    STATE OF CONNECTICUT v.
    CHRISTOPHER CALHOUN
    (SC 20497)
    Robinson, C. J., and McDonald, D’Auria,
    Mullins, Ecker and Alexander, Js.
    Syllabus
    Convicted of murder in connection with the shooting death of the victim,
    the defendant appealed to this court. The defendant had been arrested
    several years after the shooting, after two individuals, C and K, came
    forward and claimed to have witnessed the defendant shoot the victim.
    At trial, the state’s case rested almost entirely on the testimony of C
    and K, who were incarcerated both at the time of trial and when they
    first approached the police with information about the shooting. The
    trial court admitted into evidence the entirety of the cooperation agree-
    ments that C and K had with the state, and the prosecutor used those
    agreements to rehabilitate C and K during their respective direct exami-
    nations, before either witness had been impeached. Defense counsel
    thoroughly cross-examined C and K, including about their cooperation
    agreements, but the trial court precluded defense counsel from ques-
    tioning K about certain details of a prior arrest, which occurred after
    K testified before the grand jury in the present case and while he was
    released on parole. The trial court also declined defense counsel’s
    request for a jailhouse informant instruction with respect to C and K
    and, instead, gave the jury a special credibility instruction in which it
    noted that C and K had entered into cooperation agreements and urged
    the jury to examine their testimony with ‘‘careful scrutiny’’ and ‘‘particu-
    lar care . . . .’’ On the defendant’s appeal from the judgment of convic-
    tion, held:
    1. The trial court gave an adequate special credibility instruction and did
    not abuse its discretion in declining to give the requested jailhouse
    informant instruction:
    Although the trial court’s instruction was not in the exact form of the
    requested jailhouse informant instruction, the substance of the requested
    instruction was very similar to the instruction that the jury was given,
    the jury having been cautioned that C and K were receiving benefits
    from the state in return for testifying, that they might have a motive to
    lie, and that their testimony therefore should be examined with ‘‘careful
    scrutiny’’ and ‘‘particular care,’’ and, of all the witnesses who testified,
    the trial court singled out C and K as the only individuals whose credibility
    warranted such treatment.
    It was no consequence that the instruction the jury was given did not
    explicitly mention that C and K were incarcerated or identify them as
    jailhouse informants because, in light of the admission into evidence of
    the cooperation agreements, there was no need to warn the jury about
    the risk that C and K might be expecting a benefit from the state when
    the jury knew that they were expecting such a benefit.
    Moreover, the requested instruction was poorly suited to jailhouse infor-
    mants who, like C and K, were also eyewitnesses to the charged crime,
    as the requested instruction invited the jury to consider the extent to
    which the witness’ testimony contained details known only by the perpe-
    trator and the extent to which the details of the witness’ testimony could
    be obtained from a source other than the defendant.
    2. The trial court did not abuse its discretion in admitting the entirety of
    C’s and K’s cooperation agreements into evidence or in permitting the
    prosecutor to use those agreements during direct examination, before
    the witnesses had been impeached:
    The provisions in the cooperation agreements providing that, if the state’s
    attorney’s office or a judge determines that the witness is lying, then
    the witness will be subject to prosecution, did not serve to improperly
    vouch for the credibility of C and K, as those provisions did not imply
    that the state or the judge knew that the witnesses were telling the truth
    or that the state or the judge possessed information or means, unavailable
    to the jury, to determine the veracity of the witnesses’ testimony, and
    the references to prosecution in those provisions were truthfully stated
    and were not gratuitously repeated in the remainder of the cooperation
    agreements.
    Moreover, because defense counsel made it clear that she intended to
    cross-examine C and K about the cooperation agreements, it was within
    the trial court’s discretion to permit the prosecutor to use the cooperation
    agreements to rehabilitate C and K in advance, during direct examination.
    3. The trial court did not abuse its discretion in precluding defense counsel
    from cross-examining K about certain details of his prior arrest:
    The trial court properly allowed cross-examination of K on the fact that
    he gave the police a false name when, prior to his arrest, the police pulled
    over the car that he was driving, as that fact had special significance
    and directly related to K’s truthfulness, whereas it properly precluded
    cross-examination with respect to other details of K’s arrest, including
    the fact that his car smelled of marijuana and that he resisted arrest,
    neither of which related directly to K’s truthfulness.
