    Appeal from the United States District Court
    for the Southern District of Florida
    ________________________
    (July 11, 2012)
    Before DUBINA, Chief Judge, and HULL and MARCUS, Circuit Judges.
    HULL, Circuit Judge:
    Florida death row inmate Duane Eugene Owen appeals the district court’s
    denial of his 
    28 U.S.C. § 2254
     petition for a writ of habeas corpus. After review
    and oral argument, we affirm.
    I. BACKGROUND
    Owen is under two death sentences for two murders in 1984, for which he
    was separately tried, convicted, and sentenced. Owen’s March 24, 1984 murder of
    Karen Slattery in Delray Beach, Florida, is the subject of this appeal. Owen’s May
    28, 1984 murder of Georgianna Worden in Boca Raton, Florida, is the subject of
    this Court’s decision in Owen v. Secretary for the Department of Corrections, 
    568 F.3d 894
     (11th Cir. 2009).
    The Slattery and Worden cases are legally distinct but factually similar. In
    each murder, Owen broke into a private home late at night, removed most of his
    clothing, sexually assaulted the victim, and brutally murdered the victim (he killed
    Slattery with a knife, Worden with a hammer). Delray Beach and Boca Raton
    police worked together to investigate the murders and, after Owen’s arrest,
    questioned Owen about both murders. Owen confessed to both murders on the
    same day.
    We discuss the Worden murder, investigation, and legal proceedings where
    necessary for context. Otherwise, we confine our discussion to the Slattery
    2
    murder case on appeal here.
    A.     Slattery Murder Investigation
    On the evening of March 24, 1984, victim Karen Slattery, who was 14 years
    old, was babysitting for William and Carolyn Helm at their home in Delray Beach.
    Just after midnight, the Helms returned home and found a large pool of blood in
    the kitchen, with drag marks leading toward the master bedroom. The Helms
    called the police, who found Slattery’s body in the master bedroom. Slattery’s
    body had 18 knife wounds and showed evidence of sexual assault.1 There were
    eight stab wounds on Slattery’s back, six stab wounds on her neck, and four
    cutting wounds on the front of her throat. The Helm children, ages three and
    seven, were in their own bedroom, asleep and unharmed. Police discovered that
    Slattery’s killer entered the Helms’ home by cutting the screen to a window in the
    master bedroom. Police found a bloody footprint made by the killer’s bare or
    stockinged right foot.
    On May 29, 1984, Boca Raton police arrested Owen on unrelated burglary
    charges and outstanding warrants for failure to appear. See Owen v. State, 
    560 So. 1
    A vaginal swab tested positive for semen. Based on the state of serology analysis
    available at the time, police “found nothing in the semen evidence to indicate or to eliminate
    Duane Owen as a contributor to the semen.” However, in the late 1990s, new DNA testing of the
    semen showed that the semen found in Slattery’s body contained DNA markers linking it to
    Owen, who is Caucasian, and only 1 out of 690 million Caucasian males would have those same
    DNA markers.
    3
    2d 207, 209 (Fla. 1990) (“Owen I”), abrogated in part by State v. Owen, 
    696 So. 2d 715
     (Fla. 1997) (“Owen III”). On that same day, Worden’s body was found in
    Boca Raton.
    Over the next three weeks, police questioned Owen about various crimes
    they believed Owen committed. The police questioning, which was videotaped,
    occurred over six days: June 3, 6, 7, 8, 18, and 21, 1984. As the Florida Supreme
    Court explained, Owen initiated many of the questioning sessions, was repeatedly
    advised of his rights to remain silent and to counsel, acknowledged and waived
    those rights, and expressed a desire to confess to crimes if the police could
    convince him they had enough evidence to convict him. Owen I, 560 So. 2d at
    209–10. “Consequently, there evolved a procedure whereby the police officers
    would present their evidence and attempt to persuade him that they had the
    necessary proof.” Id. at 210.
    On the first four days of questioning, Owen confessed to a number of
    burglaries, sexual batteries, and other crimes. On the fifth day, June 18, Owen
    reinitated contact with police and renewed and expanded upon his earlier
    confessions.
    B.    Owen’s June 21 Confession
    On the sixth day, June 21, 1984, police obtained from Owen, through a
    4
    court order, an inked footprint standard to compare to the footprint found at the
    Slattery crime scene. Later that day, police officers interviewed Owen, and Owen
    confessed to the Worden and Slattery murders.
    The June 21, 1984 questioning began at 6:29 p.m.2 Boca Raton police
    officer Kevin McCoy read Owen his Miranda rights, and Owen said he understood
    them. Officer McCoy and another officer revealed that Owen had left a fingerprint
    at the Worden murder scene. Owen conceded that the fingerprint was “[r]eally
    strong evidence.” Owen then confessed to murdering Worden, and answered
    questions about details of his crime.
    Later, at 7:39 p.m., police initiated a new interview with Owen, this time
    about the Slattery murder. Most of the questioning was by Delray Beach police
    officer Mark Woods and his supervisor, Lt. Rick Lincoln. Owen was read his
    Miranda rights again, and Owen again indicated he understood them.
    The entire Slattery interview, including breaks, lasted about three hours.
    Officer Woods discussed the Slattery evidence with Owen. Owen suggested the
    evidence was not as strong as the Worden evidence, stating, “they found a
    fingerprint in that other one.” Owen was asked whether the fingerprint was “what
    2
    We have a precise chronology of the interview on June 21, 1984 because it, like the other
    Owen police interviews, was video-recorded.
    5
    it took to get you to tell them about” the Worden murder, and Owen responded,
    “Once I see it on paper, you know. . . . [T]hey found the fingerprint . . . and . . . so,
    like they say, the game is over, man.”
    Lt. Lincoln told Owen it was “really not difficult to put [the Slattery and
    Worden] cases together” because “the similarities are just astounding.” Early in
    the interview, Lt. Lincoln showed Owen pictures of the bloody footprint left at the
    Slattery crime scene and Owen’s inked footprint impression. Officer Woods told
    Owen it was “the same footprint,” and Owen agreed that it “looks identical to me.”
    Throughout the three-hour Slattery interview, Owen freely answered many
    questions. Even early on in the interview, Owen never disavowed his guilt in
    Slattery’s murder—as Lt. Lincoln later pointed out, Owen “won’t lie” when
    “confronted with the truth”—and Owen even inculpated himself by admitting his
    footprint “looks identical” to the one made in Slattery’s blood. The Miranda-
    confession issues here involve only two time points in the interview, and we quote
    the relevant interrogation for full context.
    After 43 minutes of the Slattery interview, the officers inquired about
    whether Owen had looked for a particular house. Owen replied: “I’d rather not
    talk about it,” as follows:
    OFFICER LINCOLN: Satisfy yourself right now. There’s a few things
    6
    . . . that I have to know, Duane. A couple pieces of the puzzle don’t fit.
    How did it come down? Were you looking at that particular house or
    just going through the neighborhood?
    THE DEFENDANT: I’d rather not talk about it.
    OFFICER WOODS: Why?
    OFFICER LINCOLN: Why? You don’t have to tell me about the details
    if you don’t want to if you don’t feel comfortable about that. Was it just
    a random thing? Or did you have this house picked out? That’s what
    I’m most curious about[.] Things happen, Duane. We can’t change them
    once they’re done.
    THE DEFENDANT: No.
    (Emphasis added.)
    The officers asked Owen about other details of the Slattery murder and
    reminded him of the evidence against him. Lt. Lincoln said “the time has come,”
    and Owen responded, “Yeah.” Owen admitted, “There ain’t no way out,” but he
    was “just trying to think about the situation, you know.”
    In response to further questioning, Owen told the officers that he did not
    know the Helms and had never been to their house before the night Slattery was
    killed. Then, at seventy minutes into the Slattery interview, the police officers
    asked a series of questions about the bicycle Owen rode to the Helms’ house, and
    Owen answered questions. At one point, however, in response to a specific
    question about where Owen put the bicycle, Owen said, “I don’t want to talk about
    it,” as follows:
    OFFICER LINCOLN: . . . What did you do with it? You must have put
    7
    it someplace[.] Where? Over in that field across from the house? A lot
    of woods over in there. That’s where I’d probably put it. Is that where
    you put it?
    OFFICER WOODS: He don’t have the bicycle, Duane. He’s just trying
    to fill in the blanks, you know.
