    SUMMARY*
    Freedom of Information Act
    The panel reversed the district court’s summary judgment
    in favor of plaintiffs, who brought an action under the
    Freedom of Information Act (“FOIA”) against the United
    States Department of Defense seeking the names of foreign
    students and instructors at the Western Hemisphere Institute
    for Security Cooperation.
    The panel held that the disclosure of the names of the
    foreign students and instructors would constitute a clearly
    unwarranted invasion of personal privacy, and was exempt
    from disclosure under Exemption 6 of FOIA. The panel held
    that the evidence submitted by the Department of Defense
    demonstrated that disclosure of the identities of the foreign
    students and instructors could give rise to harassment, stigma,
    or violence as a result of their association with the United
    States – exactly the sort of risks that courts have recognized
    as nontrivial.
    Judge Watford dissented, and he would affirm the district
    court’s summary judgment, because in his view the
    Department of Defense did not carry its burden of
    demonstrating that the students’ and instructors’ privacy
    interests outweighed the strong public interest in disclosures
    of their names.

    OPINION
    IKUTA, Circuit Judge:
    This case requires us to determine whether the names of
    foreign students and instructors at the Western Hemisphere
    Institute for Security Cooperation (WHINSEC) are exempt
    from disclosure under Exemption 6 of the Freedom of
    Information Act (FOIA). 5 U.S.C. § 552(b)(6). Because we
    conclude that the disclosure of these names “would constitute
    a clearly unwarranted invasion of personal privacy,” 
    id., we reverse
    the district court’s grant of summary judgment to the
    plaintiffs.
    I
    We begin with the factual background regarding the
    development of WHINSEC, the Department of Defense’s
    adjustments to its disclosure policy in light of the terrorist
    attacks of 2001, and the plaintiffs’ lawsuit.

    A
    The United States Army School of the Americas (SOA)
    opened in 1946 “for the purpose of providing military
    education and training to military personnel of Central and
    South American countries and Caribbean countries.”
    10 U.S.C. § 4415(b) (1987). In 1989, during the Salvadoran
    Civil War, Salvadoran soldiers gunned down six Jesuit priests
    as well as their housekeeper and her 16-year-old daughter. It
    was later reported that 19 of the 26 soldiers implicated in
    these deaths had attended SOA. These murders sparked
    protests against SOA and prompted the formation of School
    of the Americas Watch (SOAW), a human rights and
    advocacy group dedicated to monitoring SOA graduates and
    lobbying for closure of the school.1
    As part of these monitoring efforts, SOAW submitted a
    FOIA request to the Department of Defense (DOD) seeking
    the names of all former and current SOA students and
    instructors. The DOD granted the request in 1994, and
    disclosed the names of all SOA students and instructors
    dating back to the school’s formation in 1946. SOAW used
    the names to create a database containing the names,
    countries, and courses taken or taught by each attendee.
    1
    The dissent provides a much lengthier and more detailed discussion
    of SOA’s history, relying primarily on newspaper articles and other extra-
    record material. Dissent at 35–38. While this further illuminates the
    reasons for Congress’s decision to address these issues through legislative
    enactments, the dissent’s historical research is otherwise not relevant to
    the legal question before us: whether the public’s interest in monitoring
    the DOD’s performance of its current statutory duties with respect to
    WHINSEC outweighs the privacy interest of WHINSEC students and
    instructors.
    CAMERANESI V. U.S. DEP’T OF DEFENSE                      5
    In 1997, Congress sought to improve the human rights
    record of SOA by adopting the Leahy Amendments to the
    Foreign Operations Appropriations Act. See Foreign
    Operations, Export Financing, and Related Programs
    Appropriation Act, 1998, Pub. L. No. 105-118, § 570, 111
    Stat. 2386, 2429 (1997).2 The Leahy Amendments precluded
    the DOD from providing congressionally appropriated funds
    to any unit of a foreign country’s security forces if there was
    credible evidence that the unit “has committed gross
    violations of human rights,” unless the Secretary of State
    reported to Congress that the foreign government was “taking
    2
    Specifically, the Leahy Amendments stated:
    None of the funds made available by this Act may be
    provided to any unit of the security forces of a foreign
    country if the Secretary of State has credible evidence
    that such unit has committed gross violations of human
    rights, unless the Secretary determines and reports to
    the Committees on Appropriations that the government
    of such country is taking effective measures to bring the
    responsible members of the security forces unit to
    justice: Provided, That nothing in this section shall be
    construed to withhold funds made available by this Act
    from any unit of the security forces of a foreign country
    not credibly alleged to be involved in gross violations
    of human rights: Provided further, That in the event
    that funds are withheld from any unit pursuant to this
    section, the Secretary of State shall promptly inform the
    foreign government of the basis for such action and
    shall, to the maximum extent practicable, assist the
    foreign government in taking effective measures to
    bring the responsible members of the security forces to
    justice.
    § 570, 111 Stat. at 2429.
    6          CAMERANESI V. U.S. DEP’T OF DEFENSE
    effective measures to bring the responsible members of the
    security forces unit to justice.” 
    Id. Congress reenacted
    the Leahy Amendments in subsequent
    appropriations bills3 until 2008, when the amendments were
    codified as part of the DOD appropriations rules, 10 U.S.C.
    § 2249e, and the Foreign Assistance Act, 22 U.S.C. § 2151 et
    seq. The provisions pertaining to the DOD, 10 U.S.C.
    § 2249e, state that no funds “made available to the
    Department of Defense . . . may be used for any training,
    equipment, or other assistance for a unit of a foreign security
    force if the Secretary of Defense has credible information that
    the unit has committed a gross violation of human rights.” 
    Id. § 2249e(a)(1).
    The law further requires the Secretary of
    Defense to consult with the Secretary of State to “ensure that
    prior to a decision to provide any training, equipment, or
    other assistance to a unit of a foreign security force full
    consideration is given to any credible information available
    to the Department of State relating to human rights violations
    by such unit.” 
    Id. § 2249e(a)(2).
    The statute does not require
    the DOD to continue to monitor the performance of such
    units or the careers of individual members of those units after
    they leave WHINSEC. The provisions pertaining to the
    Secretary of State impose a similar ban on providing

