    Indictments found and returned in the Superior Court
    Department on November 18, 2014.
    The cases were tried before Christopher J. Muse, J.
    Rebecca Rose for the defendant.
    Kathryn E. Leary, Assistant District Attorney, for the
    Commonwealth.
    MEADE, J.    After a jury trial, the defendant was convicted
    of three counts of assault and battery by means of a dangerous
    weapon and carrying a dangerous weapon.        After a separate jury
    trial, he was convicted of carrying a dangerous weapon as a
    second and subsequent offense.        On appeal, he claims that the
    2
    judge abused his discretion by not dismissing a juror and by
    denying a motion for a mistrial.    The defendant also claims that
    the prosecutor's opening statement and closing argument were
    errors that created a substantial risk of a miscarriage of
    justice.    We affirm.
    1.    Background.   On the night of June 6, 2014, off-duty
    State Police Trooper Peter Bien-Aime; his wife, Leslie Bien-
    Aime;1 and another couple, David Lebrun and Elizabeth Almeida,
    went out for the night in Boston.    Sometime after midnight, the
    group went to Venu (hereinafter, club), a night club located on
    Warrenton Street.
    After getting drinks, Peter and Lebrun were making their
    way back to Leslie and Almeida, who were conversing when the
    defendant approached the women.     The defendant, a short, skinny,
    black male with very short hair, wished to dance with Almeida;
    she had no interest.2    Upon seeing the two women upset, Lebrun
    and Peter approached the defendant, who greeted them by throwing
    a drink at them; the cup hit Peter in his face.    Pushing ensued,
    1 Given the married couple's identity of surname, we will
    refer to each by his or her first name.
    2 The defendant was accompanied by another man, who was
    described as being a tall black male with braids.
    3
    which resulted in intervention by Mercelino Amaro, the club
    manager.   The defendant was escorted out of the club.
    Outside the club, Boston police Officer Stephen Fabiano and
    Detective Kevin Guy, who were working a detail in the theater
    district, saw the defendant being removed from the club.3    They
    saw him yell at someone in the doorway and try to reenter the
    club a few times before he and his friend walked away on
    Warrenton Street in the direction of Stuart Street.
    Approximately thirty minutes later, the two couples left
    the club and began walking up Warrenton Street towards a parking
    lot where their car was parked.    While they walked, the group
    was approached by the defendant and the other man Peter had seen
    earlier in the club.4    They asked the group in a sarcastic manner
    if they were "the guys that were fighting, beating up those two
    people in [the club]."    The defendant began "violently" waving
    his hands around and stabbed Lebrun in his lower back.     When
    3 They described the defendant as a short, thinly built,
    black male.
    4 Peter recognized the two men from the earlier incident in
    the club. At first, Leslie and Lebrun did not recognize the two
    men from the earlier incident. Lebrun had not recognized the
    defendant at first because he had on a leather jacket when he
    approached them in the street. As the two men approached,
    Almeida did not recognize them from the earlier incident in the
    club. However, her physical description of the defendant, a
    short, skinny, black male, was consistent with her description
    of the man who threw the drink in the club.
    4
    Almeida screamed "what are you doing," the defendant grabbed her
    arm, spun her around, and stabbed her in the upper left back,
    next to her lungs, ribs, and spine.       Almeida immediately fell to
    the ground, and Leslie began screaming.      The defendant then
    swung at Peter and stabbed him just below his belt, piercing his
    clothing.    When the defendant attempted to flee, Peter tackled
    him.
    Officer Fabiano and Detective Guy saw the fight occurring
    from their position up the street.      They recognized both Peter
    and the defendant, who was one of the men who had been removed
    from the club.    The officers separated Peter and the defendant,
    who had been rolling on the ground and fighting.       The defendant
    struggled to get away, but Guy pinned him against a nearby
    parked bus.     Amaro, who followed the police down the street,
    also recognized the group from the earlier drink-throwing
    incident.     As the defendant was pinned against the bus, Amaro
    saw a knife fall to the ground between Guy and the defendant,
    and Amaro secured it by stepping over it (to block its use).
    After the fight, Lebrun identified the defendant as the
    person who stabbed them, and the defendant was arrested.       Peter
    also was arrested and transported to the police station where he
    was later released.
    2.   Discussion.   a.   Jury selection.   Juror number (no.)
    twelve's fears and concerns.      The defendant claims that he was
    5
    denied his right to an impartial jury because the judge abused
    his discretion when he declined to dismiss juror no. twelve, who
    expressed a concern about his ability to be impartial due to the
    stress of missing college classes.     We disagree.
    The Sixth Amendment to the United States Constitution and
    art. 12 of the Declaration of Rights of the Massachusetts
    Constitution guarantee criminal defendants trial by an impartial
    jury.   See Skilling v. United States, 
    561 U.S. 358
    , 377 (2010);
    Commonwealth v. McCowen, 
    458 Mass. 461
    , 494 (2010).      "We afford
    a trial judge a large degree of discretion in the jury selection
    process."    Commonwealth v. Vann Long, 
    419 Mass. 798
    , 803 (1995).
    See G. L. c. 234A, § 39.     The judge is duty bound to question
    potential jurors to ferret out any possible bias, prejudice,
    partiality, or whether there exists a substantial risk that the
    potential juror may be influenced by factors extraneous to the
    evidence at trial.     Commonwealth v. Andrade, 
    468 Mass. 543
    , 547
    (2014).     When evaluating juror impartiality, it is sufficient
    for the judge to inquire whether potential jurors can set aside
    their own opinions, properly weigh the evidence, and follow the
    judge's instructions.     
    Id. at 547-548.
       See Commonwealth v.
    Perez, 
    460 Mass. 683
    , 688-689 (2011).       "[A] determination by the
    judge that a jury are impartial will not be overturned on appeal
    in the absence of a clear showing of abuse of discretion or that
    the finding was clearly erroneous."     Commonwealth v. Andrade,
    6
    supra at 548, quoting from Commonwealth v. Lopes, 
    440 Mass. 731
    ,
    736 (2004).    See Commonwealth v. Ferguson, 
    425 Mass. 349
    , 352-
    353 (1997) (determination of juror impartiality "is essentially
    one of credibility"); Commonwealth v. Emerson, 
    430 Mass. 378
    ,
    384 (1999) ("A finding that a juror is impartial will not be
    overturned on appeal unless the defendant makes a clear showing
    of abuse of discretion or that the finding was clearly
    erroneous").
    The judge conducted the empanelment process and asked the
    prospective jurors questions along the lines prescribed by G. L.
    c. 234, § 28.5    During this process, the judge inquired whether
    juror no. twelve had raised his hand to any of the questions.
    The juror indicated that he had done so in response to the
    judge's question regarding whether the length of the trial would
    be a burden.     The juror explained that he was a student at
    Northeastern University (university) and that serving as a juror
    would "significantly impact" his course work.     The judge
    informed the juror that he would not excuse him for that reason,
    and that the university would support his service as a juror.
    Juror no. twelve agreed and had no other questions.     Neither
    party exercised any form of challenge to the juror.
    5 General Laws c. 234, § 28, was repealed after the
    defendant's trial. See St. 2016, c. 36, § 1. For the current
    applicable statute, see G. L. c. 234A, § 67A.
    7
    At the end of the first day of trial, juror no. twelve sent
    the judge a note stating, "I believe that the stress of missing
    school will result in an impartial [sic] decision on my part.      I
    am terrified that I will fail my classes and do not know if I
    can make a fair decision in the near future."     The judge was
    understandably troubled by the note and questioned juror no.
    twelve at sidebar.   The judge explained that jury service by
    college students in the Boston area was in no way unique and
    that it was a great opportunity to be given such a
    responsibility as a young adult.   He told the juror that many
    other students have had the same concerns and that the
    universities are required to make accommodations for jury
    service.   The juror understood, but he remained concerned about
    missing classes and having to make up the work.    The judge
    understood the juror's concerns, wanted him to be "comfortable"
    with his jury service, and instructed him to speak to university
    officials about what accommodations they would make for him and
    to report back to the judge the next day.    The juror agreed,
    noted that he had already contacted the registrar's office, and
    told the judge that he "definitely want[ed] to participate in
    [his] civic duty," but remained concerned.   After reassuring the
    juror that the university would permit him to make up the work
    he missed, the juror agreed to do as the judge requested.