    THE DEFENDANT: Yeah.
    OFFICER LINCOLN: Duane knows.
    OFFICER WOODS: Tell him.
    OFFICER LINCOLN: There’s only two places it could have—could
    have been, Duane, after you moved it. Either behind the house or in
    front of the house. Which was it?
    OFFICER WOODS: Well?
    THE DEFENDANT: How do you know I even had a bike? You don’t
    even know that.
    OFFICER LINCOLN: You tell me you didn’t have a bicycle. See, you
    won’t lie, Duane. I know you won’t lie when you are confronted with
    the truth. Now, are you going to tell me you didn’t have a bicycle? I
    know that much about you now. You play by the rules. Those rules are
    important. We all need rules.
    Now, did you have a bicycle? Of course, you did. Now, where
    did you put it?
    THE DEFENDANT: I don’t want to talk about it.
    (Emphasis added.)3
    Later in the interview, Owen asked the officers if they could arrange for
    Owen’s brother to speak to him in person. Lt. Lincoln said he was not in a
    position to make any promises. Lt. Lincoln told Owen that “Boca’s got you
    nailed” for the Worden murder, and Owen could not “be punished twice for the
    same thing.” Owen replied, “I know, but two counts, man, that’s pretty heavy, you
    3
    The two questions to which Owen responded by saying he did not want to talk about it
    occurred 27 minutes apart.
    8
    know.” The conversation continued, and Owen admitted the police had “got [him]
    good”:
    Q.     How long were you outside the house, Duane? Hours? Minutes?
    A.     You guys got me good, man.
    Q.     Yeah.
    A.     Yeah. I knew it too.
    Q.     Did you?
    A.     Yep. As soon as they asked me for footprints. . . . I knew they
    wouldn’t be asking for it unless they had something.
    Q.     Yeah.
    A.     Yeah, unless they had something, man.
    Q.     How long were you outside?
    A.     What the hell, like you said, two— It doesn’t make no difference
    once you got one.
    After pausing to think for a moment “about specifics and stuff,” Owen
    began to share the details of the Slattery crime. The details Owen provided, some
    of which only the killer would know, included the following: (1) he put socks on
    his hands before he entered through the bedroom window; (2) he stole a pair of
    leather ladies gloves inside the house and moved his socks back to his feet; (3) he
    closed the door to the children’s room; (4) Slattery was watching television and,
    after pausing to check on the children, picked up the phone to make a call when
    Owen confronted her; (5) Owen grabbed the phone from Slattery and put it back
    on its cradle; (6) Owen then began “sticking her” with the knife; (7) Slattery tried
    to push Owen away and he came up from behind and stabbed her in the back; (8)
    9
    Slattery fell to the floor on her back and stopped fighting; (9) Owen checked on
    the children again and shut their door, locked the front door and turned off most of
    the lights; (10) Owen dragged Slattery by her feet into the bedroom; (11) Owen
    took off her shorts and pushed up her shirt and bra, then raped her; and (12) Owen
    showered before leaving.
    C.    Motion to Suppress
    In the Slattery case, a grand jury indicted Owen on charges of first-degree
    murder, sexual battery, and burglary of a dwelling with intent to commit sexual
    battery inside. Owen’s counsel moved to suppress Owen’s confession. After
    holding an evidentiary hearing, the state trial court denied Owen’s motion to
    suppress.
    D.    First Trial and Reversal on Direct Appeal
    In 1985, Owen was tried in the Slattery case. The State introduced Owen’s
    confession, plus corroborating evidence, including the bloody footprint. The jury
    found Owen guilty on all charges.
    After the penalty phase, the jury recommended the death penalty on the
    first-degree murder conviction by an 11-to-1 vote. The state trial court imposed
    the death penalty for the Slattery murder conviction and life imprisonment for the
    10
    sexual battery and armed burglary convictions.4
    Owen appealed. The Florida Supreme Court reversed Owen’s convictions
    and remanded for a new trial. Owen I, 560 So. 2d at 212. The Florida Supreme
    Court concluded that, although Owen’s confession to the Slattery murder was
    voluntary for Fifth Amendment purposes, it was “obtained in violation of the
    procedural rules of Miranda” because the questioning continued after Owen made
    the statements, “I’d rather not talk about it,” and “I don’t want to talk about it.” Id.
    at 210–11 (citing Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
     (1966)).
    The Florida Supreme Court determined it could not affirm the denial of
    Owen’s motion to suppress in light of “the well-established rule that a suspect’s
    equivocal assertion of a Miranda right terminates any further questioning except
    that which is designed to clarify the suspect’s wishes.” Id. at 211 (emphasis
    added). The Florida Supreme Court found that Owen’s “responses were, at the
    least, an equivocal invocation of the Miranda right to terminate questioning, which
    could only be clarified.” Id.
    E.     Supreme Court’s Intervening Decision in Davis v. United States
    In 1994, more than four years after the Florida Supreme Court’s remand but
    4
    Later, in 1986, Owen was tried and convicted of Worden’s murder and was sentenced to
    death. On direct appeal, the Florida Supreme Court affirmed Owen’s Worden convictions and
    sentence. Owen v. State, 
    596 So. 2d 985
     (Fla. 1992).
    11
    before Owen was re-tried, the United States Supreme Court decided Davis v.
    United States, 
    512 U.S. 452
    , 
    114 S. Ct. 2350
     (1994). In Davis, the Supreme Court
    held that if a suspect during police questioning makes an “ambiguous” or
    “equivocal” reference to an attorney, such “that a reasonable officer in light of the
    circumstances would have understood only that the suspect might be invoking the
    right to counsel” under Miranda, the police need not cease questioning the suspect.
    Davis, 
    512 U.S. at 459
    , 
    114 S. Ct. at 2355
    . Instead, to assert his right to counsel, a
    “suspect must unambiguously request counsel”—that is, he “must articulate his
    desire to have counsel present sufficiently clearly that a reasonable police officer
    in the circumstances would understand the statement to be a request for an
    attorney.” 
    Id.
     (emphasis added). Further, although “it will often be good police
    practice” for police officers confronted with an ambiguous or equivocal statement
    to ask clarifying questions, the Supreme Court declined to require clarifying
    questioning, reiterating that “[u]nless the suspect actually requests an attorney,
    questioning may continue.” 
    Id.
     at 461–62, 
    114 S. Ct. at
    2356–57.
    F.    State’s Motion to Reconsider
    After Davis, the State moved the state trial court to “revisit the Florida
    Supreme Court’s ruling” as to the suppression of Owen’s confession. The state
    trial court denied the motion, and the State petitioned the Fourth District Court of
    12
    Appeal for certiorari. The Fourth District Court of Appeal denied certiorari but
    certified the issue of the admissibility of Owen’s confession to the Florida
    Supreme Court. State v. Owen, 
    654 So. 2d 200
    , 202 (Fla. 4th DCA 1995) (“Owen
    II”).
    On certification, the Florida Supreme Court in Owen III concluded, “Davis
    now makes it clear that, contrary to our belief at the time, federal law did not
    require us to rule Owen’s confession inadmissible.” Owen III, 
    696 So. 2d at 718
    .
    Although Davis involved an ambiguous request for an attorney, the Florida
    Supreme Court determined that Davis’s reasoning applies to an equivocal or
    ambiguous “assertion of any right under Miranda,” including the right to remain
    silent. 
    Id.
     at 717–18. The Florida Supreme Court concluded that “police in
    Florida need not ask clarifying questions if a defendant who has received proper
    Miranda warnings makes only an equivocal or ambiguous request to terminate an
    interrogation.” 
    Id. at 719
    . Florida’s constitution and the U.S. Constitution were
    coterminous as to the application of Miranda on this issue. 
    Id.
     at 719–20.
    In Owen III, the Florida Supreme Court then turned to “the question of how
    to treat Owen’s confession” in light of its prior holding in Owen I that the
    confession was inadmissible. 
    Id. at 720
    . The Florida Supreme Court recognized
    the law of the case doctrine, but noted that “[a]n intervening decision by a higher
    13
    court”—such as the Supreme Court’s Davis decision—is an exceptional situation
    in which a court could depart from the law of the case and reconsider a prior legal
    decision made in a case. 
    Id.
     The Florida Supreme Court concluded that “reliance
    upon our prior decision in Owen’s direct appeal would result in manifest injustice
    to the people of this state because it would perpetuate a rule which we have now
    determined to be an undue restriction of legitimate law enforcement activity.” 
