    COMMONWEALTH   vs.   SHAMIA WHITFIELD.
    Suffolk.    March 6, 2023. - May 19, 2023.

    Civil action commenced in the Supreme Judicial Court for
    the county of Suffolk on August 31, 2022.
    The case was reported by Wendlandt, J.
    Kathryn Sherman, Assistant District Attorney, for the
    Commonwealth.
    John P. Warren for the respondent.
    Luke Ryan, Molly Ryan Strehorn, & Joshua M. Daniels, for
    Massachusetts Association of Criminal Defense Lawyers, amicus
    curiae, submitted a brief.
    GEORGES, J.    This matter is before us on a reservation and
    report by a single justice of the Commonwealth's petition for
    2
    relief pursuant to G. L. c. 211, § 3.1    The Commonwealth
    challenges a Boston Municipal Court judge's order allowing the
    defendant's motion for discovery and requiring the Commonwealth
    to disclose significant, albeit redacted, information about a
    confidential informant (informant).2   The Commonwealth relied on
    information from the informant to obtain a search warrant that
    led to the seizure of firearms from the defendant's apartment,
    as well as the defendant's arrest on charges of unlicensed
    possession of firearms and ammunition.    The Commonwealth
    maintains that the information ordered to be disclosed is
    protected under the confidential informant privilege.    See
    Commonwealth v. Bonnett, 
    472 Mass. 827
    , 847 (2015), S.C., 
    482 Mass. 838
     (2019), citing Roviaro v. United States, 
    353 U.S. 53
    ,
    60 (1957); Mass. G. Evid. § 509 (2019).
    We conclude that, if disclosed, the information requested
    in the defendant's motion for discovery would, in effect, reveal
    the informant's identity.   In addition, the defendant does not
    dispute that disclosure of the informant's identity would give
    1 Although the Commonwealth commenced this action by filing
    a petition in the county court, for convenience we refer to the
    respondent as the "defendant."
    2 This case is one of two that we decide today involving a
    petition for relief pursuant to G. L. c. 211, § 3, concerning
    the potential disclosure of information that has been asserted
    as protected by the informant privilege. See Commonwealth v.
    Gandia, 492 Mass.     (2023).
    3
    rise to a concern for the informant's safety.     Accordingly, the
    Commonwealth's invocation of the informant privilege was proper,
    and the burden shifted to the defendant to show that the
    requested information was material and relevant to her defense.
    See Bonnett, 
    472 Mass. at 847
    .     We further hold that the
    defendant failed to make the required showing here; accordingly,
    the motion judge abused her discretion in allowing the
    defendant's motion for disclosure.3    The case is remanded to the
    county court for entry of a judgment reversing the order
    allowing the defendant's motion for discovery and remanding the
    matter for further proceedings consistent with this opinion.4
    1.    Background.   We summarize the facts as found by the
    motion judge, supplemented with undisputed facts from the
    record.5   See, e.g., Commonwealth v. Johnson, 
    481 Mass. 710
    , 712,
    cert. denied, 
    140 S. Ct. 247 (2019)
    .     On April 16, 2019,
    3 The defendant conceded at oral argument that, if this
    court determined that the Commonwealth properly invoked the
    informant privilege and that the standard set forth in
    Commonwealth v. Bonnett, 
    472 Mass. 827
    , 846-848 (2015), S.C.,
    
    482 Mass. 838
     (2019), applied to the defendant's discovery
    motion, the defendant had failed to meet her burden under that
    standard. For the reasons discussed infra, we would reach the
    same conclusion with or without the defendant's concession.
    4 We acknowledge the amicus brief of the Massachusetts
    Association of Criminal Defense Lawyers.
    5 The defendant's motion, with the assent of the
    Commonwealth, to expand the record to include the transcripts of
    eight hearings that took place in the Boston Municipal Court, is
    allowed.