    8
    The next morning, after the judge confirmed with juror no.
    twelve that the university would make accommodations for his
    jury service, the judge nevertheless inquired whether the juror
    could be fair to the defendant and give his attention to the
    judge's instructions and the evidence.     The juror responded, "I
    would definitely do my best, but I can't promise anything."       On
    further inquiry, the juror explained that he feared falling
    behind in his class work, but then indicated that he would "man
    up" and do his best.
    At the conclusion of the colloquy, the judge told the juror
    he was "a perfect candidate" to make sure the right result was
    reached, to which the juror responded, "I simply don't know."
    The judge decided to continue with the trial and to keep the
    juror seated.   Defense counsel requested that the juror be
    struck for cause.     The judge explained that he would "keep [him]
    as a work in progress, and assured counsel that he would not
    keep the juror for deliberation if "he's impaired."
    "As a general principle, it is an abuse of discretion to
    empanel a juror who will not state unequivocally that he or she
    will be impartial."     Commonwealth v. Colton, 
    477 Mass. 1
    , 17
    (2017).   However, evaluating a juror's use of seemingly
    equivocal language to make that determination lies within the
    judge's discretion.     Here, in response to the judge's questions,
    the juror said he would do his "best" but could not "promise
    9
    anything."   The judge reasonably could have concluded that these
    responses merely reflected the juror's habits of speech,
    contrast Commonwealth v. Vann 
    Long, 419 Mass. at 804
    & n.5
    ("statements that [the juror] 'would hope' he could be fair to
    the Cambodian defendant were not habits of speech, but
    indications of ethnic bias"), or were, at bottom, "not
    determinative of the juror's ability to be impartial."
    Commonwealth v. Jaime J., 
    56 Mass. App. Ct. 268
    , 274 (2002).
    See Commonwealth v. Prunty, 
    462 Mass. 295
    , 302 (2012) (no abuse
    of discretion to retain African-American juror who stated he
    "would be able to do my best" to not let defendant's racial
    prejudice affect juror's ability to be impartial); Commonwealth
    v. 
    Colton, supra
    (no abuse of discretion to empanel juror who,
    when asked if she could be fair to both sides, responded, "Yes,
    I think so," which "could be viewed as unequivocal").6   See also
    6 In Commonwealth v. 
    Colton, supra
    , the Supreme Judicial
    Court cited Commonwealth v. Vann 
    Long, 419 Mass. at 804
    , in
    support of the general principle that jurors need to be
    unequivocally impartial. In Vann Long, where a juror expressed
    that he "would really hope" that he could be fair to the
    Cambodian defendant, the court held that the judge abused his
    discretion by seating that juror, who harbored an ethnic bias
    against Cambodians. 
    Ibid. Of course, nothing
    of the kind
    appears on this record. In fact, more in line with this case,
    is another response from the juror in Vann Long, where he
    indicated that because his mother suffered from terminal breast
    cancer, he was "afraid [he] would be a little impatient here,
    especially with the deliberations. I will want to get out of
    here." 
    Id. at 799.
    As in this case, the judge did not treat
    10
    Commonwealth v. Wilborne, 
    382 Mass. 241
    , 254 (1981) (no abuse of
    discretion in empanelling juror who stated that she "did not
    think" that her friend's experience as rape victim would affect
    juror's ability to be impartial); Commonwealth v. Ascolillo, 
    405 Mass. 456
    , 459 (1989) (no abuse of discretion in empanelling
    juror whose final answer was, "No, I don't think so," to judge's
    inquiry whether juror's experience as police officer and assault
    victim would make him partial).   Also, that juror no. twelve
    expressed some uncertainty with the judge's assessment of the
    juror being a perfect candidate for jury service did not require
    the judge to find that uncertainty to be an indicator of
    partiality any more than humility.
    Unlike this court's review of the cold record, the judge
    was uniquely situated to measure juror no. twelve's demeanor and
    credibility.   Although early on in the judge's inquiry, the
    juror stated his concern about his ability to be "impartial,"
    the judge did not end the matter there.   Instead, he conducted a
    careful and thorough examination of the matter, after which the
    judge was in a better position to evaluate and to credit (or
    discredit) the motivation and the effect of the juror's stated
    concerns.   Compare Commonwealth v. Auguste, 
    414 Mass. 51
    , 57
    the juror's expression of frustration with the length of the
    trial as an indicator of partiality.
    11
    (1992) (finding abuse of discretion where judge's inquiry
    "avoided the very issue" of juror's ability to be impartial and
    coerced juror's responses).   Our review of the record supports
    the judge's apparent determination that the juror's "doubts
    about his . . . own impartiality [were] unfounded," 
    id. at 58,
    and were not an indicator of partiality at all.   While the juror
    classified his stress and concern about falling behind in his
    class work under the label of partiality, the judge was not
    required to credit what the juror reported.   See Commonwealth v.
    
    Ferguson, 425 Mass. at 352-353
    .   However, even if the judge did
    credit the juror's scholastic concerns, those concerns are not a
    basis to discharge a juror.   As we held in Commonwealth v.
    Campbell, 
    51 Mass. App. Ct. 479
    , 483-484 (2001), "A juror's
    complaints about the length of the proceedings, or expressions
    of frustration about having to serve as a juror, do not
    necessarily reflect the juror's inability to perform his or her
    function as an impartial trier of fact and, therefore, it is
    properly within the trial judge's discretion to refuse to
    discharge such a juror."   See Commonwealth v. Mabey, 
    299 Mass. 96
    , 99 (1937) (no indication that jury were unable or unwilling
    to give full and careful consideration to evidence in spite of
    foreperson's statements that jury were beginning to "get kind of
    jumpy" and that "[w]e [the jury] are just dying to get out").
    12
    Indeed, at its core, this juror's concerns centered on his
    frustration about the inconvenience inherent in performing jury
    service.     It did not reflect partiality or bias such that
    retaining him constituted reversible error.     See Commonwealth v.
    Campbell, supra at 483, citing Commonwealth v. Vann 
    Long, supra
    at 804 & n.5.    Instead, juror no. twelve's concern about missing
    his classes was a "run-of-the mill frustration[] by an
    exasperated juror about the judicial process," which is "to be
    expected."    Commonwealth v. Campbell, supra at 484.   Notably,
    after the judge's thorough colloquy, the juror never again
    raised his concerns regarding his stress from the length of the
    trial and its impact on his course load.     Indeed, in his written
    findings,7 the judge wrote that when juror no. twelve returned to
    the trial (after having conferred with the university), the
    juror was "satisfied that he could continue with his service.
    The [judge] found that there was no reason to discharge him."
    Fairly read, the judge concluded that the juror could perform
    his function impartially.     Given these findings, the judge's
    7 Prior to deliberations, the judge denied a motion from
    both parties to dismiss juror no. twelve. The Commonwealth also
    filed a petition pursuant to G. L. c. 211, § 3, seeking the
    discharge of juror no. twelve. In response, the judge filed
    written findings, which the defendant does not challenge,
    explaining his denial of the motion to discharge the juror. A
    single justice of the Supreme Judicial Court denied the
    Commonwealth's petition.
    13
    decision to retain the juror was not an abuse of discretion
    where the judge could properly conclude that he had allayed the
    juror's school work concerns so that the juror could render an
    impartial verdict based on the evidence.   See Commonwealth v.
    Ferguson, supra; Commonwealth v. 
    Colton, 477 Mass. at 16-17
    .      In
    other words, even though it might have been our choice in the
    first instance to have excused this juror, it falls outside our
    appellate office to substitute our judgment for the judge, who
    conducted the colloquies, assessed the juror's demeanor, and
    subsequently credited the juror's statements as being
    unequivocal.8   See Commonwealth v. Ferguson, supra at 352-354.
