    SUMMARY**
    Habeas Corpus
    The panel reversed the district court’s denial of a habeas
    corpus petition alleging that petitioner’s state-court
    conviction rested on a confession obtained in violation of
    Missouri v. Seibert, 
    542 U.S. 600
    (2004).
    The panel held that for the purpose of review under the
    Anti-Terrorism and Effective Death Penalty Act, Justice
    Kennedy’s concurrence in Siebert constitutes “clearly
    established” Supreme Court law. Under this concurrence, a
    post-Miranda-warning statement must be suppressed if
    interrogating officers deliberately use the two-step
    interrogation technique that was used in Siebert, and if
    effective curative measures are not taken to ensure that the
    suspect genuinely understood the Miranda warnings. The
    two-step technique involves interrogating in successive,
    unwarned and warned phases.
    The panel held that under the circumstances of this case¯
    where police interrogated the fifteen-year-old petitioner over
    the course of two days; where on the first day at a police
    station they conducted a two-hour unwarned interrogation;
    where on the second day at a sheriff’s station they obtained
    a confession during an unwarned interrogation following an
    unwarned polygraph test; and where they transported the
    petitioner back to the police station and obtained a

    REYES V. LEWIS                         3
    postwarning confession “clarifying” what he had stated at the
    sheriff’s station¯a Siebert analysis was clearly required.
    The panel held that because the state court did not
    conduct such an analysis, its decision was contrary to clearly
    established federal law, as determined by the Supreme Court,
    and thus was owed no deference. The panel held that the
    district court clearly erred in finding that the law enforcement
    officers had not deliberately employed the two-step
    interrogation process. In addition, the officers did not take
    effective curative measures. The panel held, alternatively, in
    agreement with the concurrence, that the state court’s
    conclusion that sufficient curative measures were taken was
    an unreasonable determination of the facts. The panel
    reversed and remanded with instructions to grant the writ
    unless the petitioner was tried within a reasonable time, not
    to exceed 180 days.
    Concurring, District Judge Singleton wrote that a Siebert
    analysis includes two parts. First, the court asks whether the
    two-step interrogation procedure was chosen intentionally in
    order to render subsequent Miranda warnings ineffective.
    Second, the court asks if the two-step process, whether or not
    intentional, rendered the subsequent warnings ineffective.
    Judge Singleton wrote that the state court followed Siebert by
    applying the second part of the test and concluding that
    sufficient curative measures were taken. Reviewing the first
    part of the test de novo, because the state court did not
    address it, Judge Singleton agreed with the majority that the
    use of the two-step procedure was a conscious effort to
    undermine Miranda. Granting deference to the state court on
    the second part of the Siebert test, Judge Singleton wrote that
    the state court’s finding was based on an unreasonable
    determination of the facts.