    Notwithstanding the defendant’s argument that evidence regarding the
    smell of marijuana coming from K’s car and his resisting arrest contra-
    dicted his statement to the grand jury that he intended to give up his
    ‘‘criminal lifestyle,’’ the link between that evidence and K’s truthfulness
    was indirect at best, and the trial court reasonably could have concluded
    that any limited probative value of this evidence was outweighed by the
    potential to sidetrack the trial.
    Moreover, there was no merit to the defendant’s argument that the
    evidence surrounding the traffic stop was relevant to show that K would
    do anything, including falsely implicating the defendant, to avoid
    returning to prison, because, although the jury heard testimony that K
    gave a false name to the police when he was pulled over, and defense
    counsel was free to argue that giving false testimony was not so different,
    such an analogy did not extend as readily to the allegations involving
    marijuana and resisting arrest, and such an inference would have been
    too uncertain to require the trial court to admit such evidence.

    Procedural History
    Substitute information charging the defendant with
    the crime of murder, brought to the Superior Court in
    the judicial district of New Haven and tried to the jury
    before Alander, J.; verdict and judgment of guilty, from
    which the defendant appealed to this court. Affirmed.
    Kevin Smith, assigned counsel, with whom, on the
    brief, was Norman A. Pattis, assigned counsel, for the
    appellant (defendant).
    Nancy L. Chupak, senior assistant state’s attorney,
    with whom, on the brief, were Patrick J. Griffin, former
    state’s attorney, Kevin M. Black, Jr., former special
    deputy assistant state’s attorney, and Seth Garbarsky,
    senior assistant state’s attorney, for the appellee (state).
    Opinion
    ECKER, J. Isaiah Gantt was shot and killed in New
    Haven’s Church Street South housing project in April,
    2011. The crime went unsolved for many years, until
    two men, Eric Canty and Jules Kierce, came forward
    claiming to have been eyewitnesses to Gantt’s murder.
    Both men identified the defendant, Christopher Cal-
    houn, as Gantt’s killer. The defendant was arrested in
    2018 and charged with murder under General Statutes
    § 53a-54a (a). The outcome of the trial rested largely
    on the jury’s assessment of the credibility of Canty and
    Kierce. Their motivations were subject to impeachment
    because each of them was incarcerated when they first
    contacted the state about the case, and they each
    received consideration from the state in return for testi-
    fying pursuant to cooperation agreements. The jury
    returned a verdict finding the defendant guilty of mur-
    der.1 The defendant claims on appeal that the trial court
    made three erroneous rulings requiring reversal, namely,
    (1) declining to give the jury a jailhouse informant
    instruction, (2) admitting into evidence the entirety of
    Canty’s and Kierce’s cooperation agreements, and (3)
    not allowing defense counsel to cross-examine Kierce
    regarding certain details of a prior arrest. We affirm
    the judgment of conviction.
    The jury reasonably could have found the following
    facts. Gantt and the defendant both sold drugs in the
    Church Street South housing project. Although they had
    grown up as friends, they fell out when Gantt began to
    accuse the defendant of stealing customers. The eve-
    ning Gantt was killed, he openly confronted the defen-
    dant about stolen customers. Canty, a younger friend
    of the defendant, was present for this argument. The
    defendant told Canty to go home, but he hid nearby
    instead to see what would happen next.
    Around this time, Kierce, a mutual friend of Gantt
    and the defendant, received a series of phone calls from
    Gantt. Gantt sounded worried and asked Kierce to bring
    him a handgun that was hidden in a nearby apartment.
    As he spoke with Gantt, Kierce could hear an argument
    in the background. Kierce did not immediately get the
    gun for Gantt but went to see what was happening. He
    found Gantt and the defendant standing together with
    Montrell ‘‘Wooly’’ Dobbs. The atmosphere was tense.
    Kierce asked Gantt if he still needed the gun. Gantt said
    he did, so Kierce went to retrieve it for him.
    Kierce returned just in time to see the defendant
    shoot Gantt multiple times in the back. Canty saw the
    same thing from his hiding place in the alley. When the
    police arrived, Gantt had already died from his gunshot
    wounds. Later that night, Kierce encountered the defen-
    dant again, at the apartment of Latisha Parker. Although
    the two did not talk about the shooting, Kierce saw the
    defendant empty shells out of a gun and dump them
    into a toilet. A few days later, Canty also encountered
    the defendant, who at that time admitted to Canty that
    he had shot Gantt.