    The decision the judge made was neither a "clear error of
    judgment," nor did his "decision fall[] outside the range of
    reasonable alternatives."   L.L. v. Commonwealth, 
    470 Mass. 169
    ,
    185 n.27 (2014) (citation omitted).
    Juror no. twelve's opinion of the law.   The defendant also
    claims that juror no. twelve should have been dismissed after he
    spoke of jury nullification and expressed his disagreement with
    a point of law from the judge's instructions.   We disagree.
    8 The dissent maintains that "[t]he judge is required to ask
    them if they can be [fair and impartial], and to take them at
    their word" (emphasis supplied). Post at         . This "rule,"
    advanced without support, would strip the judge of any
    discretion to assess a juror's credibility and would relegate
    our appellate role to simply determining whether all of the
    "magic words" had been spoken in the colloquy.
    14
    After the judge completed his instructions to the jury, but
    before deliberations began, juror no. twelve sent a note to the
    judge stating, "I believe I may know information that would
    affect my ability to judge the case based solely on the
    information received in the trial."     When questioned by the
    judge, the juror clarified that he had not been exposed to
    extraneous evidence, but that he had "heard about how the jury
    actually has more power than [the judge] expressed, that [the
    jury] can judge not only based on just information, but whether
    they believe the law is fair, or their personal convictions
    . . . to judge guilty or not guilty."    The judge explained that
    this was known as jury nullification, and that it was not
    permitted.   The judge further explained that although he cannot
    instruct the juror on how to deliberate, he told the juror that
    the jury determine what the facts are, and that the jury must
    accept the judge's statement of the law regardless of the jury's
    agreement with it.   The judge queried whether juror no. twelve
    had any question regarding his ability "to take the law as I
    gave it to you, and apply it to the facts as you and [the] other
    jurors find them?"   The juror responded, "I don't think so."
    Sensing some hesitancy, the judge again explained the two
    different roles performed by the judge and the jury, and
    reiterated his instructions on the elements of the charged
    offenses.
    15
    Although agreeing with much of what the judge explained,
    juror no. twelve stated that he did not believe it should be
    unlawful to possess a small knife.    The judge further explained
    that it was not just that the knife's blade must be more than
    one-and-one-half inches, but that the knife must also have a
    case that enables the knife to be drawn in a locked position.
    See G. L. c. 269, § 10(b).   After this explanation, the judge
    asked the juror if he had any problem applying that law, to
    which the juror said, "I guess not."    Not satisfied with the
    juror's response, and sensing that the juror may nevertheless
    disagree with the law, the judge further instructed that the
    juror had to apply the law even if he disagreed with it.   The
    juror responded that he "thought that the jury had the power to
    choose whatever way to --," whereupon the judge interrupted and
    said, "I just told you it doesn't."    The juror said, "Okay."
    The judge continued to explain the importance of the jury
    understanding their obligations and that there should not be any
    hesitancy.9   The judge then asked if the juror was able to apply
    9 The juror asked if there was "punishment if the jury does
    not --" The judge interrupted, believing that the juror was
    concerned about punishment of the defendant, and told the juror
    not to worry about punishment and to only judge the facts. The
    juror indicated his understanding by saying, "Okay." Contrary
    to the dissent's suggestion, the judge did not tell the juror
    that he would be punished if he engaged in jury nullification.
    See post at        .
    16
    the law to the elements as the judge explained, and juror
    replied, "Yes."   The judge then painstakingly went through his
    other "major" jury instructions to ascertain whether the juror
    had any problem applying those instructions, and juror said he
    had no problem.   Finally, the judge asked, in reference to jury
    nullification, whether the juror was able to forget about "what
    other people have told [him]."   The juror agreed that he could,
    and that he could be fair and honest to his oath.     When the
    judge asked if the juror was "all set," the juror replied that
    he was and thanked the judge for speaking with him.    The judge
    thanked the juror and shared his appreciation for the juror
    having the courage to speak up and resolve his concerns.10
    At the close of this colloquy, defense counsel renewed his
    request that the juror be discharged, and the prosecutor joined
    the request.   In response, the judge explained to both counsel
    how the juror's concerns were resolved, that the juror would put
    aside his personal beliefs, would not engage in jury
    nullification, and was able to serve dispassionately with full
    10Given this ending to the colloquy, we have difficulty
    crediting the defendant's characterization of the judge's
    colloquy as an "interrogation," or that it was "coercive."
    Rather, the judge never dropped his proper neutral role, and
    went to great lengths to resolve the juror's concerns and
    misconceptions. Equally unavailing is the dissent's claim that
    when the judge asked the juror if the juror could apply the law
    as the judge instructed, "[Y]es" was the only answer the judge

    attention to the case.     The judge explained that he "went to
    great pains to give [the juror the] security of being able to be
    a juror as well as a student, . . . and [the judge did not] find
    any reason to discharge [the juror] after the colloquy that
    [they] engaged in."     Counsels' objections were noted.
    Contrary to the defendant's claim, the juror did not
    continually express his inability to be impartial and to apply
    the law as given.     As the juror admitted, he was not exposed to
    any extraneous information.     Instead, and apparently, the juror
    had been apprised of the concept of jury nullification.     The
    judge properly explained that jury nullification was not
    permitted and would be a violation of his oath to apply the law
    as given.   See Commonwealth v. Kirwan, 
    448 Mass. 304
    , 319 (2007)
    ("Jury nullification is inconsistent with a jury's duty to
    return a guilty verdict of the highest crime proved beyond a
    reasonable doubt").     See also Commonwealth v. Paulding, 
    438 Mass. 1
    , 9 (2002) (jury may not "exercise clemency"; their
    verdict may not be "contrary to the facts or the law of the
    case," and that verdict may not be an effort "to control the
    punishment which they think should be imposed on the defendant
    for his crime"), quoting from Commonwealth v. Dickerson, 
    372 Mass. 783
    , 812 (1977) (Quirico, J., concurring).     Cf. art. 30 of
    18
    the Massachusetts Declaration of Rights (Commonwealth is "a
    government of laws and not of men").11
    When juror no. twelve told the judge that he did not agree
    with the law regarding the knife as a dangerous weapon, the
    judge first discussed the issue with the juror and clarified
    what the law was.    After this explanation, the judge asked the
    juror if he had any problem applying that law, to which the
    juror said, "I guess not."    Not satisfied, the judge asked
    additional questions, which culminated in the juror agreeing
    that he would be able to apply the law to the elements as the
    judge explained.    As an added measure of caution, the judge
    returned to other major portions of his instructions to
    ascertain the juror's proper understanding of his role.
    Contrary to the defendant's claim, the judge addressed the
    juror's "initial uncertainty competently" by "ask[ing] probing
    questions designed to clarify the juror's position."
    Commonwealth v. Jaime 
    J., 56 Mass. App. Ct. at 275
    .    Based on
    the juror's response that he could apply the law as instructed,
    the judge did not abuse his discretion in crediting the juror's
    response and declining to discharge the juror.    "We defer to the
    judge's conclusion not to excuse this juror, because he had the
    11To the extent the dissent claims that it would be
    erroneous to instruct a jury that they lacked the power to
    nullify a verdict, see post at        , the defendant makes no
    such claim and the matter is not before us.
    19
    opportunity to observe [the juror's] demeanor while he
    questioned [the juror] at some length, and because [the juror's]
    answers to his probing questions allayed any concerns he might
    have had."    Commonwealth v. Seabrooks, 
    433 Mass. 439
    , 443-444
    (2001).12    The judge was within his discretion to decline to
    dismiss juror no. twelve.13
    b.     Late disclosed discovery.   After the second day of
    trial, the Commonwealth disclosed eighty-five crime scene
    photographs and an eighteen-page crime scene response report
    with diagrams showing the location of the knife.      In response,
    the defendant requested a mistrial on the ground that the
    prejudice to the defense was too great to overcome because
    12In his written findings, see 
    n.7 supra
    , the judge
    expressly found that the juror "indicated to the satisfaction of
    this judge that he would apply the law."