    assistance to a unit believed to have committed human rights
    violations. 22 U.S.C. § 2378d.4 As later amended in 2011,
    the statute also directs the Secretary of State to “establish, and
    periodically update, procedures to . . . ensure that when an
    individual is designated to receive United States training,
    equipment, or other types of assistance the individual’s unit
    is vetted as well as the individual.” 
    Id. § 2378d(d)(5).5
    If the
    Secretary determines that a particular unit is ineligible for
    assistance, the Secretary is required to “make publicly
    available, to the maximum extent practicable, the identity of
    those units for which no assistance shall be furnished.” 
    Id. § 2378d(d)(7).
    As with the statute regulating the DOD, there
    is no requirement for the Secretary of State to continue
    monitoring students for human rights abuses after they
    graduate from WHINSEC. In short, the statutes require the
    Secretary of State to take the lead in vetting foreign units
    receiving United States assistance, and the Secretary of
    Defense to consider information from the State Department
    before providing training or assistance to foreign military
    units, but not to continue such vetting after the assistance has
    concluded.
    4
    22 U.S.C. § 2378d(a) states: “No assistance shall be furnished under
    this chapter or the Arms Export Control Act to any unit of the security
    forces of a foreign country if the Secretary of State has credible
    information that such unit has committed a gross violation of human
    rights.”
    5
    The requirement that the Secretary of State “establish, and
    periodically update, procedures to . . . ensure that . . . the individual’s unit
    is vetted as well as the individual” was added to the statute on December
    23, 2011, see Consolidated Appropriations Act, 2012, Pub. L. 112-74,
    § 2378d, 125 Stat. 786, 1216 (2011), after the March 1, 2011 FOIA
    request in this case. The parties do not argue that this affects our analysis
    of the plaintiffs’ FOIA request for information about individual students
    and instructors at WHINSEC, and therefore we do not address this issue.
    8         CAMERANESI V. U.S. DEP’T OF DEFENSE
    B
    In conjunction with implementing these laws, Congress
    replaced SOA with a new training facility called the Western
    Hemisphere Institute for Security Cooperation (WHINSEC).
    See Floyd D. Spence National Defense Authorization Act for
    Fiscal Year 2001, Pub. L. No. 106-398, § 911, 114 Stat.
    1654A-226 (2000) (codified at 10 U.S.C. § 2166).
    WHINSEC, which opened its doors on January 17, 2001,
    provides “professional education and training to eligible
    personnel of nations of the Western Hemisphere.” 10 U.S.C.
    § 2166(b). Section 2166 states that one of the purposes of
    WHINSEC is “promoting . . . respect for human rights.” 
    Id. To accomplish
    this goal, Congress required that the
    WHINSEC curriculum “include mandatory instruction for
    each student, for at least 8 hours, on human rights, the rule of
    law, due process, civilian control of the military, and the role
    of the military in a democratic society.” 
    Id. § 2166(d)(1).
    To ensure that WHINSEC complies with its statutory
    obligations, Congress established an independent WHINSEC
    Board of Visitors charged with “inquir[ing] into the
    curriculum, instruction, physical equipment, fiscal affairs,
    and academic methods of [WHINSEC].” 
    Id. § 2166(e)(4)(A).
    Under this statute, the Board of Visitors must hold an annual
    public meeting and “submit to the Secretary of Defense a
    written report of its activities and of its views and
    recommendations pertaining to the Institute.”             
    Id. §§ 2166(e)(3),
    (5). Pursuant to these obligations, the Board
    of Visitors maintains an updated database containing details
    CAMERANESI V. U.S. DEP’T OF DEFENSE                       9
    on its annual meetings from 2002 to the present.6 The
    minutes reflect that the Board closely oversaw the
    development of WHINSEC’s human rights curriculum, see
    Board of Visitors WHINSEC, Minutes of Annual Meeting
    (Jun. 3–4, 2002),7 and ultimately concluded that WHINSEC
    “is a success story, in terms of its diligent pursuit of its
    mission of teaching professional military values, including
    human rights and democracy,” Board of Visitors WHINSEC,
    Minutes of Annual Meeting (Dec. 1–2, 2004).8 In executing
    its ongoing duty to monitor WHINSEC’s fulfillment of its
    human rights mission,9 the Board has formed a curriculum
    subcommittee which has “observed classes, reviewed selected
    lesson plans and reference material, and visited training
    facilities,” as well as interviewed students and faculty.

