    AMERICAN CIVIL LIBERTIES UNION OF NEW HAMPSHIRE & a.
    v.
    CITY OF CONCORD
    Argued: February 11, 2021
    Opinion Issued: December 7, 2021
    American Civil Liberties Union of New Hampshire Foundation, of
    Concord (Gilles R. Bissonnette and Henry R. Klementowicz on the brief, and
    Henry R. Klementowicz orally), for the plaintiffs.
    City Solicitor’s Office, of Concord (James W. Kennedy, city solicitor, on
    the brief and orally), for the defendant.
    BASSETT, J. The plaintiffs, the American Civil Liberties Union of New
    Hampshire (ACLU) and the Concord Monitor, appeal an order of the Superior
    Court (Kissinger, J.) ruling that portions of a contract between an equipment
    vendor and the defendant, the City of Concord, for the purchase of “covert
    communications equipment” are exempt from disclosure under the Right-to-
    Know Law. See RSA ch. 91-A (2013 & Supp. 2020). The plaintiffs argue that
    the City failed to meet its burden of demonstrating that the redacted portions
    of the contract are exempt from disclosure, and that the trial court erred when
    it held an ex parte in camera hearing, during which the City presented
    evidence supporting exemption. We affirm in part, reverse in part, and
    remand.
    The following facts are undisputed or are otherwise supported by the
    record. On May 10, 2019, the Concord City Manager submitted a proposed
    2019-2020 operating budget to the Mayor and the City Council. Included
    under the proposed police budget was a $5,100 line item for “Covert
    Communications Equipment.” On May 24, the Monitor published a news
    article titled “Concord’s $66.5M budget proposal has its secrets,” which
    discussed the line item. The Monitor reported that one of the City Councilors
    had asked the City Manager if he could provide a “hint” as to the nature of the
    equipment, but that the Manager had responded, “I don’t know how to answer
    that question[] without ‘answering it.’” The City Manager did not publicly
    identify the equipment, saying only that it was not body cameras or a drone.
    The Monitor reported that the Chief of Police had stated that the City has a
    non-disclosure agreement with the equipment’s vendor that prevents the City
    from publicizing the nature of the equipment.
    Shortly thereafter, the ACLU and the Monitor filed separate Right-to-
    Know requests with the City. The ACLU requested “[d]ocuments sufficient to
    identify the specific nature of the ‘covert communications equipment’ sought by
    the Concord Police Department,” and “[a]ny contracts or agreements between
    the Concord Police Department or the City of Concord and the vendor providing
    the ‘covert communications equipment.’” The Monitor similarly requested
    “documents related to the $5,100 ‘covert communications equipment’ sought
    by the Concord Police Department,” including “any contracts or agreements
    between the Concord Police Department or the City of Concord and the vendor
    providing the equipment, documents that detail the nature of the equipment,
    and the line items associated with the equipment in the department’s budget.”
    The City responded to both requests by disclosing a partially-redacted
    29-page, single-spaced “License & Services Agreement” between the City and
    the equipment vendor. The redactions included the name of the vendor, the
    state law that governs the agreement, the nature of the equipment, the type of
    information gathered by the vendor, and how the vendor uses that information.
    Most pages had fewer than 20 words redacted, and most of the redactions were
    either one or a few words. Representative of the redactions is the following:
    “Law enforcement agencies may direct us to collect a wide variety of
    information from your [redacted] when you use the [redacted] services. The
    information may include: [multiple clauses redacted].” The disclosed portions
    of the agreement included the following: (1) the vendor would provide a
    “Website, Applications, [and] Services”; (2) the City would maintain ownership
    of “location information” and “other data” generated from its use of the Website,
    Applications, and Services; (3) the vendor would be indemnified for any losses
    2
    or damages incurred by the City due to a “suspension” of the Application; and
    (4) the City agreed to abide by the vendor’s “Acceptable Use Policy and Privacy
    Policy.”