    13The defendant properly acknowledges that it is improper
    for a juror to disregard the law as given by the judge, but
    claims that the judge should have instructed the juror that it
    remained within his power to "vote his conscience." However,
    the defendant never requested that the judge so instruct, and
    has failed to identify any authority that would have required
    the judge to have done so sua sponte. Pursuing the matter from
    an angle not raised by the defendant, the dissent claims that
    "it also cannot be permissible to instruct a juror falsely that
    he or she lacks the power to vote his or her conscience." Post
    at        . Given that the defendant makes no such claim, and
    that the judge did not so instruct, the matter is not before us.
    However, it is worth noting that the judge explained to the
    juror that he (the judge) cannot instruct the juror on how to
    deliberate, and that the jury had the power to determine what
    the facts are.
    20
    defense counsel would have altered his trial strategy and
    tactics if the evidence had been timely disclosed.     The judge
    denied the motion.
    On appeal, the defendant claims that the judge abused his
    discretion by denying the request for a mistrial because the
    late disclosure of the evidence compromised his prepared
    defense, which he already had been pursuing in his opening
    statement and through cross-examination of witnesses who already
    had been dismissed.     We disagree.
    "We review the denial of a motion for a mistrial for abuse
    of discretion."    Commonwealth v. Martinez, 
    476 Mass. 186
    , 197
    (2017), citing Commonwealth v. Lao, 
    460 Mass. 12
    , 19 (2011).
    "The trial judge is in the best position to assess any potential
    prejudice and, where possible, to tailor an appropriate remedy
    short of declaring a mistrial."     Commonwealth v. 
    Martinez, supra
    .    See Commonwealth v. Amran, 
    471 Mass. 354
    , 360 (2015).

    one."     Commonwealth v. Medeiros, 
    395 Mass. 336
    , 351 (1985).
    The question, when dealing with the delayed disclosure of
    exculpatory or inculpatory evidence,14 is "whether, given a

    evidence is not significant where the issue is delayed
    disclosure, as opposed to failure to disclose." Commonwealth v.

    385 Mass. 165
    , 175 n.10 (1982).
    21
    timely disclosure, the defense would have been able to prepare
    and present its case in such a manner as to create a reasonable
    doubt that would not otherwise have existed."   Commonwealth v.
    Baldwin, 
    385 Mass. 165
    , 175 (1982), quoting from Commonwealth v.
    Wilson, 
    381 Mass. 90
    , 114 (1980).
    "Absent a showing of bad faith, we consider the primary
    issue of prejudice. In measuring prejudice, 'it is the
    consequences of the delay that matter, not the likely
    impact of the nondisclosed evidence, and we ask whether the
    prosecution's disclosure was sufficiently timely to allow
    the defendant "to make effective use of the evidence in
    preparing and presenting his case."'"15
    Commonwealth v. Stote, 
    433 Mass. 19
    , 23 (2000), quoting from
    Commonwealth v. 
    Wilson, supra
    .   See Commonwealth v. Nolin, 
    448 Mass. 207
    , 224 (2007).
    After hearing arguments on the motion for a mistrial, the
    judge took the matter under advisement and gave the defendant
    four days to digest the new evidence and to determine how he
    would proceed.16   The judge also ordered a copy of the transcript
    of defense counsel's opening statement so the judge could
    determine whether counsel had made any promises he could no
    longer keep in light of the new evidence.   When the trial
    15The parties agree that the prosecutor exercised no bad
    faith in the late disclosure of the report and the photographs.
    16The motion was made on a Thursday morning and Friday was
    a scheduled day off, so defense counsel had until Monday morning
    to review the new evidence.
    22
    resumed, the judge denied the request for a mistrial.    He held
    that counsel had made no promise he could not keep, and the
    judge ordered the Commonwealth to make the witnesses who had
    already testified available in the event that the defendant
    wished to recall them.
    There was no abuse of discretion for several reasons.       As
    the judge noted, the photographs and the diagrams in the
    eighteen-page report were neither exculpatory nor exceptionally
    probative to either party's case.   The judge even offered to
    exclude the evidence, if the defendant so chose.   Also, as the
    judge noted, although there were eighty-five crime scene
    photographs, they appeared to him to be cumulative and
    repetitive of other crime scene evidence; all were taken in the
    same general areas.
    There is no merit to the defendant's claim that the late
    disclosed evidence changed the blocking of the crime scene.      Nor
    did the new evidence depict the area as more "complicated" than
    described by the Commonwealth's witnesses in a manner that
    weakened the Commonwealth's case.   In fact, the photographs and
    the diagrams corroborated the witnesses' testimony that
    Detective Guy pulled the defendant and Peter away from each
    other and pinned the defendant up against a parked bus, and that
    the knife fell to the ground near the bus during the struggle
    between Detective Guy, the defendant, and Peter.
    23
    In view of the continuance, the delayed disclosure cannot
    be said to have forced the defense to change any tactics that
    already had been in place.    The defense was that the police
    investigation was inadequate.    See Commonwealth v. Bowden, 
    379 Mass. 472
    , 485-486 (1980).   The gravamen of the defense was that
    the police conducted a subpar investigation because they were
    biased and had chosen sides because one of the victims was an
    off-duty State trooper.   The crime scene photographs and the
    diagrams would have added little to this argument.    Also, it was
    understood by all parties that the Commonwealth would not
    introduce the photographs or any portion of the crime scene
    report.    Given the remedies applied and the lack of prejudice to
    the defendant, there was no error or abuse of discretion in the
    denial of the request for a mistrial.    See Commonwealth v.
    Costello, 
    392 Mass. 393
    , 399-400 (1984); Commonwealth v.
    Hamilton, 
    426 Mass. 67
    , 70-71 (1997).
    c.     Prosecutor's opening statement and closing argument.
    Finally, the defendant claims that the prosecutor made a series
    of improper remarks during her opening statement and closing
    argument that created a substantial risk of a miscarriage of
    justice.   We disagree.
    Opening statement.     "The proper function of an opening is
    to outline in a general way the nature of the case which the
    counsel expects to be able to prove or support by evidence."
    24
    Commonwealth v. Staines, 
    441 Mass. 521
    , 535 (2004) (citation
    omitted).     See Commonwealth v. Lodge, 
    89 Mass. App. Ct. 415
    , 417
    (2016).     Here, the defendant takes issue with the prosecutor's
    statement that "[w]e are here today because the defendant, Mr.
    Njisane Chambers, doesn't handle rejection well.     He can't let
    things go."    The prosecutor repeated this theme in other
    portions of her opening statement.17
    Contrary to the defendant's claim, when viewed in light of
    the entire opening, these statements do not amount to improper
    argument, but rather were a proper outline of the general nature
    of the case and gave context to the defendant's stabbing of the
    victims.    See Commonwealth v. Tarjick, 
    87 Mass. App. Ct. 374
    ,
    381 (2015) (prosecutor may "place in context the evidence that
    the Commonwealth reasonably expected to produce at trial").       The
    prosecutor's statements were made in the context of the
    anticipated evidence regarding Almeida's rejection of the
    defendant's advances in the club and the defendant's reaction to
    that rejection by throwing a drink as well as by attacking the
    group with a knife after they left the club.    There was no
    error, and thus no risk that justice miscarried.
    17The prosecutor told the jury that "[h]e waited. He
    waited outside as the minutes ticked by, and his anger built up
    more and more"; he "can't let things go. He doesn't handle
    rejection well"; and "his anger built up like a ticking time
    bomb."
    25
    The defendant also finds impropriety in the prosecutor's
    statement that James Feeney, who was in a band tour bus parked
    on Warrenton Street at the time of the stabbing, would testify
    "that it was the defendant, Mr. Chambers, [who] stabbed these
    three individuals in the street . . . and it was the defendant
    and the defendant alone who is responsible for these actions."
    This the defendant claims was improper because Feeney did not
    make an out-of-court identification.    We disagree.
