    Argued September 20, 2018—officially released March 29, 2019*
    Procedural History
    Substitute information charging the defendant, in
    three cases, with four counts of the crime of risk of
    injury to a child, two counts of the crime of sexual
    assault in the second degree and one count of the crime
    of sexual assault in the first degree, brought to the
    Superior Court in the judicial district of New Haven,
    where the court, O’Keefe, J., denied the defendant’s
    motion to suppress certain evidence; thereafter, the
    cases were tried to the jury; verdicts and judgments of
    guilty of three counts of risk of injury to a child, from
    which the defendant appealed to the Appellate Court,
    Alvord, Keller and Dennis, Js., which affirmed the judg-
    ments of the trial court, and the defendant, on the grant-
    ing of certification, appealed to this court. Reversed;
    new trial.

    Opinion
    McDONALD, J. In Davis v. United States, 
    512 U.S. 452
    , 459–60, 
    114 S. Ct. 2350
    , 
    129 L. Ed. 2d 362
    (1994),
    the United States Supreme Court determined that, after
    a defendant has been informed of his Miranda rights,1
    the police officers conducting a custodial interrogation
    have no obligation to stop and clarify an ambiguous
    invocation by the defendant of his right to have counsel
    present. Instead, they must cease interrogation only
    upon an objectively unambiguous, unequivocal invoca-
    tion of that right. See 
    id. The court
    recognized that this
    standard ‘‘might disadvantage some suspects who—
    because of fear, intimidation, lack of linguistic skills,
    or a variety of other reasons—will not clearly articulate
    their right to counsel although they actually want to
    have a lawyer present.’’ 
    Id., 460. This
    certified appeal requires us to decide whether
    the Davis standard was met in this case, and, if not,
    whether a more protective prophylactic rule is required
    under the Connecticut constitution. The defendant,
    Robert John Purcell, appeals from the Appellate Court’s
    judgment affirming his conviction of three counts of
    risk of injury to a child in violation of General Statutes
    § 53-21. We conclude that the defendant’s statements
    during interrogation did not meet Davis’ ‘‘clear and
    unequivocal’’ standard so as to require suppression of
    subsequent inculpatory statements under the federal
    constitution. We further conclude, however, that the
    Connecticut constitution does not condone a rule that
    could disadvantage the most vulnerable of our citizens.
    We hold that, to adequately safeguard the right against
    compelled self-incrimination under article first, § 8, of
    the Connecticut constitution,2 police officers are
    required to clarify an ambiguous request for counsel
    before they can continue the interrogation. Because no
    such clarification was elicited in the present case and
    the failure to do so was harmful, we conclude that the
    defendant is entitled to a new trial.
    The record reveals the following undisputed facts
    and procedural history. The complainant (victim)3 is
    the nephew of the defendant by marriage. In September,
    2013, the victim’s mother found pictures on the victim’s
    Nintendo DS game console that concerned her, includ-
    ing pictures of the clothed stomachs of the defendant
    and the victim’s father and two pictures of circumcised
    penises.4 She deleted the pictures and asked her hus-
    band to speak to the victim. The victim’s father spoke
    to him about the Catholic Church’s teachings about
    sexuality, which prompted the victim to acknowledge
    that he had had thoughts about boys but to assert that
    it was not his fault. He then stated that the defendant
    ‘‘has been having sex with me.’’ The victim’s parents
    reported the allegation to the police.
    The victim had made a similar statement concerning
    the defendant to a school social worker, who reported
    the allegation to the Department of Children and Fami-
    lies. In subsequent interviews, the victim described sev-
    eral incidents that he claimed had occurred between
    2010, when he was twelve years old, and 2013. The
    incidents were reported to have occurred in public
    restrooms and at the defendant’s home. The incidents
    were said to include inappropriate touching and sex-
    ual acts.
    In October, 2013, the defendant agreed to come to the
    Wallingford Police Department to discuss a complaint
    made against him, but he was not made aware of the
    nature of the allegations prior to arriving. Detective
    Michael Zerella and another Wallingford police officer
    conducted the interview. When it became apparent to
    the defendant that he was being accused of engaging
    in sexually inappropriate conduct with his nephew, the
    defendant explained incidents that he could think of
    that served as the basis of the complaint but maintained
    that nothing inappropriate had happened. Zerella won-
    dered aloud whether the defendant was ‘‘a sick, per-
    verted person or, or stuff, stuff accidentally happened.’’
    Not long after this comment, the defendant announced
    that things were getting ‘‘a little bit too strange,’’ and
    he terminated the interview.
    On November 26, 2013, the defendant was arrested
    pursuant to the first of three warrants and charged with
    multiple counts of both sexual assault, first and second
    degree, and risk of injury to a child.5 Later that day,
    Zerella and Wallingford Detective Sean Fairbrother con-
    ducted the custodial interrogation that gives rise to the
    issues in this certified appeal.
    The Appellate Court’s opinion accurately recounts
    the following facts relating to that interrogation. ‘‘Zer-
    ella began the interview by reading the defendant his
    Miranda rights and asking him to complete a Miranda
    waiver form. The defendant asked: ‘I can still, after,
    after, after I initial that, I can still stop answering then?’
    Zerella replied: ‘Oh, anytime you want. No problem.’
    ‘‘After the defendant completed the Miranda waiver
    form, Zerella asked the defendant whether he knew
    why he had been arrested. The defendant explained
    that he had received a letter from the Department of
    Children and Families (department) informing him that
    he was being investigated for allegations of child abuse
    with respect to the victim. When Zerella asked what he
    discussed with the department, the defendant stated
    that he had never talked to anyone from the department.
    Zerella asked why, and the defendant explained: ‘Well,
    I asked my lawyer, and he said, well, just not to, I, I
    think that’s, I think that’s all together wrong, but that’s
    what he said.’ He went on to elaborate that ‘my lawyer
    knows what’s going on, you know? But, he says don’t
    talk, I don’t talk.’ When Zerella asked him how he felt
    about that, the defendant stated: ‘Well, it’s like I said,
    I probably wouldn’t be here now if I talked to them.’
    Zerella suggested that if he had elaborated more and
    been more forthcoming during the first interview, they
    might not be here. After some discussion about whether
    and why Zerella called him a pervert during the first
    interview, Zerella stated: ‘Okay, well, we could, we
    could go on about the last interview if you want to,
    but—’ The defendant interjected: ‘—I know, I know
    . . . let’s . . . let’s go on right, what, what more do
    you want to know?’
    ‘‘After . . . [Zerella explained] that a judge and [a]
    prosecutor had found probable cause to arrest him, the
    defendant observed that it was because ‘I didn’t talk,
    that’s why.’ Zerella remarked: ‘Well, you did, you did
    talk to me. You did tell me a few things.’ The defendant
    agreed but acknowledged, ‘not enough, I know.’ . . .
    When Zerella asked the defendant to tell him some
    of the stories of his encounters with the victim, the
    defendant opined: ‘I don’t know the stories that he
    made up.’
    ‘‘Fairbrother asked the defendant whether he knew
    the crime with which he was charged, and the defendant
    replied child abuse. Fairbrother explained that he was
    charged with sexual assault and risk of injury to a child.
    The defendant asked whether that means that the alle-
    gation is that he did something sexual with the victim,
    and Fairbrother said that it did. The defendant ada-
    mantly denied having sexual relations with the victim.
    When the detectives pressed him about whether there
    were any moments that could be misconstrued as inap-
    propriate, the defendant responded: ‘Well, yes, there’s
    what, well, I, I, my lawyer said not to talk about it but,
    no . . . .’ The detectives [responded, ‘We’ll leave it up
    to you’ and ‘Well, it’s up to you’].
    ‘‘The defendant observed that Zerella had told him
    that there was a picture of him naked on the victim’s
    Nintendo DS during the first interview,6 and he asked
    repeatedly whether the picture actually existed. When
    Zerella suggested that the defendant had personal
    knowledge that the picture existed, the defendant
    insisted that he did not and that he knew about the
    picture only because Zerella told him about it during
    the first interview. Zerella maintained that ‘there’s
    other, other things, there’s other instances beside that,’
    and, after the defendant asked what, Zerella observed
    that ‘you just said, there [is] stuff but my lawyer told
    me not to talk about it.’ The defendant stated that he
    was referring to the picture. He further asked, ‘what
    else is there,’ and opined that he wanted to know ‘what
    they are pressing against me.’ Thereafter, the following
    exchange occurred:
    ‘‘ ‘[Zerella]: Alls I got to say is, tomorrow, when you
    go in to court, you’re gonna look at a judge and a
    prosecutor. . . . And they’re gonna look at all this
    stuff, all these allegations that were made against you.
    . . . That it’s a, it’s a very, very strong case against you.
    Very, very strong. They’re gonna look at it and say,
    listen, this, this man, because they don’t know you from
    Adam, but they’re just gonna see you.
    ‘‘ ‘[The Defendant]: Right. Well, they’re gonna know
    my name.
    ‘‘ ‘[Zerella]: As, as a, as a, as a mean, as a mean indi-
    vidual.
    ‘‘ ‘[The Defendant]: Right.
    ‘‘ ‘[Zerella]: In, in reality—
    ‘‘ ‘[Fairbrother]: As a predator.
    ‘‘ ‘[Zerella]: As a predator, who, who’s technically not
    cooperating and not saying, yeah, this is, this is what
    happened, this is probably why he thinks, thinks the
    way he does or—
    ‘‘ ‘[The Defendant]: —See, if my lawyer was here,
    I’d, then I’d, we could talk. That’s, you know, that’s it.
    ‘‘ ‘[Zerella]: It’s up to you. You could—
    ‘‘ ‘[The Defendant]: —I know it. I know, I know, I
    know it.
    ‘‘ ‘[Zerella]: You could . . . (a) talk to me or you
    could (b) not talk to me.
    ‘‘ ‘[The Defendant]: I know it but, I’m trying, you know
    I, I’m supposed to have my lawyer here. You know that.
    ‘‘ ‘[Zerella]: You don’t, you don’t have to, it’s, it’s—
    ‘‘ ‘[Fairbrother]: It’s up to you.
    ‘‘ ‘[Zerella]: It’s up to you, man. Some people talk to
    me without one, some people want one . . . it’s all up
    to you, man . . . I’m just affording you that opportu-
    nity, that’s all.
    ‘‘ ‘[Fairbrother]: The problem is that, at your age, you
    don’t want to go to prison.
    ‘‘ ‘[The Defendant]: [indiscernible]
    ‘‘ ‘[Fairbrother]: Okay? You don’t want to go to prison.
    If there was some inappropriate things with this child,
    something that can be explained, maybe you helped
    him go to the bathroom, maybe, you know, he makes
    some sort of crazy allegation or does some sort of
    craziness, he’s not—
    ‘‘ ‘[Zerella]: —Maybe he—
    ‘‘ ‘[Fairbrother]: He doesn’t have a hundred percent
    capacity.7 If you’re in a, now, now is the time to talk
    about it, now is [the time] to get your half out there.
    ‘‘ ‘[Zerella]: Yeah, maybe he came at you.
    ‘‘ ‘[Fairbrother]: —You know if—
    ‘‘ ‘[Zerella]: Maybe he came at you.
    ‘‘ ‘[Fairbrother]: You know, that, that’s all we’re offer-
    ing you, the opportunity to, because it’s the last time
    we’re gonna be able to talk.
    ‘‘ ‘[Zerella]: That’s all.
    ‘‘ ‘[Fairbrother]: You know, that’s all, and, and, you
    know, if—
    ‘‘ ‘[The Defendant]: —Oh, geez, I don’t know—
    ‘‘ ‘[Fairbrother]: —If you want to have an attorney—
    ‘‘ ‘[The Defendant]: —I, I don’t think it’s—
    ‘‘ ‘[Fairbrother]: —That’s fine. You can, but—
    ‘‘ ‘[The Defendant]: —that’s right, right or wrong, but,
    uh, real, really.
    ‘‘ ‘[Zerella]: Just, just affording you the opportunity,
    sir, because after, after today, you’re never gonna be
    able to, to give me or any other cop your story. You’re
    gonna let, a judge is gonna look at ya and say, some
    serious charges against you. You could go to jail for
    the rest of your life.
    ‘‘ ‘[The Defendant]: All right, now what’s, what, what,
    what, uh, all right, I’ll, I’ll, I’ll talk. Uh, what do you,
    what do you, what do you want to know? Tell, tell me,
    what do you want to know?’’ (Emphasis in original;