    In a letter accompanying the redacted agreement, the City explained that
    the redactions were necessary because the agreement “contains confidential
    information relative to surveillance technology that is exempt from disclosure
    under the law enforcement exemption” in Murray v. New Hampshire Division of
    State Police, 
    154 N.H. 579
    , 582 (2006). In Murray, we observed that the Right-
    to-Know Law does not explicitly address requests for law enforcement records
    or information, and we adopted the six-prong test under the federal Freedom of
    Information Act (FOIA) for evaluating requests for law enforcement records.
    Murray, 154 N.H. at 582. Under FOIA, the government may exempt from
    disclosure:
    records or information compiled for law enforcement purposes, but
    only to the extent that the production of such law enforcement
    records or information (A) could reasonably be expected to interfere
    with enforcement proceedings, (B) would deprive a person of a right
    to a fair trial or an impartial adjudication, (C) could reasonably be
    expected to constitute an unwarranted invasion of personal privacy,
    (D) could reasonably be expected to disclose the identity of a
    confidential source, including a State, local, or foreign agency or
    authority or any private institution which furnished information on
    a confidential basis, and, in the case of a record or information
    compiled by criminal law enforcement authority in the course of a
    criminal investigation or by an agency conducting a lawful national
    security intelligence investigation, information furnished by a
    confidential source, (E) would disclose techniques and procedures
    for law enforcement investigations or prosecutions, or would disclose
    guidelines for law enforcement investigations or prosecutions if such
    disclosure could reasonably be expected to risk circumvention of the
    law, or (F) could reasonably be expected to endanger the life or
    physical safety of any individual . . . .
    
    5 U.S.C. § 552
    (b)(7) (2018). We have referred to the six prongs collectively as
    the Murray exemption. See 38 Endicott St. N. v. State Fire Marshal, 
    163 N.H. 656
    , 661 (2012). In its letters to the plaintiffs, the City quoted Murray and
    invoked prong (E).
    In response, the plaintiffs filed a petition in the superior court seeking
    disclosure of the redacted portions of the agreement. See RSA 91-A:7 (Supp.
    2020). The City responded that the redacted information was exempt from
    disclosure under Murray, and that it would not disclose “the name of the
    vendor or any of the information redacted from the documents as such
    3
    disclosure could reasonably be expected to interfere with pending enforcement
    proceedings, disclose techniques and procedures for law enforcement
    investigations, risk circumvention of the law and endanger the life or physical
    safety of any individual.” In effect, the City invoked prongs (A), (E), and (F) of
    the Murray exemption. See Murray, 154 N.H. at 582.
    Shortly thereafter, the plaintiffs served a request for production of
    documents, see Super. Ct. R. 24, seeking an unredacted copy of the agreement,
    as well as other documents and contracts responsive to their Right-to-Know
    requests. The plaintiffs proposed that the documents be produced “subject to
    a mutually agreeable protective order.” The City filed a motion to quash,
    arguing that a “petitioner cannot be allowed to circumvent the Right-to-Know
    Law exemptions simply by filing a Right-to-Know lawsuit and obtaining
    exempted materials through discovery.” The City reiterated its position that
    the redacted information was “not subject to disclosure under [prongs] A, E
    and F,” and submitted a two-page affidavit from the Chief of Police in which he
    stated that disclosure of the information could reasonably be expected to
    interfere with pending investigations, risk circumvention of the law, and
    endanger the life or physical safety of officers. See Murray, 154 N.H. at 582.
    With the plaintiffs’ assent, the City also submitted an unredacted copy of the
    agreement to the trial court for in camera review. In addition, the City filed a
    motion for an ex parte in camera hearing, offering to make a police department
    representative available to answer the court’s questions regarding the
    redactions. The plaintiffs objected.
    In October 2019, the court held a 45-minute hearing on the pending
    motions. During the hearing, the court characterized the Chief’s affidavit as
    “conclusory.” In a subsequent written order, the court ruled that the City had
    failed to demonstrate that the redacted information was exempt from
    disclosure but that the court needed additional information before reaching a
    final decision. It therefore granted the City’s motion for an ex parte in camera
    hearing. Neither the plaintiffs, nor their counsel, were permitted to attend.