    In general, "a prosecutor in a criminal action may state
    anything in [her] opening argument that [she] expects to be able
    to prove by evidence. . . .    This general rule also permits the
    prosecutor to state those facts which would have to be proved by
    inferences."   Commonwealth v. Smith, 
    58 Mass. App. Ct. 166
    , 175
    (2003).    Here, Feeney testified that he saw a smaller black male
    push a woman to the ground and attempt to run away before being
    tackled to the ground by a tall, muscular black male, and that
    the bigger male was on top of the smaller male when the police
    arrived.   Also, both Officer Fabiano and Detective Guy testified
    that Peter was pinning the defendant down when they arrived.
    Based on the descriptions of the scene and the defendant, the
    prosecutor's statement was a fair inference from the evidence.
    To the extent there was any misstep, the judge instructed the
    jury that opening statements are not intended to persuade them,
    26
    but only to offer an outline of what the expected evidence will
    be.   See Commonwealth v. Simpson, 
    434 Mass. 570
    , 584 (2001).
    Closing argument.   Finally, the defendant claims that the
    prosecutor argued facts not in evidence and engaged in burden
    shifting.    The defendant did not object to the prosecutor's
    closing argument and, therefore, we review for error and, if
    any, whether it created a substantial risk of a miscarriage of
    justice.    See Commonwealth v. Coutu, 
    88 Mass. App. Ct. 686
    , 697
    (2015).
    The defendant claims that the prosecutor misstated the
    evidence when she argued that "not only [Peter], but all of the
    victims gave statements.    Mercelino Amaro gave statements.    Jim
    Feeney, never met these people in his life, he gave a statement.
    And who did they all say was responsible?    The defendant."     The
    defendant offers, however, that this was false because only
    Peter and Lebrun identified the defendant.    We disagree.     The
    argument was properly based on the reasonable inferences from
    the evidence.    Amaro, Feeney, and Almeida each described the
    defendant by his physical appearance in a consistent manner,
    i.e., that he was a short, slim, black male with short hair.
    This physical description of the assailant matched the
    defendant, who Peter and Lebrun identified as the same person
    from the earlier altercation in the club.    Although Almeida,
    Feeney, and Amaro, did not directly make out-of-court or in-
    27
    court identifications of the defendant, the prosecutor properly
    suggested, based on the circumstantial evidence and reasonable
    inferences therefrom, that the person they described as the
    perpetrator was the defendant.    See Commonwealth v. Deane, 
    458 Mass. 43
    , 55-56 (2010) ("A prosecutor is entitled to argue the
    evidence and fair inferences to be drawn therefrom" [quotation
    omitted]).    There was no error and, thus, no risk that justice
    miscarried.
    The defendant also claims that the prosecutor engaged in
    impermissible burden shifting when she argued, regarding the
    deoxyribonucleic acid (DNA) evidence:    "The DNA doesn't tell us
    why, and defense counsel is only focusing on the police, the
    police failures, the DNA, because that's all he has to hang his
    hat on, because he has no reasonable explanation, no rational
    explanation for the actions of the defendant."    This, the
    defendant argues, signaled to the jury that the defendant had an
    affirmative duty to bring forth evidence of innocence.
    However, as the Commonwealth maintains, the argument should
    be understood to be a comment on the weakness of the defendant's
    case and the trial tactic of highlighting the prosecution's
    failure to test the blood on the knife for DNA.    See
    Commonwealth v. Feroli, 
    407 Mass. 405
    , 409 (1990); Commonwealth
    v. Buzzell, 
    53 Mass. App. Ct. 362
    , 367-368 (2001).    In fact, in
    the defendant's closing, in support of his Bowden defense,
    28
    counsel highlighted that because the knife had not been tested
    for DNA, it was unknown whether the knife had a mixture of DNA
    on it or whether it may have had only the defendant's DNA on it,
    and how the latter would have damaged the Commonwealth's case.
    The prosecutor was entitled to "comment on the trial tactics of
    the defence," Commonwealth v. Grimshaw, 
    412 Mass. 505
    , 507
    (1992), and to respond to the defendant's closing argument.     See
    Commonwealth v. Smith, 
    404 Mass. 1
    , 7 (1989).   See also
    Commonwealth v. 
    Feroli, supra
    ("A prosecutor is entitled to
    emphasize the strong points of the Commonwealth's case and the
    weaknesses of the defendant's case, even though he may, in so
    doing, prompt some collateral or passing reflection on the fact
    that the defendant declined to testify"); Commonwealth v. Cohen,
    
    412 Mass. 375
    , 388 (1992) ("It is . . . not improper for a
    prosecutor to comment on a defendant's attempt to confuse or
    distract the jury by diverting their attention from the strong
    evidence of the defendant's guilt").
    However, even if the prosecutor's argument was improper, we
    conclude that it did not create a substantial risk of a
    miscarriage of justice.   Several components of the case lead to
    this conclusion.   See Commonwealth v. Randolph, 
    438 Mass. 290
    ,
    297 (2002).   First, there was no objection to the statements,
    which lends credence to the belief that they did not create an
    unfair or prejudicial impact.   See Commonwealth v. Lyons, 426
    
    29 Mass. 466
    , 471 (1998).     Second, the Commonwealth's case was
    particularly strong.     The defendant was identified and detained
    at the scene of the stabbing after his attack on the victims
    with whom he had earlier fought inside the club.     Third, the
    judge instructed the jury on the limited purpose of closing
    arguments and, more importantly, that the Commonwealth bore the
    burden of proof and that "the defendant in a criminal case never
    has any duty or obligation to testify or to come forward with
    any evidence."18
    Judgments affirmed.
    18Given our resolution of the appeal, there is no need to
    address the defendant's argument relative to cumulative error.
    RUBIN, J., dissenting.     This is a straightforward case.
    Both the public and the defendant are entitled to fair and
    impartial jurors, and the requirement of fairness and
    impartiality includes the ability to attend to and fairly to
    consider the evidence and the judge's instructions.     See
    Commonwealth v. Sleeper, 
    435 Mass. 581
    , 589 (2002) ("Both the
    Commonwealth and the defendant are entitled to an attentive
    jury").   Therefore, as the Supreme Judicial Court reminded us
    during the pendency of this very appeal, "As a general
    principle, it is an abuse of discretion to empanel a juror who
    will not state unequivocally that he or she will be impartial."
    Commonwealth v. Colton, 
    477 Mass. 1
    , 17 (2017).
    Juror number (no.) twelve would not, and did not, make any
    such statement.   Indeed, the majority does not attempt to
    identify a single statement of the juror in which he said he
    could be fair and impartial.    The very closest the juror came to
    that was to say, "I would definitely do my best, but I can't
    promise anything," which, as a matter of law, does not amount to
    the required unequivocal statement.    The Supreme Judicial Court
    has already held that a juror's statement that "he would 'do
    [his] best'" is not an "unequivocal[] state[ment] that [the
    juror] would be impartial," and that it does not suffice to
    permit a juror to sit whose impartiality is in question.
    Commonwealth v. Vann Long, 
    419 Mass. 798
    , 804 (1995).     Juror no.
    2
    twelve's "I can't promise anything" addendum only weakens his
    statement.
    In fact, far from unequivocally stating that he would be
    fair and impartial, juror no. twelve stated unequivocally that
    he believed that he could not be fair and impartial in this
    matter, and never subsequently stated unequivocally that he
    could or would be fair or impartial or, indeed, that he could
    listen and attend to the evidence and the instructions.     He
    never even said that he thought he could.   It was, therefore, an
    abuse of discretion to seat him.
    During trial, both parties moved that he be discharged
    because of his statements.   Though the Commonwealth here
    attempts to defend its favorable verdict, in the trial court it
    went so far as to seek emergency interlocutory relief before the
    single justice of the Supreme Judicial Court from the refusal of
    the trial judge to discharge juror no. twelve.