    4
    Detective Brian Ball of the Boston police department (BPD),
    acting on information provided by a "carded"6 informant, filed an
    application for a search warrant, with a supporting affidavit,
    to search the defendant's person and her home for firearms.     The
    informant had told Ball and BPD Detective John Burrows that,
    within the previous thirty days, the informant had seen the
    defendant in possession of two black rifles on multiple
    occasions.   One of the rifles was an AK-47-style weapon with a
    wooden stock and curved, "banana" feeding device, and the other
    was described as long with a straight feeding device.     The
    informant had seen the weapons at the defendant's house and had
    observed them being loaded and unloaded with live ammunition.
    The informant identified the defendant from a photograph.7
    6 A "carded" informant is one whose identity is known to
    commanding officers and whose cooperation with law enforcement
    has been approved. BPD's use of informants is governed by rule
    333 of the BPD Rules and Procedures. This rule requires BPD to
    keep certain records on each confidential informant, including
    payment receipts, debriefing reports, confidential informant
    cards, photographs, informant working agreements, and criminal
    history checks of the informant. With the exception of the
    confidential informant card and the informant working agreement,
    all other BPD records concerning a confidential informant must
    refer to the informant only by a code substituted for the
    informant's name. Boston Police Department Rules and
    Procedures, Rule 333: Confidential Informant Procedures (Mar.
    1, 2006).
    7 The photograph is described in Ball's affidavit as a
    "sanitized booking photo[graph]." The record before us does not
    indicate exactly which measures were taken to "sanitize" the
    photograph at issue here. However, we note that the term
    5
    The warrant affidavit also included some information about
    the informant's reliability.    Ball averred that, on at least
    three prior occasions, the informant had provided reliable
    information to the BPD that had led to numerous arrests for
    firearms and drug violations.    Examples of these arrests were
    included in the warrant affidavit.    The informant also had
    informed police of the location of an individual who was wanted
    on a default warrant, leading to that individual's arrest.       In
    addition, the informant had conducted controlled purchases of
    drugs, which led to the seizure of drugs and firearms.    Ball
    averred that the informant has maintained regular and prompt
    contact with investigators during multiple BPD investigations.
    In describing the informant's prior involvement in BPD
    investigations, Ball purposefully omitted certain information to
    protect the identity of the informant.    Specifically, Ball
    omitted the precise dates of the investigations and the
    identities of those arrested, as well as the seizures that the
    informant's information had produced.    Ball stated that the
    defendant, who was then under BPD investigation, might know one
    or more "individuals who have come into contact with" the
    informant as a result of the informant's cooperation with BPD.
    "sanitized," when used in these contexts, indicates that
    information identifying the photograph as a booking photograph
    has been removed. See Commonwealth v. Cruz, 
    445 Mass. 589
    , 594
    (2005).
    6
    The informant requested anonymity due to safety concerns.     Ball
    averred that disclosure of the informant's identity "would pose
    an undue risk to [the informant's] safety" and would place the
    informant in "imminent danger of bodily harm or death."    Ball
    also averred that such disclosure would harm the BPD's
    reputation for protecting informants and, thus, would hinder the
    BPD's investigations and its ability to recruit cooperators.       An
    assistant clerk of the Boston Municipal Court issued the warrant
    on April 16, 2019.
    BPD officers executed the search warrant on April 22, 2019.
    After advising the defendant of the Miranda warnings, officers
    inquired whether there were any firearms in the house.     The
    defendant responded that the guns were under her bed and a crib
    in her bedroom.   Officers recovered a Model 9 rifle and a
    twelve-gauge shotgun from the bedroom, and loose ammunition and
    shotgun shells from several locations in the apartment.8     The
    defendant was arrested and charged with two counts of possession
    of a firearm without a firearm identification (FID) card, G. L.
    c. 269, § 10 (h), and one count of possession of ammunition
    without an FID card, G. L. c. 269, § 10 (h).