    At the ex parte in camera hearing, the Chief of Police testified as to the
    nature of the equipment and how it is used by the department. He explained
    how disclosing the name of the vendor and the nature of the equipment would
    undermine law enforcement investigations, risk circumvention of the law, and
    endanger lives. Although the transcript of the hearing is part of the record on
    appeal, the plaintiffs have never had access to the transcript. The trial court
    ruled that the redacted portions of the agreement are exempt from disclosure
    under prongs (A), (E), and (F) of the Murray exemption. This appeal followed.
    On appeal, the plaintiffs argue that the trial court erred when it ruled
    that the redacted information is exempt from disclosure under prongs (A), (E),
    and (F), and also erred when it conducted the ex parte in camera hearing. The
    4
    City counters that it met its burden to demonstrate exemption under all three
    prongs, and that it was within the discretion of the trial court to hold the ex
    parte in camera hearing. We conclude that the court did not err when it
    conducted the hearing, and that it properly determined that most of the
    redacted information was exempt from disclosure. However, we also conclude
    that it erred by not disclosing one provision of the agreement.
    “We review the trial court’s interpretation of the Right-to-Know Law and
    its application of the law to undisputed facts de novo.” 38 Endicott St. N., 163
    N.H. at 660. “The purpose of the Right-to-Know Law is to ensure both the
    greatest possible public access to the actions, discussions and records of all
    public bodies, and their accountability to the people.” Montenegro v. City of
    Dover, 
    162 N.H. 641
    , 645 (2011) (quotation omitted). “Thus, the Right-to-Know
    Law helps further our state constitutional requirement that the public’s right of
    access to governmental proceedings and records shall not be unreasonably
    restricted.” 
    Id.
     We construe provisions favoring disclosure broadly, while
    construing exemptions narrowly. Murray, 154 N.H. at 581. Therefore, when a
    public entity seeks to avoid disclosure of material under the Right-to-Know
    Law, that entity bears a heavy burden to shift the balance toward
    nondisclosure. Reid v. N.H. Attorney Gen., 
    169 N.H. 509
    , 532 (2016). “In
    interpreting provisions of the . . . Right-to-Know Law, we often look to the
    decisions of other jurisdictions interpreting similar provisions of other statutes
    for guidance, including federal interpretations of [FOIA].” 38 Endicott St. N.,
    163 N.H. at 660; see Murray, 154 N.H. at 581.
    We first address the plaintiffs’ argument that the trial court erred when it
    conducted the ex parte in camera hearing. The plaintiffs assert that the court
    erred because it is a “standard requirement that all evidence and argument
    presented to a judge should be presented to opposing counsel,” and no statute
    or rule authorizes a “deviation” from that requirement in a Right-to-Know Law
    case. They contend that holding the hearing was antithetical to the adversarial
    process, and that the hearing was a fundamentally unfair and unreliable
    procedure because it denied them the opportunity to cross-examine the City’s
    witnesses and highlight shortcomings in the City’s evidence.
    The Right-to-Know Law requires “the necessary accommodation of . . .
    competing interests.” Clay v. City of Dover, 
    169 N.H. 681
    , 686 (2017)
    (quotation omitted). On one hand, when the government seeks to withhold
    requested documents, it has “exclusive control of vital information.” Union
    Leader Corp. v. N.H. Housing Fin. Auth., 
    142 N.H. 540
    , 548 (1997). Because
    only the government has possession of the withheld documents, the petitioner
    must argue that a document is not exempt from disclosure with only “limited
    knowledge” of the document’s contents. 
    Id.
     For that reason, the government
    bears the burden of demonstrating that a document is exempt from disclosure,
    see Murray, 154 N.H. at 581, and it must provide a justification for exemption
    5
    sufficient for the trial court to determine the applicability of the claimed
    exemption and for the petitioner to argue against exemption with some
    specificity. See N.H. Housing Fin. Auth., 142 N.H. at 548-50 (explaining the
    purpose of a Vaughn index, a procedure often used in cases with a large
    number of documents potentially responsive to a Right-to-Know request, in
    which the government produces a general description of each document
    withheld and a justification for nondisclosure). Unless the government
    discloses “as much information as possible without thwarting the claimed
    exemption’s purpose, the adversarial process is unnecessarily compromised.”