    The law is clear that no one in this Commonwealth should be
    required to stand trial before a juror like this who cannot
    unequivocally say he will fairly and impartially judge the case
    before him.   Rather than identifying any purportedly unequivocal
    statement by the juror, the majority first suggests –-
    incorrectly in light of Vann Long –- that a judge has discretion
    to find a juror who says he cannot be fair or impartial
    nonetheless can be.   More fundamentally though, and more
    3
    troubling because the judge never made any such finding about
    this juror, the majority, in order to affirm the judgments,
    announces without support that where a juror cannot be fair and
    impartial because of "frustration about the inconvenience
    inherent in performing jury service," he or she may nonetheless
    be seated.   Ante at        .
    But there are no kinds of unfairness or partiality that are
    tolerable in a juror.   Because I think the judgments therefore
    should be reversed, I must respectfully dissent.
    A.   The first and second days of trial.    1.   Facts.   At the
    end of the first day of trial, juror no. twelve, an
    undergraduate student only six weeks into his freshman year at
    Northeastern University (university), sent the judge a note that
    said, "I believe that the stress of missing school will result
    in an impartial [sic] decision on my part.    I am terrified that
    I will fail my classes and do not know if I can make a fair
    decision in the near future."   This was a statement that juror
    no. twelve did not believe that he could be fair and impartial.
    At a sidebar conference, the judge encouraged the juror,
    and told him that the university would make accommodations for
    jury service.   The judge instructed the juror to speak to
    university officials about what accommodations they would make
    for him, and to report back.    The next morning, in response to
    questions from the judge that reflected the judge's clear
    4
    understanding of the issue, "Are you going to be able to give me
    attention, are you going to be able to be fair to this guy and
    this woman in their respective cases?    Are you going to be able
    to listen attentively to my instructions?    Are you going to be
    able to listen to the evidence?" juror no. twelve said only, "I
    would definitely do my best, but I can't promise anything."
    The judge did not respect that answer but said, among other
    things, "People have to step up to the plate."   The juror
    responded, "I agree that you're telling me to man up, and I
    will."
    The judge, presumably recognizing the impropriety of
    shaming the juror into giving what the juror perceived as the
    judge's desired response, immediately said, "I'm not saying man
    up.   I didn't say that."   See Commonwealth v. Auguste, 
    414 Mass. 51
    , 58 (1992) (judge may probe impartiality with questions, but
    may not seat juror on basis of "answers suggested or, in fact,
    required by the questions. . . .    Jurors should not be coerced
    into a particular response").   The judge then told juror no.
    twelve, "[Y]ou're almost a perfect candidate for being able to
    use your analytical skills to be able to listen to the evidence
    and . . . factor in . . . where the evidence lead[s] you to
    . . . .   You're a perfect candidate to be able to help out the
    Commonwealth and the defendant to make sure that their result is
    reached."   The juror responded, "I simply don't know."
    5
    The defendant moved to discharge the juror, and his motion
    was denied.    Although the Commonwealth did not move at this
    point to discharge the juror, it did at the end of trial in part
    "based on what he said from Day 1 that he couldn't be impartial
    after the opening statements and hearing from the first
    witness."     Indeed, the Commonwealth sought emergency
    interlocutory relief in the Supreme Judicial Court from the
    order denying this motion.
    2.   Analysis.    "As a general principle, it is an abuse of
    discretion to empanel a juror who will not state unequivocally
    that he or she will be impartial."     
    Colton, 477 Mass. at 17
    .    As
    these facts describe, juror no. twelve stated unequivocally that
    he believed that the stress of missing school would render him
    partial, and that terror at the prospect of failing his classes
    would compromise his ability to be fair.    In response to the
    judge's questions, this juror would not state unequivocally that
    he could be fair or impartial or that he could be attentive and
    listen to the evidence and the judge's instructions.      He did not
    even say that he thought he could.    His strongest statement, "I
    would definitely do my best, but I can't promise anything," is
    inadequate.    In Vann 
    Long, 419 Mass. at 804
    , the Supreme
    Judicial Court held that as a matter of law, "[I will] do [my]
    best" is not the requisite "unequivocal[] state[ment] that [the
    juror] would be impartial."     Consequently, it cannot suffice to
    6
    permit a juror to sit whose impartiality is in question.     
    Ibid. See Commonwealth v.
    Prunty, 
    462 Mass. 295
    , 312 (2012).     The
    cases put forward by the majority in which no abuse of
    discretion was found in seating a juror who put forth some
    version of "I think I could," are therefore irrelevant.     Ante
    at        .
    Nor is Prunty, the first case cited in the majority list,
    ante at       , which the majority describes as finding "no
    abuse of discretion to retain African-American juror who stated
    he 'would be able to do my best' to not let defendant's racial
    prejudice affect juror's ability to be impartial," of any
    relevance here.   As the court there explained, Prunty did not
    alter the rule articulated in Vann Long that a statement that "I
    will do my best" is an insufficiently unequivocal statement of
    an ability to be fair and impartial.   Prunty, supra at 311-312.
    The statement in Prunty was made by an African-American juror
    who had already expressed unequivocally that he could be
    impartial and with respect to whom there was no reason to
    question whether he could be fair and impartial.   
    Ibid. The juror made
    the statement when called back for further voir dire
    after defense counsel, whose client had made several highly
    offensive racist comments that were expected to be introduced at
    trial, attempted to utilize a peremptory challenge to strike the
    juror and the judge concluded that a prima facie showing had
    7
    been made that it was based on the juror's race.    
    Ibid. Defense counsel then
    alleged without any basis that his client's
    comments "certainly are going to perhaps get under the skin of
    somebody who might be a little bit more sensitive to that issue,
    particularly where that is their descent."    
    Id. at 300.
          There
    was no evidence that the juror harbored any racial prejudice
    and, as the court explained, the rule of Vann Long was not
    applicable in that circumstance because, since "no . . . bias
    was apparent, . . . an unequivocal response was not necessary to
    rehabilitate the juror's impartiality."    
    Id. at 312.
        By
    contrast, of course, it is applicable here, where there was
    reason to believe the juror could not stand indifferent based on
    the juror's explicit statement that he could not be fair or
    impartial.
    Consistent with case law, when the defendant moved at the
    end of the colloquy for the juror's discharge he should have
    been excused for cause.    That should have been the end of this
    case.   No one would want this juror sitting on his or her own
    case, and the defendant was not required to have him sitting on
    his.
    In support of its conclusion to the contrary, the
    majority's most fundamental conclusion is that the juror's
    concerns "centered on his frustration about the inconvenience
    inherent in performing jury service.    It did not reflect
    8
    partiality or bias such that retaining him constituted
    reversible error."   Ante at        .   Thus even if the judge
    "credited" the juror's statement that his "scholastic concerns"
    made it impossible for him to be fair and impartial, this was
    "not a basis to discharge [the] juror."     Ante at       .
    This is meritless.    The law is clear that jurors must
    fairly, impartially, and attentively consider the evidence
    before them and the judge's instructions.    See, e.g.,
    Commonwealth v. Dickerson, 
    372 Mass. 783
    , 794 (1977) ("only
    jurors who will fairly and attentively consider the evidence
    before them" may be seated).   The majority concedes as much.
    See ante at          ("When evaluating juror impartiality," judges
    must among other things inquire whether potential jurors can
    "properly weigh the evidence, and follow the judge's
    instructions").   That juror no. twelve's inability to fairly and
    impartially attend to the evidence and the judge's instructions
    arose from the burdens the juror concluded were put on his
    studies by jury service obviously does not render his service
    proper.
    To the extent the majority by this language means
    otherwise, i.e., that there are some jurors who cannot be fair
    or impartial who may nonetheless sit, the case they cite of
    course does not support that proposition.    Commonwealth v.
    Campbell, 
    51 Mass. App. Ct. 479
    (2001), rather, held correctly
    9
    that "[a] juror's complaints about the length of the
    proceedings, or expressions of frustration about having to serve
    as a juror, do not necessarily reflect the juror's inability to
    perform his or her function as an impartial trier of fact."        
    Id. at 483-484.
      The court there made clear that, unlike in the
    instant case, "[t]here was no indication that the juror's
    complaints . . . reflected an inability to perform his function
    as an impartial trier of fact."   
