluded that the Arizona
    Supreme Court’s factual conclusions were not unreasonable.
    “A state court’s factual findings are unreasonable if
    DIXON V. RYAN                         35
    ‘reasonable minds reviewing the record’ could not agree with
    them.” 
    Ayala, 829 F.3d at 1094
    (citation omitted).
    The Arizona Supreme Court determined that it should
    treat restraints worn under clothing “as not visible in the
    absence of evidence to the contrary.” 
    Dixon, 250 P.3d at 1181
    . The court explained, with regard to the leg brace, that
    there was “no evidence” that the brace was visible or that the
    jury inferred that Dixon was restrained. 
    Id. As to
    the stun
    belt, the court noted Dixon’s failure to object to the stun belt
    below and explained that, under fundamental error review,
    Dixon “must show that [the stun belt] was visible to the jury.”
    
    Id. The court
    concluded that Dixon “ha[d] not met that
    burden.” 
    Id. Dixon argues
    that these factual determinations
    “patently ignored evidence in the state court record that both
    the stun belt and leg restraint were, indeed, visible.”
    Dixon argues that evidence in the record supports that the
    jury saw or inferred that he was wearing a leg brace. The
    only evidence in the record regarding the effect of the leg
    brace on Dixon’s gait appears where the court twice warned
    Dixon that the leg brace could cause him to walk “in some
    sort of stilted fashion” in front of the jury. Dixon expressed
    concern about the jury’s observing him limping on different
    legs depending on which leg the brace was applied to, which
    the court attempted to mitigate by asking deputies to
    consistently use a right leg brace.
    None of the evidence presented in the state court
    proceeding establishes that the state court made an
    unreasonable factual determination when it ruled that “no
    evidence” suggested that the brace was visible or that the jury
    inferred restraint. 
    Dixon, 250 P.3d at 1181
    . First, nowhere in
    the record does any party suggest or comment that the leg
    36                     DIXON V. RYAN
    brace itself actually was visible. Second, the record suggests
    no more than the possibility that the jury may have seen
    Dixon limp. Even if the jury saw Dixon limp inconsistently,
    this does not render the Arizona Supreme Court’s
    determination unreasonable, because “reasonable minds
    reviewing the record” could disagree that this evidence
    supports a conclusion that the jurors did not actually infer the
    presence of the brace. 
    Ayala, 829 F.3d at 1094
    (citation
    omitted).
    Dixon likewise argues that the trial judge’s repeated
    observations regarding the visibility of the stun belt
    constituted factual determinations deserving of deference and
    render the Arizona Supreme Court’s subsequent factual
    determination unreasonable.
    The Arizona Supreme Court acknowledged the trial
    judge’s comments that, when Dixon turned his back towards
    the jury and bent over, the outline of the stun belt protruded,
    and the belt was “very” and “readily” visible, and the trial
    court cautioned Dixon several times that it was apparent that
    Dixon was wearing the belt. The Arizona Supreme Court
    dismissed these comments as “speculat[ion] that jurors might
    be able to see” the belt. 
    Dixon, 250 P.3d at 1181
    . The court
    then determined only that Dixon had not demonstrated that
    “the jury actually saw the belt or inferred its presence.” 
    Id. This does
    not amount to an unreasonable factual
    determination based on the evidence available to the state
    court such that “‘reasonable minds reviewing the record’
    could not agree with [it].” 
    Ayala, 829 F.3d at 1094
    (citation
    omitted).
    DIXON V. RYAN                          37
    For the foregoing reasons, Dixon cannot overcome
    AEDPA deference on the restraints claims, and we affirm the
    district court’s denial of the petition as to this issue.
    V
    We affirm the district court’s denial of the writ of habeas
    corpus. We expand the COA to include the question of
    whether Dixon’s constitutional rights were violated at trial
    through use of restraints, but affirm the district court’s denial
    of the writ on that issue. We decline to expand the COA
    further.
    AFFIRMED.