    OPINION
    W. FLETCHER, Circuit Judge:
    Petitioner Adrian Reyes petitions for a writ of habeas
    corpus on the ground, inter alia, that his state-court
    conviction rested on a confession obtained in violation of
    Missouri v. Seibert, 
    542 U.S. 600
    (2004). For the reasons that
    follow, we reverse the district court and remand with
    instructions to grant the writ.
    I. Factual Background
    On January 11, 2006, an armed person got out of a silver
    Toyota Camry and shot Derek Ochoa three times. The person
    may have yelled “Delhi” (the name of an Orange County
    gang). Ochoa died as a result of the shooting. He was a
    senior at La Sierra High School in Riverside County.
    Riverside Police Department officers traced the Camry to
    the home of Andres Munoz, an older cousin of petitioner
    Adrian Reyes. The car was registered to another member of
    the Munoz family, Albert. Reyes had recently moved to
    REYES V. LEWIS                        5
    Riverside County from Orange County. He was a freshman
    at La Sierra. He was not quite two months past his fifteenth
    birthday.
    The day before the shooting, Reyes had been walking
    home from school with a friend. A carload of gang members
    drove up and asked Reyes where he was from. Reyes
    answered “Delhi.” One of the gang members punched Reyes
    in the eye. They then drove away, yelling “South Side
    Riverside 51-50.”
    Two days after the shooting, Riverside Police Department
    homicide detectives James Brandt and Rick Wheeler
    questioned Reyes at his aunt’s home. Reyes had moved from
    his family’s home to his aunt’s home the day after his assault
    by the gang members. The detectives’ questions related
    primarily to the assault. During the questioning, Reyes
    acknowledged that he had known Ochoa and that he knew
    Delhi was a “group in Santa Ana.”
    Nearly a month later, on February 9, sometime between
    5:20 and 5:30 in the morning, a SWAT team of between
    fifteen and twenty officers executed a search warrant on
    Reyes’s aunt’s home. They handcuffed Reyes and searched
    the house. In Reyes’s bedroom they discovered papers with
    “Delhi” written in large block letters. After the house was
    secured, Reyes was released from handcuffs and allowed to
    eat breakfast.
    Brandt told Reyes that he was not under arrest, but that he
    wanted to ask him some questions at the station. Reyes
    acquiesced, and he was driven to the Riverside police station.
    Reyes was not accompanied to the station by any family
    member. At the station, Brandt and Wheeler together
    6                      REYES V. LEWIS
    questioned Reyes. At no point during their questioning on
    February 9 did they provide Miranda warnings.
    Reyes was held at the station for some time before he was
    questioned. Wheeler began the interview by saying, “Thanks
    for being so dang patient man I appreciate you . . . [h]anging
    out for us ’cause it’s been a long day, long day.” Wheeler
    told Reyes that he could stop the interview at any time: “I just
    wanna make sure that you understand that if we get at some
    point in the interview that you’re done talkin’ . . . and you
    don’t feel like answering any more questions or whatever, let
    me know, okay?”
    Wheeler asked briefly about the assault the day before the
    shooting. He then asked about the shooting. He said that the
    search warrants had been executed and that they had talked
    “with all these different people.” “[W]e got pictures, too, . . .
    and I’ve had more than one person say that’s the car that the
    guy was in, okay? . . . I’ve got enough information that shows
    that you were there.” (Wheeler’s statement was false. The
    only witness who had made any type of identification had not
    identified Reyes.) According to the transcript, Wheeler was
    interrupted by the “sound of sniffing.” Wheeler continued,
    “[T]here’s no denying it. . . . [T]he truth is gonna come out
    and, and I already know what it is.” Reyes denied that he was
    there. “I didn’t go out that day you could ask my Mom, you
    would ask anybody in my home I didn’t come out that day, I
    was sleeping.” When Wheeler said that the police had
    spoken to his family already, Reyes said, “Don’t you guys
    have a lie detector or something? I, I was in my house.”
    Brandt then took over the questioning. He challenged
    Reyes, saying that he had his phone records. “When your
    phone is being used basically six, seven, eight times an hour
    REYES V. LEWIS                        7
    every, you know, on an average every five minutes so you’re
    not sleeping okay?” Brandt was interrupted by the “sound of
    sniffing.” Brandt suggested a mitigating version of events:
    “There is a big difference between being in the car when this
    thing happens . . . and being the shooter and stuff. . . . So
    just tell us what happened, okay?” “We’ve done our
    homework, dude and . . . don’t screw yourself and lie to us,
    seriously, tell us what happened.”
    Wheeler and Brandt pressed Reyes on the inconsistency
    between Reyes’s statements and his phone records. Wheeler
    asked him about the papers found in his room with “Delhi
    written in big letters.” Brandt said, “We work homicide,
    alright, we gonna do our homework, definitely, I’m telling
    you, we have the car, we have the gun, we have five guns
    total. . . .” (Brandt’s statement was false. The Sheriff’s
    Department had not recovered—indeed, never did
    recover—the gun used to shoot Ochoa.)
    Wheeler and Brandt continued to press Reyes. Brandt
    said, “[T]here’s another detective was out showing witnesses
    the picture . . . ’cause we had a picture of you.” Wheeler
    immediately followed, “And we identified you as being in the
    car.” (Wheeler’s statement was false. Reyes had not been
    identified by anyone as having been in the car.) Brandt said,
    “I’m not trying to trick you and . . . I’m not making the stuff
    up that I’m telling you . . . . [S]o you know I’m not trying to
    trick you.”
    Brandt talked about Ochoa’s family and their “right to
    understand what happened.” Reyes responded, “I don’t really
    want to say nothing no more . . . trying to cooperate here.”
    (Elision in original.)    Brandt replied, “You’re not
    cooperating.” Brandt was interrupted multiple times by the
    8                      REYES V. LEWIS
    “sound of sniffing.” A moment later, Brandt said, “Tell me
    what happened.” Reyes responded, “I don’t know nothing
    man.”
    Reyes said, “Stop asking me questions.” Brandt said, “No
    I’m not gonna stop asking you questions.” Brandt was again
    interrupted by the “sound of sniffing.”
    Brandt said, “[A]re you willing to take a polygraph
    examination?” Reyes responded, “Yeah.” Brandt elaborated,
    “About everything.” Reyes responded, “I guess, man, I don’t
    know nothing man.” Reyes mentioned that he might need to
    have his parents there, but Brandt interrupted him, saying,
    “[W]e’ll certainly arrange for all that stuff just seeing that
    you’re willing to . . . do it.”
    A moment later, Reyes said, “You guys stop asking me
    . . . kinda questions.” (Elision in original.) “Stop[] asking
    this kind of stuff man.” Wheeler, who had begun the
    interview by telling Reyes that he could stop at any time, did
    not stop. He responded to Reyes, “The only rope that you got
    is me throwing it to you right now and telling you ‘you gotta
    be clean’ because you haven’t been. This thing’s gonna burn
    you down.”
    Wheeler persisted, interrupted frequently by the “sound
    of sniffing.” Reyes continued to indicate that he did not want
    to talk. “I’ve got nothing to say man.” Brandt took over the
    questioning: “Okay, so witnesses identifying you and other
    people in the car identifying you, . . . you’re good with that?
    . . . You want us to go in there with this two-hour
    conversation of you just lying about where you were when
    your phone records show it’s not the case and all that stuff,
    REYES V. LEWIS                        9
    you’re comfortable with that.” Reyes replied, “Stop asking
    me man. I don’t know nothing.”
    Brandt terminated the interview, saying, “This time when
    I walk out I’m not gonna come back and give you another
    shot, okay? We’re gonna, we’ll, we’ll go to the D.A.’s office
    and, and then later on to court with the case we have and, and
    I’m, I’m not worried about it, I’m not gonna lose.” Wheeler
    added, “Oh ya, we’re not gonna lose that case.” Brandt said,
    “Last chance.” Reyes responded, “I don’t know nothing
    man.”
    The transcript of the February 9 interview does not
    indicate start and stop times, but it is apparent from Brandt’s
    statement referring to “this two-hour conversation,” quoted
    above, that the interview took about two hours. Brandt
    testified at Reyes’s preliminary hearing that the interview
    had taken “forty minutes to an hour,” but his testimony is
    inconsistent with what he himself said during the interview
    and with the length of the transcript. The interview was
    interrupted thirty-three times by the “sound of sniffing.”
    Reyes went to his mother’s house to sleep that night. The
    next morning, Brandt and Michael Medici, another Riverside
    Police Department detective, picked up Reyes and took him
    to the San Bernardino County sheriff ’s station for a
    polygraph test. There is no written consent by an adult to the
    polygraph test. Brandt testified at the preliminary hearing
    that Reyes’s mother gave permission “on the phone,” and the
    record contains a police report stating that she had given
    permission. No family member accompanied Reyes to the
    sheriff’s station.
    10                     REYES V. LEWIS
    Robert Heard of the San Bernardino County Sheriff’s
    Department administered the polygraph test.           Before
    administering the test, Heard spoke with Reyes for a
    sustained period. He impressed on Reyes the fact that he was
    an experienced test administrator. He recounted that he had
    gone to “polygraph school” “9 years before you were born,”
    and that he was high demand as a polygraph teacher. At no
    point did Heard provide Miranda warnings.
    Reyes had difficulty filling out a form Heard gave him,
    not knowing his zip code or his height and weight. Reyes had
    even more difficulty with the written consent form. When he
    did not understand the terms “duress and coercion” and
    “immunity,” Heard explained them in simpler language.
    Reyes had particular trouble understanding what was meant
    by the sentence, “I hereby release the County of San
    Bernardino, the Sheriff’s Department and Examiner
    administering this examination from any and all claims
    resulting from, or arising out of, this examination. . . .” After
    Heard explained what “release . . . from any and all claims”
    meant, Reyes said, “Alright, so that, that means like that you
    guys won’t, won’t trick me . . . .” Heard corrected him,
    saying, “Well, no, this doesn’t say I won’t trick you.” Heard
    then added, “[Y]ou have my word I won’t trick you.” Heard
    again explained what “release” meant, and said, “That’s what
    it means.” Reyes responded, “Like you haven’t tricked me or
    something.” Heard replied, “Exactly, exactly.” Thus
    informed, Reyes signed the consent form.
    After administering the test, Heard told Reyes, “You
    failed the test. I have no doubt that you were there when
    Derek was shot.” (There is nothing in the record to indicate
    whether Reyes had in fact failed the test.) Heard pressed
    REYES V. LEWIS                        11
    Reyes to give details about what he had done. Reyes asked,
    “[L]ike what’s the truth gonna help?” Heard answered:
    [T]hey read my report and the detectives, their
    supervisor reads the report. . . . And the
    District Attorney’s gonna ask these detectives
    hey, how was Adrian? Is he one of these, you
    know tough, gang banger type guys[]? No,
    no. Adrian’s a nice young man. He
    cooperated, failed the test, and without
    hesitation he says hey, look, man, I feel bad
    about what happened. . . . Adrian, I can’t tell
    you what’s gonna happen because you know
    what? I don’t know. I don’t[] know what’s
    gonna happen because you haven’t told me
    what happened out there. . . . [Y]ou tell me
    I’m going to state prison for, I, I, said 25 to
    life or something like that. Fifteen year olds
    don’t go to state prison, Adrian.
    Reyes responded, “I know, but I’ve got a go to Juvenile
    Hall.” Heard replied, “Well, I don’t know what’s gonna
    happen because I, you haven’t told me anything yet, Adrian.”
    Heard continued to ask Reyes what happened, and Reyes
    repeated several times that he did not know. Heard asked
    from what side of the car the shooter had shot. Reyes
    responded, “Oh, not that I know, you know, so don’t ask any
    question.” Heard asked, “You wanna be alone?” Reyes
    replied, “No, it’s just, just don’t ask any questions,” and then
    said, “Can we just call the detectives?”
    12                    REYES V. LEWIS
    Brandt and Medici then came into the room and took over
    from Heard. At no point in the interview that followed did
    they provide Miranda warnings.
    Brandt asked at the outset, “[W]hat’s your biggest
    concern, going to jail?”
    Reyes: Think so.
    Brandt: At all or for a long time?
    Reyes: For a long time.
    Brandt: Okay, how long do you think you
    would go to jail for?
    Reyes: I don’t know. Like it’s a murder,
    probably like 25 years.
    Brandt: Yeah? How old are you?
    Reyes: 15.
    Brandt: How many 15 year olds do you know
    that go to jail for 25 years?
    Reyes: None.
    Brandt: Huh?
    Reyes: None.
    Brandt: Okay, so why would you be any
    different?
    REYES V. LEWIS                         13
    Reyes: I don’t know.
    Brandt then asked, “Remember yesterday I asked you . . .
    if Derek had anything in his hands or reached for his pockets,
    anything like that? You remember me asking you that?”
    Reyes replied, “No.” Brandt then told Reyes that Ochoa had
    had a gun:
    There’s a reason, a very easy explanation to
    this whole thing. . . . The deal is . . . Derek
    had a gun in his pocket. . . . Now, if he’s
    going for a gun in his pocket or you believed
    he was going for a gun in his pocket and we
    find one, that’s obviously, and it’s, there’s an
    explanation as to what happened. Maybe you
    just stopped and talked to him because you
    knew him, and then he’s going for a gun or
    something like that . . . and shit happens.
    (Third elision in original.) (Brandt’s statement was false.
    Ochoa had not had a gun.)
    Brandt went on, “If it’s just . . . a cold blooded thing, no,
    we just, went up and . . . did it and, and shot him just because,
    um, and I don’t feel bad about it . . . that looks bad.” Reyes
    said, “It wasn’t like that.” Brandt said, “Tell me, tell me why,
    how did it happen then?” Reyes hesitated. “I’m scared,
    man. . . . Make everybody go to prison and everything, like I
    want everybody to get locked up.” Brandt responded, “[I]f
    he’s going for a gun, dude, . . . that’s gotta be explained. We
    have to know that and we have to be able to tell the District
    Attorney’s office that . . . .” Reyes still hesitated. After
    encouragement from Brandt, he finally said, “Um hmm,
    hmm, well, he, you, he always had a gun.”
    14                     REYES V. LEWIS
    After more encouragement, Reyes said, “He was just
    running up to the car.” Brandt asked, “Okay, was he reaching
    for his pockets or anything like that?” Reyes replied, “Yeah.”
    Brandt said, “Okay, and what happened?” Reyes replied, “I
    don’t know.” Reyes expressed concern about his older
    cousin, Andres Munoz, and sought to exculpate him. “Well,
    if I say something like what’s going to happen with my
    cousin? Is he still gonna go to jail? . . . He had nothing to do
    with it.”
    Brandt asked, “Did you shoot him because you thought he
    was going for a gun? Yeah? Did you . . . see the gun in his
    pocket?”
    Reyes: He was reaching for it.
    Brandt: Okay . . . and then what happened?
    Reyes: He had a grip on it.
    Brandt: Okay, do you remember . . . what
    pocket it was in, what side it was in? Okay,
    do you remember seeing the grip of the gun
    though? And he was reaching for it? But
    what was he yelling at you guys?
    Reyes: I don’t know. It was just, I wasn’t
    panicked . . . ain’t gonna say nothing, just
    scared.
    Brandt: You were scared cause he was going
    for the gun? And then, and what happened?
    Reyes: I don’t know. I just shot.
    REYES V. LEWIS                        15
    Reyes’s statement that he had shot Ochoa came early in
    the interview, on the seventh page of the transcript. Brandt
    and Medici continued to question and talk to Reyes for
    another thirty-five pages. Much of the later exchange was
    friendly, even including a discussion of Christmas. Reyes
    said that his family opens presents at “twelve in the night.”
    Brandt responded, “Oh, see I can’t stay up that late,” and
    Reyes laughed. Near the end of the interview, Medici asked,
    “Does your Mom know about any of this, your Dad?” Reyes
    responded, “It’ll be cool like if you guys don’t tell my Mom,
    you know, cause . . . [l]ike it’ll break her heart and shit, you
    know, cause like she’s very religious.” Brandt told Reyes,
    “Oh, we don’t need to run over there.”
    Immediately after the February 10 interview at the San
    Bernardino sheriff’s station, Brandt drove Reyes back to the
    Riverside police station where he and Wheeler had
    interviewed him the day before. The length of the drive is not
    in the record, but it is apparent from a map of the area that it
    was no more than fifteen miles. When they arrived at the
    Riverside police station, Reyes was put in an interview room.
    Brandt and Medici together questioned Reyes. Brandt
    began the interview:
    OK. Uuh, we talked to people at the D.A.’s
    office and stuff about the case. Kinda told
    them that, you know, you came clean and
    finally told us the truth and why things
    happened and, you know that you were, you
    know, obviously scared and all that kind of
    stuff. Uuh, there’s more questions that they
    want answered, if we can. OK, just to, to
    clarify stuff. Alright, so I wanna talk to you
    16                    REYES V. LEWIS
    again, but because you’ve been sitting in that
    room and the door was locked and you’re not
    free to leave, I wanna read you your rights,
    OK? And then ask you some questions. OK?
    You have the right to remain silent. Anything
    you say can and will be used against you in a
    court of law. You have the right to talk to a
    lawyer and have him present with you while
    you’re being questioned. If you cannot afford
    to hire a lawyer, one will be appointed to
    represent you before any questioning. Do you
    understand each of these rights that I’ve
    explained to you? Yeah? OK. Can we talk
    about the stuff we talked about earlier today?
    Is that a yes?
    Reyes, who had not previously spoken, answered, “Yeah.”
    Under questioning from Brandt, Reyes repeated his
    confession. At the end of the interview, Reyes said, “Let me
    call my mom.” Medici then handcuffed Reyes before taking
    him to McDonald’s to get something to eat.
    The total elapsed time, from when Brandt picked up
    Reyes at his mother’s house on February 10 until the
    conclusion of the interview at the Riverside police station on
    the same day, was somewhere between five and six hours.
    Brandt testified at Reyes’s preliminary hearing that he picked
    up Reyes at approximately 9:00 am to drive him to the San
    Bernardino sheriff’s station. He estimated that Reyes then
    spent about three hours at that station, including both his
    polygraph test with Heard and his post-polygraph interview
    with Brandt and Medici. During the suppression hearing, the
    state represented that Reyes spent four hours at the San
    REYES V. LEWIS                        17
    Bernardino sheriff’s station. Brandt then drove Reyes to the
    Riverside police station for the second interview with Brandt
    and Medici. Brandt estimated that the second interview took
    between forty minutes and an hour. There is nothing in the
    record to indicate that Reyes had anything to eat until Medici
    took him to McDonald’s for a late lunch at the conclusion of
    the interview at the Riverside police station.
    II. Prior Judicial Proceedings
    Reyes and his cousin Andres Munoz were charged in
    California Superior Court with first-degree murder. They
    were tried before the same judge with separate juries. Reyes
    moved to suppress his confession as having been obtained in
    violation of Miranda. The judge concluded that Reyes’s
    February 10 post-polygraph confession at the San Bernardino
    sheriff’s station was voluntary but that he had been in custody
    within the meaning of Miranda when he made the statement.
    The judge therefore suppressed his unwarned post-polygraph
    statement at the sheriff’s station. However, the judge refused
    to suppress Reyes’s postwarning confession at the Riverside
    police station.
    At trial, there was inconsistent evidence about the identity
    of the shooter. Except for Reyes’s postwarning confession,
    the evidence largely pointed to Reyes’s cousin, Munoz, who
    had been the driver of the car, rather than Reyes, who had
    been a passenger.
    A friend of both Ochoa and Reyes testified that Reyes had
    been in the back seat, on the passenger side, of a silver car on
    the afternoon of the shooting. An eyewitness to the shooting
    testified that she saw the driver of a silver Camry get out of
    the car and shoot Ochoa. She made an in-court identification
    18                     REYES V. LEWIS
    of the driver as Munoz. Another eyewitness agreed with this
    account. She testified that the driver got out of the car,
    walked toward Ochoa, shot Ochoa, and “continue[d] shooting
    until he couldn’t anymore.” She testified that the back door
    on the driver’s side was opened, but that no one got out of the
    back seat. She was unable to identify the shooter, either
    when shown photographs shortly after the shooting, or in the
    courtroom.
    Another witness testified that he heard gunshots as he was
    pulling out of his father’s driveway. He pulled back into the
    driveway and got out of the car to look. He testified that he
    saw someone get out of the back seat on the passenger side
    and come around to the driver’s side. “I don’t know if he
    actually went to check on the kid [who had been shot] or . . .
    what else happened. . . . [I]t just happened so quick.” He
    estimated that the time between the shots being fired and the
    person getting out of the back passenger seat “wasn’t
    long”—“[m]aybe a couple of seconds.” Yet another witness,
    a friend of Ochoa’s, testified that he was on the front porch of
    a friend’s house when he heard shots. His view was obscured
    by cacti, so he “started walking toward the front yard.” “We
    were going towards [Ochoa], and that’s when we saw the guy
    shooting at him. But I only saw when he just went inside the
    car, like turned around inside the car and yelled out ‘Delhi.’”
    He testified that there were five people in the car and that it
    was “light brown.” He testified that he saw only one person
    get into the car, and that this person got into the back seat on
    the driver’s side.
    The jury returned a verdict finding Reyes guilty of first-
    degree murder with gang and firearm enhancements. The
    judge sentenced Reyes to fifty years to life in prison, twenty-
    five years for the murder conviction and twenty-five years for
    REYES V. LEWIS                       19
    the firearm enhancement. The court stayed sentencing on the
    two gang enhancements.
    Reyes appealed, claiming, inter alia, that the trial court
    had erred in admitting his February 10 confession at the
    Riverside police station, after he had received Miranda
    warnings. In his brief to the California Court of Appeal,
    Reyes made an argument based on Seibert. The Court of
    Appeal affirmed Reyes’s conviction, holding that his
    confession at the Riverside police station was admissible.
    In the view of the Court of Appeal, the “operative
    question” was whether Reyes’s post-polygraph statement had
    been voluntary. The Court of Appeal wrote:
    The issue on appeal is whether the trial
    court erred in allowing defendant’s
    subsequent statements made at the Riverside
    police station after defendant was advised of
    his Miranda rights. The operative question is
    thus whether defendant was subjected to
    coercion within the meaning of the Fifth and
    Fourteenth Amendments when he was
    interrogated at the sheriff’s station and, if so,
    whether his statements made thereafter at the
    Riverside police station were the tainted
    product of the earlier statements.
    ...
    20                     REYES V. LEWIS
    We thus will consider whether the trial
    court erred in finding that defendant’s
    statements were voluntary.
    (Emphasis added.)
    The Court of Appeal then spent nine pages analyzing in
    detail what had taken place during the post-polygraph
    interview at the police station, concluding that the “trial court
    had properly ruled defendant’s statements, both at the
    sheriff’s station and thereafter at the Riverside police station,
    were voluntary beyond a reasonable doubt.” In the view of
    the Court of Appeal, because Reyes’s statements at the
    sheriff’s station had been voluntary, his later statements at the
    police station were necessarily “likewise volitional.” The
    Court of Appeal dismissed Reyes’s argument under Seibert
    in a single paragraph, on the ground that his statement at the
    Riverside police station had been “volitional”:
    Since defendant’s statements made at the
    sheriff’s station were voluntary, his waiver of
    Miranda rights at the Riverside police station
    and statements made thereafter were likewise
    volitional. Unlike in Missouri v. Seibert
    (2004) 
    542 U.S. 600
    , 61[7], the circumstances
    in the instant case need not “be seen as
    challenging the comprehensibility and
    efficacy of the Miranda warnings to the point
    that a reasonable person in the suspect’s shoes
    would not have understood them to convey a
    message that [he] retained a choice about
    continuing to talk.” (Id. at p. 61[7].)
    (Second alteration in original.)
    REYES V. LEWIS                       21
    Reyes filed a state habeas petition contemporaneously
    with his direct appeal. The Court of Appeal declined to
    consolidate the petition and the appeal, summarily denying
    the petition in a one-sentence order. The California Supreme
    Court summarily denied both Reyes’s direct appeal and his
    habeas petition.
    Reyes timely filed a petition for federal habeas corpus
    under 28 U.S.C. § 2254. In his Report and Recommendation,
    the magistrate judge devoted most of his analysis to whether
    Reyes’s Riverside police station confession was coerced. He
    concluded under the deferential standard of the Anti-
    Terrorism and Effective Death Penalty Act (“AEDPA”) that
    the Court of Appeal had not been unreasonable in concluding
    that the confession was not coerced. He dismissed Reyes’s
    Seibert argument in a footnote, concluding that there was no
    evidence that the law enforcement officers deliberately
    employed the two-step method of interrogation condemned
    in that case. The district court adopted without comment or
    correction the conclusions and recommendations of the
    magistrate judge.
    Reyes timely appealed. Prior to oral argument, we asked
    the parties to provide supplemental briefs on Seibert and its
    application to the facts of this case.
    III. Standard of Review
    We review de novo the district court’s decision to deny
    Reyes’s habeas petition. Martinez-Villareal v. Lewis, 
    80 F.3d 1301
    , 1305 (9th Cir. 1996).
    Under AEDPA, we may not grant an application for a writ
    of habeas corpus for a state prisoner with respect to any claim
    22                     REYES V. LEWIS
    adjudicated on the merits in state court unless the state
    adjudication “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,” 28 U.S.C. § 2254(d)(1), or “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,” 
    id. § 2254(d)(2).
    “[C]learly established Federal
    law” includes only governing legal principles established by
    the United States Supreme Court at the time the state decision
    was rendered. Greene v. Fisher, 
    132 S. Ct. 38
    , 44 (2011).
    A state court’s decision is “contrary to” or is an
    “unreasonable application” of clearly established federal law
    if it applies a rule that contradicts governing Supreme Court
    precedent, “unreasonably extends a legal principle . . . to a
    new context where it should not apply, or unreasonably
    refuses to extend that principle to a new context where it
    should apply.” Williams v. Taylor, 
    529 U.S. 362
    , 405–07
    (2000).
    “A state-court decision will certainly be contrary to . . .
    clearly established precedent if the state court applies a rule
    that contradicts the governing law set forth in [Supreme
    Court] cases.” 
    Id. at 405;
    see also Early v. Packer, 
    537 U.S. 3
    , 8 (2002) (per curiam) (“Avoiding [a ‘contrary to’ error]
    does not require citation of [Supreme Court] cases—indeed,
    it does not even require awareness of [Supreme Court] cases,
    so long as neither the reasoning nor the result of the state-
    court decision contradicts them.”); Frantz v. Hazey, 
    533 F.3d 724
    , 734 (9th Cir. 2008) (en banc) (“[M]istakes in reasoning
    or in predicate decisions of the type in question here—use of
    the wrong legal rule or framework—do constitute error under
    the ‘contrary to’ prong of § 2254(d)(1).”). If a state court’s
    REYES V. LEWIS                         23
    decision is “contrary to clearly established Federal law, as
    determined by the Supreme Court,” § 2254(d)(1), a federal
    habeas court does not owe deference under AEDPA to that
    decision. 
    Frantz, 533 F.3d at 739
    ; cf. Panetti v. Quarterman,
    