    WHINSEC had made “enormous strides in inserting human
    rights and democracy education into the curriculum, and is
    reported to have exceeded minimum required hours of
    instruction.” Memorandum from the Curriculum Review
    Sub-Committee, WHINSEC BoV, on Review of WHINSEC
    Curriculum (May 30, 2007) (Annex 3 in Sec’y of Def.,
    Annual Report to Cong. on the Activities of the Western
    Hemisphere Institute for Security Cooperation 25 (2007)).10
    Based on this report, the Board of Visitors concluded that
    WHINSEC “was meeting and in some cases exceeding its
    congressional mandate in the area of promoting human rights
    and democratic values.” Memorandum from Matthew D.
    Anderson & Robert C. Morlino, WHINSEC BoV, on

    (2007)).
    While the State Department, rather than WHINSEC, is
    responsible for vetting the individuals designated to attend
    the school, the Board has reviewed the vetting process in
    response to public comments. Letter from Ambassador Jose

    According to the Annual Report to Congress, WHINSEC’s human
    rights curriculum “consisted of nine integrated parts: Democracy and
    Human Rights Class, Democracy and Human Rights Week, the
    Intermediate Level Education (ILE) Electives, Human Rights Instructor
    Course, Engagement Skills Training Facility, Human Rights Subject
    Matter Expert Exchanges, Human Rights NGO Roundtables, and the Field
    Studies Program.” Sec’y of Def., Annual Report to Cong. on the

    2007) (Annex F in Sec’y of Def., Annual Report to Cong. on
    the Activities of the Western Hemisphere Institute for
    Security Cooperation (2006)). On one occasion, in response
    to charges by SOAW that “several alleged human rights
    violators had participated in WHINSEC programs,” the Board
    requested an investigation into the vetting process and
    reported that “effort and care” went into making the vetting
    process “rigorous, labor intensive, layered, and multi-
    agency.” 
    Id. at 1–2.11
    As part of its oversight effort, despite
    having neither funds nor legal authority “to follow the
    subsequent military careers of former [WHINSEC] students
    on an organized basis,” the Board of Visitors nevertheless
    employed analysts to conduct external evaluations, used a
    survey tool developed by the United States Southern
    Command, and made efforts through contacts in foreign
    countries to obtain ongoing information regarding former
    WHINSEC students. Board of Visitors WHINSEC, Minutes
    of Annual Meeting 4 (Dec. 1–2, 2004).
    Each report by the Board of Visitors is ultimately sent to
    the Secretary of Defense, who is then required to submit a
    detailed annual report to Congress. 10 U.S.C. § 2166(i). In
    its 2007 report, the Secretary noted that the “WHINSEC
    Democracy and Human Rights Program is a very successful
    and innovative program” that “is woven into every aspect of
    the curriculum.” Sec’y of Def., Annual Report to Cong. on
    the Activities of the Western Hemisphere Institute for

    selection process, the Secretary stated that after the

    activities that would render them ineligible or inappropriate

    Id. C The
    terrorist attacks of September 11, 2001, which
    occurred just nine months after WHINSEC began operations,
    heightened the DOD’s concerns regarding protecting its
    personnel. On November 9, 2001, the DOD issued a
    memorandum instructing all DOD components to “ordinarily
    withhold lists of names and other personally identifying
    information of personnel . . . in response to requests under the
    FOIA.” The memorandum also reemphasized the DOD’s
    longstanding policy of refusing to disclose identifying
    information of American service members. 5 U.S.C.
    § 552(b)(3). In 2006, the DOD promulgated regulations to
    formalize this policy, mandating that “Army components
    shall ordinarily withhold lists of names (including active duty
    military, civilian employees, contractors, members of the
    National Guard and Reserves, and military dependents) and
    other personally identifying information” in response to
    FOIA requests. 32 C.F.R. § 518.13(f)(2).
    The DOD’s November 9, 2001 memorandum regarding
    American military personnel did not immediately impact
    WHINSEC’s privacy policies.      The DOD continued
    disclosing the names of WHINSEC students and instructors
    through 2004, and SOAW incorporated each new set of
    CAMERANESI V. U.S. DEP’T OF DEFENSE                       13
    names into its database. SOAW’s database included some
    60,000 names, which it used to identify individuals who have
    allegedly engaged in human rights abuses.
    In 2005, however, the Army’s General Counsel
    determined that international personnel should be accorded
    the same right to privacy as U.S. personnel. Following this
    decision, the DOD ceased its annual public disclosure of
    WHINSEC students and instructors and began to redact the
    names of WHINSEC students from all publicly released
    documents. The DOD continued to comply with the Leahy
    Amendment requirements to disclose the names of
    WHINSEC students and instructors to Congress in a
    classified format. In 2010, Congress amended the National
    Defense Authorization Act to require the Secretary of
    Defense to “release to the public, upon request . . . the entire
    name . . . [of] each student and instructor at the Western
    Hemisphere Institute for Security Cooperation,” but the
    statute allowed the Secretary to “waive the [disclosure]
    requirement . . . if the Secretary determines it to be in the
    national interest.” National Defense Authorization Act for
    Fiscal Year 2010, Pub. L. No. 111-84, § 1083, 123 Stat. 2190,
    2482 (2009). The Secretary exercised his authority to waive
    disclosure in both 2009 and 2010. This disclosure
    requirement was not included in subsequent appropriations
    bills.12