    Id.
    The Florida Supreme Court did not reinstate Owen’s convictions, however,
    but instead remanded for new proceedings in the trial court under the Davis
    rationale:
    Because Owen’s responses were equivocal, the State would have this
    Court reinstate Owen’s convictions on the ground that a retrial is
    unnecessary in light of our decision. We are unwilling to go that far. Our
    prior decision which reversed Owen’s convictions and remanded for a
    new trial is a final decision that is no longer subject to rehearing. With
    respect to this issue, Owen stands in the same position as any other
    defendant who has been charged with murder but who has not yet been
    tried. Just as it would be in the case of any other defendant, the
    admissibility of Owen’s confession in his new trial will be subject to the
    Davis rationale that we adopt in this opinion. However, Owen’s prior
    convictions cannot be retroactively reinstated.
    
    Id.
     (footnote omitted).5 In short, having reversed Owen’s earlier convictions and
    5
    In stating that Owen’s responses were “equivocal,” the Florida Supreme Court explicitly
    “reject[ed] Owen’s argument that because we termed his comments to be ‘at least equivocal’ in
    our earlier opinion we should now construe his comments as unequivocal.” Owen III, 
    696 So. 2d at
    720 n.8.
    14
    remanded for a new trial, the Florida Supreme Court determined that the
    admission of Owen’s confession at that new trial would be subject to the Davis
    rationale. 
    Id.
    G.    Renewed Motion to Suppress
    After remand to the state trial court, Owen renewed his motion to suppress
    his confession. The state trial court held a hearing, at which police officers
    Lincoln, McCoy, and Woods again testified. Owen also testified.
    The police officers each testified they did not threaten Owen or make him
    any promises and that they repeatedly informed Owen of his right to remain silent.
    Owen agreed he was made no promises and was told he could cut off questioning
    at any time. Owen conceded that he never invoked his right to an attorney before
    confessing because an attorney might advise him not to speak to police and he
    wanted to speak to police.
    After hearing the evidence, the state trial court denied Owen’s motion to
    suppress. The state trial court first found that, based on the totality of the
    circumstances, Owen’s confession was voluntary.
    The state trial court then examined whether Owen “unequivocally” invoked
    his right to remain silent on June 21, 1984. The state trial court (1) interpreted the
    Florida Supreme Court’s Owen III decision to mean that Owen’s statements were
    15
    equivocal and thus under the Davis rationale his confession was admissible, but
    (2) also independently found that, based upon its own review of the videotaped
    questioning, the equivocal nature of Owen’s supposed invocation of his right to
    remain silent was “clearly depicted.”
    H.    Jury Selection
    In Owen’s retrial, jury selection ran from January 4 to January 20, 1999.
    The process included a written questionnaire to the venire members, plus oral voir
    dire by the court and counsel.6 Among other things, the venire members were
    questioned about their views on the death penalty and an insanity defense. Upon
    challenge by counsel for the parties, the state trial court excused many panel
    members for cause. The State and the defense used their peremptory challenges to
    remove other potential jurors.
    At the conclusion of voir dire, the attorneys for both sides expressly
    accepted the twelve jurors selected. Owen conferred with his counsel and told the
    state trial court that he agreed with the jurors chosen to comprise the panel.
    I.    Guilt Phase
    The guilt phase of Owen’s retrial began January 20, 1999. The State played
    6
    Owen was represented by attorneys Carey Haughwout and Donnie Murrell, and the State
    by Wayne Chalu and Christopher Moody.
    16
    Owen’s videotaped confession to police. The State also presented corroborating
    evidence, including the testimony of a DNA expert that (1) the semen found in
    Slattery’s body contained DNA markers linking it to Owen, who is Caucasian, and
    (2) only 1 out of 690 million Caucasian males would have those same DNA
    markers.
    The defense conceded that Owen committed the murder but argued he was
    insane at the time of the crime.7 The defense called two mental health experts,
    clinical psychologist Dr. Faye Sultan and psychologist/psychiatrist Dr. Fredrick
    Berlin, both of whom testified Owen was insane when he murdered Slattery.8
    During the State’s cross-examination of Dr. Berlin (which took up nearly 50
    transcript pages), the State briefly asked Dr. Berlin about his personal views on the
    death penalty. Dr. Berlin acknowledged he was opposed to the death penalty but
    would not let that alter his objectivity about the case:
    Q. You understand that the death penalty is a possible punishment in
    this case should the defendant be found guilty of first degree murder?
    A. Yes, sir.
    Q. And may I ask you, Doctor, what your view is on that issue of the
    7
    As defense counsel Haughwout stated in her opening statement, “This case is about why
    it happened. We know what happened. Duane told [the police] what happened. Duane told
    them everything the prosecutor just told you.”
    8
    Dr. Berlin was unavailable to testify during the trial, so (1) he testified in court before the
    jury panel was selected, (2) his testimony was videotaped, and (3) selected portions of the
    videotape were played for the jury.
    17
    death penalty?
    A. I am personally opposed to the death penalty.
    Q. So you don’t want to see Mr. Owen executed; isn’t that correct?
    A. That’s correct. But I certainly wouldn’t let that, to the best [of] my
    ability, alter my objectivity in this case. So I want to make that clear.
    Owen’s counsel objected to the admission of this cross-examination,
    arguing that Dr. Berlin’s personal objection to the death penalty was (1) irrelevant
    to the question of Owen’s guilt and sanity and (2) prejudicial because it was not
    shared by the jurors, who had been death-qualified. The state trial court overruled
    the objection.
    On January 29, 1999, the jury found Owen guilty of first-degree murder,
    attempted armed sexual battery with a deadly weapon or force likely to cause
    serious personal injury, and armed burglary of a dwelling.
    J.    Penalty Phase and Sentencing
    At the penalty phase, Owen recalled Dr. Sultan and Dr. Berlin and called
    neuropsychologist Dr. Barry Crown. On March 4, 1999, the jury recommended a
    death sentence by a 10-to-2 vote.
    On March 23, 1999, the state trial court announced Owen’s sentence. On
    that day, nearly 15 years to the day after Owen murdered Karen Slattery, Owen,
    18
    for the second time, received the death penalty for her murder.9
    K.     Second Direct Appeal
    Owen appealed to the Florida Supreme Court. See Owen v. State, 
    862 So. 2d 687
     (Fla. 2003) (“Owen IV”). Owen argued, among other things, that the state
    trial court “erred in failing to suppress Owen’s confession because Owen made an
    unequivocal invocation of his right to remain silent which was ignored by the law
    enforcement officers questioning him.” 
    Id. at 693
    . Owen did not appeal the
    admission of the State’s cross-examination of Dr. Berlin in the guilt phase about
    his personal view on the death penalty.
    The Florida Supreme Court affirmed Owen’s convictions and death
    sentence. 
    Id.
     On the Miranda claim, the Florida Supreme Court found that the
    “trial court properly rejected Owen’s motion to suppress” because the Florida
    Supreme Court itself had, “on numerous occasions, deemed Owen’s responses to
    be equivocal.”10 
    Id. at 697
    . In any event, the Florida Supreme Court also
    concluded that the state trial court’s independent finding of equivocality was
    9
    Owen received a life sentence for the armed burglary and a 15-year sentence for the
    attempted armed sexual battery.
    10
    The Florida Supreme Court pointed out that (1) in Owen III, it had “specifically stated
    that ‘Owen’s responses were equivocal’” and “rejected Owen’s argument that . . . they should be
    considered unequivocal”; and (2) “in numerous other opinions,” it had “made reference to
    Owen’s responses as exemplars of ‘equivocal utterances.’” Owen IV, 
    862 So. 2d at 697
    .
    19
    “fully supported by competent, substantial evidence” at the suppression hearing.
    
    Id.
     The Florida Supreme Court stated:
    Clearly, we have concluded that Owen’s statements were equivocal
    responses in context and under the circumstances presented. Owen did
    not, during the motion to suppress hearing below, offer any testimony
    or evidence to contradict our prior determinations. Therefore, under
    State v. Owen, 
    696 So.2d 715
     (Fla.1997), the law enforcement officers
    questioning Owen had no duty to further clarify his equivocal responses
    in the context presented or terminate the interrogation. The trial court
    properly denied Owen’s motion to suppress.