    At trial, the state’s case rested almost entirely on the
    testimony of Canty and Kierce. There was little other
    evidence inculpating the defendant. Ballistics and medi-
    cal evidence confirmed that Gantt had been shot and
    killed by a .22 caliber revolver in a manner consistent
    with the testimony of Canty and Kierce. One witness
    saw the defendant, Gantt, and Dobbs together on the
    evening of the murder and sensed that ‘‘something was
    up.’’ Another testified that the defendant had told her
    that Gantt was making too much money selling drugs
    and that Gantt had to stop or the defendant would
    make him stop. Otherwise, the case depended on the
    testimony of the two eyewitnesses, Canty and Kierce.
    Both Canty and Kierce were thoroughly cross-exam-
    ined by defense counsel. The jury learned that they
    each had criminal records and that each had entered
    into a cooperation agreement with the state. These
    agreements were admitted into evidence. The jury also
    heard testimony from the defense’s investigator. Accord-
    ing to this testimony, Kierce had contacted the defense
    team and told them that he was lying to the state and
    had not seen the defendant shoot Gantt.
    Ultimately, the jury needed to decide whether to
    credit the testimony of Canty and Kierce. The jury’s
    verdict speaks for itself. This appeal is narrowly focused
    on three issues: (1) the trial court’s failure to give the
    jury a jailhouse informant instruction; (2) its admission
    of the cooperation agreements; and (3) its refusal to
    allow cross-examination on the details of a prior arrest
    of Kierce.2
    I
    THE JAILHOUSE INFORMANT INSTRUCTION
    The defendant claims that the trial court abused its
    discretion by denying defense counsel’s request for a
    jailhouse informant instruction. Specifically, he con-
    tends that Canty and Kierce are jailhouse informants
    and that a special credibility instruction was therefore
    required by our holdings in State v. Patterson, 
    276 Conn. 452
    , 469, 
    886 A.2d 777
     (2005), and its progeny. We con-
    clude that the trial court provided an adequate special
    credibility instruction under the circumstances of
    this case.
    A jailhouse informant is any incarcerated witness
    who testifies to inculpatory statements made to him
    by the defendant. See State v. Bruny, 
    342 Conn. 169
    ,
    204–205, 
    269 A.3d 38
     (2022); see also State v. Jones,
    
    337 Conn. 486
    , 501, 508, 
    254 A.3d 239
     (2020). We have
    recognized that such testimony should be subject to a
    higher degree of scrutiny for three reasons: ‘‘(1) [the
    witness] ha[s] an unusually strong motive to [lie] . . .
    (2) confession evidence may be the most damaging
    evidence of all . . . and (3) false confessions are easy
    to fabricate, but difficult to subject to meaningful cross-
    examination . . . . [F]alse confession evidence from
    informants is the leading factor associated with wrong-
    ful convictions in capital cases and a major factor con-
    tributing to wrongful convictions in noncapital cases.’’
    (Citations omitted; emphasis in original; internal quota-
    tion marks omitted.) State v. Jones, supra, 501–502. In
    Patterson, we held that the trial court must warn the
    jury that jailhouse informant testimony should ‘‘be
    reviewed with particular scrutiny and weighed . . .
    with greater care than the testimony of an ordinary
    witness.’’ (Internal quotation marks omitted.) State v.
    Patterson, 
    supra,
     
    276 Conn. 465
    .
    We will assume for purposes of this opinion that
    both Canty and Kierce should have been considered
    jailhouse informants.3 We nonetheless conclude that the
    trial court gave an adequate special credibility instruction
    for both witnesses and did not abuse its discretion by
    declining to give the instruction requested by defense
    counsel. Although the trial court’s instruction was not
    in the exact form of the jailhouse informant instruction
    requested, it was good enough to warn the jury that
    Canty and Kierce had a powerful motivation to lie and
    that their testimony should be reviewed with scrutiny
    and weighed with greater care than that of an ordinary
    witness.