    , 174 Conn.
    App. 418–23.
    Thereafter, the custodial interrogation continued
    without further mention of counsel. Although the defen-
    dant did not admit to any of the acts alleged, he made
    statements that were used against him at trial.
    During trial, the defendant moved to suppress certain
    statements that he had made during the interrogation,
    claiming that they had been elicited after he invoked
    his right to have counsel present. The trial court con-
    cluded that the defendant had not invoked his right
    to counsel in an unambiguous manner, because the
    statements were susceptible to another reasonable
    interpretation when viewed in context of the statements
    preceding them. Noting that ‘‘close is not good enough,’’
    the court denied the motion.
    Following a jury trial, the defendant was convicted
    of three counts of risk of injury to a child—one count
    in violation of § 53-21 (a) (1) and two counts in violation
    of § 53-21 (a) (2).8 The defendant was acquitted of four
    other counts—one count of sexual assault in the first
    degree, two counts of sexual assault in the second
    degree, and one count of risk of injury to a child. The
    trial court rendered judgments in accordance with the
    verdicts, imposing a total effective sentence of sixteen
    years imprisonment, execution suspended after nine
    years, and ten years probation. The defendant appealed
    from the trial court’s judgments, challenging, among
    other things, the court’s denial of his motion to
    suppress.
    The Appellate Court affirmed the judgments of con-
    viction. See 
    id., 405, 440.
    The court concluded that the
    trial court properly denied the motion to suppress
    because the defendant’s rights under the fifth and four-
    teenth amendments to the federal constitution were not
    violated during the interrogation. It reasoned that the
    defendant’s references to counsel would not have been
    understood by a reasonable police officer as an expres-
    sion of a present desire to consult with counsel. 
    Id., 425–27. The
    court also rejected the defendant’s alterna-
    tive, unpreserved claim that, if his statements were an
    ambiguous invocation of his right to counsel, the self-
    incrimination and due process clauses of article first,
    § 8, of the Connecticut constitution required the officers
    to cease questioning immediately and to clarify that
    ambiguity. 
    Id., 427–40; see
    State v. Golding, 
    213 Conn. 233
    , 239–40, 
    567 A.2d 823
    (1989) (prescribing require-
    ments to obtain review and to prevail on unpreserved
    constitutional claim); see also In re Yasiel, 
    317 Conn. 773
    , 781, 
    120 A.3d 1188
    (2015) (modifying third prong
    of Golding). Nonetheless, the Appellate Court admon-
    ished law enforcement that the better practice is to
    clarify such issues at the time of interrogation rather
    than in after-the-fact arguments before the courts. State
    v. 
    Purcell, supra
    , 
    174 Conn. App. 428
    , 440. The defen-
    dant’s certified appeal to this court followed.9
    I
    We begin with the line of United States Supreme
    Court cases that provide the framework for the issues
    in this appeal. In Davis, the court acknowledged that its
    precedent had established the following foundational
    principles: ‘‘The [s]ixth [a]mendment right to counsel
    attaches only at the initiation of adversary criminal
    proceedings . . . and before proceedings are initiated
    a suspect in a criminal investigation has no constitu-
    tional right to the assistance of counsel. Nevertheless,
    we held in Miranda v. Arizona, 
    384 U.S. 436
    , 469–73
    [
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
    ] (1966), that a suspect
    subject to custodial interrogation has the right to con-
    sult with an attorney and to have counsel present during
    questioning, and that the police must explain this right
    to him before questioning begins. The right to counsel
    established in Miranda was one of a series of recom-
    mended procedural safeguards . . . [that] were not
    themselves rights protected by the [c]onstitution but
    were instead measures to [e]nsure that the right against
    compulsory self-incrimination was protected. Michi-
    gan v. Tucker, 
    417 U.S. 433
    , 443–44 [
    94 S. Ct. 2357
    , 
    41 L. Ed. 2d 182
    ] (1974); see U.S. Const., [amend. V] ([n]o
    person . . . shall be compelled in any criminal case to
    be a witness against himself).
    ‘‘The right to counsel recognized in Miranda is suffi-
    ciently important to suspects in criminal investigations,
    we have held, that it requir[es] the special protection
    of the knowing and intelligent waiver standard.
    Edwards v. Arizona, [
    451 U.S. 477
    , 483, 
    101 S. Ct. 1880
    ,
    
    68 L. Ed. 2d 378
    (1981)]. . . . If the suspect effectively
    waives his right to counsel after receiving the Miranda
    warnings, law enforcement officers are free to question
    him. . . . But if a suspect requests counsel at any time
    during the interview, he is not subject to further ques-
    tioning until a lawyer has been made available or the
    suspect himself reinitiates conversation. [Id., 484–85].
    This second layer of prophylaxis for the Miranda right
    to counsel, McNeil v. Wisconsin, 
    501 U.S. 171
    , 176 [
    111 S. Ct. 2204
    , 
    115 L. Ed. 2d 158
    ] (1991), is designed to
    prevent police from badgering a defendant into waiving
    his previously asserted Miranda rights, Michigan v.
    Harvey, 
    494 U.S. 344
    , 350 [
    110 S. Ct. 1176
    , 
    108 L. Ed. 2d
    293] (1990). To that end, we have held that a suspect
    who has invoked the right to counsel cannot be ques-
    tioned regarding any offense unless an attorney is actu-
    ally present. Minnick v. Mississippi, 
    498 U.S. 146
    [
    111 S. Ct. 486
    , 
    112 L. Ed. 2d 489
    ] (1990); Arizona v. Rober-
    son, 
    486 U.S. 675
    [
    108 S. Ct. 2093
    , 
    100 L. Ed. 2d 704
    ]
    (1988). It remains clear, however, that this prohibition
    on further questioning—like other aspects of
    Miranda—is not itself required by the [f]ifth [a]mend-
    ment’s prohibition on coerced confessions, but is
    instead justified only by reference to its prophylactic
    purpose. Connecticut v. Barrett, [
    479 U.S. 523
    , 528, 
    107 S. Ct. 828
    , 
    93 L. Ed. 2d 920
    (1987)].’’ (Citations omitted;

    Davis v. United 
    States, supra
    , 
    512 U.S. 456
    –58.
    With regard to how a defendant may invoke this right,
    in Miranda v. 
    Arizona, supra
    , 
    384 U.S. 444
    –45, the
    Supreme Court stated that if a defendant ‘‘indicates in
    any manner and at any stage of the process that he
    wishes to consult with an attorney before speaking
    there can be no questioning.’’ (Emphasis added.) In
    Edwards v. 
    Arizona, supra
    , 
    451 U.S. 484
    –85, the court
    referred to the requisite act by the defendant as ‘‘having
    expressed his desire to deal with the police only through
    counsel,’’ and as having ‘‘clearly asserted his right to
    counsel . . . .’’ The court subsequently noted that the
    invocation of the Miranda right to counsel ‘‘requires,
    at a minimum, some statement that can reasonably be
    construed to be an expression of a desire for the assis-
    tance of an attorney . . . .’’ McNeil v. 
    Wisconsin, supra
    , 
    501 U.S. 178
    .
    Applying this precedent prior to the Supreme Court’s
    1994 Davis decision, the lower courts were divided on
    how to treat an ambiguous invocation of this right.
    Three approaches emerged: one required the immediate
    cessation of interrogation; one permitted questions lim-
    ited to clarifying whether the defendant intended to
    invoke this right; and one permitted interrogation to
    continue unless a sufficiently clear invocation of the
    right was made. The second approach—stop and clar-
    ify—was adopted by the majority of the many courts
    to consider the issue. See Davis v. United 
    States, supra
    ,
    