    551 U.S. 930
    , 948 (2007) (stating this rule for “unreasonable
    application” error). If a “contrary to” error is identified, then
    “we must decide the habeas petition by considering de novo
    the constitutional issues raised.” 
    Frantz, 533 F.3d at 735
    .
    We may also grant a writ of habeas corpus in cases where
    the state-court decision “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)(2). We
    “may not second-guess a state court’s fact-finding process
    unless, after review of the state-court record, [we]
    determine[] that the state court was not merely wrong, but
    actually unreasonable.” Taylor v. Maddox, 
    366 F.3d 992
    , 999
    (9th Cir. 2004). To grant relief under this prong, “we must be
    convinced that an appellate panel, applying the normal
    standards of appellate review, could not reasonably conclude
    that the finding is supported by the record.” 
    Id. at 1000.
    The relevant state court decision for purposes of AEDPA
    review is the last reasoned state court decision. Ylst v.
    Nunnemaker, 
    501 U.S. 797
    , 804–06 (1991); Medley v.
    Runnels, 
    506 F.3d 857
    , 862 (9th Cir. 2007) (en banc). Here,
    that decision is the California Court of Appeal’s decision on
    direct review of Reyes’s conviction. See 
    Nunnemaker, 501 U.S. at 805
    –06.
    IV. Discussion
    Reyes makes two arguments. First, he argues that his
    warned Riverside police station confession on February 10
    24                    REYES V. LEWIS
    was coerced in violation of the Fifth Amendment. Second, he
    argues that this confession was admitted in violation of
    Seibert. For the reasons that follow, we agree with Reyes’s
    second argument. We therefore do not need to reach his first
    argument.
    A. “Contrary To”
    As the Supreme Court explained in Oregon v. Elstad,
    