    Citing Mass. R. Crim. P. 14 (a) (1) (C), as appearing in
    
    442 Mass. 1518
     (2004), and Mass. R. Crim. P. 17, 
    378 Mass. 885
    8 At the time of the warrant's execution, no one present in
    the apartment was licensed to possess firearms or ammunition.
    7
    (1979), the defendant filed a motion seeking discovery of
    "rewards and promises" offered to the informant, and documents
    and information related to the informant's participation in
    other criminal investigations.     Specifically, the defendant
    requested "all documents" held by the BPD involving its
    recruitment of the informant and its work with the informant on
    any prior occasion, including debriefing reports.     These
    included any documents regarding whether the informant was paid
    or made agreements with any law enforcement agency, and any
    related documentation.   The defendant also requested a "complete
    history" of the informant's involvement with "any law
    enforcement agency," including case names, docket numbers, and
    the outcomes of those cases.     In addition, the defendant sought
    disclosure of the dates of warrants to which the informant had
    contributed, and copies of any police reports that pertained to
    the informant.
    The defendant argued that the requested information was
    necessary because the warrant lacked indicia of the informant's
    reliability, credibility, and veracity.     See Commonwealth v.
    Amral, 
    407 Mass. 511
    , 520 (1990), citing Franks v. Delaware, 
    438 U.S. 154
    , 155-156 (1978) (establishing defendant's entitlement
    to in camera hearing where defendant asserts facts that cast
    doubt on veracity of material representations in warrant
    affidavit concerning reliability of confidential informant).
    8
    The defendant specifically did not request the identity of the
    informant, positing further that "the requested information
    should in no way reveal the identity of the informant."      The
    Commonwealth filed an opposition, arguing that the requested
    information was protected by the informant privilege, see
    Commonwealth v. Dias, 
    451 Mass. 463
    , 468 (2008), and that its
    disclosure effectively would identify the informant.
    At a nonevidentiary hearing on the defendant's motion, the
    prosecutor offered to provide the defendant with receipts of any
    monetary transactions between the BPD and the informant.      The
    prosecutor asserted, however, that the Commonwealth was not
    obligated to disclose the requested information if there were a
    "safety concern."   He also observed that, to overcome the
    privilege, the defendant bore the burden of showing that the
    information was material and relevant, and necessary to the
    administration of a fair trial.   Defense counsel maintained that
    the information sought in the discovery motion corresponded with
    the information that the BPD was required to retain as part of
    its collaboration with any informant and offered to sign a
    protective order.   He also observed that he believed the motion
    was appropriate, given the difficulty defendants confront in
    prevailing on motions to suppress.
    The judge subsequently issued written findings of fact and
    a decision allowing the motion in full.   In the decision, the
    9
    judge recognized that, "[a]ssuming that the Commonwealth has
    asserted the informer's privilege, the defendant must first make
    a showing that the discovery sought is both 'material and
    relevant.'"   The judge then concluded that the information the
    defendant sought was "relevant and material to the issue of
    probable cause" and was "essential" for defense counsel's
    "preparation for a zealous defense . . . regarding his client's
    anticipated [m]otion to [s]uppress."   See Amral, 
    407 Mass. at 518
    .
    The factual findings on which the judge's decision was
    based included the following:   (1) "[t]he application for [the]
    search warrant contained no particularity about [the
    informant's] track record"; and (2) "[d]isclosure of BPD Rule
    333 information, via code number, will not reveal the true
    identity of [the informant]."   With these factual findings in
    mind, the judge reasoned that the Commonwealth's offer to
    disclose records of payments received by the informant was "not
    sufficient to test the veracity of the affidavit and/or the
    reliability of [the informant]."   The judge concluded that
    because disclosure of the information requested, using the
    informant's code number, would not reveal the informant's
    identity, such disclosure properly balanced the informant's
    safety with the defendant's rights to due process and to a
    zealous defense.