    ‘‘Our review of [an omitted jury instruction] requires
    that we examine the [trial] court’s entire charge to deter-
    mine whether it is reasonably possible that the jury
    could have been misled by the omission of the requested
    instruction. . . . If a requested charge is in substance
    given, the court’s failure to give a charge in exact confor-
    mance with the words of the request will not constitute
    a ground for reversal.’’ (Internal quotation marks omit-
    ted.) State v. Dehaney, 
    261 Conn. 336
    , 368, 
    803 A.2d 267
     (2002), cert. denied, 
    537 U.S. 1217
    , 
    123 S. Ct. 1318
    ,
    
    154 L. Ed. 2d 1070
     (2003). ‘‘[T]he language used in the
    model jury instructions, although instructive . . . is
    not binding on this court.’’ (Internal quotation marks
    omitted.) State v. Ortiz, 
    343 Conn. 566
    , 599, 
    275 A.3d 578
     (2022).
    In this case, the trial court gave the following special
    credibility instruction: ‘‘Two of the witnesses in this
    case, Eric Canty and Jules Kierce, testified that they
    entered into cooperation agreements with the state’s
    attorney’s office . . . . I must caution you to give care-
    ful scrutiny to the testimony of each of these witnesses
    in determining their credibility and the weight to give
    their testimony in this case. . . . In weighing their testi-
    mony, you may consider whether either witness’ testi-
    mony has been influenced by that agreement. You must
    therefore look with particular care at the testimony of
    such a witness before deciding to accept it as a basis
    for convicting the defendant in a criminal prosecution.’’
    The court also gave the standard general credibility
    instruction, explaining that, in assessing the credibility
    of each witness, ‘‘you may take into account a number
    of factors, including . . . (1) was the witness able to
    see or hear or know the things about which that witness
    testified? (2) How well was the witness able to recall
    and describe those things? (3) What was the witness’
    manner and demeanor while testifying? (4) Did the wit-
    ness have an interest in the outcome of this case? (5)
    How much time passed before the witness came for-
    ward with the information? (6) Did the witness have
    any bias or prejudice concerning any party or any matter
    involved in the case? (7) How reasonable was the wit-
    ness’ testimony in light of all the evidence in the case?
    And (8) was the witness’ testimony contradicted by
    what that witness said or did at another time, or contra-
    dicted by the testimony of other witnesses or by other
    evidence?’’
    Not given by the court was the jailhouse informant
    instruction requested by defense counsel: ‘‘[The]
    [s]tate’s witnesses, Jules Kierce and Eric Canty, who
    are currently incarcerated, testified in this case as infor-
    mants. At the time these witnesses first provided infor-
    mation to [the] police, they were also incarcerated for
    crimes unrelated to the crime in this case. When an
    informant testifies, as Mr. Kierce and Mr. Canty did
    here, their testimony must be examined with greater
    scrutiny than the testimony of an ordinary witness. You
    should determine the credibility of these witnesses in
    light of any motive that they may have [had] for testi-
    fying falsely and inculpating the accused. In considering
    the testimony of these two witnesses, you may consider
    [1] [w]hether the informants have received, been
    offered, or reasonably expect anything from the state
    . . . in exchange for their testimony that would moti-
    vate them to testify falsely against the defendant, [2]
    [a]ny belief they may have that these benefits are contin-
    gent [on] their ability to produce evidence of criminal
    conduct, [3] [a]ny other case in which the informants
    testified or offered statements against another individ-
    ual, and whether the informants received any deal,
    promise, inducement or benefit in exchange for their
    testimony or statements, [4] [w]hether the informants
    have ever changed their testimony/statement, [5] [t]he
    extent to which their testimony is confirmed by other
    evidence, [6] [t]he specificity of their testimony, [7] [t]he
    extent to which their testimony contains details known
    only by the perpetrator, [8] [t]he extent to which the
    details of their testimony could be obtained from a
    source other than the defendant, [9] [t]heir criminal
    record[s], and [10] [t]he circumstances under which
    they initially provided the information to the police or
    prosecutor.’’
    The substance of this requested instruction is very
    similar to the instruction that the jury in fact heard.
    The jury was cautioned that Canty and Kierce were
    receiving benefits from the state in return for testifying,
    that they might have a motive to lie, and that their
    testimony should therefore be examined with ‘‘careful
    scrutiny . . . .’’ This cautionary instruction took on
    special force because only Canty and Kierce, of all the
    witnesses who testified at trial, were singled out as
    individuals whose credibility warranted ‘‘careful scru-
    tiny’’ and ‘‘particular care . . . .’’ The jury also was
    encouraged to consider the source of the witnesses’
    knowledge, their potential bias, whether their testimony
    was corroborated by other witnesses, and whether they
    contradicted themselves.