    470 U.S. 298
    , 304 (1985), “[p]rior to Miranda, the
    admissibility of an accused’s in-custody statements was
    judged solely by whether they were ‘voluntary’ within the
    meaning of the Due Process Clause.” That is, the pre-
    Miranda exclusionary rule analysis was simply a Due Process
    Clause voluntariness inquiry. Miranda fundamentally altered
    the analysis: “The Miranda Court . . . presumed that
    interrogation in certain custodial circumstances is inherently
    coercive and held that statements made under those
    circumstances are inadmissible unless the suspect is
    specifically informed of his Miranda rights and freely decides
    to forego those rights.” New York v. Quarles, 
    467 U.S. 649
    ,
    654 (1984). The Court was concerned in Miranda that its
    “‘traditional totality-of-the-circumstances’ test posed an
    ‘unacceptably great’ risk that involuntary custodial
    confessions would escape detection.” 
    Seibert, 542 U.S. at 608
    (quoting Dickerson v. United States, 
    530 U.S. 428
    , 444
    (2000)). The Court therefore held in Miranda that finding a
    statement had been “voluntary” would no longer be
    sufficient. The Court explained, “Failure to administer
    Miranda warnings creates a presumption of compulsion.
    Consequently, unwarned statements that are otherwise
    voluntary within the meaning of the Fifth Amendment must
    nevertheless be excluded from evidence under Miranda.”
    