    
    Id.
     at 697–98.11
    L.     State Postconviction Proceedings
    On October 31, 2005, Owen filed a Florida Rule of Criminal Procedure
    3.851 motion for capital postconviction relief. Owen alleged, among other things,
    that he received ineffective assistance of trial counsel during jury selection
    because his counsel (1) failed to challenge for cause or use a peremptory challenge
    to remove jurors Sharon Knowles, Betty Matousek, and Betty Jean Griffin; and (2)
    failed to object to allegedly improper statements by the State and the trial court.
    The state postconviction court held an evidentiary hearing. Owen’s trial
    11
    Owen also argued that he was coerced into confessing to the Slattery murder and thus
    his confession should have been suppressed because it was involuntary. 
    Id.
     at 693–94. The
    Florida Supreme Court rejected this claim, noting that: (1) in Owen I, it had held Owen’s
    confession was voluntary; (2) the law of the case doctrine controlled; (3) Owen did not present
    any new evidence justifying reviewing the voluntariness issue; and (4) even without the law of
    the case doctrine, the record showed that the state trial court correctly found Owen’s confession
    was voluntary. 
    Id.
     at 694–96.
    20
    counsel, Carey Haughwout, testified that she did not recall any details of what
    happened, or what decisions she made, during jury selection.
    On September 21, 2006, the state postconviction court denied Owen’s 3.851
    motion. As to Owen’s jury-selection claim, the state postconviction court found
    no deficient performance by Owen’s trial counsel. The state postconviction court
    further concluded, as to jurors Matousek and Griffin, that Owen had not shown
    prejudice.
    Owen appealed the denial of his 3.851 motion. He also filed in the Florida
    Supreme Court a state habeas petition that claimed, among other things, that his
    state appellate counsel was ineffective for failing to raise on appeal the State’s
    guilt-phase impeachment of Dr. Berlin based on his personal views on the death
    penalty.
    The Florida Supreme Court affirmed the denial of 3.851 postconviction
    relief and denied Owen’s habeas petition. Owen v. State, 
    986 So. 2d 534
    , 541
    (Fla. 2008) (“Owen V”). As to the jury-selection claim, the Florida Supreme
    Court noted that “‘where a postconviction motion alleges that trial counsel was
    ineffective for failing to raise or preserve a cause challenge, the defendant must
    demonstrate that a juror was actually biased’ to be entitled to relief.” 
    Id. at 549
    (quoting Carratelli v. State, 
    961 So. 2d 312
    , 324 (Fla. 2007)). The Florida
    21
    Supreme Court concluded that Owen was “not entitled to relief because he did not
    demonstrate that an actually biased juror served on his jury.” Id. at 550.12
    The Florida Supreme Court also denied Owen’s claim of ineffective
    assistance of appellate counsel. Id. at 557. The Florida Supreme Court determined
    that the issue about the State’s cross-examination of Dr. Berlin about his death
    penalty views “would have been found to be without merit on direct appeal”
    because, even if the trial court had erred in permitting the State to ask the
    questions, the error was harmless. Id.
    M.     Federal Habeas Petition
    On August 7, 2008, Owen filed his 
    28 U.S.C. § 2254
     petition for a writ of
    habeas corpus. Owen raised numerous claims, including violation of his right to
    remain silent and ineffective assistance of trial and appellate counsel. On
    November 30, 2010, the district court issued a thorough 67-page order denying
    each claim.
    The district court granted a certificate of appealability (“COA”) on three
    12
    The Florida Supreme Court also rejected Owen’s arguments that trial counsel was
    ineffective for not objecting to certain comments as to the insanity defense and mitigating
    circumstances by the State and the state trial court during jury selection. Owen V, 
    986 So. 2d at
    550–551. The Florida Supreme Court concluded that Owen failed to show either deficient
    performance or prejudice as to the state trial court’s comments on mitigating circumstances
    because the jury was properly instructed on mitigation and the trial court’s comments on
    mitigation were not improper. 
    Id. at 551
    . The Florida Supreme Court found that Owen failed to
    show any prejudice resulting from the comments by the State. 
    Id.
    22
    claims: (1) whether the police’s continued questioning violated Owen’s right to
    remain silent and to be free from self-incrimination; (2) whether Owen’s trial
    counsel was ineffective during jury selection; and (3) whether Owen’s appellate
    counsel on direct appeal was ineffective for not arguing that the trial court
    erroneously allowed the State to cross-examine and improperly impeach Dr. Berlin
    on his personal views on the death penalty. Owen appealed to this Court.13
    II. DISCUSSION
    A.    Standard of Review
    Under § 2254(d), as amended by the Antiterrorism and Effective Death
    Penalty Act of 1996 (“AEDPA”), a federal court cannot grant a state prisoner a
    writ of habeas corpus on a claim decided on the merits in state court unless the
    state court’s decision was (1) “contrary to, or involved an unreasonable
    application of, clearly established Federal law, as determined by the Supreme
    Court of the United States,” or (2) “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); see Reed v. Sec’y, Fla. Dep’t of Corr., 
    593 F.3d 1217
    , 1239 (11th Cir.
    13
    This Court denied Owen’s motion to expand the COA.
    23
    2010).14 “We review de novo the district court’s decision about whether the state
    court acted contrary to clearly established federal law, unreasonably applied
    federal law, or made an unreasonable determination of fact.” Reed, 
    593 F.3d at 1239
     (quotation marks omitted).
    B.     Miranda and Owen’s Confession
    Owen argues, as he has done throughout, that the admission of his
    confession to murdering Karen Slattery violated Miranda v. Arizona, 
    384 U.S. 436
    , 
    86 S. Ct. 1602
     (1966). He contends that his two statements, “I’d rather not
    talk about it,” and “I don’t want to talk about it,” were unequivocal invocations of
    his right to remain silent, and therefore the police officers’ questioning should
    have stopped.
    In Owen IV, the Florida Supreme Court held that the state trial court
    properly denied Owen’s renewed motion to suppress because “Owen’s statements
    were equivocal responses in context and under the circumstances presented.”
    14
    “A state court’s decision is ‘contrary to’ federal law if the ‘state court arrives at a
    conclusion opposite to that reached by the Supreme Court on a question of law or if the state
    court decides a case differently than the Supreme Court has on a set of materially
    indistinguishable facts.’” Consalvo v. Sec’y for Dep’t of Corr., 
    664 F.3d 842
    , 844 (11th Cir.
    2011) (brackets omitted) (quoting Williams v. Taylor, 
    529 U.S. 362
    , 413, 
    120 S. Ct. 1495
    , 1523
    (2000)). A state court’s decision involves an unreasonable application of federal law “if the state
    court identifies the correct governing legal principle from the Supreme Court’s decisions but
    unreasonably applies that principle to the facts of the prisoner’s case.” 
    Id.
     (quotation marks and
    brackets omitted) (quoting Williams, 
    529 U.S. at 413
    , 
    120 S. Ct. at 1523
    ).
    24
    Owen IV, 
    862 So. 2d at 697
    . After review, we readily conclude that the Florida
    Supreme Court’s decision about Owen’s confession was not contrary to or based
    on an unreasonable application of clearly established Supreme Court precedent,
    nor was it based on an unreasonable determination of the facts.
    In Miranda, the Supreme Court held that when a person questioned in police
    custody indicates that “he wishes to remain silent, the interrogation must cease.”
    Miranda, 
    384 U.S. at
    473–74, 
    86 S. Ct. at 1627
    . However, a defendant who
    wishes to invoke his right to remain silent must do so “unambiguously” and
    “unequivocal[ly].” See Davis, 
    512 U.S. at
    458–62, 
    114 S. Ct. at
    2355–57 (stating
    that a “suspect must unambiguously request counsel” and “[i]f the suspect’s
    statement is not an unambiguous or unequivocal request for counsel, the officers
    have no obligation to stop questioning him”); Berghuis v. Thompkins, — U.S. —,
    
    130 S. Ct. 2250
    , 2259–60 (noting Davis held that an ambiguous or equivocal
    invocation of Miranda’s right to counsel did not require police to stop questioning
    or to ask only clarifying questions, and determining that “there is no principled
    reason to adopt different standards for determining when an accused has invoked
    the Miranda right to remain silent and the Miranda right to counsel”).