    14        CAMERANESI V. U.S. DEP’T OF DEFENSE
    In March 2010, the House of Representatives Committee
    on Armed Services convened a hearing to receive testimony
    from U.S. Air Force General Douglas Fraser, Commander of
    the United States Southern Command, and U.S. Air Force
    General Victor Renuart, Jr., Commander of the North
    American Aerospace Defense Command. See Hearing on
    National Defense Authorization Act for Fiscal Year 2011 and
    Oversight of Previously Authorized Programs Before the H.
    Comm. on Armed Services, 111th Cong. 1 (2010). Among
    other issues, the generals addressed questions regarding a
    proposed amendment to the appropriations act that would
    authorize publication of personal information of WHINSEC
    students. General Fraser spoke against public disclosure of
    the names of WHINSEC students and urged Congress to
    respect the “rights and desires of the nations who provide
    [WHINSEC students]” by protecting their privacy. 
    Id. at 16.
    He further stated that disclosure would threaten the privacy
    of the United States citizen instructors and staff. 
    Id. General Renuart
    agreed with General Fraser regarding “the
    importance of maintaining the security of the individuals
    attending [WHINSEC], as well as the faculty.” 
    Id. In explaining
    the risks of disclosure, General Renuart described
    an event that, while not involving a WHINSEC attendee, was
    “an example of what can happen when information is in fact
    released.” 
    Id. The event
    involved the Mexican navy’s
    successful raid on Arturo Beltran Leyva, the alleged leader of
    a Mexican drug cartel. One of the naval officers involved in
    the raid was killed, and his name was subsequently released
    to the public. As a result, his mother, wife and children were
    killed. According to General Renuart, the DOD could not
    “afford to have the information that is held in WHINSEC
    released because it will have that kind of effect potentially for
    the individuals who are extremely valuable to us.” 
    Id. at 19.
    Accordingly, General Renuart advised the representatives that
    CAMERANESI V. U.S. DEP’T OF DEFENSE                15
    “we need to be very careful about the release of that
    information, and we would oppose that.” 
    Id. Congress ultimately
    decided not to include the disclosure requirement
    in the appropriations act.
    D
    On March 1, 2011, two members of SOAW, Theresa
    Cameranesi and Judith Liteky, sent a FOIA request to the
    DOD (specifically, the U.S. Army Training and Doctrine
    Command) for “the names, ranks, branches, countries of
    origin, lists of courses taken or taught, and/or dates and years
    of attendance of students, instructors, and guest instructors at
    [WHINSEC]” in fiscal years 2005 to 2010. A few weeks
    later, the plaintiffs amended their FOIA request to request
    information on the units of WHINSEC students and
    instructors. The DOD partially denied the request on April 5,
    2011. It disclosed some responsive records but withheld the
    names or units of WHINSEC attendees under FOIA
    Exemption 6. See 5 U.S.C. § 552(b)(6). The plaintiffs filed
    an administrative appeal, which the DOD denied on June 8,
    2011.
    Following the denial of their administrative appeal, the
    plaintiffs filed suit in district court, claiming that DOD
    violated FOIA by failing to disclose the requested records.
    The parties filed cross-motions for summary judgment. In its
    motion, the DOD argued that it was entitled to withhold the
    identifying information regarding students and instructors
    under Exemption 6 to FOIA, 5 U.S.C. § 552(b)(6), and
    submitted two affidavits from Lee A. Rials, the Public Affairs
    Specialist for WHINSEC, in support. Rials’s affidavits stated
    that “[t]here are a number of risks associated with releasing
    the names of WHINSEC students, instructors, and guest
    16          CAMERANESI V. U.S. DEP’T OF DEFENSE
    instructors,” because these students “are directly involved in
    conflicts with criminal gangs, drug cartels, and other violent
    individuals.” Rials then stated that assessments prepared by
    the Defense Intelligence Agency (which had not been
    approved for public release) “indicate that the public
    disclosure of WHINSEC’s records may increase the threat to
    Latin American students from: (1) the intelligence and
    security apparatuses of countries hostile to U.S. interests and
    to U.S. partner nations in the Western Hemisphere;
    (2) terrorist organizations operating in the Western
    Hemisphere; and (3) drug trafficking organizations operating
    in the Western Hemisphere.” As an example, Rials stated
    that in some countries “security personnel and their families
    have been attacked after being identified in the media,” and
    referenced the 2010 testimony of General Renuart before the
    House Armed Services Committee. Finally, Rials stated that
    foreign nations participating in the WHINSEC program
    opposed “public disclosure of personally identifying
    information of students and instructors” and that such
    disclosure “may have adverse effects on future participation
    in training programs at WHINSEC.”
    The district court granted summary judgment in favor of
    the plaintiffs. It held that DOD had not established that
    WHINSEC students and instructors had “a substantial privacy
    interest in their names” because they had not been promised
    confidentiality and their names had been routinely provided
    to the public before 2004.13 The DOD timely appealed.
    13
    The district court separately addressed the plaintiffs’ request for
    WHINSEC unit information in an order issued July 29, 2013. This issue
    is not before us.