    512 U.S. 466
    and n.1 (Souter, J., concurring); see also
    J. Ainsworth, ‘‘In a Different Register: The Pragmatics
    of Powerlessness in Police Interrogation,’’ 103 Yale L.J.
    259, 308 and n.254 (1993) (listing cases); S. Goings,

    sel in Custodial Interrogations After Davis v. United
    States,’’ 
    81 Iowa L
    . Rev. 161, 162 n.7 (1995) (same). The
    Supreme Court acknowledged this divide; see Connect-
    icut v. 
    Barrett, supra
    , 
    479 U.S. 529

    in until Davis.
    In Davis, the petitioner waived his rights to remain
    silent and to counsel in a military legal proceeding. See
    Davis v. United 
    States, supra
    , 
    512 U.S. 454
    –55. More
    than one hour into the interview, the petitioner stated,
    ‘‘ ‘Maybe I should talk to a lawyer.’ ’’ 
    Id., 455. The
    inter-
    viewing agents then explained that if the petitioner
    wanted a lawyer, they would stop questioning him,
    unless he clarified whether he was asking for a lawyer
    or was just making a comment about a lawyer. 
    Id. In response,
    the petitioner stated, ‘‘No, I’m not asking for a
    lawyer,’’ and then, ‘‘No, I don’t want a lawyer.’’ (Internal
    quotation marks omitted.) 
    Id. The interview
    recom-
    menced, but later the petitioner stated, ‘‘I think I want
    a lawyer before I say anything else.’’ (Internal quotation
    marks omitted.) 
    Id. The agents
    terminated the interview
    at that point. 
    Id. The United
    States Court of Military
    Appeals held that the petitioner’s statement, ‘‘ ‘Maybe
    I should talk to a lawyer,’ ’’ was an ambiguous invoca-
    tion of the right to counsel, and that the agents properly
    clarified the petitioner’s wishes before proceeding fur-
    ther. 
    Id., 456. On
    appeal to the United States Supreme Court, the
    petitioner contended that an ambiguous invocation is
    sufficient to invoke Edwards’ prohibition on further
    questioning, even for purposes of clarification. The
    court unanimously held that the judgment should be
    affirmed, but split five to four as to the effect of an
    ambiguous invocation under the court’s precedent. The
    majority held that, ‘‘if a suspect makes a reference to
    an attorney that is ambiguous or equivocal in that a
    reasonable officer in light of the circumstances would
    have understood only that the suspect might be invok-
    ing the right to counsel, our precedents do not require
    the cessation of questioning. . . . Rather, the suspect
    must unambiguously request counsel. . . . Although a
    suspect need not speak with the discrimination of an
    Oxford don . . . 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. If the
    statement fails to meet the requisite level of clarity,
    Edwards does not require that the officers stop ques-
    tioning the suspect.’’10 (Citations omitted; emphasis in
    original; internal quotation marks omitted.) 
    Id., 459. Applying
    this rule, the majority concluded that the
    remark, ‘‘ ‘Maybe I should talk to a lawyer’ . . . [i]s
    not a request for counsel . . . .’’ 
    Id., 462. The
    view of
    the four concurring justices, which we address in fur-
    ther detail in part III of this opinion, was that the court’s
    precedent of many decades supported the stop and
    clarify rule applied by the Court of Military Appeals.
    See 
    id., 466–67 (Souter,
    J., concurring).
    II
    The first certified issue requires us to determine
    whether the defendant’s statements during the interro-
    gation constituted an invocation of his right to counsel
    under Davis.11 The defendant contends that two state-
    ments—‘‘See, if my lawyer was here . . . then . . .
    we could talk. That’s, you know, that’s it.’’ And ‘‘I’m
    supposed to have my lawyer here. You know that.’’—
    are similar to, and have the same degree of clarity as,
    statements that other courts have deemed to meet
    Davis’ standard. We disagree.
    Since Davis, a clear, unequivocal invocation of the
    right to counsel has been found, even after a defendant
    has waived that right and cooperated to varying degrees
    with the interrogation, when a defendant has made an
    affirmative statement of present intent such as the fol-
    lowing: ‘‘ ‘Lawyer’ ’’ and ‘‘ ‘lawyer, this, this is done’ ’’;

    When statements regarding the assistance or pres-
    ence of counsel include one or more conditional or
    hedging terms, such as if, should, probably, or maybe,
    courts generally have deemed them ambiguous or equiv-

    Statements referring to counsel’s advice that the

    rights—‘‘ ‘[M]y lawyer told me, the one I talked to, not

    concern about being questioned without benefit of
    counsel, and reasonable police officer would have
    understood statements to be request for counsel to be
    present during questioning).13
    Statements that could be interpreted as an expression
    of the defendant’s reservation about whether speaking
    to the police without counsel is in his best interest also
    have been deemed not to express a clear, unequivocal
    invocation of the right to have counsel present. See,
    e.g., Sykes v. 
    State, supra
    , 
    357 S.W.3d 891
    (defendant’s
    statements—‘‘ ‘I don’t feel like that I need to be dis-
    cussing this at all,’ ‘I think it’s really plumb ignorant to
    answer any questions right now,’ ’’ and ‘‘ ‘the best thing
    I can do is, for myself, is to shut the hell up and not
    talk about this without first talking to a lawyer’ ’’—did
    not unambiguously and unequivocally indicate right to
    remain silent or right to counsel when defendant evi-
    denced awareness of his Miranda rights and continued
    to talk to officer even though he knew it was against
    his best interest); Midkiff v. Commonwealth, 
    250 Va. 262
    , 267, 
    462 S.E.2d 112
    (1995) (defendant’s ‘‘statement,
    ‘I’m scared to say anything without talking to a lawyer,’
    expresses [the defendant’s] reservation about the wis-
    dom of continuing the interrogation without consulting
    a lawyer; however, it does not clearly and unambigu-
    ously communicate a desire to invoke his right to
    counsel’’).
    With this background in mind, we turn to the state-
    ments in the present case on which the defendant relies.
    See State v. Anonymous, 
    240 Conn. 708
    , 723, 
    694 A.2d 766
    (1997) (whether defendant invoked right to counsel
    is question of law, reviewed de novo). We agree with
    the defendant that a police officer reasonably could
    interpret his statements as an invocation of his right to
    counsel. More specifically, his statements reasonably
    could be interpreted as a request to have his attorney
    present if the officers wanted him to discuss the specific
    incidents giving rise to the charges. A defendant may
    make a limited invocation of the right to counsel. See
    Connecticut v. 
    Barrett, supra
    , 
    479 U.S. 529
    (concluding
    that court could give effect to both defendant’s unam-
    biguous expression of desire to have counsel present
    before making written statement and unambiguous
    waiver of rights to remain silent and to have counsel
    present for oral statement).
    However, the statements also are reasonably amena-
    ble to a different interpretation. The defendant’s first
    statement, ‘‘if my lawyer was here,’’ is expressed in
    conditional terms, about a matter over which the defen-
    dant was given control. The defendant’s second state-
    ment refers to what he is ‘‘supposed to’’ do, which refers
    to the expectations of another, most likely his attorney.
    The existence of such expectations would be consistent
    with the defendant’s preceding remarks. In those
    remarks, the defendant explained that he had declined
    to speak with the Department of Children and Families
    about the allegations only on his attorney’s advice, even
    though the defendant himself believed that his interests
    would have been better served had he spoken to the
    department. As such, the statements on which the
    defendant relies to establish his invocation of his right
    to counsel reasonably could be interpreted as an effort
    to explain that his hesitation to speak about the allega-
    tions reflected his attorney’s advice rather than his own
    preferences. Cf. Commonwealth v. 
    Molina, supra
    , 81
    Mass. App. 867 (‘‘[t]he passage reads as though the
    defendant was using the specter of his rights as a way
    to control the interview: not asserting the rights, but
    mentioning them in order to avoid specific questions
    that he did not want to answer’’); State v. 
    Long, supra
    ,
    
    190 Wis. 2d 397
    (statement that defendant’s attorney
    told him not to talk unless attorney was present was
    not clear assertion of defendant’s desire to have counsel
    present but indication of his attorney’s advice). The
    officers’ response can be seen as consistent with that
    interpretation, insofar as they underscored that it was
    up to the defendant, not his attorney, to decide whether
    he would answer their questions.14
    The final phrase spoken by the defendant in this
    connection—‘‘You know that’’—added to the ambigu-
    ity. The officers undoubtedly knew that the defendant
    had a right to have counsel present. But they also knew,
    based on the defendant’s statements, that the defendant
    previously had been advised by counsel not to discuss
    the incidents in question. Accordingly, because the
    statements at issue cannot be considered a clear and
    unequivocal invocation of his right to counsel, we con-
    clude that the Appellate Court properly determined that
    the defendant’s statements were not the type of expres-
    sion necessary under Davis to require interrogation
    to cease.
    III
    We therefore turn to the second certified question,
    which requires us to decide whether the Appellate Court
    properly determined that article first, § 8, of the Con-
    necticut constitution does not require the police to stop
    and clarify an ambiguous or equivocal request for the
    presence of counsel. Although we appreciate the Appel-
    late Court’s thoughtful analysis of the factors that guide
    the resolution of such a question, we conclude that
    countervailing considerations, not taken into account
    in that analysis, compel a different result.
    It is well settled that the federal constitution sets the
    floor, not the ceiling, on individual rights. See State v.
    Baccala, 
    326 Conn. 232
    , 268, 
    163 A.3d 1
    , 23, cert. denied,

    138 S. Ct. 510
    , 
    199 L. Ed. 2d 408
    (2017). ‘‘[I]n
    determining the contours of the protections provided
    by our state constitution, we employ a multifactor
    approach that we first adopted in [State v. Geisler, 
    222 Conn. 672
    , 685, 
    610 A.2d 1225
    (1992)]. The factors that
    we consider are (1) the text of the relevant constitu-
    tional provisions; (2) related Connecticut precedents;
    (3) persuasive federal precedents; (4) persuasive prece-
    dents of other state courts; (5) historical insights into
    the intent of [the] constitutional [framers]; and (6) con-
    temporary understandings of applicable economic and
    sociological norms [otherwise described as public poli-
    cies].’’ (Internal quotation marks omitted.) State v. Tau-
    pier,

    , 175,

    (2018); see also
    State v. Jenkins, 
    298 Conn. 209
    , 262, 
    3 A.3d 806
    (2010)
    (recognizing that these factors ‘‘may be inextricably
    interwoven [and] [n]ot every [such] factor is relevant
    in all cases’’ ([internal quotation marks omitted]).15
    It is important to underscore that the question before
    us is not whether our state constitution provides a
    broader constitutional right than that afforded under
    the federal constitution. Cf. State v. Asherman, 
    193 Conn. 695
    , 711–15, 
    478 A.2d 227
    (1984) (declining to