    Id. at 549 (quotation omitted).
    On the other hand, we have recognized that the government may take
    precautionary measures in order to prevent disclosure of the very information
    that it hopes to keep confidential. We approved the government submitting an
    affidavit to the court in order to justify its withholding of documents, and
    deemed that affidavit sufficient when it “fairly describe[d] the content of the
    material withheld and adequately state[d] the grounds for nondisclosure.” 38
    Endicott St. N., 163 N.H. at 667 (quotation and brackets omitted). We have
    also explained that when the government seeks to justify withholding
    documents under prong (A), “generic determinations of likely interference [with
    enforcement proceedings] often will suffice,” and the government’s description
    of the withheld information should not be so detailed “as to reveal the nature
    and scope of the investigation.” Murray, 154 N.H. at 583. Thus, the
    government’s justification for exemption need not be so specific as to reveal the
    withheld information, and the requesting party is not entitled to learn all of the
    information that forms the basis for the withholding. See id.
    To balance these competing interests, the trial court may, in some
    circumstances, utilize in camera procedures before reaching a decision
    regarding disclosure. In Union Leader Corp. v. City of Nashua, we reviewed the
    trial court’s denial of a Right-to-Know petition based upon prong (C) of the
    Murray exemption, which exempts from disclosure records or information
    compiled for law enforcement purposes when disclosure would “constitute an
    unwarranted invasion of privacy.” Union Leader Corp. v. City of Nashua, 
    141 N.H. 473
    , 475 (1996) (quotation omitted). We affirmed the trial court’s in
    camera review of the documents at issue without counsel present, explaining
    that “ex parte in camera review of records whose release may cause an invasion
    of privacy is plainly appropriate,” but that this procedure should “be used
    cautiously and rarely.” Id. at 478. We explained that, to facilitate appellate
    review, when the trial court conducts an in camera review under such
    circumstances, “a record must be taken of any hearings that are held, whether
    counsel for one or both parties are present.” Id. (emphasis added).
    Accordingly, although City of Nashua involved only in camera review of
    documents and not an ex parte in camera hearing, we suggested that there
    may be circumstances when the trial court may hold an ex parte in camera
    hearing before applying the Murray exemption. See id.
    6
    Since City of Nashua, we have not addressed the use of ex parte in
    camera hearings in Right-to-Know Law cases. In the absence of controlling
    New Hampshire precedent construing RSA chapter 91-A, we look to federal
    FOIA cases for guidance. See 38 Endicott St. N., 163 N.H. at 660. FOIA
    expressly permits trial courts to examine documents in camera before
    determining whether they may be withheld. See 
    5 U.S.C. § 552
    (a)(4)(B) (2018).
    Many federal circuit courts have recognized that trial courts may utilize
    procedures that are “necessary to prevent the litigation process from revealing
    the very information the agency hopes to protect.” American Civil Liberties
    Union v. C.I.A., 
    710 F.3d 422
    , 432-33 (D.C. Cir. 2013) (noting that, in some
    circumstances, a court may permit the government to submit a Vaughn index
    in camera). Those procedures include the consideration of ex parte affidavits
    and the conduct of ex parte proceedings. See, e.g., New York Times Co. v. U.S.
    Dept. of Justice, 
    806 F.3d 682
    , 685, 689 (2d Cir. 2015) (allowing government to
    present ex parte in camera oral argument to the court immediately before
    hearing arguments from all parties in open court); Manna v. U.S. Dept. of
    Justice, 
    51 F.3d 1158
    , 1163 (3d Cir. 1995) (explaining that, if public disclosure
    of the information needed to reach a decision would frustrate the exemption,
    the court may permit the government to submit sealed affidavits); Long v.