    10
    The Commonwealth moved for reconsideration.     A decision on
    that motion was delayed for approximately one year, due to
    scheduling issues resulting from the COVID-19 pandemic; the
    Commonwealth subsequently filed a motion for a decision on its
    motion for reconsideration.   In response to the Commonwealth's
    request for a decision, the judge ordered defense counsel to
    submit an affidavit in support of the defendant's original
    motion for discovery.   In the ordered affidavit, defense counsel
    averred that, inter alia, "[t]he search warrant affidavit does
    not contain any information regarding [the informant]'s track
    record or anything that could indicate the veracity of [the
    informant]," and "[c]ounsel needs this information to prepare
    for trial."
    At a subsequent nonevidentiary hearing, the prosecutor
    argued that defense counsel's affidavit did not satisfy the
    "high standard" to establish that the requested information was
    relevant and material to the defense, and essential to a fair
    determination of the case.    When the judge commented that the
    prosecutor had provided "no information" about the informant's
    reliability, the prosecutor responded that the defendant was not
    permitted to attack the reliability of the informant through a
    discovery motion and had to file a motion to suppress in order
    to do so.   The judge denied the motion for reconsideration,
    ordered the Commonwealth to produce all ordered discovery by no
    11
    later than September 2, 2022, two weeks from the date of the
    hearing, and ordered that a show cause hearing be held if the
    discovery were not produced by that date.
    On August 31, 2022, the Commonwealth filed a petition for
    extraordinary relief in the county court pursuant to G. L.
    c. 211, § 3.   A single justice then stayed the discovery
    deadline and reserved and reported the matter to this court.9
    2.   Discussion.   a.   Standard of review.   We review a
    decision on a motion for disclosure of information subject to
    the Commonwealth's assertion of the informant's privilege for an
    abuse of discretion.    See Commonwealth v. D.M., 
    480 Mass. 1004
    ,
    1006 (2018).   Where, as here, the motion judge conducted a
    nonevidentiary hearing, and the record before the judge
    consisted only of documentary evidence, such as the warrant
    affidavit, "'we are in the same position as the motion judge' to
    9 Where the single justice has exercised her discretion to
    reserve and report the matter, we proceed to adjudicate the
    merits. See Martin v. Commonwealth, 
    451 Mass. 113
    , 119 (2008).
    However, we reiterate that neither this court nor a single
    justice thereof "is required to review, pursuant to G. L.
    c. 211, § 3, the substantive merits of every confidential
    disclosure order." Commonwealth v. D.M., 
    480 Mass. 1004
    , 1004
    n.2 (2018). "To the contrary, disclosure of information
    relating to confidential informants and witnesses does not in
    and of itself constitute exceptional circumstances" warranting
    exercise of this court's extraordinary power of superintendence.
    
    Id.
     No party, including the Commonwealth, should expect this
    court to exercise its extraordinary powers of general
    superintendence lightly. See Commonwealth v. Richardson, 
    454 Mass. 1005
    , 1005-1006 (2009), citing Commonwealth v. Narea, 
    454 Mass. 1003
    , 1004 n.1 (2009).
    12
    assess the documentary evidence put forward by the parties."
    Johnson, 
    481 Mass. at 715
    , quoting Commonwealth v. Monroe, 
    472 Mass. 461
    , 464 (2015).     See Commonwealth v. Tremblay, 
    480 Mass. 645
    , 654-655 (2018) ("We now affirm the principle that an
    appellate court may independently review documentary evidence,
    and that lower court findings drawn from such evidence are not
    entitled to deference").
    "An appellate court's review of a [motion] judge's decision
    for abuse of discretion must give great deference to the judge's
    exercise of discretion; it is plainly not an abuse of discretion
    simply because a reviewing court would have reached a different
    result."   Vazquez Diaz v. Commonwealth, 
    487 Mass. 336
    , 344
    (2021), quoting L.L. v. Commonwealth, 
    470 Mass. 169
    , 185 n.27
    (2014).    Concluding that there was an abuse of discretion does
    not equate to a finding that "the judge was not conscientious
    or, for that matter, not intelligent or honest."     Vazquez Diaz,
    supra at 345, quoting L.L., 
    supra.