    II
    In the past, we employed a standard unique to FOIA cases
    for reviewing a district court’s summary judgment. See
    Yonemoto v. Dep’t of Veterans Affairs, 
    686 F.3d 681
    , 688
    (9th Cir. 2011) (holding that in reviewing a grant of summary
    judgment in a FOIA case, we first review de novo whether
    there is an adequate factual basis to support the district
    court’s decision, and if there is, we then review the district
    court’s conclusions of fact for clear error). We have now
    overruled this FOIA-specific summary judgment standard,
    and instead apply our usual summary judgment standard. See
    Animal Legal Def. Fund v. U.S. Food & Drug Admin., No.
    13-17131, 
    2016 WL 4578362
    , at *2 (9th Cir. Sept. 2, 2016)
    (en banc). Accordingly, we now review the district court’s
    grant or denial of motions for summary judgment de novo.
    
    Id. “[W]e view
    the evidence in the light most favorable to the
    nonmoving party, determine whether there are any genuine
    issues of material fact, and decide whether the district court
    correctly applied the relevant substantive law.” 
    Id. at *1.
    “If
    there are genuine issues of material fact in a FOIA case, the
    district court should proceed to a bench trial or adversary
    hearing.” 
    Id. at *2.
    In this case, the facts are undisputed and
    the decision turns on the legal issue whether disclosure of the
    names of foreign students and instructors at WHINSEC
    “would constitute a clearly unwarranted invasion of personal
    privacy” for purposes of Exemption 6. 5 U.S.C. § 552(b)(6).
    We have jurisdiction to review the district court’s grant of
    summary judgment under 28 U.S.C. § 1291.
    III
    FOIA requires federal agencies to disclose records that
    are requested by a member of the public. 5 U.S.C. § 552.
    18          CAMERANESI V. U.S. DEP’T OF DEFENSE
    The statute provides that “each agency, upon any request for
    records which (i) reasonably describes such records and (ii)
    is made in accordance with published rules . . . and
    procedures to be followed, shall make the records promptly
    available to any person.” 
    Id. § 552(a)(3)(A).14
    FOIA’s
    disclosure obligations extend to all agency records except the
    nine categories of records listed in § 552(b) as exempt from
    disclosure. “[A]s a general rule, when documents are within
    FOIA’s disclosure provisions, citizens should not be required
    to explain why they seek the information” because
    information about government functions “belongs to citizens
    to do with as they choose.” Nat’l Archives & Records Admin.
    v. Favish, 
    541 U.S. 157
    , 172 (2004). But when disclosure
    affects the types of information protected by the exemptions,
    “the usual rule that the citizen need not offer a reason for
    requesting the information must be inapplicable.” 
    Id. At issue
    here is Exemption 6, which provides that FOIA
    “does not apply to . . . personnel and medical files and similar
    files the disclosure of which would constitute a clearly
    unwarranted invasion of personal privacy.” 
    Id. § 552(b)(6).
    In order to withhold information from disclosure under
    Exemption 6, the agency must specifically invoke the
    exemption and must carry the burden of proving that
    disclosure “would constitute a clearly unwarranted invasion
    of personal privacy.” See 
    Yonemoto, 686 F.3d at 693
    . A
    person requesting information protected by privacy interests
    “must show that the public interest sought to be advanced is
    a significant one, an interest more specific than having the
    14
    FOIA defines “agency” as “each authority of the Government of the
    United States, whether or not it is within or subject to review by another
    agency.” 5 U.S.C. § 551(1). There is no dispute that the DOD is an
    agency subject to FOIA.
    CAMERANESI V. U.S. DEP’T OF DEFENSE               19
    information for its own sake,” and must also show that “the
    information is likely to advance that interest.” 
    Favish, 541 U.S. at 172
    . “Otherwise, the invasion of privacy is
    unwarranted.” 
    Id. When evaluating
    an agency’s invocation of an exemption
    to FOIA, we “balance the public interest in disclosure against
    the interest Congress intended the [e]xemption to protect.”
    Dep’t of Def. v. Fed. Labor Relations Auth., 
    510 U.S. 487
    ,
    495 (1994). Our cases establish a two-step test for balancing
    individual privacy rights against the public’s right of access.
    First, we evaluate the personal privacy interest at stake to
    ensure “that disclosure implicates a personal privacy interest
    that is nontrivial or . . . more than [] de minimis.” 
    Yonemoto, 686 F.3d at 693
    (internal citation and quotation marks
    omitted). Second, if the agency succeeds in showing that the
    privacy interest at stake is nontrivial, we then “employ a
    balancing approach: We place the privacy interests identified
    at the first step on one end of the balance, and the public
    interest favoring disclosure on the other.” 
    Id. at 694.
    A
    We generally begin with an evaluation of the privacy
    interests at stake, which must be “some nontrivial privacy
    interest in nondisclosure.” Fed. Labor Relations 
    Auth., 510 U.S. at 501
    (emphasis omitted). A showing that the
    interest is more than de minimis will suffice. See Lahr v.
    Nat’l Transp. Safety Bd., 
    569 F.3d 964
    , 977 (9th Cir. 2009).
    “The personal privacy contemplated by Exemption 6, as well
    as its law-enforcement counterpart, Exemption 7(C), . . . is
    not some limited or cramped notion of that idea.” 
    Yonemoto, 686 F.3d at 693
    (internal citation and quotation marks
    20          CAMERANESI V. U.S. DEP’T OF DEFENSE
    omitted).15 Rather, a disclosure implicates personal privacy
    if it affects either “the individual’s control of information
    concerning his or her person,” Dep’t of Justice v. Reporters
    Comm. for Freedom of the Press, 
    489 U.S. 749
    , 763 (1989),
    or constitutes a “public intrusion[] long deemed
    impermissible under the common law and in our cultural
    traditions,” 
    Favish, 541 U.S. at 167
    .16
    Disclosures that would subject individuals to possible
    embarrassment, harassment, or the risk of mistreatment
    constitute nontrivial intrusions into privacy under Exemption
    6. See Dep’t of State v. Ray, 
    502 U.S. 164
    , 176–77 (1991);
    see also Forest Serv. Emps. for Envtl. Ethics v. U.S. Forest
    Serv., 
    524 F.3d 1021
    , 1025–28 (9th Cir. 2008); Painting
    Indus. of Haw. Mkt. Recovery Fund v. U.S. Dep’t of Air
    Force, 
    26 F.3d 1479
    , 1483 (9th Cir. 1994). In Ray, for
    instance, immigration attorneys made a FOIA request for the
    names of deported Haitian nationals who had been
    interviewed by the U.S. government to determine whether
    15
    Exemption 7(C) allows withholding “records or information
    compiled for law enforcement purposes, but only to the extent that the
    production of such law enforcement records . . . could reasonably be
    expected to constitute an unwarranted invasion of personal privacy.”
    5 U.S.C. § 552(b)(7)(C). As we explained in Yonemoto, because both
    Exemption 7(C) and Exemption 6 “require balancing the public interest
    with personal privacy, cases interpreting the interest in personal privacy
    with regard to one of the two exemptions are useful in the context of the
    