    25
    Under the facts here, and Davis alone,15 it was not unreasonable for the
    Florida Supreme Court to conclude that Owen’s confession was admissible
    because he did not unequivocally invoke his right to remain silent. It is
    undisputed that Owen was informed of his right to remain silent and understood
    that right and that he could invoke it at any time. Owen initiated many of the
    questioning sessions and admitted at the second suppression hearing that he
    wanted to speak to police. Owen repeatedly expressed a desire to confess to
    crimes of which he believed the police had enough evidence to convict him
    anyway.
    As to the two statements—“I’d rather not talk about it” and “I don’t want to
    talk about it”—both were made in response to questions about specific, discrete
    details of the crime, not general questions about the crime itself. Both times,
    Owen used the pronoun “it,” which could have referred to the specific detail being
    asked about. The first time, Lt. Lincoln asked Owen, “Were you looking at that
    15
    We say Davis alone because the 1994 Davis decision predated the Florida Supreme
    Court’s 2003 Owen IV decision. In contrast, Thompkins—which marked the U.S. Supreme
    Court’s first enunciation of the principle that invocations of the right to remain silent (as opposed
    to the right to counsel) must be unambiguous—came years after the Florida Supreme Court’s
    2003 decision in Owen IV, and thus does not qualify as clearly established federal law for
    purposes of AEDPA. See Yarborough v. Alvarado, 
    541 U.S. 652
    , 660–61, 
    124 S. Ct. 2140
    , 2147
    (2004) (stating that “clearly established Federal law” under AEDPA means “the holdings, as
    opposed to the dicta, of [the Supreme] Court’s decisions as of the time of the relevant state-court
    decision” (quotation marks omitted)). Notably, Thompkins, like Owen IV, relied on the 1994
    Davis decision, too.
    26
    particular house or just going through the neighborhood?” and Owen responded,
    “I’d rather not talk about it.” Lincoln in turn responded, “Why? You don’t have
    to tell me about the details if you don’t want to [or] if you don’t feel comfortable
    about that.”16 Owen continued speaking with the officers. Twenty-seven minutes
    passed, during which Owen continued his dialogue with the officers. Then Lt.
    Lincoln said Owen had a bicycle on the night of the Slattery murder and asked
    Owen where he put the bicycle. Owen responded, “I don’t want to talk about it.”
    Above we quoted the full context of the questioning, which demonstrates the “it”
    refers to the bicycle. Again, Owen continued speaking with the officers.
    Based on the evidence presented in state court, it was not unreasonable for
    the Florida Supreme Court to conclude that Owen’s two statements about not
    wanting to “talk about it”—which were isolated statements, made nearly 30
    minutes apart, in response to questions about very specific details, in the midst of
    a give-and-take discussion of the evidence against Owen—did not constitute an
    16
    Lincoln’s responses to this statement and to Owen’s later statement about not wanting
    to talk seem to indicate Lincoln had the subjective belief that Owen was—or at least may have
    been—only reticent to discuss certain details of the murder, not the murder in general. We
    recognize that Lincoln’s subjective understanding of Owen’s intention does not decide the issue,
    because the test for whether an invocation of a Miranda right is unequivocal is an objective one.
    But Lincoln’s expression of the belief that Owen was referring only to certain details, and
    Owen’s failure to correct him, is something that the Florida Supreme Court properly could have
    considered in determining whether under the totality of the circumstances Owen’s statements
    were equivocal.
    27
    unequivocal invocation of Owen’s right to remain silent. An unequivocal and
    unambiguous invocation of the right to remain silent is one articulated
    “sufficiently clearly that a reasonable police officer in the circumstances would
    understand the statement to be a request” to exercise his right to remain silent and
    terminate the interrogation, not that it might be a request to remain silent. Davis,
    
    512 U.S. at 459
    , 
    114 S. Ct. at 2355
     (emphasis added); see also United States v.
    Mikell, 
    102 F.3d 470
    , 477 (11th Cir. 1996) (“Pursuant to Davis, we hold that a
    suspect’s refusal to answer certain questions is not tantamount to the invocation,
    either equivocal or unequivocal, of the constitutional right to remain silent and
    that questioning may continue until the suspect articulates in some manner that he
    wishes the questioning to cease.”). Here, the state trial court could reasonably
    conclude that an officer in Lt. Lincoln and Officer Woods’s place reasonably
    could believe that Owen’s statements did not mean he wanted to invoke his right
    to remain silent. The Florida Supreme Court’s decision, affirming the denial of
    Owen’s renewed motion to suppress, did not contravene or unreasonably apply
    clearly established United States Supreme Court precedent, and it was not based
    on an unreasonable determination of the facts in light of the evidence presented in
    28
    state court.17 Thus, Owen is not entitled to habeas relief on his Miranda claim.18
    Nor is Owen entitled to relief on his claim that his confession should have
    been suppressed because it was involuntary. The Florida Supreme Court twice
    held that Owen’s confession to murdering Slattery was given voluntarily. See
    Owen I, 560 So. 2d at 210 (“The tapes show that the confession was entirely
    voluntary under the fifth amendment and that no improper coercion was
    employed.”); Owen IV, 
    862 So. 2d at 696
     (“Owen was made fully aware of his
    constitutional rights, and knowingly and voluntarily confessed to the Slattery
    homicide on June 21, 1984. Clearly, based upon the evidence presented during the
    17
    Owen argues he never received a full and fair hearing on whether he unequivocally
    invoked his right to remain silent because: (1) at the first suppression hearing, the equivocal
    versus unequivocal nature of Owen’s invocation was not in issue; and (2) at the second
    suppression hearing, the state trial court believed it was bound by the Florida Supreme Court’s
    earlier determination that Owen’s statements were equivocal.
    We reject this argument. In Owen IV, the Florida Supreme Court found that, although the
    state trial court at the second suppression hearing could simply have relied upon the law of the
    case, the trial court in fact went further and permitted Owen to introduce new evidence and make
    new arguments, then made an “independent determination,” which was supported by the
    evidence at the hearing, that Owen’s statements were equivocal. Owen IV, 
    862 So. 2d at
    697–98. This conclusion by the Florida Supreme Court was based on evidence and was not an
    unreasonable determination of the facts.
    18
    Further, even if Owen’s statements were not susceptible to two equally plausible
    different interpretations—and thus were not ambiguous or equivocal in fact—at the least we
    conclude that some fairminded jurists could believe the Florida Supreme Court was correct in
    finding them to be so. That is all AEDPA requires to prohibit us from granting federal habeas
    relief. See Harrington v. Richter, 562 U.S. —, 
    131 S. Ct. 770
    , 786 (2011) (observing that
    AEDPA bars federal habeas relief if “fairminded jurists could disagree” on the state court’s
    merits determination). At the very minimum, Owen’s statements were arguably ambiguous or
    equivocal.
    29
    motion to suppress hearing, and the entire record of this case, Owen’s confession
    was unquestionably voluntary. . . .”). The record shows that Owen wanted to
    speak with police, that he was repeatedly told that the officers could make no
    promises, and that he chose to confess because of the strength of the State’s
    evidence and the fact he had already admitted to murdering Worden and “[i]t
    doesn’t make no difference once you got one [murder conviction].” The Florida
    Supreme Court’s decision—that Owen’s confession was voluntary—was not
    contrary to clearly established Supreme Court precedent, an unreasonable
    application of Supreme Court precedent, or based on an unreasonable
    determination of the facts.
    C.    Ineffective Assistance of Trial Counsel in Jury Selection
    1.     Strickland Test
    Claims of ineffective assistance of counsel during jury selection are
    evaluated under the same standard as other ineffective assistance claims. Harvey
    v. Warden, Union Corr. Inst., 
    629 F.3d 1228
    , 1243 (11th Cir.), cert. denied, 
    132 S. Ct. 577
     (2011). The petitioner must show both (1) deficient performance by his
    trial counsel, and (2) prejudice resulting from the deficient performance.
    Strickland v. Washington, 
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    , 2064 (1984).
    To establish deficient performance, Owen “must show that his counsel’s
    30
    conduct fell below an objective standard of reasonableness in light of prevailing
    professional norms at the time the representation took place.” Rose v. McNeil,
    
    634 F.3d 1224
    , 1241 (11th Cir.) (quotation marks omitted), cert. denied, 
    132 S. Ct. 190
     (2011). The performance prong “entails a deferential review of counsel’s
    conduct,” for “courts must indulge a strong presumption that counsel’s conduct
    falls within the wide range of reasonable professional assistance.” 