         Rather, "a judge's
    discretionary decision constitutes an abuse of discretion where
    we conclude the judge made a clear error of judgment in weighing
    the factors relevant to the decision, such that the decision
    falls outside the range of reasonable alternatives."        Vazquez
    Diaz, supra, quoting L.L., 
    supra.
    b.     Informant privilege.   "The government's privilege not
    to disclose the identity of an informant has long been
    13
    recognized in this Commonwealth."    Bonnett, 
    472 Mass. at 846
    ,
    quoting Dias, 
    451 Mass. at 468
    .    See Mass. G. Evid. § 509.   The
    privilege is meant to "encourage 'every citizen' in his [or her]
    'duty . . . to communicate to [the] government any information
    which [the citizen] has of the commission of an offense against
    its laws."   Commonwealth v. Swenson, 
    368 Mass. 268
    , 276 (1975),
    quoting Worthington v. Scribner, 
    109 Mass. 487
    , 488 (1872).
    "While the privilege is not absolute, it should be respected as
    far as reasonably possible consistent with fairness to a
    defendant" (quotation and citation omitted).    Commonwealth v.
    Shaughnessy, 
    455 Mass. 346
    , 353 (2009).    The scope of the
    informant privilege is limited by its underlying purpose:
    "where the disclosure of the contents of a communication will
    not tend to reveal the identity of an informer, the contents are
    not privileged."    Roviaro, 
    353 U.S. at 60
    .
    The informant privilege thus "extends to information that
    would tend to reveal the identity of the informant" (citation
    omitted).    United States v. Tzannos, 
    460 F.3d 128
    , 140 (1st Cir.
    2006).    As such, the privilege "not only protects the release of
    the name of the informant but also forbids the disclosure of
    details that would in effect identify the informant" (emphasis
    in original).    Commonwealth v. John, 
    36 Mass. App. Ct. 702
    , 706
    (1994).   See Commonwealth v. Douzanis, 
    384 Mass. 434
    , 436 n.4
    (1981) (disclosure of dates, times, and locations of all
    14
    meetings between defendant and informant, as well as copies of
    all written and oral statements made by informant, in effect
    would identify informant); John, 
    supra at 703, 707
     (same).
    The analysis of whether an informant's identity should be
    kept confidential under the privilege or disclosed "may best be
    described as generally occurring in two stages."     Bonnett, 
    472 Mass. at 846
    .   In the first stage of the analysis, a court makes
    a preliminary determination whether the Commonwealth properly
    asserted the informant privilege, see Mass. G. Evid.
    § 509(a)(1), and if so, whether the defendant has met his or her
    burden to challenge the Commonwealth's invocation of the
    privilege by establishing "an impermissible interference with
    [the defendant's] right to present a defense."     Bonnett, supra.
    The informant privilege may be asserted by the Commonwealth
    where the Commonwealth otherwise would be required to provide an
    informant's identity to a defendant as part of its discovery
    obligations under Mass. R. Crim. P. 14.     See id., quoting
    Roviaro, 
    353 U.S. at 59
    .    Should a defendant wish to overcome
    the informant privilege, the defendant bears the burden of
    challenging the Commonwealth's assertion.    Dias, 
    451 Mass. at 464
    .   "We have characterized a defendant's obligation at this
    juncture as 'relatively undemanding,' but it does require the
    defendant to articulate a basis sufficient for the judge to
    'assess the materiality and relevancy of the disclosure to the
    15
    defense, if that relevancy is not apparent from the nature of
    the case.'"   D.M., 
    480 Mass. at 1006
    , quoting Bonnett, supra at
    847.