    other.” 686 F.3d at 693
    n.7 (internal quotation marks omitted). “If a
    nontrivial privacy interest is at stake, however, Exemption 7(C) requires
    a somewhat higher showing of public interest to overcome it than does
    Exemption 6.” 
    Id. 16 Although
    both Reporters Committee and Favish concern Exemption
    7(C), we have previously relied on them to define what makes a privacy
    interest “nontrivial.” See 
    Yonemoto, 686 F.3d at 693
    .
    CAMERANESI V. U.S. DEP’T OF DEFENSE               21
    they had been persecuted upon their return to 
    Haiti. 502 U.S. at 168
    –69. The Court rejected the plaintiffs’ argument that
    “any invasion of privacy from the mere act of disclosure of
    names and addresses would be de minimis and little more
    than speculation.” 
    Id. at 170
    (internal quotation omitted).
    Rather, the Court held that disclosing the interviewees’ names
    was a “significant invasion of their privacy” because it “could
    subject them or their families to embarrassment in their social
    and community relationships,” expose them “to possible
    embarrassment and retaliatory action,” or put them at “risk of
    mistreatment.” 
    Id. at 176–77
    & n.12 (internal quotation
    marks omitted).
    We have similarly held that the potential for harassment
    from third parties gives rise to a cognizable privacy interest.
    In Forest Service Employees, we considered a public interest
    group’s FOIA request for the names of 23 firefighters who
    had participated in fighting a wildfire in which two
    firefighters 
    died. 524 F.3d at 1023
    . We concluded that the
    employees had nontrivial privacy interests in the disclosure
    of their names because Exemption 6 protected against the
    “potential for harassment” that “would be presented by the
    media, curious neighbors, and the [public interest group]
    itself,” which might try to make unwanted contacts with the
    employees. 
    Id. at 1026.
    In so holding, we explained that
    “[t]he avoidance of harassment is a cognizable privacy
    interest under Exemption 6,” even when the harassment at
    issue is merely “unwanted commercial solicitations.” 
    Id. (citing Painting
    Indus., 26 F.3d at 1483
    ); see also Prudential
    Locations LLC v. U.S. Dep’t of Housing and Urban Dev.,
    