    , 105 S.
    Ct. 1749, 
    84 L. Ed. 2d 814
    (1985). Instead, the issue
    we decide is whether to adopt an additional layer of
    prophylaxis to prevent a significant risk of deprivation
    of those vital constitutional rights protected under
    Miranda. See State v. Dickson, 
    322 Conn. 410
    , 426 n.11,
    
    141 A.3d 810
    (2016) (‘‘it is well established that courts

    constitutional violations, but also to craft prophylactic

    a constitutional violation’’ [emphasis omitted]), cert.

    lactic rules). As another court aptly observed, ‘‘adoption
    of a different procedural safeguard than that prescribed
    by the [United States Supreme] Court is not even, in the
    strictest sense, a matter of constitutional interpretation.
    The Miranda right to counsel is not a right found in

    nal law does not operate at the state level.’’ [Footnote
    omitted.]). Accordingly, the nature of the question
    before us will inform our consideration of the Geisler
    factors.16 Cf. State v. Santiago, 
    318 Conn. 1
    , 18 n.14,
    
    122 A.3d 1
    (2015) (‘‘In some of our decisions, we have
    utilized the multifactor Geisler analysis to flesh out the
    general nature and parameters of the state constitu-
    tional provision at issue. Having done so, we proceeded
    to resolve the appellant’s particular constitutional chal-
    lenge according to the legal test and framework relevant
    and suited to that area of the law, rather than performing
    the substantive legal analysis under the somewhat artifi-
    cial auspices of the six Geisler factors.’’).
    With regard to the first of those factors, the constitu-
    tional text, this court previously has recognized that the
    text of the due process and self-incrimination clauses
    in article first, § 8, of our state constitution; see footnote
    2 of this opinion; is not materially different from the
    corresponding clauses of the federal constitution. See
    State v. Lockhart, 
    298 Conn. 537
    , 551, 
    4 A.3d 1176

    ,

    , 715.
    This court has also recognized, however, that the due
    process concerns that operate at the intersection
    between the right to counsel and the privilege against
    self-incrimination may require greater protection than
    that afforded by the federal constitution under some
    circumstances. In State v. Stoddard, 
    206 Conn. 157
    ,
    160, 164–72, 
    537 A.2d 446
    (1988), this court declined to
    follow a recently decided United States Supreme Court
    case holding that efforts by counsel to contact an in-
    custody suspect have no bearing on the validity of that
    suspect’s waiver of his Miranda rights. In reaching that
    conclusion, we relied on the fact that Connecticut ‘‘has
    had a long history of recognizing the significance of the
    right to counsel, even before that right attained federal
    constitutional importance.’’ 
    Id., 164. Importantly
    for present purposes, this court
    explained the significance of that history to be as fol-
    lows: ‘‘While this history specifically illuminates the
    right to counsel that attaches after the initiation of
    adversary judicial proceedings, it also informs the due
    process concerns raised by police interference with
    counsel’s access to a custodial suspect. Cf. State v.
    Ferrell, 
    191 Conn. 37
    , 42 n.5, 
    463 A.2d 573
    (1983).17 In
    recently reiterating that Miranda warnings are indepen-
    dently required under the due process clause of article
    first, § 8, of the Connecticut constitution; State v. Bar-
    rett, 
    205 Conn. 437
    , 447, 
    534 A.2d 219

    nized, once again, the unique ability of counsel to
    protect the rights of a client undergoing, or confronting
    the imminent possibility of, interrogation.

    ‘‘This recognition is in service of the traditional belief

    Ferrell, supra

    assist a suspect in making an intelligent and knowing
    decision whether to speak or stand mute, we have con-
    cluded that questioning of a suspect must cease once
    a clear request for counsel has been made. State v.

    [384 U.S.] 444, itself the benchmark in this area of law,
    required fully effective means of ensuring a suspect’s
    continuous right of access to counsel.’’ (Citation omit-
    ted; footnote added; internal quotation marks omitted.)
    State v. 
    Stoddard, supra
    , 
    206 Conn. 166
    .
    This court’s concern in Stoddard about police inter-
    ference with access to counsel in this setting echoes
    the problem of allowing a police officer to press forward
    with interrogation in the face of a statement that a
    suspect reasonably believes to be an invocation of his
    right to have counsel present.18 We find it significant in
    this regard that, in reliance on Miranda and its progeny,
    this court endorsed the stop and clarify rule and fol-
    lowed it for more than a decade prior to Davis. See
    State v. Anderson, 
    209 Conn. 622
    , 627–28, 
    553 A.2d 589
    (1989); State v. 
    Barrett, supra
    , 
    205 Conn. 448
    ; State
    v. 
    Acquin, supra
    , 
    187 Conn. 674
    –75. We reached this
    determination based on our conclusion that this rule
    was compelled under Supreme Court precedent. See
    State v. 
    Acquin, supra
    , 675 (noting origin of stop and
    clarify rule in Fifth Circuit case law and concluding
    that Supreme Court’s decision in ‘‘Edwards v. Arizona,
    [supra, 
    451 U.S. 477
    ] must be read to include this com-
    mon-sense Fifth Circuit rule, which was implicitly
    approved by the majority, and specifically stated in
    Justice Powell’s concurring opinion’’ [emphasis
    added]).
    Since Davis, our appellate courts have not consid-
    ered whether they would follow its modified legal stan-
    dard as a matter of state constitutional law. This court
    did summarily reject an argument that the stop and
    clarify rule should apply to prewaiver statements as
    a matter of state constitutional law, premised on an
    assumption that Davis would control postwaiver state-
    ments under our constitution. See State v. Hafford, 
    252 Conn. 274
    , 294 n.15, 
    746 A.2d 150
    , cert. denied, 
    531 U.S. 855
    , 
    121 S. Ct. 136
    , 
    148 L. Ed. 2d 89
    (2000). Putting
    aside the difference in the claim presented, it is well
    settled that, in the absence of a complete and proper
    constitutional analysis, we would not follow such a
    determination but, rather, assess the matter anew under
    the requisite analytical process. See, e.g., State v. Patel,
    
    327 Conn. 932
    , 939–40, 
    171 A.3d 1037
    (2017); State v.
    Piorkowski, 
    243 Conn. 205
    , 214, 
    700 A.2d 1146
    (1997);
    State v. Barton, 
    219 Conn. 529
    , 538–40, 
    594 A.2d 917
    (1991).
    Although this court has not previously addressed the
    precise question presently before us, many other juris-
    dictions have considered whether Davis should be fol-
    lowed under their state constitutions or common-law
    analogue. The numbers weigh in favor of the state’s
    position, by approximately a two to one margin.19 See
    State v. 
    Purcell, supra
    , 
    174 Conn. App. 435
    –36 and n.16
    (citing cases). Six jurisdictions that have reached this
    question have concluded that Davis should not be fol-
    lowed as a matter of state law.20 A seventh, West Vir-
    ginia, strongly suggested that it would do so when the
    question was presented; see footnote 19 of this opinion;
    and other jurisdictions have found other ways to mini-
    mize the potential harshness of the Davis rule.21 Ulti-
    mately, however, our concern is not the numerical tally
    of states but the persuasiveness of the decisions in
    those states. See State v. 
    Dickson, supra
    , 
    322 Conn. 431
    (‘‘We recognize that a number of courts have concluded
    otherwise. Nevertheless, we conclude that this is an
    issue for which the arc of logic trumps the weight of
    authority.’’); State v. 
    Jenkins, supra
    , 
    298 Conn. 262
    (‘‘a
    proper Geisler analysis does not require us simply to
    tally and follow the decisions favoring one party’s state
    constitutional claim; a deeper review of those decisions’
    underpinnings is required because we follow only per-
    suasive decisions’’ [internal quotation marks omitted]).
    A review of these cases reveals that, in large measure,
    they simply endorse the reasoning of the majority or
    concurring opinion in Davis; see, e.g., State v. Owen,
    
    696 So. 2d 715
    , 719 (Fla.) (finding reasoning of Davis
    majority persuasive), cert. denied, 
    522 U.S. 1002
    , 
    118 S. Ct. 574
    , 
    139 L. Ed. 2d 413
    (1997); State v. Hoey, 
    77 Haw. 17
    , 36, 
    881 P.2d 504
    (1994) (adopting reasoning
    of Davis concurrence); rely on the soundness of the
    rule adopted in that jurisdiction before Davis; see, e.g.,
    Steckel v. State, 
    711 A.2d 5
    , 10–11 (Del. 1998) (following
    clarification approach); Downey v. State, 
    144 So. 3d 146
    , 151 (Miss. 2014) (same); or both; see, e.g., State v.
    Chew, 
    150 N.J. 30
    , 63, 
    695 A.2d 1301
    (1997) (‘‘[g]iven
    the narrow balance for the Davis majority’s analysis,
    we believe it prudent to continue to apply our [stop
    and clarify] precedent’’). We therefore independently
    consider the merits of Davis.
    Before we commence that process, we explain why
    it is appropriate to undertake such a review. Since this
    court adopted Geisler, we generally have assumed that
    the federal precedent factor weighs against the defen-
    dant if the United States Supreme Court has squarely
    decided the issue to the contrary under the federal
    constitution; see, e.g., State v. 
    Piorkowski, supra
    , 
    243 Conn. 216
    ; or the federal courts are unanimous that the
    court would reach such a decision. See, e.g., State v.
    