    Only if both the Commonwealth and the defendant have met
    their burdens in the initial stage should a judge then proceed
    to the second stage of the analysis, where the judge must
    "decide whether the informant's identity and concomitant
    information are sufficiently 'relevant and helpful to the
    defense of an accused' that it must be disclosed."      Bonnett, 
    472 Mass. at 847
    , quoting Dias, 
    451 Mass. at 468
    .    This
    determination necessitates a balancing of "the public interest
    in protecting the flow of information against [the defendant's]
    right to prepare his [or her] defense."    Bonnett, supra at 847-
    848, quoting Roviaro, 
    353 U.S. at 62
    .     The inquiry at the
    balancing stage must be case-specific:    "[w]hether a proper
    balance renders nondisclosure erroneous must . . . tak[e] into
    consideration the crime charged, the possible defenses, the
    possible significance of the informer's testimony, and other
    relevant factors."    Roviaro, 
    supra.
       Where disclosure (1) is
    sufficiently "relevant and helpful to the defense of an accused"
    or (2) "is essential to a fair determination of a cause, the
    privilege must give way."    Dias, 
    supra,
     quoting Roviaro, 
    supra
    at 60–61.
    16
    c.   Application.   i.   Commonwealth's assertion of informant
    privilege.   The defendant argues that because she did not seek
    disclosure of the informant's name, and because the judge found
    that disclosure of the information requested would not reveal
    the informant's identity, the informant privilege does not
    apply.    She contends that the judge's order therefore should be
    reviewed in the context of a motion judge's broad discretion to
    order discovery under Mass. R. Crim. P. 14.10    We disagree.
    Rather, based on the record before us, we conclude that the
    extensive amount of information requested by the defendant
    would, in effect, reveal the informant's identity such that the
    informant's privilege is applicable to this case.11
    10The defendant does not refute the Commonwealth's
    assertion that the informant's safety would be in danger if his
    or her identity were revealed. Compare D.M., 480 Mass. at 1005
    (disclosure of identity of informant with current and prior
    involvement in firearms cases would endanger informant).
    11In concluding that the informant privilege has been
    properly asserted here, where the information requested would in
    effect reveal the informant's identity, we do not set forth a
    rigid test or add any additional step to the analysis laid out
    in Bonnett, 472 Mass. at 846. Rather, consideration of whether
    disclosure of requested information, short of an informant's
    name and address, might place an informant in danger has always
    been part of a case-specific inquiry into whether the informant
    privilege is properly invoked. See Commonwealth v. Amral, 
    407 Mass. 511
    , 526 n.11 (1990) (privilege properly asserted where
    disclosure of requested information "would be tantamount to
    revealing the informant's identity"); Commonwealth v. Douzanis,
    
    384 Mass. 434
    , 436 n.4 (1981) (applying privilege where
    requested information "would in effect identify the informant"
    and permitting judge on remand to consider "whether full or
    17
    Here, the search warrant issued to search the defendant's
    home and person relied on the informant's assertions that the
    informant had seen the defendant load and unload firearms inside
    her home within the thirty days prior to the application for the
    warrant.   The expansive nature of the ordered discovery would
    risk providing details that would allow the defendant, or others
    familiar with her home, to retrace their activities over the
    preceding thirty days and discern the identity of the informant
    on that basis.   See Commonwealth v. Benlien, 
    27 Mass. App. Ct. 834
    , 838 n.7 (1989) (date of controlled purchase remained
    undisclosed because of "need not to pinpoint the encounter and
    thus impair the anonymity of the informer").   Moreover, the
    informant has provided information leading to the arrest of
    three other individuals for firearms offenses, the execution of
    a search warrant that located firearms and drugs, and the arrest
    of one person on a default warrant.   The disclosure of the
    details of those events -- their dates, locations, and the names
    of the involved parties -- would permit those familiar with the
    informant to piece together a detailed picture of the
    partial disclosure of the demanded information would in fact
    reveal the informant's identity"); Commonwealth v. John, 
    36 Mass. App. Ct. 702
    , 706 (1994) ("the privilege not only protects
    the release of the name of the informant but also forbids the
    disclosure of details that would in effect identify the
    informant" [emphasis in original]). See also Roviaro v. United
    States, 
    353 U.S. 53
    , 60 (1957) (contemplating whether contents
    of communication would "tend to" reveal informant's identity).