    Elstad, 470 U.S. at 307
    (emphasis added). Miranda and later
    REYES V. LEWIS                       25
    cases thus clearly establish that voluntariness, while relevant
    to the admissibility of a statement given during a custodial
    interrogation, is not by itself sufficient to establish the
    statement’s admissibility.
    Miranda was decided in 1966. By the time the Court
    decided Seibert in 2004, “Miranda warnings” had taken on
    near-talismanic significance, almost guaranteeing
    admissibility of a warned statement. Justice Souter wrote in
    Seibert that “giving the warnings and getting a waiver has
    generally produced a virtual ticket of admissibility;
    maintaining that a statement is involuntary even though given
    after warnings and voluntary waiver of rights requires
    unusual stamina, and litigation over voluntariness tends to
    end with the finding of a valid waiver.” 
    Seibert, 542 U.S. at 608
    –09 (Souter, J., plurality opinion). In Elstad, the Court
    had held that an unwarned voluntary confession followed by
    a voluntary warned confession did not require the exclusion
    of the second, warned confession. But in Seibert, the Court
    limited its holding in Elstad. In some circumstances, the
    Court wrote in Seibert, “the technique of interrogating in
    successive, unwarned and warned phases,” was a “new
    challenge to Miranda” that Elstad had not resolved. 
    Id. at 609.
    In Seibert, a police officer in Rolla, Missouri, conducted
    an unwarned interrogation of Seibert that was “systematic,
    exhaustive, and managed with psychological skill.” 
    Id. at 616.
    The unwarned interrogation produced a confession.
    The officer then gave Seibert a twenty-minute coffee and
    cigarette break. After the break, he read Seibert her Miranda
    warnings, and she signed a written waiver. The officer then
    resumed questioning, reminding Seibert of her prior
    prewarning statements. 
    Id. at 605.
    The officer later “testified
    26                     REYES V. LEWIS
    that he made a ‘conscious decision’ to withhold Miranda
    warnings, thus resorting to an interrogation technique he had
    been taught: question first, then give the warnings, and then
    repeat the question ‘until I get the answer that she’s already
    provided once.’” 
    Id. at 605–06.
    The Seibert plurality wrote,
    with some understatement, that the use of this two-step
    interrogation technique “[wa]s not confined to Rolla,
    Missouri.” 
    Id. at 609.
    Indeed, as the plurality noted, its use
    had been promoted and endorsed by national police training
    organizations including the Police Law Institute. 
    Id. at 609–10.
    Justice Souter observed in his plurality opinion in Seibert
    that the purpose of the two-step interrogation technique was
    “to render Miranda warnings ineffective by waiting for a
    particularly opportune time to give them, after the suspect has
    already confessed.” 
    Id. at 611.
    He concluded:
    It would have been reasonable to regard the
    two sessions as parts of a continuum, in which
    it would have been unnatural to refuse to
    repeat at the second stage what had been said
    before. These circumstances must be seen as
    challenging the comprehensibility and
    efficacy of the Miranda warnings to the point
    that a reasonable person in the suspect’s shoes
    would not have understood them to convey a
    message that she retained a choice about
    continuing to talk.
    
    Id. at 616–17.
    In a footnote appended to this passage, Justice
    Souter made clear that if a two-step interrogation technique
    violated Miranda, the voluntariness of the postwarning
    statement is irrelevant. In that circumstance, even a voluntary
    REYES V. LEWIS                      27
    statement must be suppressed. Justice Souter wrote,
    “Because we find that the warnings were inadequate, there is
    no need to assess the actual voluntariness of the statement.”
    
    Id. at 617
    n.8.
    Concurring, Justice Kennedy agreed with Justice Souter
    that, if deliberately employed, a two-part interrogation
    technique presented “different considerations” from earlier
    Miranda cases. 
    Id. at 620
    (Kennedy, J., concurring in the
    judgment). While Justice Kennedy’s fifth-vote concurrence
    narrowed Seibert’s holding to “those cases involving
    deliberate use of the two-step procedure to weaken
    Miranda’s protections,” United States v. Williams, 
    435 F.3d 1156
    , 1157–58 (9th Cir. 2006) (emphasis added), the plurality
    and Justice Kennedy agreed that even a voluntary
    postwarning confession must be excluded where law
    enforcement officials deliberately withheld Miranda
    warnings until after obtaining an in-custody confession, and
    where insufficient curative measures had been taken to ensure
    that the suspect understood the meaning and importance of
    the previously withheld warnings.
    Justice Kennedy wrote:
    The plurality concludes that whenever a
    two-stage interview occurs, admissibility of
    the postwarning statement should depend on
    “whether [the] Miranda warnings delivered
    midstream could have been effective enough
    to accomplish their object” given the specific
    facts of the case. . . . I would apply a
    narrower test applicable only in the infrequent
    case, such as we have here, in which the two-
    step interrogation technique was used in a
    28                   REYES V. LEWIS
    calculated way to undermine the Miranda
    warning.
    The admissibility of postwarning
    statements should continue to be governed by
    the principles of Elstad unless the deliberate
    two-step strategy was employed. If the
    deliberate two-step strategy has been used,
    postwarning statements that are related to the
    substance of prewarning statements must be
    excluded unless curative measures are taken
    before the postwarning statement is made.
    Curative measures should be designed to
    ensure that a reasonable person in the
    suspect’s situation would understand the
    import and effect of the Miranda warning and
    of the Miranda waiver. For example, a
    substantial break in time and circumstances
    between the prewarning statement and the
    Miranda warning may suffice in most
    circumstances, as it allows the accused to
    distinguish the two contexts and appreciate
    that the interrogation has taken a new turn.
    Alternatively, an additional warning that
    explains the likely inadmissibility of the
    prewarning custodial statement may be
    sufficient.
    