    There are only two material respects in which the
    content of the instruction the defendant requested went
    beyond the instruction he received. In the circum-
    stances of this case, we conclude that neither difference
    misled the jury.
    First, the requested jailhouse informant instruction
    explicitly mentions that Canty and Kierce are incarcer-
    ated criminals and identifies them as jailhouse infor-
    mants. In the absence of a cooperation agreement, these
    facts are important because they suggest that the wit-
    nesses might be hoping for favorable treatment from
    the state in return for their testimony. In the context
    of this case, however, there was no need to warn the
    jury about the risk that Canty and Kierce might be
    expecting a benefit from the state because the jury
    knew that Canty and Kierce were expecting a benefit
    from the state. The witnesses had written cooperation
    agreements that had been admitted into evidence, and
    they each had been subject to extensive cross-examina-
    tion regarding, among other things, the benefits they
    hoped to receive from the state in exchange for their
    testimony. In this respect, the trial court’s instructions
    provided a stronger warning than the jailhouse infor-
    mant instruction the defendant requested. The former
    reminded the jury of the reality that Canty and Kierce
    expected to benefit by their testimony while the latter
    would have merely warned about the possibility of that
    expectation.
    Second, the requested jailhouse informant instruc-
    tion invites the jury to consider ‘‘[t]he extent to which
    [the witnesses’] testimony contains details known only
    by the perpetrator’’ and ‘‘[t]he extent to which the
    details of their testimony could be obtained from a
    source other than the defendant . . . .’’ This part of
    the jailhouse informant instruction is well suited to
    most jailhouse informants, but it is poorly suited to a
    jailhouse informant who is also an eyewitness. Canty
    and Kierce both claimed to be eyewitnesses, so it would
    make no sense to ask the jury to consider whether the
    details of their testimony could be known only by the
    defendant. The trial court was right not to give this part
    of the requested instruction. Jury instructions are not
    ‘‘one size fits all formulations,’’ which is why trial courts
    must sometimes modify jury instructions to meet the
    needs of a case. (Internal quotation marks omitted.)
    State v. Ortiz, supra, 
    343 Conn. 600
    .
    When the trial court’s jury instructions are read as a
    whole, and taken in the context of the case, it becomes
    clear that the substance of the requested jailhouse infor-
    mant instruction was given to the jury. Canty and Kierce
    both had cooperation agreements with the state pursu-
    ant to which they expected to benefit from their testi-
    mony, they were both eyewitnesses to the actual crime
    and could provide detailed testimony about what they
    observed, and they were both thoroughly cross-exam-
    ined on the details they witnessed, on their criminal
    records, and on their cooperation agreements. In these
    particular circumstances, the trial court did not err in
    providing a cooperating witness instruction along with
    a general credibility instruction, instead of the jailhouse
    informant instruction requested by defense counsel.
    II
    THE COOPERATION AGREEMENTS
    The defendant next claims that the trial court abused
    its discretion by admitting the entirety of Canty’s and
    Kierce’s cooperation agreements into evidence. These
    agreements provide that Canty and Kierce are obligated
    to tell the truth and may be prosecuted if they lie.
    The defendant contends that these provisions of the
    cooperation agreements constitute vouching for the
    witnesses and should not have been admitted. The
    defendant also contends that, even if these provisions
    could have been used to rehabilitate Canty and Kierce,
    the trial court abused its discretion in permitting the
    prosecutor to use them during direct examination,
    before the witness had been impeached. We disagree.
    Whether and when to admit the text of a cooperation
    agreement presents a sensitive issue for a trial court.
    Understanding the terms of a cooperation agreement
    can help the jury to assess the credibility of the witness.
    See Marquez v. Commissioner of Correction, 
    330 Conn. 575
    , 610–13, 
    198 A.3d 562
     (2019) (Palmer, J., concur-
    ring). However, it is also a document authored by the
    state, and, as we have recently observed, trial courts
    must ensure that prosecutors do not gain an unfair
    advantage from the way the cooperation agreement is
    drafted. See State v. Flores, 
    344 Conn. 713
    , 736, 740,
    
    281 A.3d 420
     (2022).