    739 F.3d 424
    , 432 (9th Cir. 2013). Similarly, Lahr noted that
    “protection from . . . unwanted contact [by third parties]
    facilitated by disclosure of a connection to government
    22        CAMERANESI V. U.S. DEP’T OF DEFENSE
    operations and investigations is a cognizable privacy interest”
    under Exemption 
    6. 569 F.3d at 976
    .
    An agency may carry its burden of establishing a
    nontrivial privacy interest by submitting affidavits showing
    that the requested disclosure has “[t]he potential” to result in
    the sorts of harassment described in our cases. 
    Lahr, 569 F.3d at 976
    . Although “a threat to privacy [that] is
    conceivable on some generalized conjectural level is not
    sufficient to justify invoking Exemption 6,” 
    Yonemoto, 686 F.3d at 694
    , “the invasion of a personal privacy interest
    may be ‘clearly unwarranted’ even when the invasion of
    privacy is far from a certainty,” Prudential 
    Locations, 739 F.3d at 432
    . The Supreme Court has relied on an
    agency’s reasonable assessment that disclosure “could
    subject” the affected individuals “to possible” invasion of
    privacy, 
    Ray, 502 U.S. at 176
    & n.12 (emphases added), and
    we have regularly done the same, see Prudential 
    Locations, 739 F.3d at 432
    (disclosure “would likely” result in an
    invasion of privacy); 
    Lahr, 569 F.3d at 977
    (disclosure
    “could” result in an invasion of privacy); Forest Serv. 
    Emps., 524 F.3d at 1026
    (disclosure “may” result in an invasion of
    privacy). Particularly in cases involving foreign policy and
    national security issues, “any affidavit or other agency
    statement of threatened harm to national security will always
    be speculative to some extent, in the sense that it describes a
    potential future harm.” ACLU v. U.S. Dep’t of Def., 
    628 F.3d 612
    , 619 (D.C. Cir. 2011) (internal quotation marks omitted).
    Therefore, an agency carries its burden if the affidavit
    provides a justification for invoking a FOIA exemption that
    “appears logical or plausible.” 
    Id. (internal quotation
    marks
    omitted).
    CAMERANESI V. U.S. DEP’T OF DEFENSE                23
    B
    If the agency succeeds in showing a nontrivial privacy
    interest at step one, we then proceed to step two. At this step,
    we balance the individual’s right of privacy against the public
    interest in disclosure.
    For purposes of FOIA, the pertinent public interest is the
    interest in understanding “the operations or activities of the
    government” and in monitoring an agency’s action. Forest
    Serv. 
    Emps., 524 F.3d at 1025
    –27. Said otherwise, “the only
    relevant public interest in the FOIA balancing analysis is the
    extent to which disclosure of the information sought would
    she[d] light on an agency’s performance of its statutory duties
    or otherwise let citizens know what their government is up
    to.” 
    Yonemoto, 686 F.3d at 694
    (quoting Bibles v. Or. Nat.
    Desert Assn., 
    519 U.S. 355
    , 355–56 (1997) (per curiam)).
    We do not give weight to the FOIA requester’s personal
    interest in obtaining information “[b]ecause Congress clearly
    intended the FOIA to give any member of the public as much
    right to disclosure as one with a special interest.” Fed. Labor
    Relations 
    Auth., 510 U.S. at 496
    (internal quotation marks
    omitted).
    In order to determine the weight of the public interest at
    issue, we must evaluate whether the person requesting the
    information has shown “sufficient reason for the disclosure.”
    