    United States I.R.S., 
    742 F.2d 1173
    , 1182 (9th Cir. 1984) (observing that,
    under certain circumstances, a court may accept “nonpublic affidavits” or
    “proceed ex parte to the extent it deems necessary to protect the integrity” of
    the information claimed to be exempt from disclosure).
    At the same time, federal circuit courts emphasize that these procedures
    should be used in only limited circumstances, and have held that, prior to
    employing ex parte procedures, the trial court must first require the
    government to submit public affidavits or testimony providing “as detailed
    public disclosure as possible of the government’s reasons for withholding
    documents.” Lion Raisins v. U.S. Dept. of Agriculture, 
    354 F.3d 1072
    , 1082-84
    (9th Cir. 2004) (reversing trial court’s withholding of documents under law
    enforcement exemption where government submitted no public affidavits
    justifying application of the exemption and court relied solely on government’s
    ex parte affidavit), overruled on other grounds by Animal Legal Defense Fund v.
    U.S. F.D.A., 
    836 F.3d 987
    , 989-90 (9th Cir. 2016); see also Lykins v. United
    States Dept. of Justice, 
    725 F.2d 1455
    , 1465 (D.C. Cir. 1984). Detailed public
    disclosure is “necessary to restore, to the extent possible, a traditional
    adversarial proceeding by giving the party seeking the documents a meaningful
    opportunity to oppose the government’s claim of exemption.” Lion Raisins, 
    354 F.3d at 1083
    . Only if the government’s detailed public disclosures fail to
    “provide a sufficient basis for a decision” may the trial court accept ex parte
    affidavits or conduct ex parte proceedings, and it may do so only to the limited
    extent necessary to protect the information from disclosure. Pollard v. F.B.I.,
    
    705 F.2d 1151
    , 1154 (9th Cir. 1983); Long, 
    742 F.2d at 1182
    .
    7
    This approach, drawn from federal law, is consonant with our Right-to-
    Know Law jurisprudence. See, e.g., N.H. Housing Fin. Auth., 142 N.H. at 551
    (“In camera examination is not a substitute for the [defendant’s] obligation to
    provide detailed public indexes and justifications whenever possible.”
    (quotation omitted)); City of Nashua, 141 N.H. at 478 (implying that ex parte in
    camera hearings may be appropriate under some circumstances involving the
    Murray exemption). We therefore hold that, in cases involving the Murray
    exemption, a trial court may exercise its discretion to hold an ex parte in
    camera hearing — but only after it has required the government to make as
    complete and detailed a public disclosure justifying exemption as possible, and
    determined that the disclosure nonetheless fails to provide a sufficient basis for
    it to make a decision. This threshold determination will ensure that ex parte in
    camera hearings are “used cautiously and rarely.” City of Nashua, 141 N.H. at
    478. We will review both a trial court’s finding that this threshold has been
    met and its decision to hold an ex parte in camera hearing under our
    unsustainable exercise of discretion standard. See Larson v. Department of
    State, 
    565 F.3d 857
    , 869-70 (D.C. Cir. 2009) (reviewing trial court’s decision
    about whether to conduct in camera review of documents and ex parte
    declaration for abuse of discretion); State v. Lambert, 
    147 N.H. 295
    , 296 (2001)
    (explaining that we refer to the abuse of discretion standard as the
    unsustainable exercise of discretion standard and describing the requirements
    of that standard).
    The plaintiffs argue that, although federal cases such as New York Times
    Co. support the proposition that a court may conduct an ex parte in camera
    hearing under certain circumstances, those cases are distinguishable because
    they involve national security concerns that are not present here. The plaintiffs
    contend that, although a court may hold an ex parte in camera hearing when
    the withheld documents contain highly sensitive national security information,
    such as information regarding terrorism investigations, the information
    withheld in this case does not warrant such protection. We are not persuaded.
    The government is not required to publicly disclose information that
    would undermine the very purpose of the exemption, see N.H. Housing Fin.