    Id. at 484.
    By contrast, in this case that inability is precisely what
    the juror asserted.   The juror's statements were not merely
    understandable complaints or expressions of frustration,
    something that, the majority tells us, need not be taken "as an
    indicator of partiality."    Ante at        .   They were actual
    statements by a juror who believed that he could not be fair and
    impartial.    As the rule requiring an unequivocal statement from
    a juror that he or she will be fair and impartial makes clear,
    there is no variety of unfairness or partiality that is
    tolerable in a juror, and holding otherwise, as the majority
    appears to do here, contravenes centuries of precedent to the
    contrary:    "[W]here there is abundant latitude for selection [of
    jurors,] none should sit who are not entirely impartial.    This
    is equally demanded by the general principles of the common law,
    (Hesketh v. Braddock, 3 Burr. 1856,) and by those of our own
    constitution, requiring all judges to be as free, impartial and
    10
    independent as the lot of humanity will admit.     Declaration of
    Rights, art. 29."     (Emphasis supplied.)   Davis v. Allen, 
    11 Pick. 466
    , 467-468 (1831) (Shaw, C.J., for a unanimous court).
    If instead the majority means only to say that the juror
    was, in fact, merely frustrated, and did not actually mean that
    he could not be fair and impartial, such a finding of fact -–
    one never made by the trial judge (notwithstanding the
    majority's suggestions), and which cannot be made properly by an
    appellate court on appeal -– is foreclosed in this case by the
    case law that allows a finding that a juror will be fair and
    impartial only where a juror states unequivocally that he or she
    will be impartial.1    Put another way, the law mandates a
    particular method for determining whether jurors can be fair and
    impartial, a method designed to make sure no unfair or partial
    juror sits:   the judge is required to ask them if they can be,
    and to take them at their word.    This is precisely why, "[a]s a
    1 The majority goes so far as to assert that the judge
    "credited the juror's statements as being unequivocal," ante
    at       . The transcript shows that the judge made no finding
    that the statements were unequivocal nor, as the text makes
    clear, could he. Nor did the judge's hastily prepared findings,
    made in writing during the brief pendency of the Commonwealth's
    own interlocutory appeal from the judge's denial of its motion
    to discharge the juror, say there was an unequivocal statement
    by the juror that he could be fair and impartial. Indeed, they
    do not, and could not, say even that the juror said he could be
    fair or impartial.
    11
    general principle, it is an abuse of discretion to empanel a
    juror who will not state unequivocally that he or she will be
    impartial."   
    Colton, 477 Mass. at 17
    .2
    The majority also holds that "the judge could properly
    conclude that he had allayed the juror's school work concerns,"
    ante at         , without any citation to the record of what the
    juror actually said.   Here is what the juror said:   After the
    juror confirmed that he had contacted university officials and
    that they had told him that they would "work with [him]," the
    judge asked, "Are you going to be able to be fair to this guy
    and this woman in their respective cases?   Are you going to be
    able to listen attentively to my instructions?   Are you going to
    be able to listen to the evidence?"   The juror responded, "I
    2  The majority asserts that I am advancing a "'rule' . . .
    without support," ante at        . But the text 
    quoted supra
    is
    contained in the Supreme Judicial Court opinion in Colton, which
    I cite. Quarreling essentially with that decision, the majority
    says that the rule "would strip the judge of any discretion to
    assess a juror's credibility and would relegate our appellate
    role to simply determining whether all of the 'magic words' had
    been spoken in the colloquy." Ante at         .
    Determining whether someone said something
    unequivocally does not involve a credibility determination, nor
    does requiring an unequivocal answer to one question mean that a
    colloquy is nothing more than a series of required words.
    Finally, no "magic" words must be spoken. Just some version of
    the word "yes" –- even, "Yes, I think so," may suffice, see
    
    Colton, supra
    -- something the juror here, even under pressure
    from the judge to "step up to the plate," indeed, even after
    agreeing to sit, could never bring himself to say.
    12
    would definitely do my best, but I can't promise anything,"
    words that, as 
    described supra
    , as a matter of law, cannot
    suffice to show that a juror whose impartiality is in question
    can stand fair and impartial.    See Vann 
    Long, 419 Mass. at 804
    .
    Concluding that the juror's response meant that the juror's
    concerns were not allayed -– which is what the words mean -– the
    judge immediately asked him what would "interfere with" his
    ability to exercise these three essential functions, and the
    juror responded, "Just fear of, just completely falling behind
    and failing my classes and just all the stress of everything."
    The judge responded, "But I thought that the [university] was
    going to give you a little bit of an antidote, maybe not enough"
    (emphasis supplied).   The juror then agreed with the judge that
    what the school would give him was not enough:    "They will give
    a little more time, but that still means doing double the work
    in the same amount of time."    The only other statements the
    juror made on the subject were, "I agree that you're telling me
    to man up, and I will," which the judge told the juror was
    somehow a misinterpretation of what he (the judge) had said,
    and, "I simply don't know," in response to the suggestion that
    he would be "a perfect candidate" to listen to the evidence and
    to deliberate on the case.   Not one of the juror's statements
    even hints at the possibility that the judge had allayed his
    concerns.
    13
    The other reasons given by the majority for refusing to
    take the juror at his word are insubstantial.    Stating that he
    could not be fair and impartial could not have been a "habit[]
    of speech" that did not mean that the juror could not be fair
    and impartial.   See ante at       .     Indeed, the case in which
    the "habit[] of speech" language appears was one in which the
    court concluded that a juror who said he "would really hope"
    that he could be fair was not utilizing a mere habit of speech,
    but was asserting that he could not assure the judge that he
    could be impartial.   Vann 
    Long, supra
    .    Today is the first time
    either of our appellate courts has held that the words of
    someone who did not unequivocally state that he could be fair
    and impartial might merely have been a habit of speech.     Yet no
    halfway competent English speaker would habitually use the
    phrases, "I believe that the stress of missing school will
    result in [a partial] decision on my part," "I am terrified that
    I will fail my classes and do not know if I can make a fair
    decision in the future," or "I can't promise anything," with
    respect to fairness to the parties or ability to listen to the
    evidence or the instructions, to mean, "I can be fair and
    impartial."
    Nor, of course, is it particularly impressive -– though the
    majority finds it "notabl[e]," ante at           –- that the juror
    "never again raised his concerns," when he had already twice
    14
    done so only to be told by the presiding judge, on the bench and
    in a robe, to "step up to the plate."   And while, doubtless,
    "the judge was uniquely situated to measure juror no. twelve's
    demeanor and credibility," ante at         , the judge never
    suggested that juror no. twelve was not credible or that his
    concerns should not be taken at face value.   Because the juror
    would not state unequivocally that he would be fair and
    impartial, indeed because he would not even say that he thought
    he could be -– even as he agreed to sit because the judge told
    him to "step up to the plate" -– there is no basis in the record
    for a finding that he would.   And no amount of meaningful gazing
    by a judicial officer into this juror's eyes could render his
    statements unequivocal expressions of an ability to be fair and
    impartial.
    At the end of the day, there is not a single statement in
    the record, and the majority does not purport to point to one,
    in which juror no. twelve in fact said that he could be fair and
    impartial.   This is all that is needed to decide the case and on
    this basis alone I would reverse.
    But of course there is on this record much more.   Because
    after the jury had been instructed, but before deliberations
    began, this selfsame juror sent another note to the judge, this
    one stating, "I believe I may know information that would affect
    15
    my ability to judge the case based solely on the information
    received in the trial."
    B.   After the jury were instructed.    1.   Facts.   Called to
    sidebar after sending the note just described, juror no. twelve
    said, "I heard about how the jury actually has more power than
    you expressed, that they can judge not only based on just
    information, but whether they believe the law is fair, or their
    personal convictions . . . to judge guilty or not guilty."
    The judge explained that what the juror had heard about was
    jury nullification.   The judge said, "That is not permitted.