    Lockhart, supra
    , 
    298 Conn. 550
    and n.6; State v. Ledbet-
    
    ter, supra
    , 
    275 Conn. 561
    . We have not considered the
    merits of the on point decision itself. However, there
    are compelling reasons to reconsider that approach, at
    least as applied to the circumstances of the present
    case. When, as in the present case, the issue to be
    decided is largely policy driven, it seems highly appro-
    priate to consider the soundness of the policy rationale
    supporting the Supreme Court’s decision.22 See, e.g.,
    State v. 
    Stoddard, supra
    , 
    206 Conn. 168
    –71 (in pre-
    Geisler decision, this court examined objections to rule
    requiring police to inform defendant of counsel’s efforts
    to communicate with suspect articulated in United
    States Supreme Court’s decision rejecting rule to deter-
    mine whether rule should be adopted under our state
    constitution). Indeed, as we previously noted, many of
    our sister states have rested their decisions solely on
    that basis. Moreover, if the Supreme Court decision
    under consideration results in a significant departure
    from precedent that this court has followed, as in this
    instance, this court has the responsibility to examine
    the Supreme Court’s reasons for doing so to aid us in
    our determination as to whether we should invoke the
    state constitution to stay the course or follow the
    Supreme Court and adopt the change. See, e.g., State
    v. Marsala, 
    216 Conn. 150
    , 160–69, 
    579 A.2d 58
    (1990)
    (pre-Geisler decision in which court examined sound-
    ness of reasons articulated in United States Supreme
    Court’s decision adopting good faith exception to exclu-
    sionary rule to determine whether rule is incompatible
    with our state constitution). In addition, if the factual
    assumptions or legal underpinnings of a prior decision
    have been materially undermined by events since the
    Supreme Court considered the matter, it is appropriate
    for us to reconsider the merits of the decision. Although
    we could address many of these matters under other
    Geisler factors, particularly, economic and sociological
    considerations, we conclude that the more logical
    approach is to consider the merits of a policy driven
    Supreme Court decision separate from other policy con-
    siderations.
    In doing so, we consider whether the underpinnings
    of the Supreme Court’s decision are so flawed or incon-
    sistent with this state’s case law or public policies that
    the decision should not be followed as a matter of state
    law. Cf. State v. Cardenas-Alvarez, 
    130 N.M. 386
    , 391,
    
    25 P.3d 225
    (2001) (recognizing that state court may
    diverge from federal constitutional precedent in inter-
    preting analogous provision of state constitution if,
    among other reasons, there is ‘‘ ‘a flawed federal analy-
    sis’ ’’); Morris v. Brandenburg, 
    356 P.3d 564
    , 573 (N.M.
    App. 2015) (citing state cases rejecting United States
    Supreme Court decisions that had been widely criti-
    cized as weakening right ‘‘ ‘beyond a point which may
    be countenanced under our state constitution,’ ’’ or as
    ‘‘ ‘unpersuasive and incompatible with state constitu-
    tional standards,’ ’’ or that had been criticized in legal
    literature as ‘‘ ‘devoid of a reasoned basis in constitu-
    tional doctrine’ ’’), aff’d, 
    376 P.3d 836
    (N.M. 2016).
    As we previously indicated, Davis was decided by a
    five to four margin. See Davis v. United 
    States, supra
    ,
    
    512 U.S. 452
    . The majority viewed the standard it articu-
    lated to be consistent with the court’s precedent. 
    Id., 458–60. However,
    prior to Davis, this court had inter-
    preted the court’s precedent as endorsing the stop and
    clarify rule. See State v. 
    Acquin, supra
    , 
    187 Conn. 674
    –
    75. This means that we agreed with the interpretation
    of the court’s precedent articulated by the Davis con-
    currence. See Davis v. United 
    States, supra
    , 467–70
    (Souter, J., concurring). Consistent with that view, this
    court itself subsequently characterized Davis as a
    change in the law, in that it ‘‘narrowed’’ the holding in
    Miranda ‘‘that when an accused person ‘indicates in
    any manner at any stage of the process that he wishes
    to consult with an attorney before speaking there can
    be no questioning,’ and the police must stop the interro-
    gation.’’ State v. 
    Anonymous, supra
    , 
    240 Conn. 720
    .
    The fact that Davis narrowed constitutional safeguards
    deemed by this court to be of ‘‘independent’’ signifi-
    cance under our state constitution; see State v. 
    Barrett, supra
    , 
    205 Conn. 447
    ; State v. 
    Ferrell, supra
    , 
    191 Conn. 45
    n.12; weighs against following Davis in the absence
    of countervailing considerations.
    The Davis majority also justified its rule in relation
    to the two sides of the Miranda equation—balancing
    the need to protect suspects from an inherently coercive
    interrogation environment against the need for effective
    law enforcement. See Davis v. United 
    States, supra
    ,
    
    512 U.S. 460
    –61. With regard to the suspect’s side of
    the equation, the Davis majority recognized that
    ‘‘requiring a clear assertion of the right to counsel might
    disadvantage some suspects who—because of fear,
    intimidation, lack of linguistic skills, or a variety of
    other reasons—will not clearly articulate their right to
    counsel although they actually want to have a lawyer
    present.’’ (Emphasis added.) 
    Id., 460. Nonetheless,
    it
    reasoned that ‘‘the primary protection afforded sus-
    pects subject to custodial interrogation is the Miranda
    warnings themselves. [F]ull comprehension of the
    rights to remain silent and request an attorney [is] suffi-
    cient to dispel whatever coercion is inherent in the
    interrogation process.’’ (Internal quotation marks omit-
    ted.) 
    Id. There are
    at least three flaws with this logic. The
    first flaw is that it incorrectly assumes that all suspects
    fully comprehend their Miranda rights and the effect
    of invoking them. Despite the ubiquity of Miranda
    warnings in television dramas that may lead the public
    to believe that everyone knows their rights, the evi-
    dence gathered since Davis is to the contrary. See gen-
    erally D. Dearborn, ‘‘ ‘You Have the Right to an
    Attorney,’ but Not Right Now: Combating Miranda’s
    Failure by Advancing the Point of Attachment Under
    Article XII of the Massachusetts Declaration of Rights,’’
    44 Suffolk U. L. Rev. 359, 364–87 (2011); R. Rogers et
    al., ‘‘ ‘Everyone Knows Their Miranda Rights’: Implicit
    Assumptions and Countervailing Evidence,’’ 16 Psychol.
    Pub. Policy & L. 300, 307–311 (2010); R. Rogers et al.,
    ‘‘The Language of Miranda Warnings in American Juris-
    dictions: A Replication and Vocabulary Analysis,’’ 32
    Law & Hum. Behav. 124 (2008) (analyzing verbal com-
    prehension of Miranda warnings). ‘‘[S]ocial science has
    demonstrated that suspects do not have a full apprecia-
    tion of either their rights or the effect of a waiver when
    they choose to speak to the police. . . . Social science
    has also found a disparity between the reading level
    required to comprehend the Miranda warnings and
    the reading levels of suspects who are expected to
    understand the warnings on their own. The evidence
    proves many warnings demand a greater educational
    background than many suspects possess. . . . Even
    assuming a custodial suspect understands the literal
    meaning of the words contained in the warnings, the
    constitutional principles embedded in those words are
    far from obvious. This unfortunate dynamic dispropor-
    tionately impacts vulnerable populations, including
    juveniles, the disabled, and individuals for whom
    English is not their first language. Yet even the [well
    educated] have difficulty understanding their Miranda
    warnings.’’ (Footnotes omitted; internal quotation
    marks omitted.) D. 
    Dearborn, supra
    , 373–75.
    Beyond that, the question of whether suspects under-
    stand their Miranda rights is largely distinct from the
    question of whether they know the unequivocal manner
    in which they would have to exercise those rights to
    give them effect, a piece of significant information that
    is not shared with them when they are given the warn-
    ings or before they are asked to waive their rights. With
    regard to the particular concern in the present case,
    although Davis requires a suspect to invoke his right
    to counsel clearly and unequivocally, almost 70 percent
    of defendants questioned in one study had no apprecia-
    tion for the precision required to request counsel and
    stop interrogation.23 See R. Rogers et 
    al., supra
    , 16 Psy-
    chol. Pub. Policy & L. 308 (defendants agreeing that,
    in seeking legal assistance, it means the same thing if
    you say, ‘‘ ‘I want a lawyer,’ ’’ or ‘‘ ‘I might want a law-
    yer’ ’’); see also R. Rogers, ‘‘A Little Knowledge Is a
    Dangerous Thing . . . Emerging Miranda Research
    and Professional Roles for Psychologists,’’ 63 Am. Psy-
    chologist 776, 777 (2008) (conservatively estimating
    that 318,000 suspects waive all their Miranda rights
    annually while failing to comprehend even 50 percent
    of representative Miranda warnings).
    The second flaw in the Davis majority’s logic is
    expressly acknowledged—that the underinclusiveness
    of its rule would disadvantage those individuals who are
    most likely to be subject to the very coercive pressures
    against which Miranda was intended to protect. See
    Davis v. United 
    States, supra
    , 
    512 U.S. 470
    n.4 (Souter,
    J., concurring) (‘‘Social science confirms what common
    sense would suggest, that individuals who feel intimi-
    dated or powerless are more likely to speak in equivocal
    or nonstandard terms when no ambiguity or equivoca-
    tion is meant. See W. O’Barr, Linguistic Evidence: Lan-
    guage, Power, and Strategy in the Courtroom [1982]
    61–71 . . . .’’). The Davis majority rule is akin to pro-
    viding fewer life preservers to passengers on board a
    boat who cannot swim or have conditions that make
    swimming difficult than to those without such
    impairments.
    A third, related flaw involves the Davis majority’s
    failure to appreciate that its rule would disproportion-
    ately disadvantage certain suspect or quasi-suspect
    classes, who more commonly rely on indirect speech
    patterns.24 ‘‘Sociolinguistic research has demonstrated
    that discrete segments of the population—particularly
    women and ethnic minorities—are far more likely than
    others to adopt indirect speech patterns.’’ J. 
    Ainsworth, supra
    , 103 Yale L.J. 261; see also 
    id., 317–18 (‘‘[O]ne
    researcher has observed that indirect speech patterns
    are common within African-American spoken language.
    In his pragmatic analysis of Black English, Thurmon
    Garner described what he termed a ‘strategy of indirec-
    tion’ by speakers as a linguistic mechanism to avoid
    conflict.’’ [Footnotes omitted.]). For example, hedges
    in speech, such as ‘‘I think,’’ ‘‘I suppose,’’ ‘‘maybe,’’ or
    ‘‘perhaps,’’ may be used to convey either that the
    speaker is uncertain about the statement or that the
    speaker prefers not to confront the addressee with a
    bald assertion. See 
    id., 276. As
    we observed in part II
    of this opinion, hedges are one type of such indirect
    speech that commonly is treated as equivocation or
    ambiguity under Davis.
    With regard to the other side of the Miranda equa-
    tion, the Davis majority reasoned that its rule was nec-
    essary for effective law enforcement. It posited that ‘‘if
    we were to require questioning to cease if a suspect
    makes a statement that might be a request for an attor-
    ney . . . [p]olice officers would be forced to make dif-
    ficult judgment calls about whether the suspect in fact
    wants a lawyer even though he has not said so, with the
    threat of suppression if they guess wrong.’’ (Emphasis
    omitted.) Davis v. United 
    States, supra
    , 
    512 U.S. 461
    .
    This reasoning is premised on a false choice, between
    requiring an unambiguous invocation of the right to
    counsel and permitting an ambiguous invocation of that
    right to require the termination of interrogation. The
    court ignores that the stop and clarify approach pro-
    vides a sensible middle ground, allowing law enforce-
    ment to dispel ambiguity and avoid guesswork as to
    the suspect’s actual intent. See Davis v. United States,
    United States Supreme Court Briefs, October Term,
    1993, Government’s Brief, p. 24 (‘‘[t]he ‘clarification’
    rule has the simple virtue of permitting the officer to
    solve that dilemma by seeking further information to
    ascertain the suspect’s choice’’).
    The Davis majority’s disregard of the stop and clarify
    approach in considering the needs of law enforcement
    is particularly difficult to understand in light of the
    position taken by the government and law enforcement
    amici in that very case. The government and the amici
    curiae Americans for Effective Law Enforcement, Inc.,
    International Association of Chiefs of Police, Inc.,
    National District Attorneys Association, Inc., and
    National Sheriffs’ Association all urged the court to
    adopt the stop and clarify rule, asserting that it struck
    the appropriate balance between the rights of suspects
    and the needs of law enforcement.25 See Davis v. United
    