    Our case law has established a few rules to help guide
    trial courts undertaking this balancing act. First, it is
    well established that the prosecutor may use the text
    of a witness’ cooperation agreement to rehabilitate that
    witness after they have been impeached on the basis
    of their cooperation with the state. See id., 738. Second,
    if defense counsel indicates that they intend to cross-
    examine the witness regarding the benefits the witness
    may receive from the state in return for testifying, then
    the trial court has the discretion to permit the prosecu-
    tor to use the text of the agreement to rehabilitate the
    witness in advance, during direct examination, without
    waiting for defense counsel to impeach the witness.
    See id. Third, and regardless of whether the witness is
    impeached, the text of the cooperation agreement may
    not be used by the prosecutor to vouch for the witness.
    See id., 745–49.
    Vouching occurs when the state expressly or impliedly
    attests to the credibility of a witness. See, e.g., United
    States v. Roundtree, 
    534 F.3d 876
    , 880 (8th Cir. 2008).
    Although the state would not put on a witness it did
    not believe, the state’s confidence in its witnesses may
    not be stated or implied to the jury. The jurors’ assess-
    ment of a witness’ credibility should depend on their
    impression of the witness, not their faith in the probity
    of the state. Federal courts have identified several ways
    in which the text of a cooperation agreement might
    constitute impermissible vouching: (1) if the text in any
    way suggests that the prosecutor knows or believes
    that the witness is telling the truth; see United States
    v. Certified Environmental Services, Inc., 
    753 F.3d 72
    ,
    86–88 (2d Cir. 2014); (2) if the text in any way suggests
    the existence of facts outside the record that support
    the witness’ version of events; see United States v.
    Benitez-Meraz, 
    161 F.3d 1163
    , 1167 (8th Cir. 1998); or
    (3) if the text in any way suggests that the state has
    the means of determining whether the witness is lying
    and will use those means to ensure that the witness
    tells the truth. See United States v. Bowie, 
    892 F.2d 1494
    , 1498–99 (10th Cir. 1990); see also State v. Flores,
    supra, 
    344 Conn. 745
    –48. Vouching in any of these forms
    can never be presented to the jury.
    Closely related to vouching is the inclusion of gratu-
    itous references to the witness’ obligation to tell the
    truth, or to the possible consequences of lying. Such a
    reference is gratuitous if it is repetitive or goes beyond
    simply memorializing the agreement between the wit-
    ness and the state. We have noted that gratuitous refer-
    ences of this kind may constitute vouching in some
    cases. See State v. Flores, supra, 
    344 Conn. 749
    . More-
    over, because gratuitous references do not shed any
    new light on the agreement between the witness and
    the state, their probative value is negligible and out-
    weighed by their prejudicial effect. To avoid this danger,
    ‘‘the state must take care in drafting its cooperation
    agreements, and trial courts must carefully examine
    their language before admitting them fully into evi-
    dence.’’ Id., 736.
    The defendant contends that the following language,
    contained in both Canty’s and Kierce’s cooperation
    agreements, constitutes vouching: ‘‘Should it reason-
    ably be determined by a judge of the Superior Court
    or the state’s attorney’s office that [the witness] has
    given false, incomplete or misleading testimony or
    information . . . he shall thereafter be subject to pros-
    ecution for any state criminal offense of which this
    office has knowledge, including, but not limited to . . .
    perjury and hindering prosecution.’’ We disagree
    because we do not consider this provision to be vouch-
    ing.
    The provision states that, if the state, or a judge,
    determines that the witness is lying, then the witness
    will be subject to prosecution. As written, the provision
    does not imply that the state or judge knows that the
    witness presently is telling the truth, or that they pos-
    sess information or means, unavailable to the jury, to
    determine the veracity of the witness’ testimony. Although
    conditional statements, if not carefully drafted, may
    vouch for a witness, this provision of the cooperation
    agreements does not do so. Nor do we consider the
    statement regarding the consequences of lying—that
    the witness will be subject to prosecution—to be gratu-
    itous as drafted. A cooperation agreement may refer to
    the consequences of lying, as long as those consequences
    are accurately stated and not needlessly repeated. See
    State v. Flores, supra, 
    344 Conn. 748
    –49. The reference
    to prosecution is truthfully stated and is not gratuitously
    repeated in the rest of the cooperation agreement.