    Id.
     “To
    overcome Strickland’s presumption of reasonableness, [Owen] must show that no
    competent counsel would have taken the action that his counsel did take.” 
    Id.
    (quotation marks omitted). In other words, Owen must show that his counsel
    “made errors so serious that counsel was not functioning as the ‘counsel’
    guaranteed [Owen] by the Sixth Amendment.” Strickland, 
    466 U.S. at 687
    , 
    104 S. Ct. at 2064
    .
    To establish prejudice, Owen must show 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
    , 
    104 S. Ct. at 2068
    . “A
    reasonable probability is a probability sufficient to undermine confidence in the
    outcome.” 
    Id.
     “The likelihood of a different result must be substantial, not just
    conceivable.” Harrington v. Richter, 562 U.S. —, 
    131 S. Ct. 770
    , 792 (2011).
    2.       State Court Denial
    31
    Owen claims his trial counsel were ineffective for not using a cause or
    peremptory challenge to remove jurors Knowles, Matousek, and Griffin.
    Specifically, Owen argues his counsel should have struck those jurors because: (1)
    two years before Owen’s retrial, Knowles was the victim of a home invasion
    armed robbery in which her daughter was raped; (2) Matousek believed that under
    some circumstances, the death penalty should be applied in rape cases; (3)
    Matousek indicated on her questionnaire that whether the death penalty should be
    applied automatically “depends on the circumstances”; and (4) Griffin said she
    thought the death penalty should be imposed automatically when the defendant
    killed more than one person and that, in such cases, she would “[p]robably” vote
    for the death penalty.
    The 3.851 court concluded that Owen had not shown either deficient
    performance or prejudice. The Florida Supreme Court affirmed. Owen V, 
    986 So. 2d at
    549–50.
    Specifically, the Florida Supreme Court found that the 3.851 court “did not
    err in denying this claim” because Owen failed to show that any of the three jurors
    were “actually biased.” 
    Id.
     The Florida Supreme Court observed that “[a] juror is
    competent if he or she can lay aside any bias or prejudice and render his verdict
    solely upon the evidence presented and the instructions on the law given to him by
    32
    the court.” 
    Id. at 549
     (quotation marks omitted). “Therefore, actual bias means
    bias-in-fact that would prevent service as an impartial juror.” 
    Id.
     “Under the
    actual bias standard, the defendant must demonstrate that the juror in question was
    not impartial—i.e., that the juror was biased against the defendant, and the
    evidence of bias must be plain on the face of the record.” 
    Id.
     (quoting Carratelli v.
    State, 
    961 So. 2d 312
    , 324 (Fla. 2007)).19
    The Florida Supreme Court further concluded that Owen’s argument that his
    attorneys should have struck Knowles from the jury because her daughter was
    raped in a home invasion armed robbery was “without merit” because
    “Knowles’[s] responses during voir dire indicated that she would be able to lay
    aside any bias or prejudice and render her verdict solely upon the evidence
    19
    As background, we note that to prevail on a motion to challenge a juror during the trial
    itself, Owen’s trial attorneys would have had to demonstrate actual bias. See Busby v. State, 
    894 So. 2d 88
    , 95 (Fla. 2004) (noting that standard for granting cause challenge under Florida law is
    whether there is reasonable doubt “as to whether the juror possesses an impartial state of mind,”
    which turns on “whether the juror can lay aside any bias or prejudice and render a verdict solely
    on the evidence presented and the instructions on the law given by the court”); 
    id. at 100
    (observing that “actual bias [is] the standard applicable to cause challenges”).
    However, to prevail on direct appeal on a claim that the trial court erroneously denied a
    cause challenge, Florida law requires that the defendant: (1) challenge the biased juror for cause;
    (2) if the challenge is denied, then use a peremptory strike on the actually biased juror; then (3)
    use all his other peremptory strikes; and (4) “show that an objectionable juror has served on the
    jury.” 
    Id. at 92
    , 96–97. An “objectionable juror” is one “who actually sat on the jury and whom
    the defendant either challenged for cause or attempted to challenge peremptorily or otherwise
    objected to after his peremptory challenges had been exhausted.” 
    Id. at 97
     (quoting Trotter v.
    State, 
    576 So. 2d 691
    , 693 (Fla. 1991)). The defendant need not show the “objectionable juror”
    was actually biased.

    presented and the instructions on the law given to her by the court.” 
    Id. at 550
    (quotation marks and brackets omitted). The Florida Supreme Court found that,
    “[b]ased upon the totality of Knowles’[s] responses in her voir dire, Owen has not
    shown [Knowles] to be actually biased.” 
    Id.
    The Florida Supreme Court also concluded that Owen’s claims about jurors
    Matousek and Griffin lacked merit and that Owen had not shown any actual bias
    as to Matousek and Griffin. 
    Id.
     Specifically, “[t]he record demonstrates that
    despite her personal viewpoint, juror Matousek stated a willingness and ability to
    lay aside her possible bias and follow the trial court’s instructions. Juror Matousek
    never equivocated as to whether she could follow the law, and accordingly, Owen
    has not shown her to be actually biased.” 
    Id.
     Similarly, “[w]hile Griffin answered
    that she ‘[p]robably’ would vote for the death penalty in the circumstance of
    multiple victims and gave confusing answers regarding how she would consider
    mitigating evidence, she ultimately stated that she would consider mental health
    testimony and that such testimony could influence her toward a life sentence.”20
    
    Id.
    20
    The Florida Supreme Court further concluded that trial counsel also “did not act
    ‘outside the broad range of reasonably competent performance under prevailing professional
    standards’ by not objecting to” the judge’s statement to Griffin that the trial would not involve
    more than one alleged victim.

    3.      Owen’s Arguments
    Owen argues that the Florida Supreme Court’s denial of his jury-selection
    ineffective assistance claim was contrary to Strickland because Florida’s actual-
    bias test is more onerous than Strickland’s prejudice prong, which requires a
    reasonable probability of a different result, not a plain showing of actual bias.21
    Initially, we note that it is unclear whether the Florida Supreme Court in
    Owen V was addressing the deficient performance prong or only the prejudice
    prong of Owen’s ineffective assistance claim. In Owen V, the Florida Supreme
    Court never expressly stated whether its analysis related to performance,
    prejudice, or both. On one hand, Owen V cited Carratelli, which addressed only
    the prejudice prong.
    On the other hand, Owen V expressly found that the 3.851 court (which had
    expressly determined Owen’s trial counsel’s performance was not deficient) “did
    not err” in denying Owen’s jury-selection ineffective assistance claim. Owen V,
    21
    Although the Florida Supreme Court did not cite Strickland, that does not strip the
    Florida Supreme Court’s Owen V decision of the deference due it under AEDPA. See Early v.
    Packer, 
    537 U.S. 3
    , 8, 
    123 S. Ct. 362
    , 365 (2002) (stating that, under § 2254(d), a state court
    decision “does not require citation of our cases—indeed, it does not even require awareness of
    our cases, so long as neither the reasoning nor the result of the state-court decision contradicts
    them”); Blankenship v. Hall, 
    542 F.3d 1253
    , 1271 n.4 (11th Cir. 2008) (finding the fact “[t]hat
    the state court did not specifically mention Strickland is of no moment,” for the “state court’s
    failure to cite the relevant Supreme Court precedents does not mean that AEDPA deference does
    not apply”).
    35
    
    986 So. 2d at 549
    .22 Further, the Florida Supreme Court’s analysis in Owen V
    speaks in terms of counsel’s conduct, explicitly rejecting Owen’s arguments that
    his trial counsel “should have removed” Knowles, Matousek, and Griffin. See 
    id. at 550
     (“Owen argues that trial counsel should have removed juror Knowles . . . .
    This argument is without merit. . . . Next, Owen argues that trial counsel should
    have removed . . . jurors Matousek and Griffin . . . . This argument is without
    merit.”). This language suggests the Florida Supreme Court was analyzing
    Owen’s trial counsel’s performance.
    Ultimately, we need not resolve this performance or prejudice question
    because Owen, in any event, has not shown the Florida Supreme Court’s decision
    on either prong was unreasonable or contrary to clearly established federal law.
    We explain why below.