    informant's assistance to law enforcement, effectively
    identifying the informant.12
    Given our conclusion that the requested disclosure would in
    effect disclose the informant's identity, and the parties'
    agreement -- appropriate in the circumstances of this case --
    that disclosure of the informant's identity would place the
    informant in danger, we conclude that the Commonwealth properly
    met its burden to invoke the informant privilege.
    ii.   Defendant's burden to make showing of materiality and
    relevancy.   Because the Commonwealth properly invoked the
    informant privilege, the burden shifted to the defendant to
    "challeng[e] the assertion of the privilege as an impermissible
    interference with . . . her right to present a defense."
    Bonnett, 472 Mass. at 846.     While a defendant's burden at this
    stage is "relatively undemanding," see D.M., 
    480 Mass. at 1006
    ,
    quoting Bonnett, supra at 847, "[c]ases that have required
    disclosure have done so on a 'standard of materiality or
    12As noted supra, the motion judge's contrary finding,
    based solely on the documentary evidence, is due no deference.

    481 Mass. 710

    denied, 
    140 S. Ct. 247 (2019)
    ; Commonwealth v. Tremblay, 
    480 Mass. 645
    , 654-655 (2018). We note only that, to the extent the
    motion judge relied solely on the substitution of a code for the
    informant's name in concluding that disclosure of the requested
    evidence would not reveal the informant's identity, her reliance
    was inconsistent with the fact-specific inquiry into the
    practical implications of disclosure that this stage of the
    analysis demands. Compare Douzanis, 
    384 Mass. at
    436 n.4; John,
    36 Mass. App. Ct. at 706-707.

    something roughly akin thereto," Dias, 
    451 Mass. at 469
    , quoting
    Commonwealth v. Lugo, 
    406 Mass. 565
    , 571 (1990).     "As to
    materiality, we have said that the 'proper inquiry' concerns
    'whether disclosure would have provided material evidence needed
    by the defendant for a fair presentation of his case to the
    jury.'"   Dias, 
    supra,
     quoting Commonwealth v. Madigan, 
    449 Mass. 702
    , 706 (2007).
    A defendant must make "some offering" so that the judge
    "may assess the materiality and relevancy of the disclosure to
    the defense."   Dias, 
    451 Mass. 469
    , quoting Swenson, 
    368 Mass. at 276
    .   "In other words, the defendant has some obligation to
    show an exception to the privilege that the informer remain
    anonymous."   Dias, 
    supra,
     quoting Swenson, 
    supra.
       A distinction
    exists between a demand for disclosure for pretrial purposes,
    where the issue is probable cause for arrest or a search, and a
    demand for disclosure at trial, where the issue is the
    defendant's guilt or innocence.   See Lugo, 
    406 Mass. at 571
    .
    While the standards of disclosure for pretrial purposes are
    "more demanding" than those applicable when disclosure is sought
    for trial purposes, in either instance a defendant nevertheless
    must offer some evidence to support the materiality and
    relevancy of disclosure.   See D.M., 
    480 Mass. at 1006
    .
    The defendant maintains that the requested discovery was
    material and relevant to an anticipated "Franks/Amral" motion
    20
    challenging the accuracy of the information in the warrant.      See
    Amral, 
    407 Mass. at 520
    , citing Franks, 
    438 U.S. at 155-156
    .     As
    she did at the motion hearing, the defendant argues on appeal
    that she demonstrated her material need for the requested
    information by stating that there was "no track record"
    supporting the informant's reliability and no other means of
    verifying the information in the affidavit.   The Commonwealth
    argues that the defendant made an insufficient showing that the
    requested information was material and relevant to a pretrial
    defense or to a defense at trial.