    Taken as a whole, therefore, the trial court did not abuse
    its discretion by admitting these cooperation agree-
    ments into evidence.
    We further conclude that the trial court did not abuse
    its discretion by permitting the prosecutor to use the
    cooperation agreements to fortify the credibility of
    Canty and Kierce during direct examination, before they
    were impeached by defense counsel. As we held in
    Flores, if defense counsel makes it clear that they intend
    to cross-examine a witness on that witness’ cooperation
    agreement, then the trial court has discretion to permit
    the state to use the text of the cooperation agreement
    to rehabilitate the witness in advance, during direct
    examination.4 See id., 738. Defense counsel in this case
    made it clear that she intended to cross-examine Canty
    and Kierce on their cooperation agreements. The trial
    court therefore did not abuse its discretion in permitting
    the prosecutor to use the cooperation agreements dur-
    ing the direct examinations of Canty and Kierce.
    III
    CROSS-EXAMINATION ON PRIOR MISCONDUCT
    Lastly, the defendant contends that the trial court
    abused its discretion in not allowing defense counsel
    to cross-examine Kierce about the details of a prior
    arrest.5 The following factual background is relevant to
    this claim. Two years before trial, Kierce testified to
    the grand jury about the defendant’s role in the murder.
    In this testimony, Kierce stated that he had come for-
    ward belatedly because he ‘‘wanted to do the right
    thing,’’ he ‘‘no longer wanted to be associated with the
    criminal lifestyle,’’ and he ‘‘wanted to make a clean
    break . . . .’’ After his grand jury testimony, Kierce
    was released on parole. He violated parole by
    absconding from a halfway house and was later arrested
    during a traffic stop and returned to prison. At trial,
    defense counsel wanted to ask Kierce about the details
    of the traffic stop that lead to his capture and return
    to prison. Specifically, defense counsel wanted the jury
    to hear that Kierce initially refused to pull his car over
    when signaled by the police, that there was an odor of
    marijuana coming from Kierce’s car, that Kierce initially
    gave a false name, and that he resisted arrest.
    Outside the presence of the jury, defense counsel
    argued that all these details were appropriate subjects
    for cross-examination, because they showed that Kierce
    would do anything to avoid returning to prison and that
    he was being untruthful when he told the grand jury
    that he was giving up his ‘‘criminal lifestyle.’’ The trial
    court ruled that defense counsel could ask Kierce about
    whether he was pulled over and whether he gave a false
    name to the police. The jury also heard from Kierce
    that he was returned to prison after being pulled over
    because he had absconded from the halfway house.
    The court did not allow defense counsel to ask about
    the other details of the arrest. We conclude that it was
    within the trial court’s discretion to make this eviden-
    tiary ruling.
    ‘‘The law in Connecticut on impeaching a witness’
    credibility provides that a witness may be cross-exam-
    ined about specific acts of misconduct that relate to
    his or her veracity.’’ State v. Annulli, 
    309 Conn. 482
    ,
    492, 
    71 A.3d 530
     (2013). However, ‘‘[t]he right to cross-
    examine a witness concerning specific acts of miscon-
    duct is limited in three distinct ways. First, cross-exami-
    nation may . . . extend [only] to specific acts of mis-
    conduct other than a felony conviction if those acts
    bear a special significance [on] the issue of veracity
    . . . . Second, [w]hether to permit cross-examination
    as to particular acts of misconduct . . . lies largely
    within the discretion of the trial court. . . . Third,
    extrinsic evidence of such acts is inadmissible.’’ (Inter-
    nal quotation marks omitted.) State v. Colon, 
    272 Conn. 106
    , 206, 
    864 A.2d 666
     (2004), cert. denied, 
    546 U.S. 848
    ,
    
    126 S. Ct. 102
    , 
    163 L. Ed. 2d 116
     (2005); see Conn. Code
    Evid. § 6-6 (b), commentary.