    4.     Performance Prong
    As to the performance prong, Owen contends that no reasonable defense
    attorney would have permitted Knowles to sit on the jury because her daughter’s
    rape in the home invasion was so traumatic and so similar to the facts of the
    22
    The Supreme Court has suggested that even the ambiguity as to whether a state supreme
    court denied a habeas petitioner’s claim on an alternative ground is enough to deny the claim
    under AEDPA, provided the possible alternative ground is a reasonable basis upon which to deny
    the petitioner’s claim. See Parker v. Matthews, 567 U.S. —, 
    132 S. Ct. 2148
    , 2151 (2012).
    36
    Slattery murder that Knowles could never consider Owen’s insanity defense and
    mitigation case in an unbiased way. Owen, however, ignores Knowles’s many
    other voir dire responses. For example, Knowles repeatedly insisted she could put
    the incident aside in deciding Owen’s case. Defense counsel Haughwout
    questioned Knowles about the incident at length several times and candidly told
    Knowles she was “concern[ed]” about whether the incident would affect
    Knowles’s view of the evidence and her decisionmaking. Knowles never
    equivocated on whether she could judge the evidence fairly. Knowles repeatedly
    assured trial counsel that she could put aside her own experience and decide the
    case fairly, on its own merits. Moreover, the home invasion crime occurred two
    years earlier and the perpetrator was caught and sentenced to 18 years’
    imprisonment, a sentence with which Knowles “was pleased.”
    Importantly too, Knowles gave many responses in voir dire that suggested
    she might be a very favorable juror from the defense perspective. Regarding the
    death penalty, Knowles said she did not believe it should be imposed
    automatically; she would want to hear the entire case before deciding on a penalty
    recommendation; and she could weigh the evidence and recommend life, if
    appropriate, even in a horrible case. Regarding an insanity defense, Knowles
    agreed that someone could be so mentally ill that he does not know what he is
    37
    doing. Knowles “would listen” and “weigh the evidence” on insanity. Knowles
    said that the possibility a defendant judged insane could be released in the future
    while still dangerous (a possibility that other potential jurors said concerned them)
    would not weigh on her mind while she was deciding the insanity issue.
    In sum, Knowles answered all counsel’s questions in a manner indicative of
    an unbiased juror. Indeed, Knowles’s responses to the voir dire questions about
    critical issues such as the burden of proof, the non-automatic nature of the death
    penalty, the ability to be objective, and the ability to consider an insanity
    defense—exactly what Owen sought to prove—strongly suggested Knowles
    would be a capable juror. Owen had experienced defense counsel, who are
    “strongly presumed to have . . . made all significant decisions in the exercise of
    reasonable professional judgment.” Strickland, 
    466 U.S. at 690
    , 
    104 S. Ct. at 2066
    . Based on these facts, Owen’s trial counsel could have reasonably chosen
    not to strike Knowles from the jury. Thus, Owen has not shown deficient
    performance by his trial counsel in not striking Knowles and, therefore, Owen has
    not shown the Florida Supreme Court decision as to Knowles was unreasonable,
    much less contrary to clearly established federal law.
    As for Matousek and Griffin, Owen claims his trial counsel were ineffective
    for not striking them because, he contends: (1) Matousek thought death should be
    38
    imposed for rape in some circumstances; (2) both Matousek and Griffin indicated
    they were in favor of automatic imposition of the death penalty; and (3) Griffin
    said she would “probably” vote for the death penalty regardless of what she heard
    if the defendant killed more than one person. Again, on the particular facts of this
    case, Owen has not shown deficient performance under Strickland as to Matousek
    and Griffin.
    First, we consider the specific statements by Matousek and Griffin and their
    context. Matousek’s statement on imposing the death penalty for rape came when
    she was asked for her personal opinion on whether the death penalty “should be
    applied to more crimes than murder.” Matousek responded, “Not necessarily,” but
    allowed that “[u]nder some circumstances, it could be rape.” Next, defense
    counsel asked Matousek whether, given that Owen’s case “involves a charge of
    first degree murder and sexual battery or rape,” she thought that any penalty other
    than death would be appropriate. Matousek “thought it possibly could be[,]
    depending, as the judge has said, on the aggravating and/or mitigating
    circumstances.”
    On her questionnaire, which Matousek and the other jurors filled out before
    voir dire, Matousek had written “depends on the circumstances” in response to the
    questions whether the death penalty should be imposed automatically when the
    39
    defendant kills another person, or when the defendant kills more than one person.
    Asked at voir dire about the circumstances under which she thought the death
    penalty should be imposed automatically, Matousek answered, “I believe that if it
    was a premeditated murder and there were no mitigating circumstances at all, then
    it should be automatic.”23
    Griffin marked on her questionnaire, and explained at voir dire, that she felt
    the death penalty should be imposed automatically when the defendant kills more
    than one person. The State Attorney asked, “Does that mean if you felt that the
    defendant had killed four or five people, that [nothing] that you heard [] would
    convince you that anything other than the death penalty would be appropriate?”
    Griffin said no, that “it just depends.”
    Later, Griffin was asked again about automatic imposition of the death
    penalty, and Griffin said she would “[p]robably” vote for the death penalty if there
    were more than one victim killed. However, Griffin told the court she “could
    follow the law” and her opinion that in some cases a death sentence should be
    imposed automatically would not “take precedence over Florida law.” She also
    23
    We point out that Matousek’s statement about “automatic” imposition of the death
    penalty—in particular her reference to a complete lack of mitigating circumstances—could be
    reasonably construed to mean that Matousek was referring to the appropriate penalty when the
    result of a weighing process was obvious, not that she believed in a truly “automatic” imposition
    of the death penalty with no weighing to be done.
    40
    affirmatively said that she understood the death penalty was not automatic and that
    she would not have any problem engaging in the weighing process involved.
    Thus, the important context is that: (1) Matousek’s and Griffin’s comments
    were made in response to questions about their personal opinions and beliefs about
    the death penalty; and (2) both jurors said more than once that they understood
    Florida law mandated a weighing process and not automatic imposition of the
    death penalty, and that they could follow Florida law.24
    In addition, as with Knowles, both Matousek and Griffin gave responses
    that were favorable from the defense perspective, especially with regard to the
    insanity defense that Owen’s counsel had chosen. Matousek believed it was right
    to consider whether someone was insane at the time of the offense as part of
    determining his guilt. Matousek explained:
    If a person who is living in the real world does something that is wrong,
    whether it’s a terrible crime or not, then they should be punished for
    that. If the world they are living in is differ[ent] from my world and they
    don’t know what they have done is wrong, then they should be held or
    given counseling, but they shouldn’t necessarily be treated the same as
    the person who knew what they were doing.
    If Matousek, after hearing all the evidence, did not know whether the defendant
    24
    Griffin’s other statements that show a lack of bias included: (1) her denial that she
    would invariably vote for death in a case where the defendant killed four or five people because
    “it just depends”; and (2) her repeated assertion, described later, that she understood the law
    mandated a weighing process instead of automatic imposition of the death penalty, and that she
    could follow the law in that regard.
    41
    was sane or insane at the time of the offense, she would “have to say not guilty by
    reason of insanity because that is the law.” Matousek was okay with that.25
    Similarly, Griffin had experience with psychologists and psychiatrists and
    was confident they knew what they were talking about. Insanity could be used as
    a defense, Griffin believed, “because sometimes people are insane when they
    commit horrible crimes.” If Griffin had a reasonable doubt about whether the
    defendant was sane or insane at the time of the crime, Griffin would find him not
    guilty by reason of insanity. When told that was the law and asked if “that’s the
    way the law ought to be,” Griffin said yes.
    Other favorable responses concerned the death penalty or the penalty phase
    process. Matousek stated that her attitude about the death penalty was
    “somewhere in the middle.” Matousek was “not opposed in some cases” to
    imposing it, but there “certainly” were some circumstances in which life
    imprisonment was the appropriate penalty for first-degree murder. In considering
    the appropriate penalty, the defendant’s background would be more important to
    Matousek than the nature of the crime. Matousek would want to know as much as
    possible about the defendant, and would “definitely” want to know about the
    25
    In addition, Matousek thought most mental health experts were well-trained and well-
    meaning, and though they did not have “all the answers,” no one did. It “would be maligning the
    profession” to say that all such experts gave the opinions they did just because they were paid to.
    42
    defendant’s degree of mental illness.