    Id. at 621–22
    (Kennedy, J., concurring in the judgment)
    (internal citations omitted).
    The Court has instructed us to take as “clearly
    established” for purposes of § 2254 the “narrowest” opinion
    in a fractured majority, as defined under Marks v. United
    REYES V. LEWIS                       29
    States, 
    430 U.S. 188
    , 193 (1977). See 
    Panetti, 551 U.S. at 949
    . In accordance with this instruction, we have held that
    Justice Kennedy’s concurrence “represents Seibert’s
    holding.” 
    Williams, 435 F.3d at 1158
    ; accord United States
    v. Capers, 
    627 F.3d 470
    , 476 (2d Cir. 2010) (collecting
    cases). While Supreme Court precedent is the only definitive
    source of “clearly established” federal law, we may consider
    circuit precedent for the limited purpose of assessing what
    constitutes “clearly established” Supreme Court law. Woods
    v. Sinclair, 
    764 F.3d 1109
    , 1121 (9th Cir. 2014).
    Justice Kennedy’s concurrence thus constitutes “clearly
    established” law for the purpose of AEDPA review. Under
    Justice Kennedy’s concurrence, a postwarning statement must
    be suppressed if interrogating officers deliberately use the
    two-step interrogation technique that was used in Seibert, and
    if effective curative measures are not taken to ensure that the
    suspect genuinely understood the Miranda warnings. In the
    words of Justice Kennedy, quoted above, “[c]urative
    measures should be designed to ensure that a reasonable
    person in the suspect’s situation would understand the import
    and effect of the Miranda warning and of the Miranda
    waiver.” 
    Seibert, 542 U.S. at 622
    (Kennedy, J., concurring in
    the judgment).
    The California Court of Appeal did not understand
    Seibert. In the view of the Court of Appeal, the “operative
    question” under Miranda was whether Reyes’s unwarned
    post-polygraph statement at the San Bernardino sheriff’s
    station had been voluntary. In the view of the Court of
    Appeal, if that statement had been voluntary, his later
    Mirandized statement at the San Bernardino police station
    was necessarily “likewise volitional.” The Court of Appeal
    spent nine pages addressing the voluntariness of Reyes’s
    30                    REYES V. LEWIS
    unwarned post-polygraph statement at the San Bernardino
    sheriff’s station. For the Court of Appeal, the voluntariness
    of that statement determined the admissibility of the
    subsequent warned statement at the Riverside police station.
    The Court of Appeal addressed Seibert in a single paragraph.
    We quoted that paragraph above, but we reproduce it
    here, in its entirety, for the convenience of the reader:
    Since defendant’s statements made at the
    sheriff’s station were voluntary, his waiver of
    Miranda rights at the Riverside police station
    and statements made thereafter were likewise
    volitional. Unlike in Missouri v. Seibert
    (2004) 
    542 U.S. 600
    , 616, the circumstances
    in the instant case need not “be seen as
    challenging the comprehensibility and
    efficacy of the Miranda warnings to the point
    that a reasonable person in the suspect’s shoes
    would not have understood them to convey a
    message that [he] retained a choice about
    continuing to talk.” (Id. at p. 616.)
    (Alteration in original.) The first sentence of the paragraph
    recites the Court of Appeal’s conclusion that Reyes’s
    postwarning statement was “volitional.” The second sentence
    states that, unlike in Seibert, Reyes “retained a choice about
    continuing to talk.” That is, in the Court of Appeal’s view,
    because Reyes “retained a choice,” his “continuing to talk”
    was voluntary.
    The clearly established rule under Seibert is that if
    officers deliberately employ the two-step technique employed
    in Seibert, and if insufficient curative measures are taken to
    REYES V. LEWIS                       31
    ensure that later Miranda warnings are genuinely understood,
    any warned statement thereby obtained must be suppressed,
    even if the statement is voluntary. Contrary to Seibert, the
    Court of Appeal did not address the question whether the
    officers deliberately employed the two-step technique. Also
    contrary to Seibert, the Court of Appeal did not address the
    adequacy, or even existence, of any “curative measures.”
    Instead, the Court of Appeal analyzed at length Reyes’s post-
    polygraph statement at the San Bernardino sheriff’s station
    and concluded that because it was voluntary his subsequent
    warned statement at the Riverside police station was also
    voluntary.
    Under the circumstances of this case—where police
    interrogated fifteen-year-old Reyes over the course of two
    days; where on the first day at the Riverside police station
    they conducted a two-hour unwarned interrogation; where on
    the second day at the San Bernardino sheriff’s station they
    obtained a confession during an unwarned interrogation
    following an unwarned polygraph test; and where they
    transported Reyes back to the Riverside police station and
    obtained a postwarning confession “clarifying” what he had
    stated at the sheriff’s station—a Seibert analysis was clearly
    required.
    Contrary to Seibert, the Court of Appeal did not conduct
    such an analysis. Instead, the Court of Appeal examined only
    whether Reyes’s statement in his post-polygraph interrogation
    was voluntary. It wrote, as a prelude to its analysis, that the
    “operative question” was voluntariness: “We thus will
    consider whether the trial court erred in finding that
    defendant’s statements were voluntary.” Upon determining
    that Reyes’s unwarned statements were voluntary, the Court
    of Appeal concluded that Reyes’s later warned statement at
    32                     REYES V. LEWIS
    the Riverside police station was necessarily “likewise
    volitional.” The Court of Appeal then affirmed the trial
    court’s decision not to suppress Reyes’s postwarning
    statement. The Court of Appeal thus addressed, and treated
    as dispositive, the question whether Reyes’s postwarning
    statement was voluntary, which is precisely the question that
    is irrelevant under Seibert.
    We therefore conclude that the Court of Appeal’s decision
    was “contrary to . . . clearly established Federal law, as
    determined by the Supreme Court,” 28 U.S.C. § 2254(d)(1).
    Because its decision was “contrary to” Seibert, we owe it no
    deference.
    On habeas review, the federal magistrate judge
    recommended denying relief, rejecting in a footnote Reyes’s
    argument under Seibert. The magistrate judge correctly
    understood the rule in Seibert but concluded without analysis
    of the evidence that the law enforcement officers in this case
    had not deliberately employed the two-step interrogation
    process. Deliberateness is a factual finding that we review
    for clear error. United States v. Narvaez-Gomez, 
    489 F.3d 970
    , 974 (9th Cir. 2007); McClure v. Thompson, 
    323 F.3d 1233
    , 1240 (9th Cir. 2003) (applying clear error review to
    findings of fact made by a district court on AEDPA review).
    Clear error review requires us to form a “definite and firm
    conviction that a mistake has been committed.” Easley v.
    Cromartie, 
    532 U.S. 234
    , 242 (2001) (internal quotation
    marks omitted). A more searching review is appropriate
    where the trial court’s decision was based on documents, as
    it was here, rather than credibility evaluations. See 
    id. at 243
    (“[T]he key evidence consisted primarily of documents and
    expert testimony. Credibility determinations played a minor
    role. Accordingly, we find that an extensive review of the
    REYES V. LEWIS                         33
    District Court’s findings, for clear error, is warranted.”); Bose

    466 U.S. 485
    ,
    500–01 (1984) (“The same ‘clearly erroneous’ standard
    applies to findings based on documentary evidence as to
    those based entirely on oral testimony, but the presumption
    has lesser force in the former situation than in the latter.”
    (internal citation omitted)).
    We conclude that the magistrate judge, and the district
    court in entering judgment based on the recommendation of
    the magistrate judge, clearly erred. We wrote in Williams
    that evidence of deliberateness in a Seibert inquiry can be
    either objective or subjective. “[I]n determining whether the
    interrogator deliberately withheld the Miranda warning,
    courts should consider whether objective evidence and any
    available subjective evidence, such as an officer’s testimony,
    support an inference that the two-step interrogation procedure
    was used to undermine the Miranda 
    warning.” 435 F.3d at 1158
    . The absence of direct evidence of subjective intent is
    not dispositive. 
    Capers, 627 F.3d at 479
    . As we have
    recognized, “the most plausible reason” for delaying Miranda
    warnings until after a suspect has confessed “is an illegitimate
    one, which is the interrogator’s desire to weaken the
    warning’s effectiveness,” and “‘the intent of the officer will
    rarely be as candidly admitted as it was [in Seibert].’”
    
    Williams, 435 F.3d at 1158
    –59 (quoting 
    Seibert, 542 U.S. at 617
    n.6 (Souter, J., plurality opinion)) (emphasis in original).
    In Williams, we provided a nonexhaustive list of
    probative objective evidence. Such evidence includes “the
    timing, setting and completeness of the prewarning
    interrogation, the continuity of police personnel and the
    overlapping content of the pre- and postwarning statements.”

    objective evidence under Seibert);

    should review the totality of the objective and subjective
    evidence surrounding the interrogations in order to determine

    inquiry will rely heavily, if not entirely, upon objective
    evidence.”); United States v. Nunez-Sanchez, 
    478 F.3d 663
    ,