    Kierce was subject to extensive cross-examination
    on his criminal background, his possible bias, and his
    prior inconsistent statements. On the subject of the
    traffic stop, defense counsel was permitted to cross-
    examine Kierce on the fact that he was pulled over and
    the fact that he provided a false name. The fact that
    Kierce gave a false name to the police has special signifi-
    cance for his truthfulness, and the trial court was cor-
    rect to allow cross-examination on that fact. By con-
    trast, the other details of Kierce’s arrest—the
    allegations that he pulled over slowly, smelled of mari-
    juana, and resisted arrest—do not directly relate to his
    truthfulness. See, e.g., State v. Ortiz, supra, 
    343 Conn. 588
    ; Vogel v. Sylvester, 
    148 Conn. 666
    , 675–76, 
    174 A.2d 122
     (1961).
    The defendant argues that these facts contradict
    Kierce’s statement to the grand jury that he intended
    to give up his ‘‘criminal lifestyle.’’ Although the trial
    court may have acted within its discretion had it allowed
    the sought after cross-examination, it did not abuse its
    discretion in drawing the line where it did by prohibiting
    testimony about the smell of marijuana and allegations
    of resisting arrest. A court has discretion to exclude
    evidence of prior misconduct if the relevance of that
    evidence to the issue of veracity is outweighed by its
    tendency to delay or confuse the litigation. See State
    v. Annulli, supra, 
    309 Conn. 494
    –95. Other than provid-
    ing a false name to the police, the link between the
    details of the traffic stop and Kierce’s truthfulness was
    indirect at best. A single arrest on such charges does
    not provide compelling evidence that Kierce knowingly
    misled the grand jury. The excluded details would have
    added little to the jury’s overall impression of Kierce’s
    truthfulness, which was subject to extensive impeach-
    ment by defense counsel on other grounds. The trial
    court reasonably could have concluded that any limited
    probative value was outweighed by the potential to
    sidetrack the trial.
    For the same reasons, we reject the defendant’s claim
    that the evidence surrounding the traffic stop was rele-
    vant to show that Kierce would do anything—including
    falsely implicating the defendant—to avoid returning
    to prison. The jury heard that Kierce gave a false name
    to the police when he was pulled over. The defense
    was free to argue that giving false testimony was not
    so different. But the analogy does not extend as readily
    to the other allegations of wrongdoing involving mari-
    juana and resisting arrest. That inference is too uncer-
    tain to require the trial court to admit such evidence.
    See, e.g., State v. Pinnock, 
    220 Conn. 765
    , 782–83, 
    601 A.2d 521
     (1992) (trial court did not abuse its discretion
    by precluding cross-examination on details of cooperat-
    ing witness’ prior conviction); State v. Moye, 
    214 Conn. 89
    , 95–97, 
    570 A.2d 209
     (1990) (trial court did not abuse
    its discretion in concluding that misconduct evidence
    relating to witness’ failure to appear and respond to
    subpoena showed witness’ fear of committing perjury
    and, therefore, was relevant to his credibility). We con-
    clude that there was no abuse of discretion in limiting
    the cross-examination on the details of the traffic stop.
    The judgment is affirmed.
    In this opinion the other justices concurred.
    1
    The defendant was sentenced to forty-five years of incarceration.
    2
    The defendant appealed directly to this court pursuant to General Stat-
    utes § 51-199 (b) (3).

    In Bruny, we distinguished between jailhouse informants’ testimony
    about statements made by the defendant, on the one hand, and jailhouse
    informants’ testimony about their observations of events relating to the
    crime, on the other. See State v. Bruny, supra, 
    342 Conn. 205
    –206. We held
    that a special credibility instruction was mandatory for the former but not
    for the latter. 
    Id.
     In the present case, Canty testified about both his own
    eyewitness observations at the time of the murder and a statement the
    defendant made to him a few days later. See State v. Jones, supra, 
    337 Conn. 508
     and n.14 (requiring credibility instruction for jailhouse informant’s
    testifying both to statements made by defendant and observed events).
    The parties dispute whether Kierce’s testimony included more than his
    eyewitness observations during the events leading up to the murder. There
    is no need to resolve this dispute because we assume, arguendo, that Canty
    and Kierce both should have been treated as jailhouse informants. Our
    decision to do so does not alter the definition of jailhouse informants set
    out in Bruny and Jones.

    Flores was not decided when this trial occurred, but it is nevertheless
    controlling on appeal. See, e.g., State v. Elias G., 
    302 Conn. 39
    , 45, 
    23 A.3d 718
     (2011).

    The defendant frames this claim as an evidentiary issue, not a constitu-
    tional violation.