    States, supra
    , 
    512 U.S. 467
    n.2 (Souter, J., concurring).
    The fact that a majority of jurisdictions had applied
    such a rule for many years before Davis suggests that
    there was an ample body of practical experience on
    which the amici could base their position.
    The Davis majority did concede that a stop and clarify
    approach often would be ‘‘good police practice.’’ 
    Id., 461. Of
    course, that fact, in and of itself, would not
    compel such a practice as constitutionally mandated.
    See United States v. Kahn, 
    415 U.S. 143
    , 155 n.15, 
    94 S. Ct. 977
    , 
    39 L. Ed. 2d 225
    (1974) (in fourth amendment
    context, police officers need not follow best practice
    in order for search to pass constitutional muster); State
    v. Marquez, 
    291 Conn. 122
    , 145, 
    967 A.2d 56
    (test for
    determining whether identification procedure is unnec-
    essarily suggestive ‘‘is not a ‘best practices’ test’’
    [emphasis in original]), cert. denied,

    , 
    130 S. Ct. 237
    , 
    175 L. Ed. 2d 163
    (2009). Nonetheless, the
    majority’s concession undermines its supposition that
    a more protective rule would unduly hamper effective
    law enforcement.
    In sum, we find the reasoning of the Davis majority to
    lack a sound basis in legal doctrine or law enforcement
    objectives. For the reasons that follow, we also con-
    clude that policy considerations that the Davis majority
    was not fully aware of, or did not acknowledge, support
    the more protective stop and clarify rule.
    The prophylactic rules adopted in Miranda and
    Edwards were intended as a countermeasure against
    the inherently coercive nature of custodial interroga-
    tions. See Miranda v. 
    Arizona, supra
    , 
    384 U.S. 457
    –58
    (‘‘It is obvious that such an interrogation environment
    is created for no purpose other than to subjugate the
    individual to the will of his examiner. This atmosphere
    carries its own badge of intimidation. . . . Unless ade-
    quate protective devices are employed to dispel the
    compulsion inherent in custodial surroundings, no
    statement obtained from the defendant can truly be
    the product of his free choice.’’ [Footnote omitted.]);
    Michigan v. 
    Harvey, supra
    , 
    494 U.S. 350
    (‘‘Edwards
    thus established another prophylactic rule designed to
    prevent police from badgering a defendant into waiving
    his previously asserted Miranda rights’’). However,
    there is reason to question whether these rules have
    proved adequate to the task. See generally D. 
    Dearborn, supra
    , 44 Suffolk U. L. Rev. 364–87. As we previously
    noted, studies show that many people do not have an
    accurate understanding of the protections afforded
    under Miranda or the manner for, and consequences
    of, invoking those rights. In addition, as one commenta-
    tor has observed, ‘‘[w]hat the [United States Supreme]
    Court did not (and perhaps could not) realize was that
    the forms of psychological coercion it sought to address
    would simply be refined and replaced with equally sinis-
    ter forms of manipulation.’’ 
    Id., 364–65. This
    problem
    has been exacerbated by the holding in Davis. By per-
    mitting interrogation to continue in the face of an ambig-
    uous invocation of the right to counsel, the police
    officers faced with such an invocation have been
    emboldened to employ a wide range of tactics designed
    to deflect suspects from clearly invoking their right to
    an attorney. See W. White, ‘‘Deflecting a Suspect from
    Requesting an Attorney,’’ 68 U. Pitt. L. Rev. 29, 31, 41
    (2006) (noting that most lower courts have interpreted
    Davis to allow interrogators to employ such tactics).
    The court in Miranda explained that the purpose of
    the warnings is to ‘‘show the individual that his interro-
    gators are prepared to recognize his privilege should
    he choose to exercise it.’’ Miranda v. 
    Arizona, supra
    ,
    
    384 U.S. 468
    . However, by allowing the police to con-
    tinue interrogating a suspect who has made a statement
    that he reasonably believes to be a request to have
    counsel present, the suspect reasonably would infer
    that the police do not intend to recognize his privilege.
    See Davis v. United 
    States, supra
    , 
    512 U.S. 472
    –73 (Sou-
    ter, J., concurring). Such a reasonable inference might
    not only dissuade subsequent efforts to renew that privi-
    lege, but also deter attempts to invoke other privileges.
    By contrast, as one commentator observed, ‘‘properly
    administered and narrowly limited questions designed
    to discern a suspect’s intent will not likely be viewed
    as coercive. In fact, it is more likely that such questions
    will impress upon the individual that the police are
    prepared to honor his choice but must first determine
    whether a choice has been made.’’ (Footnote omitted.)
    W. Holly, ‘‘Ambiguous Invocations of the Right To
    Remain Silent: A Post-Davis Analysis and Proposal,’’
    29 Seton Hall L. Rev. 558, 590–91 (1998).
    The court in Miranda also recognized the possibility
    of a coercive custodial interrogation resulting in a false
    confession. See Miranda v. 
    Arizona, supra
    , 
    384 U.S. 447
    , 455 n.24. The magnitude of this problem, however,
    was not known then, or even at the time Davis was
    decided. See Lapointe v. Commissioner of Correction,
    
    316 Conn. 225
    , 326, 
    112 A.3d 1
    (2015) (discussing role
    of social science research and advent of DNA testing
    in revealing scope of phenomenon); see also State v.
    Perea, 
    322 P.3d 624
    , 641 (Utah 2013) (‘‘[i]n the 1990s,
    little research had been conducted on the phenomenon
    of false confessions’’). Since Davis, the Supreme Court
    has recognized that ‘‘the pressure of custodial interroga-
    tion is so immense that it can induce a frighteningly
    high percentage of people to confess to crimes they
    never committed. Corley v. United States, 
    556 U.S. 303
    ,
    321 [
    129 S. Ct. 1558
    ,

    , 
    180 L. Ed. 2d 310
    (2011). Imposing an additional
    prophylactic measure may assist a system of criminal
    justice to prevent such results, without unduly hamper-
    ing legitimate law enforcement efforts. See State v.
    Francis, 
    322 Conn. 247
    , 266, 
    140 A.3d 927
    (2016) (‘‘[t]he
    value of any prophylactic rule . . . must be assessed
    not only on the basis of what is gained, but also on the
    basis of what is lost’’ [internal quotation marks
    omitted]).
    Recognizing that the promises that dwell within
    Miranda can only be achieved by honoring the premises
    upon which it rests, we determine that there are compel-
    ling reasons to conclude that Davis’ standard does not
    adequately safeguard Miranda’s right to the advice of
    counsel during a custodial interrogation. We therefore
    hold that, consistent with our precedent and the major-
    ity rule that governed prior to Davis, our state constitu-
    tion requires that, ‘‘if a suspect makes an equivocal
    statement that arguably can be construed as a request
    for counsel, interrogation must cease except for narrow
    questions designed to clarify the earlier statement and
    the suspect’s desire for counsel.’’ (Internal quotation
    marks omitted.) State v. 
    Anderson, supra
    , 
    209 Conn. 627
    –28. Interrogators confronted with such a situation
    alternatively may inform the defendant that they under-
    stand his statement(s) to mean that he does not wish
    to speak with them without counsel present and that
    they will terminate the interrogation. In either case,
    if the defendant thereafter clearly and unequivocally
    expresses a desire to continue without counsel present,
    the interrogation may resume. See, e.g., State v. 
    Acquin, supra
    , 
    187 Conn. 660
    , 669–70 (after defendant indicated
    that he wanted attorney and further clarification was
    sought, defendant later stated that ‘‘it wasn’t really an
    attorney that he wanted,’’ just someone he could trust,
    and asked for psychiatrist who worked with prisoners
    at his jail to be present).
    Applying that standard to the present case, we con-
    clude that the defendant’s rights under article first, § 8,
    of the Connecticut constitution were violated when the
    police officers continued to question him after the
    defendant ambiguously invoked his right to have coun-
    sel present. The officers’ response did not seek clarifica-
    tion of the defendant’s intent. Rather, they attempted
    to convince the defendant that it was against his inter-
    ests not to continue the interview. See United States
    v. March, 
    999 F.2d 456
    , 461–62 (10th Cir.) (‘‘clarifying
    questions must be purely ministerial, not adversarial,
    and cannot be designed to influence the subject not to
    invoke his rights’’), cert. denied, 
    510 U.S. 983
    , 114 S.
    Ct. 483, 
    126 L. Ed. 2d 434
    (1993); Thompson v. Wain-
    wright, 
    601 F.2d 768
    , 772 (5th Cir. 1979) (‘‘the limited
    inquiry permissible after an equivocal request for legal
    counsel may not take the form of an argument between
    interrogators and suspect about whether having coun-
    sel would be in the suspect’s best interests’’).
    The state makes no argument in its brief to this court
    that this constitutional violation was harmless beyond
    a reasonable doubt. See, e.g., State v. Newton, 
    330 Conn. 344
    , 353, 
    194 A.3d 272
    (2018) (if defendant demonstrates
    that constitutional violation exists, defendant is entitled
    to prevail unless state proves that violation was harm-
    less beyond reasonable doubt). Instead, it contends that
    suppression is not required on the grounds that (1) the
    sanction of exclusion does not apply because the police
    conducted themselves in objectively reasonable reli-
    ance on binding judicial precedent, and there is no claim
    that the statements were involuntary or untrustworthy,
    and (2) the police substantially complied with the stop
    and clarify rule and, in doing so, did not coerce or
    intimidate him. We are not persuaded by any of
    these contentions.
    Prior to our decision today, it was an open question
    whether this court would require a more protective rule
    under our state constitution. See State v. Pinder, 
    250 Conn. 385
    , 417, 
    736 A.2d 857
    (1999) (finding it unneces-
    sary to reach defendant’s claim that state constitution
    requires police to ask clarifying questions when its fed-
    eral counterpart does not); State v. 
    Anonymous, supra
    ,
    