    Based on the objective evidence in this case, we conclude
    that Brandt and his fellow officers deliberately employed the
    two-step interrogation technique condemned in Seibert, and
    that the magistrate judge and the district court clearly erred in
    concluding otherwise. Reyes first confessed in the unwarned
    interrogation conducted by Brandt and Medici at the San
    Bernardino sheriff’s station on February 10, after Heard told
    Reyes that he had failed the polygraph test. That unwarned
    interrogation, as well as the unwarned interrogation the
    previous day at the Riverside police station, were, like the
    interrogation in Seibert, “systematic, exhaustive, and
    managed with psychological skill.” 
    Seibert, 542 U.S. at 616
    .
    In the unwarned interrogation at the San Bernardino
    sheriff’s station, Brandt and Medici obtained statements from
    REYES V. LEWIS                       35
    Reyes admitting that he shot Ochoa and establishing the
    outline of the events that occurred that afternoon; information
    about how Reyes obtained the gun used in the shooting and
    what happened to it afterward; and details about the shooting.
    In the warned interrogation that followed, Reyes provided
    essentially the same information.
    The three Riverside police officers involved in the case—
    Brandt, Wheeler and Medici—were all experienced officers.
    Cf. 
    Capers, 627 F.3d at 481
    (“Inexperience, while not a
    legitimate excuse for postponing a Miranda warning,
    nevertheless may save a confession from exclusion under
    Seibert.”). All three were homicide detectives. At the time
    of the interrogations, Brandt had been a police officer in
    California for twelve years and a homicide detective for the
    last four. The tenure of Wheeler and Medici is not specified
    in the record, but we may infer from their ranks that they both
    had substantial experience.
    Brandt did not take “curative measures” to ensure that
    Reyes understood “the import and effect of the Miranda
    warning and of the Miranda waiver.” 
    Seibert, 542 U.S. at 622
    (Kennedy, J., concurring in the judgment). Indeed, he
    did quite the opposite. Brandt was the lead investigator. He
    was involved in the case from beginning to end. Brandt
    asked Reyes to accompany him to the Riverside police station
    on the morning of February 9 after the SWAT team had
    entered his aunt’s house and placed him in handcuffs. Brandt
    and Wheeler questioned Reyes at the police station for about
    two hours that day. During that interview, Brandt asked
    Reyes if he would be willing to take a polygraph
    examination. Brandt picked Reyes up at his mother’s house
    the next morning and took him to the San Bernardino
    sheriff’s station for the examination. After Heard told Reyes
    36                     REYES V. LEWIS
    that he had failed the polygraph examination, Brandt and
    Medici came into the room and took over from Heard.
    During the unwarned interview at the sheriff’s station on
    February 10, Brandt and Medici obtained a detailed
    confession from Reyes. After obtaining the confession,
    Brandt drove Reyes directly to the Riverside police station,
    where he and Wheeler had questioned him the day before.
    On arrival at the Riverside station, Brandt and Medici
    questioned Reyes again. At the beginning of this interview,
    Brandt finally provided Miranda warnings. During this
    interview, Reyes gave to Brandt and Medici the same detailed
    confessions he had just given.
    Brandt and Medici had obtained the incriminating
    information from Reyes very early in the unwarned interview
    at the sheriff’s station, on the seventh page of the transcript.
    Yet they continued questioning and talking to Reyes for
    another thirty-five pages.             They did so in a
    nonconfrontational, sympathetic way, with the result that
    Reyes was made to feel sufficiently comfortable that he
    talked about his family’s Christmas rituals and laughed when
    Brandt said he could not stay up late enough to open presents.
    At the end of the interview, Reyes even asked Brandt and
    Medici not to tell his mother what he had confessed to them:
    “It’ll be cool like if you guys don’t tell my Mom.”
    At the beginning of the follow-on interview at the
    Riverside police station, Brandt gave Reyes the Miranda
    warnings, as recounted above. But, as is evident from the
    transcript, he played down their importance. He said he
    wanted “just to clarify stuff,” suggesting by his use of the
    word “clarify” that the “stuff” had already been conveyed in
    the earlier interview, and that the only purpose of the later
    interview was clarification. Brandt then said he wanted to
    REYES V. LEWIS                       37
    “read you your rights” because “you’ve been sitting in that
    room and the door was locked and you’re not free to leave.”
    To a reasonable person not trained in the law, let alone a
    fifteen-year-old high school freshman, these stated reasons
    were hardly an effective means of conveying the fact that the
    warning he was about to give could mean the difference
    between serving life in prison and going home that night.
    After Brandt read the Miranda warnings, he said, “Do
    you understand each of these rights that I’ve explained to
    you? Yeah? OK. Can we talk about the stuff we talked
    about earlier today? Is that a yes?” While giving the
    Miranda warnings, Brandt did not pause to ask “Is that a
    yes?” after asking if Reyes understood “each of the rights”
    listed. Only after the Miranda warnings had been completed
    and after Brandt asked whether “we [can] talk about the stuff
    we talked about earlier today” did Brandt finally ask “Is that
    a yes?” and wait for a response. In contrast to the
    interrogation in Seibert, Brandt did not ask Reyes for a signed
    waiver of rights or a signed acknowledgment of having read
    and understood the Miranda warnings.
    The psychological, spatial, and temporal break between
    the unwarned and warned interrogations was not enough to
    cure the violation. Perhaps most important, Brandt had been
    a continuous presence throughout. He and Wheeler were the
    two questioners in the unwarned interrogation on February 9;
    he was the primary questioner in both the unwarned and
    warned interrogations on February 10; and he had personally
    driven Reyes on February 9 and 10, including the short trip
    between the sheriff’s station and the police station on
    February 10. Further, although the unwarned February 10
    interrogation took place at the San Bernardino sheriff’s
    station and the warned interrogation took place at the
    38                     REYES V. LEWIS
    Riverside police station, the warned interrogation was
    conducted in a familiar place where Reyes had been
    questioned by Brandt the previous day. The record does not
    tell us the driving distance and time between the sheriff’s
    station and the Riverside police station, but a map of the area
    indicates that it was no more than fifteen miles. The timeline
    for the events on February 10, described above, indicated that
    the driving time was not likely to have been more than about
    thirty minutes. This case is quite unlike Bobby v. Dixon,
    
    132 S. Ct. 26
    , 32 (2011) (per curiam), in which there was a
    four-hour gap, during which the defendant was transported
    from the police station to a separate jail and back, and during
    which the defendant spoke with his lawyer and learned
    material facts about the ongoing investigation. See also
    
    Capers, 627 F.3d at 484
    (holding that a ninety-minute break
    in time between interrogations was not curative in part
    because police personnel were consistent and “both
    [interrogations] occurred while Capers remained in handcuffs
    and in settings that clearly established the authoritative nature
    of the questioning”).
    B. “Unreasonable Determination of the Facts”
    Our concurring colleague reads the Court of Appeal’s
    decision as understanding and applying Seibert. In his view,
    the Court of Appeal’s quotation from Justice Souter’s
    plurality opinion (in the paragraph we quoted above) shows
    that it understood Seibert, and that the Court of Appeal
    viewed the question before it to be whether Brandt and his
    fellow officers took sufficient curative measures to ensure
    that the Miranda warnings given at the Riverside police
    station were effective. Thus, in the view of our concurring
    colleague, the Court of Appeal’s decision was not “contrary
    to” Seibert. But our colleague nonetheless agrees with the
    REYES V. LEWIS                        39
    result we reach in this case. In his view, even under
    AEDPA’s deferential standard, we must grant habeas relief
    because the Court of Appeal’s conclusion that sufficient
    curative measures were taken is an “unreasonable
    determination of the facts in light of the evidence presented
    in the State court proceeding.” 28 U.S.C. § 2254(d)(2). See
    Concurrence at 44–45.
    For the reason given above, we disagree with our
    concurring colleague on the question whether the Court of
    Appeal’s decision was “contrary to” Seibert. However, we
    note that, although we do not need to reach the question
    whether the Court of Appeal’s decision rests on an
    “unreasonable determination of the facts,” we entirely agree
    with him on that question. It is readily apparent, on the
    factual record of this case, that Brandt and his fellow officers
    did not take “curative measures” that would “ensure that a
    reasonable person in [Reyes’s] situation would understand the
    import and effect of the Miranda warning and of the Miranda
    