    Griffin characterized her feelings about the death penalty as neutral. She
    would rather not be on a jury that had to decide whether a person should receive
    the death penalty, and she feared having to make that decision, though she could
    be fair in making it. Griffin wanted to know anything that could help her make the
    decision, including mental health information. Testimony that the defendant had a
    mental illness would be important in the guilt and penalty phases, and such
    testimony would “[p]robably” make Griffin think the defendant deserved a life
    sentence rather than death.
    Under the circumstances, Owen has not shown constitutionally deficient
    performance by his attorneys in not striking Matousek or Griffin. Both jurors
    insisted they could follow the law. A reasonable attorney in the position of
    Owen’s counsel could have concluded that, on balance, Matousek and Griffin
    would be favorable jurors compared to other members of the venire. In particular,
    both Matousek and Griffin showed themselves to be receptive to mental health
    evidence in general, and an insanity defense in particular, which was defense
    counsel’s chosen trial theory. Reasonable counsel could conclude, given the
    heinous nature of the Slattery murder and sexual assault, that picking jurors
    receptive to an insanity defense represented Owen’s best chance to avoid the death
    43
    penalty. Reasonable counsel also could have concluded that jurors (like Matousek
    and Griffin) who were “middle of the road” or “neutral” about the death penalty,
    and who wanted to know as much as possible about the defendant’s background in
    reaching a penalty-phase decision, would be beneficial to the defense.
    Therefore, to the extent the Florida Supreme Court affirmed the denial of
    Owen’s jury-selection ineffective assistance claim based on a finding of no
    deficient performance by trial counsel’s not moving to strike the three jurors
    during trial, we conclude that finding was not contrary to Supreme Court
    precedent, did not unreasonably apply Supreme Court precedent, and was not
    based on an unreasonable determination of the facts in light of the state court
    evidence.
    5.      Prejudice Prong
    To the extent the Florida Supreme Court’s denial of Owen’s jury-selection
    ineffective assistance claim was limited to an analysis of the Strickland prejudice
    prong, Owen still is not entitled to relief.26 Carratelli’s actual bias test is arguably
    consistent with Strickland. To “show that there is a reasonable probability that,
    26
    The facts of Strickland are obviously distinguishable from Owen V, as Strickland did
    not concern a jury-selection ineffective assistance of counsel claim. Indeed, Strickland did not
    involve a jury at all, for the petitioner, Washington, pled guilty and then waived his right to an
    advisory sentencing jury. See Strickland, 
    466 U.S. at 672
    , 
    104 S. Ct. at
    2056–57.
    44
    but for counsel’s unprofessional errors, the result of the proceeding would have
    been different,” Strickland, 
    466 U.S. at 694
    , 
    104 S. Ct. at 2068
    , Owen must show
    that at least one juror was biased; if no juror were biased, then there is no
    “reasonable probability that . . . the result of the proceeding would have been
    different.” 
    Id.
    Ultimately, we need not decide whether the Carratelli actual-bias test for
    prejudice imposes a higher burden or contradicts the governing Strickland
    prejudice standard.27 Even if the Carratelli prejudice test applied by the Florida
    Supreme Court in Owen V were contrary to Strickland, and thus our review were
    de novo, we conclude that Owen cannot prevail on his ineffective assistance claim.
    We are wholly unpersuaded that there was a reasonable probability of a
    different result in either the guilt or penalty phases had Owen’s attorneys removed
    these three jurors. All three jurors insisted—repeatedly and unequivocally—that
    they could follow the law, and all three jurors gave pro-defense responses to many
    27
    See Williams v. Taylor, 
    529 U.S. 362
    , 405, 
    120 S. Ct. 1495
    , 1519 (2000) (stating that
    state court decision is “contrary to” Supreme Court precedent if “the state court arrives at a
    conclusion opposite to that reached by [the Supreme] Court on a question of law” or “confronts
    facts that are materially indistinguishable from a relevant Supreme Court precedent and arrives at
    a result opposite to [the Supreme Court’s]”); see also 
    id.
     at 405–06, 
    120 S. Ct. at 1519
     (noting
    further that “[t]he word ‘contrary’ is commonly understood to mean ‘diametrically different,’
    ‘opposite in character or nature,’ or ‘mutually opposed,’” and giving example of a state court’s
    rejection of ineffective assistance claim on prejudice grounds because “the prisoner had not
    established by a preponderance of the evidence that the result of his criminal proceeding would
    have been different”).
    45
    questions. Moreover, there was no doubt that Owen committed the crime, which
    was almost inconceivably heinous and brutal. The presence of Knowles,
    Matousek, and Griffin on Owen’s jury does not undermine our confidence in the
    outcome. See Rose, 
    634 F.3d at
    1241–42 (noting that prejudice inquiry is
    “whether there is a reasonable probability that, but for counsel’s unprofessional
    errors, the result of the proceeding would have been different,” and a “reasonable
    probability is a probability sufficient to undermine confidence in the outcome”
    (quotation marks and citations omitted)). Owen is not entitled to relief on his jury-
    selection ineffective assistance of counsel claim.28
    D.     Ineffective Assistance of Appellate Counsel
    Owen claims his post-retrial appellate counsel was ineffective for not
    raising on direct appeal the State’s allegedly improper cross-examination, during
    the guilt phase, of Owen’s mental health expert Dr. Berlin based on that expert’s
    28
    Owen also challenges, as ineffective assistance, three other omissions by his trial
    counsel during jury selection: (1) not objecting to the state trial court’s statements to potential
    jurors that the mitigating circumstances would be “spelled out,” when the state trial court had not
    decided whether to (and later decided not to) give the jurors specific instructions about the non-
    statutory mitigating circumstances defense counsel would present; (2) not objecting to the State’s
    comment to a potential juror that an insanity defense could be raised whether or not it was valid;
    and (3) objecting and obtaining a curative instruction, but not moving to strike the entire jury
    panel, after the State asked a potential juror involved in prison ministry whether he had had
    contact with Owen in that capacity, thereby suggesting Owen was in prison. The State disputes
    whether these claims are within the scope of the COA. In any event, we conclude Owen has not
    shown that the Florida Supreme Court’s denial of these allegations of ineffective assistance was
    contrary to clearly established federal law, an unreasonable application of such federal law, or
    based on an unreasonable determination of the facts in light of the state court evidence.
    46
    personal views on the death penalty.
    Claims of ineffective appellate counsel are governed by the two-pronged
    Strickland test. Philmore v. McNeil, 
    575 F.3d 1251
    , 1264 (11th Cir. 2009). As to
    performance, we must keep in mind that “the Sixth Amendment does not require
    appellate advocates to raise every non-frivolous issue,” for “an effective attorney
    will weed out weaker arguments, even though they may have merit.” 
    Id.
     As to
    prejudice, the question “is whether there was a reasonable probability that the
    appellate court . . . would have granted the petitioner a new trial” had the issue
    been raised. Ferrell v. Hall, 
    640 F.3d 1199
    , 1236 (11th Cir. 2011) (quotation
    marks and brackets omitted).
    In denying this ineffective appellate counsel claim, the Florida Supreme
    Court found that, “even if the trial court erred in allowing the State to question Dr.
    Berlin regarding his personal beliefs on the death penalty, any error was
    harmless.” Owen V, 
    986 So. 2d at 557
    . The Florida Supreme Court reasoned that:
    (1) “the State’s questioning was not damaging to Dr. Berlin’s testimony about
    Owen’s sanity”; (2) Dr. Berlin answered the question professionally and his
    answer indicated he did not hold so strong a view on the death penalty that he was
    biased; (3) the State “did not dwell on the issue”; and (4) “three other mental
    health experts testified at the guilt phase about Owen’s sanity.” 
    Id.
     Thus, the
    47
    Florida Supreme Court concluded, “it seems unlikely that knowledge of Dr.
    Berlin’s view on the death penalty improperly influenced the jury’s deliberation
    about Owen’s defense. The issue would have been found to be without merit on
    direct appeal.” 
    Id.
    After our own review of the record and Owen’s arguments, we conclude
    that the Florida Supreme Court’s denial of this claim was based on a reasonable
    determination of the facts in light of the record, and neither contravened nor
    unreasonably applied clearly established Supreme Court precedent. Owen is not
    entitled to relief.
    III. CONCLUSION
    We affirm the district court’s denial of Owen’s § 2254 petition.
    AFFIRMED.