    240 Conn. 717
    n.11 (declining to reach claim under
    state constitution because defendant did not provide
    independent analysis). Although we may assume that
    the officers were acting in good faith, we agree with
    the defendant that such a ‘‘good faith’’ type exception
    is incompatible with our case law. See State v. 
    Marsala, supra
    , 
    216 Conn. 169
    –71 (rejecting good faith exception
    to warrant requirements); see also State v. Brown, 331
    Conn. , ,         A.3d     (2019) (affirming that court’s
    rejection of good faith rule in Marsala was categorical
    and not amenable to case-by-case application). As we
    previously have stated, we do not agree that the police
    officers substantially complied with the clarification
    rule.
    The judgment of the Appellate Court is reversed and
    the case is remanded to that court with direction to
    reverse the judgments of the trial court and to remand
    the case to that court for a new trial.
    In this opinion the other justices concurred.

    The defendant does not concede that the complainant was his ‘‘victim.’’
    However, we use that term to conform to the Appellate Court’s recitation
    of facts, from which we quote at length in this opinion.
    4
    The defendant is not circumcised.
    5
    The defendant was arrested pursuant to three separate warrants issued
    in Wallingford, Fairfield, and Stratford, each of which correlated to one
    or more sites of the charged conduct. Those arrests took place between
    November, 2013, and February, 2014. The three cases were transferred
    to the judicial district of New Haven, where the defendant acquiesced to
    consolidation of the cases for trial.
    6
    It appears that Zerella assumed that the pictures of circumcised penises
    in the victim’s possession were of the defendant. The defense later estab-
    lished that the former did not depict the defendant because he is not cir-
    cumcised.
    7
    There was evidence submitted at trial that the victim had been diagnosed
    with autism. It appears that Fairbrother was likely referring to that condition.
    8
    General Statutes § 53-21 (a) provides in relevant part: ‘‘Any person who
    (1) wilfully or unlawfully causes or permits any child under the age of
    sixteen years to be placed in such a situation that . . . the morals of such
    child are likely to be impaired, or does any act likely to impair the health
    or morals of any such child, or (2) has contact with the intimate parts, as
    defined in section 53a-65, of a child under the age of sixteen years or subjects
    a child under sixteen years of age to contact with the intimate parts of such
    person, in a sexual and indecent manner likely to impair the health or morals
    of such child . . . shall be guilty of (A) a class C felony for a violation of
    subdivision (1) or (3) of this subsection, and (B) a class B felony for a
    violation of subdivision (2) of this subsection, except that, if the violation
    is of subdivision (2) of this subsection and the victim of the offense is
    under thirteen years of age, such person shall be sentenced to a term of
    imprisonment of which five years of the sentence imposed may not be
    suspended or reduced by the court.’’
    9
    We granted certification to appeal, limited to the following issues: ‘‘1.
    Did the Appellate Court properly determine that the defendant’s references
    to counsel during a custodial interrogation were ambiguous and equivocal
    and therefore did not constitute an invocation of his right to counsel?
    ‘‘2. Did the Appellate Court properly determine that article first, § 8, of
    the Connecticut constitution does not require that police ‘stop and clarify’
    an ambiguous or equivocal request for counsel?’’ State v. Purcell, 
    327 Conn. 959
    , 
    172 A.3d 800
    (2017).
    10
    In a subsequent case, the court held, also by a five to four margin, 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 at issue in Davis.’’ Berghuis v. Thompkins, 
    560 U.S. 370
    , 381, 
    130 S. Ct. 2250
    , 
    176 L. Ed. 2d 1098
    (2010); see also 
    id., 391 (Sotomayor,
    J., dissenting) (‘‘The [c]ourt . . . concludes that a suspect who
    wishes to guard his right to remain silent against such a finding of ‘waiver’
    must, counterintuitively, speak—and must do so with sufficient precision
    to satisfy a clear-statement rule that construes ambiguity in favor of the
    police. Both propositions mark a substantial retreat from the protection
    against compelled self-incrimination that Miranda . . . has long provided
    during custodial interrogation.’’).
    11
    In State v. Kono, 
    324 Conn. 80
    , 82 n.3, 122–24, 
    152 A.3d 1
    (2016), this
    court, following the approach we previously had adopted in State v. Santi-
    ago, 
    318 Conn. 1
    , 16 n.11, 
    122 A.3d 1
    (2015), explained that it is appropriate
    to consider the state constitutional claim first when the issue presented is
    one of first impression under both the state and federal constitutions or
    the issue is not settled under the federal constitution to such an extent that
    we can predict to a reasonable degree of certainty how the United States
    Supreme Court would resolve the issue. See State v. 
    Kono, supra
    , 82 n.3.
    In the present case, because we can predict to a reasonable degree of
    certainty how the United States Supreme Court would resolve the issue
    presented here under Davis, (that is, adversely to the defendant), it is
    appropriate to first explain why the defendant’s claim fails under the federal
    constitution before turning to the state constitutional issue.
    12
    The post-Davis cases are split as to whether the mere use of the term
    ‘‘I think’’ renders the statement equivocal. Compare Burket v. Angelone, 
    208 F.3d 172

    unequivocal request for counsel), cert. denied,

    more clear’’ invocation of his right to counsel. State v. Acquin,

    In a concurring opinion in Lucas, two justices concluded that these
    statements did not express an invocation of the right to counsel but, rather,
    an invocation of the right to remain silent. See Lucas v. 
    State, supra
    , 
    273 Ga. 91
    (Hunstein, J., concurring).
    14
    ‘‘[A]n accused’s postrequest responses to further interrogation may not
    be used to cast retrospective doubt on the clarity of the initial request itself.
    Such subsequent statements are relevant only to the distinct question of
    waiver.’’ (Emphasis omitted.) Smith v. 
    Illinois, supra
    , 
    469 U.S. 100
    .
    15
    For example, because the issue before us concerns the protection of
    Miranda rights—rights that were first recognized in 1966—historical
    insights into the intent of the framers as to this particular issue is not a
    relevant consideration.
    16
    We note that an argument could be made that, when considering whether
    to adopt a prophylactic rule to protect an established constitutional right,
    we need not engage in a Geisler analysis. Some commentators have argued
    that the appropriate analytical process is a policy centered weighing process
    similar to the one, described later in this opinion, that the Supreme Court
    relied on in Davis. See Davis v. United 
    States, supra
    , 
    512 U.S. 458
    (noting
    that whether to adopt prohibition on further questioning ‘‘is . . . justified
    only by reference to its prophylactic purpose’’); see, e.g., S. Klein, ‘‘Identifying
    and (Re)formulating Prophylactic Rules, Safe Harbors, and Incidental Rights
    in Constitutional Criminal Procedure,’’ 
    99 Mich. L
    . Rev. 1030, 1061–63 (2001)
    (arguing that court first determines whether rule providing relief only when
    there is showing that right actually has been violated is effective, and, if not,
    whether the proposed rule will be effective without imposing unacceptable
    costs); see also T. 
    Saylor, supra
    , 59 N.Y.U. Ann. Surv. Am. L. 299, 311–12
    (citing other formulations of prerequisites and describing core of inquiry
    as cost/benefit assessment). However, even some commentators who favor
    such weighing processes argue that any unique state concerns must be
    considered. See T. Aleinikoff, ‘‘Constitutional Law in the Age of Balancing,’’
    96 Yale L.J. 943, 1002–1004 (1987) (discussing potential alternatives to bal-
    ancing, including focused examination of items such as ‘‘text, structure,
    precedent, consequences, history, intent, our ‘ethical traditions’ [and]
    notions of fundamental values’’ [footnote omitted]); T. 
    Saylor, supra
    , 312–13
    (‘‘[j]ust as [under a primacy approach] state constitutional analysis should
    begin and end with the state constitution, unique state content, context,
    and sources should be deemed relevant in any balancing equation’’).
    This court previously has considered the Geisler factors in deciding
    whether to adopt a prophylactic rule under our state constitution; see, e.g.,
    State v. Harris, 
    330 Conn. 91
    , 114–31, 
    191 A.3d 119
    (2018); State v. Jenkins,
    
    298 Conn. 209
    , 259–82, 
    3 A.3d 806
    (2010); State v. Piorkowski, 
    243 Conn. 205
    , 214–21, 
    700 A.2d 1146
    (1997); see also State v. Lawrence, 
    282 Conn. 141
    , 158-77, 
    920 A.2d 236
    (2007); and the parties to the present case have
    briefed this issue under Geisler. Neither party advocated for a different
    approach. Nonetheless, we note that the outcome would be the same under
    either approach.
    17
    In State v. 
    Ferrell, supra
    , 
    191 Conn. 45
    , this court held that, because
    the right to consult with counsel is meaningless if the accused cannot
    privately and freely discuss the case, statements obtained without affording
    the privacy required to effectuate Miranda rights may not be admitted
    into evidence against a defendant in the state’s case-in-chief. The court
    emphasized that this holding was based not only on our interpretation of
    the fourteenth amendment to the United States constitution, but also on
    the alternative, independent state ground of the due process clause under
    article first, § 8, of the Connecticut constitution. 
    Id., 45 n.12.
        18
    In the present case, the Appellate Court dismissed the significance of
    Stoddard on the ground that this court had since ‘‘clarified the narrow
    confines of Stoddard . . . .’’ State v. 
    Purcell, supra
    , 
    174 Conn. App. 434
    .
    The Appellate Court is correct that this court declined to extend Stoddard
    to require the police to inform a juvenile suspect of his parent’s efforts to
    make contact; see State v. Whitaker, 
    215 Conn. 739
    , 751–52, 
    578 A.2d 1031
    (1990); concluded that Stoddard did not require the court to adopt a per
    se rule that a waiver of counsel can only occur in the presence of counsel;
    see State v. Piorkowski, 
    243 Conn. 205
    , 217–21, 
    700 A.2d 1146
    (1997); and
    that it did not require us to adopt a per se rule that the failure to record a
    defendant’s confession violates his right to counsel. State v. 
    Lockhart, supra
    ,
    