    waiver.” 542 U.S. at 622
    (Kennedy, J., concurring). Indeed,
    as described above, far from taking “curative measures,” they
    took affirmative steps to ensure that Reyes did not
    “understand the import and effect” of the Miranda warning
    he was finally given at the Riverside police station.
    Conclusion
    The California Court of Appeal applied a rule that was
    contrary to federal law as clearly established by the Supreme
    Court in Seibert when it concluded that Reyes’s postwarning
    confession was admissible solely on the ground that it was
    voluntary. We hold that police officers deliberately
    employed a two-step interrogation technique, and that they
    did not take appropriate “curative measures,” in violation of
    40                     REYES V. LEWIS
    Seibert. We therefore hold that Reyes’s postwarning
    confession should have been suppressed. Because the state
    did not argue harmless error in this court or the district court,
    that defense is waived. See United States v. Vallejo, 
    237 F.3d 1008
    , 1026 (9th Cir. 2001). Accordingly, we reverse the
    district court’s denial of Reyes’s petition for a writ of habeas
    corpus and remand with instructions to grant the writ unless
    Reyes is retried within a reasonable time, not to exceed 180
    days.
    REVERSED and REMANDED.
    SINGLETON, Senior District Judge, concurring:
    The majority has joined in a thoughtful and thorough
    judgment in this case. I concur in that judgment. The
    majority has forcefully marshaled the facts and analyzed the
    applicable law. If this case had arisen entirely within the
    federal system, e.g., under 28 U.S.C. § 2255, I would fully
    join in the opinion and have no further comments or
    suggestions.
    This case does not arise entirely within the federal system,
    however, but comes to us from state court under § 2254, and
    thus our review must be guided by the Antiterrorism and
    Effective Death Penalty Act of 1996 (AEDPA). AEDPA
    requires us to give deference to decisions of the state courts
    both as to the facts and the law, except in limited
    circumstances.
    The majority identifies Missouri v. Seibert, 
    542 U.S. 600
    (2004), as clearly established federal law at the time the
    REYES V. LEWIS                       41
    California Court of Appeal decided this case and looks to
    Justice Kennedy’s concurring opinion to provide the
    appropriate rule of decision. I agree. See United States v.
    Williams, 
    435 F.3d 1148
    , 1157–59 (9th Cir. 2006) (analyzing
    Seibert and concluding that Justice Kennedy’s opinion is the
    narrowest holding obtaining five votes). In the majority’s
    view, the California Court of Appeal recognized Seibert as
    controlling but unreasonably interpreted it, effectively
    ignoring Seibert and deciding the case under the prior law set
    out in Oregon v. Elstad, 
    470 U.S. 298
    (1985). The majority
    concludes that, since the California court failed to apply
    clearly established law, we may withhold any deference and
    exercise our independent judgment in reviewing the
    California Court of Appeal’s decision de novo.
    I disagree. My review of the record leads me to conclude
    that the California Court of Appeal’s conclusions of law are
    in conformity with Seibert and Justice Kennedy’s
    concurrence. In my view, the state court’s approach to the
    law is sound, but its finding of facts are unreasonable in
    context. I therefore, on this alternate ground, join in this
    Court’s judgment. My reasons are as follows.
    In reaching a contrary view, the majority focuses
    exclusively on one part of Justice Kennedy’s concurrence.
    Seibert addresses what we have termed a two-step
    interrogation leading to a confession. The first part of the
    interrogation is unwarned. Once the suspect confesses,
    Miranda warnings are given, and the interrogation resumes.
    Typically, the suspect confirms his confession. In practice,
    the earlier confession is suppressed, but following Elstad, the
    subsequent post-warning statement is allowed into evidence
    if it is voluntary. Seibert modified Elstad in cases such as
    this. The opinion was fragmented. Justice Souter wrote an
    42                         REYES V. LEWIS
    opinion for a plurality of four justices. Justice Kennedy
    separately concurred, arguably on a more limited basis, and
    Justice O’Connor wrote a dissent in which three other justices
    joined. The majority and I agree that Justice Kennedy’s
    opinion provides the holding of Seibert. We disagree on how
    Seibert should be applied to this case.
    In my view, Justice Kennedy adopts all of Justice Souter’s
    plurality opinion but imposes a limitation.              Rightly
    understood, Justice Kennedy’s opinion adopts a two-part test
    for determining the validity of a confession where the police
    use a two-step approach in their interrogation of a suspect.
    The first prong, which I will call the Kennedy prong, asks
    whether the two-step procedure was chosen intentionally in
    order to render subsequent Miranda warnings ineffective.
    The second prong, which I will call the Souter prong, asks if
    the two-step process, whether or not intentional, rendered the
    subsequent warnings ineffective. For Justice Kennedy, both
    prongs must be satisfied in order to create a Siebert violation
    and take the case out of Oregon v. Elstad. Since the test has
    two prongs, it is analogous to the Strickland test for
    determining ineffective assistance of counsel.1 Like that test,
    a reviewing court should be able to look to either prong first,
    and, if that prong is not satisfied, there is no need to address
    the other prong. See Pearson v. Callahan, 
    555 U.S. 223
    , 241
    (2009). Viewed in this light, the California Court of Appeal’s
    decision is within the law. That court quoted Justice Souter
    directly for the second prong of the test and concluded that
    nothing in the record of the interrogation “challenged the
    comprehensibility and efficacy of the Miranda warnings to
    the point that a reasonable person in the suspect’s shoes
    1
    Strickland v. Washington, 
    466 U.S. 668
    (1984).
    REYES V. LEWIS                              43
    would not have understood them to convey a message that
    [he] retained a choice about continuing to talk.”
    Justice Kennedy’s test requires that any two-step
    procedure must be intentionally motivated to undermine
    Miranda. Justice Souter rejects reference to the police intent
    and focuses only on whether the process itself challenged the
    comprehensibility and effectiveness of the Miranda warnings.
    Thus, if as the California Court of Appeal found, Reyes
    understood at the time of the second stage of the interview
    that he retained a choice about whether to talk, his decision to
    talk was consistent with Seibert, and there was no need for
    the Court of Appeal to address the first prong of the test and
    determine whether the police intended to nullify the Miranda
    warnings.
    The Court of Appeal did not separately address the first
    prong of the test, and so by analogy to Strickland, we may
    review that prong de novo and exercise independent
    judgment.2 See Porter v. McCollum, 
    558 U.S. 30
    , 39 (2009);
    Mann v. Ryan, 
    774 F.3d 1203
    , 1215 (9th Cir. 2014)
    (“Because the state post-conviction court did not reach the
    deficiency prong of the Strickland analysis, our review of this
    prong is not circumscribed by AEDPA.”). I agree with the
    majority that, under the facts of this case, the use of the two-
    step procedure was a conscious effort to undermine Miranda.
    2
    It is clear that the Court of Appeal did not think that the procedure
    followed undermined the effectiveness of the mid-stream Miranda
    warnings. It is not clear that the Court of Appeal considered whether the
    procedure was chosen to undermine Miranda. Even if I were to assume
    that the Court of Appeal found no intent, sub silentio, requiring deference
    I would still conclude under Williams that the procedure was chosen
    intentionally. See 
    Williams, 435 F.3d at 1160
    (discussing how to prove a
    deliberate choice of procedure).
    44                    REYES V. LEWIS
    See 
    Williams, 435 F.3d at 1158
    –60 (discussing how a court
    should determine whether an interrogation was deliberately
    used to undermine Miranda).
    The second prong of the test was addressed by the Court
    of Appeal, and we must grant deference and may only reject
    the finding if it 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)(2).
    The majority points out that the Court of Appeal did not
    explain its factual finding that the mid-stream Miranda
    warning was not undermined by the interrogation procedure
    chosen by the police. In such a case, we must look to all of
    the relevant evidence to determine if the fact finding is
    reasonably supported. See Delgado v. Lewis, 
    223 F.3d 976
    ,
    982 (9th Cir. 2000) (“Federal habeas review is not de novo
    when the state court does not supply reasoning for its
    decision, but an independent review of the record is required
    to determine whether the state court clearly erred in its
    application of controlling federal law.”). Reyes has a heavy
    burden to establish that a state court fact finding is
    unreasonable. See Burt v. Titlow, __ U.S. __, 
    134 S. Ct. 10
    ,
    15–16 (2013). I am satisfied that he has sustained that burden
    here.
    The majority has summarized all of the relevant evidence,
    and it need not be repeated here. Guided by Williams
    regarding a determination of the effectiveness of mid-stream
    Miranda warnings, see 
    Williams, 435 F.3d at 1160
    –62, I do
    not believe that there is substantial evidence that would
    support an inference that the warnings given to Reyes were
    effective at the time they were given. There is no evidence of
    the corrective measures identified by Justice Kennedy.
    REYES V. LEWIS                       45
    Turning to the factors considered relevant by the plurality:
    1) the pre-warning interrogation was complete and detailed,
    consuming many hours; 2) the two rounds of interrogation
    overlapped; 3) the two rounds of interrogation were close in
    time; 4) there was a continuity of police personnel; and, most
    importantly, 5) the interrogator’s questions treated the second
    round of interrogation as continuous with the first.
    Viewed in light of the totality of the circumstances, there
    is no evidence that would permit a finding that the two-step
    interrogation in this case did not undermine Miranda and lead
    to an involuntary confession.