    That is definitely not permitted . . . ."    Nonetheless, the
    juror still hesitated when the judge asked, "Is there any
    question of your ability to be able to take the law as I gave it
    to you, and apply it to the facts as you and your other jurors
    find them?"
    The judge decided therefore to go through the law on which
    the entire jury had been instructed, element by element, asking
    this one juror whether he had any difficulty understanding that
    law and applying it to the facts as he found them.    When the
    judge reached the point of explaining the elements of possession
    of a weapon, and in particular that knives with certain kinds of
    casements, when one-and-one-half-inches in length or longer, are
    defined as dangerous weapons, he asked, "Do you have any problem
    with taking the law as I give it to you, the statute that I gave
    16
    you, and applying it to the facts as you might find them?" and
    juror no. twelve said, "I don't believe that the law should be
    that a knife of that size should be a dangerous weapon, but I
    guess . . . ."
    The judge then said, "Well, you know what you get to do
    with that, and I'm not being facetious, you get to call up your
    legislator and you get to ask him to change the law, but that's
    the law as it is right now."   The judge then went on to quarrel
    with the juror's understanding of the law on which he had now
    twice been instructed, saying, "It's not one-and-a-half inches,
    it's with that casement . . . ."     When finally asked again, "Do
    you have any problem applying that law?" the most the juror
    would muster was, "I guess not."
    Still, the judge did not dismiss the juror.     But,
    correctly, the judge did say, "I guess not is not good enough
    for me because it's something that you may disagree with."      He
    then went on, "You have every right.     I disagree, we all
    disagree with some of the laws as it relates to some of the
    things that are prohibited by our government. . . .     But that's
    what the law is, and as a juror, regardless of your personal
    beliefs you have to apply the law.     Will you be able to do
    that?"
    Having thus been told that "yes" was the only answer that
    the judge would accept -– "I guess not is not good enough," the
    17
    judge said -– the juror did not even then say yes.   He responded
    again, "Well I thought that the jury had the power to choose
    whatever way to . . . ."   The judge interrupted the juror and
    said, "I just told you it doesn't," which is incorrect as a
    matter of law, see Commonwealth v. Hebert, 
    379 Mass. 752
    , 755
    (1980) ("[I]t remains within the power of a juror to vote his or
    her conscience").   The juror responded, "So, there's a legal
    punishment if the jury does not . . . ."
    He was cut off by the judge, who misunderstood the juror's
    statement, thinking that he was addressing punishment of the
    defendant when, as the record reflects, the juror meant that he
    misunderstood the judge to have told him –- what is also
    incorrect –- that he (the juror) would be punished by law if he
    engaged in jury nullification.3
    3 I note that, while courts have long held that jurors
    should not be instructed that they have the power to nullify, no
    court of which I am aware has ever approved an instruction -–
    erroneous as a matter of law -– that the jury lacks this power.
    See 
    Hebert, supra
    ("[I]t remains within the power of a juror to
    vote his or her conscience"); Commonwealth v. Floyd P., 
    415 Mass. 826
    , 832 n.6 (1993) ("Cases acknowledge that, while it is
    improper for a jury to take such action, in practice they have
    the power to accomplish such a result"). While the judge
    therefore should not instruct a juror that he or she has the
    power of nullification, it also cannot be permissible to
    instruct a juror falsely that he or she lacks the power to vote
    his or her conscience, or to leave an impression that there is
    some punishment that may be associated with doing so. The
    majority does not even attempt to justify the judge's erroneous
    instruction, and claims only that "the matter is not before us."
    Ante at        . But the defendant argued on appeal that "it
    18
    At this point, unsurprisingly, the defendant requested
    again that the juror be discharged and, equally unsurprisingly,
    the Commonwealth joined in that motion.
    2.   Analysis.   Although of course the Commonwealth here
    argues in support of the verdict, at trial the prosecutor joined
    in the motion to discharge the juror based "on what [juror no.
    twelve] said from Day 1 that he couldn't be impartial after the
    opening statements and hearing from the first witness, and the
    fact that again now he's saying he doesn't believe that the law
    --."    The judge denied the motion.   (And, less than two hours
    later the prosecutor informed the judge that she had filed a
    motion under G. L. c. 211, § 3, to the single justice of the
    Supreme Judicial Court on an emergency basis to stay
    proceedings, and appealing the refusal to discharge juror no.
    twelve, a request that, given its interlocutory posture, the
    single justice unsurprisingly denied.)     Having failed to
    persuade the judge, the Commonwealth is not technically
    judicially estopped from defending the seating of the juror
    here, see Otis v. Arbella Mut. Ins. Co., 
    443 Mass. 634
    , 644
    (2005) (judicial estoppel precludes party from "asserting a
    remains within the power of a juror to vote his or her
    conscience," quoting from 
    Hebert, supra
    , and that "the judge did
    not so instruct this juror." Although I do not believe we need
    to reach the issue, this does suffice to raise it.
    19
    position inconsistent with a position previously and
    successfully asserted" [emphasis supplied]), but its postverdict
    defense of the seating of the juror rings particularly hollow in
    light of its strenuous challenge to the juror at the time of
    trial.
    By the time of the joint motion to excuse the juror, he had
    repeatedly stated an inability or an unwillingness to apply the
    law as given, and he should have been excused for cause.
    Indeed, there can be little doubt that the judge's lengthy and
    repeated statements to the juror -– including both a refusal to
    accept an answer that the juror could not follow the law, and
    leaving the juror with the incorrect impression that he could be
    punished for voting his conscience -– may well have "affect[ed]
    the juror's judgment."   
    Hebert, 379 Mass. at 755
    (judge's
    "coercive" interaction with juror, where juror believed that
    Commonwealth had proved each element of crime beyond reasonable
    doubt but could not in good conscience convict, was improper);

    questions").4   For this independent reason, the juror should have
    4 The majority is of course correct that the judge did not
    tell the juror that he would be punished for engaging in jury
    nullification, but this does not change the fact that the juror
    clearly, and incorrectly, believed that he could be punished.

    been dismissed.   And even if either his statements on the first
    and second days of trial, or his statements after the jury were
    instructed, alone would not have warranted it, certainly taken
    together they required his dismissal.
    Although I appreciate that trial judges sometimes may have
    a difficult task in ensuring that jurors do not impermissibly
    avoid their obligation to serve, and while the judge's decision
    not to dismiss juror no. twelve appears to have been at least
    partially motivated by the desire to avoid a mistrial,5 as both
    that the judge is less blameworthy for neglecting to correct the
    juror's obvious misconception than he would have been for
    creating it –- is plainly wrong. See ante at         . Our
    question is whether the defendant received a fair trial, and the
    fact is that a citizen entered the jury room believing falsely
    that he could be punished for voting his conscience.
    5 After his colloquy with juror no. twelve on the second day
    of trial, the judge stated, "I'm going to keep it as a work in
    progress. He's not going to be a juror that is going to
    deliberate if he's impaired. I'm with you on that part of it,
    and I think I may do a little inquiry as to the detail of this
    letter, and I think I did a splendid job of trying to salvage
    this so you don't mistry the case . . . ." Also, after learning
    that the defendant and the Commonwealth were seeking relief from
    the single justice of the Supreme Judicial Court, he (the judge)
    requested that a court room clerk transmit certain statements to
    the clerk of the Supreme Judicial Court, including that, "The
    jury has been reduced to thirteen, and one of the jurors
    received a commitment from this Court that they would [be]
    released from duty to complete travel plans, and it is likely
    that a mistrial will occur. Further, there are factual
    misstatements in the petition that can be addressed by a
    transcript which this Court has ordered, and at the present time
    this trial judge, having had the ability to inquire of the
    challenged juror is satisfied that he ought not to be
    discharged, period." The inconvenience to either party or to
    21
    parties recognized below, he pushed too hard in this case, and
    impermissibly failed to excuse juror no. twelve for cause.
    For these reasons, it seems to me that a reversal of the
    judgments is required.   I therefore respectfully dissent.
    the judge of declaring a mistrial of course properly has no
    bearing on the question whether a juror stands fair and
    impartial.