    298 Conn. 554
    . It is important to observe that, in each of these cases, the
    defendant was unable to offer persuasive precedent from this court or other
    courts, or compelling policy justifications for providing greater rights under
    our state constitution. In none of these cases did this court call into question
    the broader concerns articulated in Stoddard and its predecessors. See,
    e.g., State v. 
    Piorkowski, supra
    , 217 (discussing Stoddard and noting that,
    although our state constitution ‘‘scrupulously protects the right of an individ-
    ual’s access to counsel, we always have recognized that the right to counsel
    is a personal right’’). Moreover, the issue of whether a police officer can
    press forward with interrogation in the face of a statement that a suspect
    reasonably believes to be an invocation of his Miranda right to have counsel
    present is akin to the concern this court expressed in Stoddard regarding
    police interference with access to counsel.
    The state asserts that, ‘‘[e]ven more telling, in State v. Barrett, [supra,
    
    205 Conn. 447
    ], this court rejected the claim ‘that the due process clause
    contained in article first, § 8, of our state constitution require[d] a more
    expansive interpretation of the defendant’s invocation of his [Miranda] right
    to counsel . . . .’ ’’ The state ignores the fact that we limited our holding
    in Barrett to ‘‘the circumstances of this case’’; State v. 
    Barrett, supra
    , 447;
    which presented the unusual circumstance in which the defendant unambig-
    uously invoked his right to have counsel present for any written statement
    but similarly unambiguously waived his right to have counsel present for
    his oral statement. 
    Id., 448–49. Indeed,
    following the language on which the
    state relies, this court acknowledged that the warnings required by Miranda
    ‘‘are independently required under the due process clause of article first,
    § 8, of the Connecticut constitution.’’ 
    Id., 447. 19
          The Appellate Court cited thirteen jurisdictions adopting Davis under
    their respective state constitutions: California, Florida, Indiana, Iowa, Kan-
    sas, Mississippi, Montana, New Mexico, Tennessee, Texas, Washington, West
    Virginia, and Wisconsin. See State v. 
    Purcell, supra
    , 
    174 Conn. App. 435
    –36.
    It also cited three jurisdictions that had endorsed Davis as a matter of state
    law; see 
    id., 436 n.16;
    and two jurisdictions that had adopted Davis for
    postwaiver requests for counsel only. 
    Id. The parties
    agree that the majority of jurisdictions to consider this issue
    have resolved it in favor of the state’s position. We note, however, that the
    numbers are not quite as lopsided as the Appellate Court suggested. In the
    Mississippi case cited by our Appellate Court, Franklin v. State, 
    170 So. 3d 481
    , 491 (Miss. 2015), only a plurality of the court endorsed Davis and thus
    the case did not overrule that state court’s earlier decision rejecting Davis,
    which we have cited in footnote 20 of this opinion. Insofar as the Appellate
    Court included jurisdictions that adopted Davis’ standard for the question
    of an ambiguous invocation of the right to remain silent, such holdings
    would not necessarily dictate whether that standard would apply to an
    ambiguous invocation of the right to counsel. See, e.g., State v. Farley, 
    192 W. Va. 247
    , 256 n.12, 
    452 S.E.2d 50
    (1994) (The court, after applying the
    rule in Davis to conclude that the ambiguous invocation of the right to
    remain silent does not offend the state constitution, noted: ‘‘By using Davis
    . . . as an analytical starting point, we do not mean to infer that we are
    adopting Davis as part of West Virginia’s jurisprudence. . . . Given the
    coercive atmosphere, police pressure, secrecy, and the lack of sophistication
    of many criminal defendants, it would seem that an expression of reluctance
    to cooperate, at least insofar as it relates to an expression of an interest
    in the assistance of a lawyer, ought to be honored by the police. An
    approach, more consistent with Miranda itself, would be to follow the
    practice approved by a number of lower courts and, as urged by the concur-
    ring opinion in Davis, to require the interrogating officers to ask clarifying
    questions in order to clear up any ambiguity surrounding an interest in
    speaking with a lawyer. We note with interest that it took the Hawaii Supreme
    Court only three months to reject Davis in favor of the more reasonable
    stop-and-clarify approach.’’ [Emphasis added.]). In addition, in an Iowa case,
    three justices wrote separately to raise the question of whether the court’s
    prior case adopting Davis as a matter of state constitutional law has contin-
    ued vitality. See State v. Effler, 
    769 N.W.2d 880
    , 894–97 (Iowa 2009) (Appel,
    J., specially concurring), cert. denied, 
    558 U.S. 1096
    , 
    130 S. Ct. 1024
    , 175 L.
    Ed. 2d 627 (2009).
    20
    The following cases were decided under the jurisdiction’s state constitu-
    tion: Steckel v. State, 
    711 A.2d 5
    , 10–11 (Del. 1998); State v. Hoey, 
    77 Haw. 17
    , 36, 
    881 P.2d 504
    , 523 (1994); State v. 
    Risk, supra
    , 
    598 N.W.2d 648
    –49
    (Minnesota); Downey v. State, 
    144 So. 3d 146
    , 151 (Miss. 2014); State v.
    Charboneau, 
    323 Or. 38
    , 58–60, 
    913 P.2d 308
    (1996), cert. denied, 
    519 U.S. 1065
    , 
    117 S. Ct. 704
    , 
    136 L. Ed. 2d 625
    (1997). The Appellate Court’s tally
    of four omitted the Mississippi case; see footnote 19 of this opinion; and
    discounted the New Jersey case. We include State v. Chew, 
    150 N.J. 30
    ,
    62–63, 
    695 A.2d 1301
    (1997), in our tally because the mere fact that the right
    against self-incrimination under New Jersey law rests on a common-law
    privilege dating to the state’s origin, rather than a constitutional provision;
    see State v. Fary, 
    19 N.J. 431
    , 435, 
    117 A.2d 499
    (1955); does not make the
    court’s position any less significant in our view.
    21
    Even some jurisdictions purporting to apply federal law have mitigated
    the harshness of Davis’ rule though various approaches. See, e.g., People
    v. Kutlak, 
    364 P.3d 199
    , 206 (Colo. 2016) (assessing ambiguity of request
    by totality of circumstances, including ‘‘the speech patterns of the accused,’’
    ‘‘the accused’s behavior during interrogation,’’ and ‘‘the accused’s youth,
    criminal history, background, nervousness or distress, and feelings of intimi-
    dation or powerlessness’’); State v. Anderson, 
    258 So. 2d 44
    , 48, (La. App.
    2017) (citing pre-Davis case law in support of rule that, ‘‘[i]In analyzing
    whether there has been a direct, clear, unequivocal, and unambiguous
    request for counsel, courts must give a broad, rather than narrow, interpre-
    tation to the suspect’s request’’ [emphasis added]).
    22
    The state asserts that the federal precedent Geisler factor necessarily
    favors the state because Davis adopted a bright-line rule, and that the view
    of the four concurring justices is irrelevant because ‘‘the rule in Davis is a
    judicially prescribed prophylaxis, not a constitutional command . . . and
    nothing in the opinion of the concurring justices sheds any light on article
    first, § 8, of the Connecticut constitution.’’ In our view, the fact that the
    Davis rule is not a constitutional command affords more freedom to depart
    from federal precedent, not less. See Miranda v. 
    Arizona, supra
    , 
    384 U.S. 490
    (‘‘[s]tates are free to develop their own safeguards for the privilege, so
    long as they are fully as effective as those described above in informing
    accused persons of their right of silence and in affording a continuous
    opportunity to exercise it’’). With regard to the view of the concurring
    justices in Davis, the question they raised as to whether the majority’s rule
    was a departure from Supreme Court’s precedent—precedent that this court
    had followed—is necessarily a relevant consideration, as is any other con-
    cern they raised relevant to public policy considerations.
    23
    The study also reflected that more than 30 percent of defendants inaccu-
    rately believe that questioning can continue until their lawyers are physically
    present, and that a substantial minority do not believe they will have the
    opportunity to confer with counsel in private, thereby vitiating a primary
    advantage of seeking counsel. See R. Rogers et 
    al., supra
    , 16 Psychol. Pub.
    Policy & L. 311.
    24
    The Davis majority’s approach also is problematic in cases in which
    the defendant requires a translator, as he may make a statement that is
    subject to different interpretations in translation. See, e.g., United States v.
    De La Jara, 
    973 F.2d 746
    , 750–51 (9th Cir. 1992) (noting that interpreter
    offered three possible interpretations of defendant’s statements, and that
    ‘‘the meaning of [the defendant’s] statement is crucial, as the alternate
    translations have different legal effects’’); see also Vargas-Salguero v. State,
    
    237 Md. App. 317
    , 337, 
    185 A.3d 793
    (2018) (The defendant’s statement,
    translated from Spanish, ‘‘has two components that we need to unpack: the
    conditional opening [‘if I am being accused of something’] followed by the
    request itself [‘I better want an attorney’]. The first half of the sentence stated
    a condition, and a colloquial preface or qualifier can render a statement
    ambiguous. But the statement’s ultimate clarity depends on its context.’’
    [Emphasis omitted.]).
    25
    In its brief in Davis, the government went so far as to assert that the
    stop and clarify rule was the only approach that comported with the balance
    underlying Miranda and Edwards, and that a rule permitting clarifying
    questions provides a bright-line for the police and the courts to follow. See
    Davis v. United States, United States Supreme Court Briefs, supra, p. 23.