    Auth., 142 N.H. at 549, and procedures such as ex parte hearings and
    affidavits are designed to safeguard the interests protected by the exemption,
    while still providing the court with a “reasonable basis to evaluate the claim of
    privilege.” American Civil Liberties Union, 710 F.3d at 432-33 (quotation
    omitted); see New York Times Co., 806 F.3d at 689. Regardless of whether the
    government claims exemption for national security or law enforcement reasons,
    an ex parte in camera hearing is sometimes necessary to “accommodat[e] . . .
    the competing interests involved.” Clay, 169 N.H. at 686 (quotation omitted);
    see Manna, 
    51 F.3d at 1164-65
     (concluding, based in part on government’s ex
    parte affidavits, that requested documents were exempt from disclosure
    because disclosure could reasonably be expected to interfere with law
    enforcement proceedings).
    8
    Having articulated the applicable standard, we now analyze whether the
    court erred when it conducted the ex parte in camera hearing in this case.
    Prior to the ex parte in camera hearing, the City had publicly disclosed a
    partially redacted copy of the “License & Services Agreement” between the City
    and the equipment vendor. In its response to the plaintiffs’ requests, the City
    explained that the redacted portions of the agreement contained “confidential
    information relative to surveillance technology,” and asserted that disclosure
    “could compromise the effectiveness of the technology and allow individuals
    who are the subjects of investigations to employ countermeasures.” The City
    subsequently filed a public affidavit from the Chief of Police, in which he
    asserted that disclosure of the redacted information “could tip off those
    persons who are subject to the pending investigations as to the strategy in
    implementing the specific techniques in the investigations,” and provide “those
    who wish to engage in criminal activity with the ability to adjust their behaviors
    in an effort to avoid detection.” In effect, through the Chief’s affidavit and
    during the hearing on the City’s motion for an ex parte in camera hearing, the
    City represented that additional public disclosure of the reasons for the
    redactions would undermine the interests protected by the Murray exemption.
    After its review of this information and the unredacted agreement, the
    trial court concluded that the City’s representations and public disclosures
    were inadequate to justify the redactions, and that “it need[ed] further
    information before reaching a decision.” The trial court therefore granted the
    City’s motion for an ex parte in camera hearing. In making that determination,
    the court credited the City’s claims that additional public disclosure of the
    reasons for the redactions might undermine the purpose of the claimed
    exemptions. See 38 Endicott St. N., 163 N.H. at 659, 666-68 (ruling that
    documents related to State Fire Marshal’s investigation of a fire were exempt
    from disclosure under Murray prong (A) based upon representations made in
    fire investigator’s affidavit, which “the trial court was entitled to credit”);
    Citizens for Resp. & Ethics v. Dept. of Justice, 
    746 F.3d 1082
    , 1098 (D.C. Cir.
    2014) (observing that courts “give deference to an agency’s predictive judgment
    of the harm that will result from disclosure”); Long, 
    742 F.2d at 1182
    (explaining that, in cases involving “sensitive areas” such as national security
    and law enforcement, “courts have accorded special deference to an agency’s
    detailed affidavits”). The court also considered the possibility of holding a
    closed hearing with only counsel for all parties present, but rejected that
    approach due to the “sensitive nature of the information in question,” and the
    potential for harm if the court did not “keep disclosure of the information to a
    minimum.”
    We conclude that the trial court satisfied the standard we set forth
    above: as a threshold matter, the court required the City to make as detailed a
    public disclosure as possible without compromising the purpose of the claimed
    exemption, and it then concluded that the public disclosure was insufficient for
    9
    it to reach a decision. After the court observed that ex parte proceedings
    should rarely be used, it reasoned that, because it could not reach a decision
    “without learning more about . . . the covert communications equipment,” and
    due to the risks posed by additional public disclosure, an ex parte in camera
    hearing was appropriate. Under these circumstances, we conclude that the
    trial court’s decision to conduct an ex parte in camera hearing was a
    sustainable exercise of discretion.
    Nonetheless, we take this occasion to emphasize that ex parte in camera
    hearings “should be used cautiously and rarely.” City of Nashua, 141 N.H. at
    478. If a trial court is unsatisfied with a defendant’s public disclosures, it may
    “require [the defendant] to submit more detailed public affidavits before
    resorting to in camera review” of the withheld documents or ex parte affidavits.