    Although we have no doubt that the motion judge engaged in
    a good faith effort to weigh the interests involved, as
    presented to her by the parties, we conclude that the judge
    erred in finding that the defendant made a sufficient showing of
    materiality to satisfy her burden in the initial stage of the
    analysis under Bonnett, 
    472 Mass. at 847
    , and accordingly, the
    judge abused her discretion in ruling that disclosure was
    warranted, whether for pretrial or trial purposes.
    To be entitled to a Franks/Amral hearing, a defendant must
    "by affidavit assert[] facts which cast a reasonable doubt on
    the veracity of material representations made by the affiant
    concerning a confidential informant."   Amral, 
    407 Mass. at 522
    .
    The defendant did not assert any case-specific facts in her
    original motion, at either hearing, or in the requested
    21
    affidavit that cast a reasonable doubt on the informant's
    veracity or the facts in the affidavit.   Indeed, although the
    defendant's motion cited to Amral, 
    supra,
     the record does not
    indicate that the defendant meant to assert that the search
    warrant affidavit was untruthful -- only that the possibility of
    its untruthfulness existed, due to the lack of information about
    the informant's "track record" and information about the
    investigation itself.   However, "[m]ere suspicion that there was
    no informant, or that the informant's 'reliability' credentials
    have been misstated, or that his information was other than as
    recited by the affiant," as was the case here, does not rise to
    the level of an articulated challenge that warrants a
    Franks/Amral hearing.   
    Id.
       See Douzanis, 
    384 Mass. at 439
    (requiring something more than "naked claim" that affiant
    fabricated information before ordering Franks/Amral hearing).
    The defendant's suggestion that the requested information may
    bear on an eventual Franks/Amral defense, without more, was not
    a sufficiently articulated basis that would have allowed the
    judge to assess the materiality and relevancy of the disclosure.
    See John, 36 Mass. App. Ct. at 706 ("A discovery motion, by
    itself, seeking information about facts contained in the warrant
    affidavit, is not sufficient to overcome [the warrant's]
    presumption of validity").
    22
    Finally, the brief, vague, and conclusory assertion in
    defense counsel's affidavit that the requested information was
    "needed to prepare for trial" does not pass muster for a showing
    of materiality.    A judge "cannot be required to assess the need
    for disclosure . . . without some guidance" as to the "scheme of
    the defense."     Swenson, 
    368 Mass. at 276
    .   Although the
    defendant's burden at this stage is "relatively undemanding,"
    see Bonnett, 
    472 Mass. at 847
    , it was not met here, and the
    motion judge abused her discretion in concluding otherwise when
    faced with this evidentiary record.13
    3.   Conclusion.   We hold that the information requested by
    the defendant would in effect disclose the informant's identity
    and that the defendant failed to show that the requested
    information was relevant and material to her defense.
    Accordingly, the matter is remanded to the county court for
    entry of a judgment reversing the motion judge's order allowing
    the defendant's motion for discovery and remanding the matter to
    13Because we find that the defendant has failed to meet her
    burden, albeit a "relatively undemanding" one, at the initial
    stage of the analysis under Bonnett, 472 Mass. at 847, "[w]e
    need not speculate about what the results of a second-stage
    Roviaro balancing exercise might have been." Id. at 850.

    the Boston Municipal Court for further proceedings consistent
    with this opinion.14
    So ordered.
    14On remand, the motion judge may entertain a request, if
    any is made, for compromise relief that might allow disclosure
    of some lesser amount of information "while minimizing danger to
    the [informant]" (citation omitted). Bonnett, 
    472 Mass. at 850
    .
    We express no view as to the appropriateness of any potential
    compromise. Rather, it is within the motion judge's discretion
    to consider any such request in the first instance, consistent
    with the legal principles discussed supra.