    Pollard, 705 F.2d at 1154. Trial courts should also carefully consider whether
    other steps short of an ex parte in camera hearing — such as holding a closed
    hearing with only counsel present, or with only counsel and all parties present
    — would “accommodat[e] . . . the competing interests involved.” Clay, 169 N.H.
    at 686.
    Having affirmed the trial court’s decision to conduct the ex parte in
    camera hearing, we now turn to the court’s ruling that the redacted
    information is exempt from disclosure under prongs (A), (E), and (F) of the
    Murray exemption. See Murray, 154 N.H. at 582. The plaintiffs are in a
    difficult position because they have not had access to the unredacted
    agreement. They do not dispute that the redacted information was “compiled
    for law enforcement purposes,” id.; however, they argue that the City failed to
    meet its burden of demonstrating that the redacted information is exempt from
    disclosure under any of the three identified prongs of the Murray exemption.
    They contend that any harm that could result from disclosure is speculative,
    that the City’s public explanations for exemption were conclusory, and that the
    information withheld by the City is materially different from the information
    that we ruled was exempt from disclosure in Montenegro. The City counters
    that it met its burden of demonstrating that all of the redacted information is
    exempt under prongs (A), (E), or (F) of the Murray exemption.
    We note that both parties make blanket arguments regarding the
    redacted information — the City asserts that all of the redactions are justified,
    while the plaintiffs contend that none of them are. But whether the City met
    its burden as to the redacted information is not an all-or-nothing proposition.
    Our task is to examine each redaction in turn in light of the applicable law.
    After doing so, we conclude that the trial court did not err in ruling that the
    following information is exempt from disclosure under prong (E) of the Murray
    exemption: the name of the vendor, the nature of the equipment, the type of
    information gathered by the vendor, and how the vendor uses that information.
    And we affirm, by an equally divided court, the trial court’s nondisclosure of
    the choice-of-law provision. However, we also conclude that the court erred in
    10
    upholding the redaction of a clause in the agreement giving the vendor certain
    rights should the possibility of public disclosure of the technology arise. That
    provision of the agreement shall be disclosed on remand.
    We first address the redactions concerning the name of the vendor, the
    nature of the equipment, the type of information gathered by the vendor, and
    how the vendor uses that information. In Montenegro, we considered the
    extent to which the City of Dover could withhold information about the nature
    and implementation of surveillance equipment that it used for law enforcement
    purposes. See Montenegro, 162 N.H. at 643. Looking to federal cases
    construing FOIA for guidance, we explained that information is exempt from
    disclosure under prong (E) if disclosure “could lead to decreased effectiveness
    in future investigations by allowing potential subjects to anticipate and identify
    [investigation] techniques as they are being employed.” Id. at 647 (quotations
    omitted). We therefore concluded that “the precise locations of the City’s
    surveillance equipment, the recording capabilities for each piece of equipment,
    the specific time periods each piece of equipment [was] expected to be
    operational, and the retention time for any recordings” were exempt from
    disclosure under prong (E) because that information was “of such substantive
    detail that it could reasonably be expected to risk circumvention of the law by
    providing those who wish to engage in criminal activity with the ability to
    adjust their behaviors in an effort to avoid detection.” Id. at 647-48.
    Montenegro establishes that information may be exempt from disclosure
    under prong (E) even if it is not certain that disclosure would result in
    circumvention of the law. Rather, information is exempt if disclosure “could
    lead to decreased effectiveness in future investigations” by providing those who
    wish to engage in criminal activity with the “ability” to avoid detection. Id.
    (quotation omitted and emphasis added). The federal courts have similarly
    recognized that, under FOIA, information may be exempt under prong (E) even
    if it is not certain that disclosure would result in circumvention of the law. The
    federal courts have explained that prong (E) “sets a relatively low bar for the
    agency to justify withholding.” Blackwell v. F.B.I., 
    646 F.3d 37
    , 42 (D.C. Cir.
    2011). Prong (E) requires only that the agency demonstrate logically how the
    release of the requested information might create a risk of circumvention of the
    law. Mayer Brown LLP v. I.R.S., 
    562 F.3d 1190
    , 1193-94 (D.C. Cir. 2009)
    (ruling that information about what the IRS considered to be acceptable
    settlement ranges for tax evasion was exempt because disclosure might lead
    some taxpayers to conclude that the financial benefits of evasion would
    outweigh the risks from being caught). Thus, to meet its burden, the City was
    required to establish only that disclosure could reasonably be expected to risk
    circumvention of the law.
    We have reviewed the unredacted agreement and the transcript of the ex
    parte in camera hearing. We agree with the trial court that disclosing the
    name of the vendor, the nature of the equipment, the type of information
    11
    gathered by the vendor, and how the vendor uses that information, could
    reasonably be expected to risk circumvention of the law by allowing individuals
    to learn about the surveillance technology and take evasive measures against
    it. See Montenegro, 162 N.H. at 647-48. The surveillance technology at issue
    here was described by the trial court as a “confidential technique,” unlike the
    surveillance cameras at issue in Montenegro. See id. at 643; see also ACLU of
    Northern CA v. U.S. Dept. of Justice, 
    880 F.3d 473
    , 491 (9th Cir. 2018)
    (explaining that prong (E) of FOIA’s law enforcement exemption “exempts
    investigative techniques not generally known to the public” (quotation
    omitted)). Moreover, even if the surveillance technology were publicly known as
    a law enforcement technique, the redacted material would still be exempt
    because it would reveal the specific means by which the technology is
    employed by the City. See ACLU of Northern CA, 880 F.3d at 491; see also
    Blackwell, 
    646 F.3d at 42
     (specific techniques used by FBI to conduct forensic
    computer examinations were exempt from disclosure). Accordingly, the
    redacted information that falls within the categories listed above is exempt
    from disclosure.
    In addition, as to the choice-of-law provision, the court is equally divided
    as to whether the City met its burden of proving that the provision is exempt
    from disclosure under prongs (A), (E), or (F) of the Murray exemption.
    Therefore, the trial court’s ruling that this information is exempt from
    disclosure is affirmed. See PK’s Landscaping, Inc. v. N.E. Telephone Co., 
    128 N.H. 753
    , 754, 758 (1986) (affirming, by an equally divided court, order
    granting summary judgment).
    However, as to one specific provision, we conclude that the trial court
    erred when it found that the City had met its burden to justify nondisclosure.
    See Reid, 169 N.H. at 532. The City failed to offer, in either its public
    disclosures or at the ex parte hearing, any rationale for the redaction of a
    clause in the agreement giving the vendor certain rights should the possibility
    of public disclosure of the technology arise. Given the City’s failure to carry its
    burden as to this provision, the trial court committed error in ruling that the
    provision was exempt from disclosure. When, after receiving adequate notice
    and having multiple opportunities to justify withholding the information, a
    public entity fails to meet its burden, disclosure of the withheld information is
    appropriate. See N.H. Housing Fin. Auth., 142 N.H. at 551-52 (affirming trial
    court’s decision to order summary disclosure of documents inadequately
    described in Vaughn index, when party had repeatedly failed to comply with
    court’s order to produce an adequate index). Accordingly, we remand to the
    trial court and order that the clause described above be disclosed.
    Finally, two of the redactions contain information that the City
    subsequently disclosed in its responses to the plaintiffs’ Right-to-Know
    requests and in the Chief’s affidavit. Accordingly, the City has waived its right
    12
    to claim that the information is exempt from disclosure, and we order that the
    information be disclosed on remand. See American Civil Liberties Union, 710
    F.3d at 426 (recognizing that, under FOIA, “when an agency has officially
    acknowledged otherwise exempt information through prior disclosure, the
    agency has waived its right to claim an exemption with respect to that
    information”).
    Affirmed in part; reversed in
    part; and remanded.
    HICKS, HANTZ MARCONI, and DONOVAN, JJ., concurred.