    Favish, 541 U.S. at 172
    . Favish developed a standard for
    determining whether a requester has shown such a reason in
    cases where the requester is seeking information “to show
    that responsible officials acted negligently or otherwise
    improperly in the performance of their duties.” 
    Id. at 174.
    Although noting that there is generally a “presumption of
    legitimacy accorded to the Government’s official conduct,”
    24          CAMERANESI V. U.S. DEP’T OF DEFENSE
    and “clear evidence is usually required to displace” that
    presumption, Favish adopted a less stringent standard in the
    FOIA context: “the requester must produce evidence that
    would warrant a belief by a reasonable person that the alleged
    Government impropriety might have occurred.”                
    Id. Although it
    is easier for a requester to meet this “reasonable
    belief” standard than a “clear evidence” standard, a court
    must still “insist on a meaningful evidentiary showing” by the
    requester because “[a]llegations of government misconduct
    are easy to allege and hard to disprove.” 
    Id. at 175.
    “Only
    when the FOIA requester has produced evidence sufficient to
    satisfy this standard will there exist a counterweight on the
    FOIA scale for the court to balance against the cognizable
    privacy interests in the requested records.” 
    Id. at 174–75.17
    17
    Contrary to the dissent’s implication, Favish’s holding is not
    limited to cases where the FOIA request seeks “materials related to the
    alleged mishandling of an investigation into one isolated incident.”
    Dissent at 42. In Associated Press v. U.S. Dep’t of Def., for instance, the
    Second Circuit considered a FOIA request for detainee-identifying
    information in the records of DOD’s investigation of allegations of
    detainee abuse at Guantanamo Naval Bay. 
    554 F.3d 274
    (2nd Cir. 2009).
    In response to the requester’s public interest argument that the information
    was needed to determine whether DOD “responded differently to
    allegations of abuse depending on the nationalities or religions of the
    abused detainees,” the court held that the argument was “squarely
    foreclosed by Favish,” because “there is no evidence of government
    impropriety in that regard.” 
    Id. at 289;
    see also Union Leader Corp. v.
    U.S. Dep’t of Homeland Sec., 
    749 F.3d 45
    , 56 (1st Cir. 2014) (holding that
    there was a public interest in disclosing the identities of arrested aliens to
    determine whether the government had been negligent in handling its
    removal duties, because evidence that the “aliens . . . had been convicted
    of crimes and/or ordered removed from the United States as long as 23
    years before their 2011 arrests” was “at least enough to warrant a
    reasonable belief ‘that the alleged Government impropriety might have
    occurred’”) (quoting 
    Favish, 541 U.S. at 174
    ). Indeed, Favish stated that
    it intended to give courts general direction for balancing categories of
    CAMERANESI V. U.S. DEP’T OF DEFENSE                          25
    Even when the requester’s evidence has met the standard
    of showing “more than a bare suspicion” that responsible
    officials acted negligently, 
    id. at 174,
    the requester must still
    show that “the requested information is likely to advance” a
    significant public interest, 
    id. at 172.
    Consequently, if the
    information sought does not “add significantly to the already
    available information concerning the manner in which [the
    agency] has performed its statutory duties,” we do not give
    the public interest much weight. Prudential 
    Locations, 739 F.3d at 433
    . When the FOIA requester seeks information
    about whether an agency properly performed a statutory duty,
    and the government has already investigated this issue and
    revealed information relating to its investigation, we deem the
    public interest in obtaining additional information to be less
    weighty unless the “marginal additional usefulness of [the
    sought] information” is significant. See Forest Serv. 
    Emps., 524 F.3d at 1027
    –28.
    IV
    We now apply this two-step test to determine whether
    disclosing the names of foreign WHINSEC students and
    instructors “would constitute a clearly unwarranted invasion
    of personal privacy” for purposes of Exemption 6. 5 U.S.C.
    § 552(b)(6).
    privacy interests against categories of public interest, so that courts would
    not be “left to balance in an ad hoc manner with little or no real 
    guidance.” 541 U.S. at 173
    . Here, the public interest asserted falls within the same
    category as the public interest at issue in Favish: in both cases, there is a
    public interest in the question whether “responsible officials acted
    negligently or otherwise improperly in the performance of their duties.”
    
    Id. at 174.
    26        CAMERANESI V. U.S. DEP’T OF DEFENSE
    A
    We first consider whether disclosure of the names and
    units of foreign WHINSEC students and instructors
    implicates a nontrivial privacy interest. See 
    Yonemoto, 686 F.3d at 693
    . We give little weight to the district court’s
    ruling that DOD failed to establish that WHINSEC students
    and instructors had “a substantial privacy interest in their
    names and military units” because the district court applied
    the wrong legal standard; it should have considered whether
    nontrivial privacy interests, rather than substantial privacy
    interests, were at stake.
    Here, the evidence submitted by the DOD demonstrated
    that disclosure of the identities of foreign WHINSEC students
    and instructors could give rise to harassment, stigma, or
    violence as a result of their association with the United
    States—exactly the sorts of risks that courts have recognized
    as nontrivial in previous cases. See 
    Ray, 502 U.S. at 176
    –77;
    
    Lahr, 569 F.3d at 975
    –76; Forest Serv. 
    Emps., 524 F.3d at 1025
    –28; Painting 
    Indus., 26 F.3d at 1483
    . The DOD
    submitted sufficient evidence to substantiate this nontrivial
    risk, see Lewis v. IRS, 
    823 F.2d 375
    , 378 (9th Cir. 1987),
    including Rials’s affidavits and the testimony of two United
    States generals.
    The plaintiffs argue that the evidence of risks faced by the
    WHINSEC students and instructors should be disregarded as
    overly speculative. We disagree. We have never held that an
    agency must document that harassment or mistreatment have
    happened in the past or will happen in the future; rather, the
    agency must merely establish that disclosure would result in
    a “potential for harassment.” Forest Serv. 
    Emps., 524 F.3d at 1026
    . Here, the government’s affidavits set forth its
    CAMERANESI V. U.S. DEP’T OF DEFENSE              27
    conclusion that foreign military and law enforcement
    personnel who are publicly associated with the United States
    could be subject to mistreatment or attack. See 
    Ray, 502 U.S. at 176
    . The same concerns rationally underlay the DOD’s
    decision to protect the identity of U.S. law enforcement and
    military personnel from FOIA requests. See 32 C.F.R.
    § 518.13(f)(2); see also 32 C.F.R. § 286.12(f)(2) (providing
    that DOD will not disclose the “names and duty addresses” of
    United States “military and civilian personnel who are
    assigned to units that are sensitive, routinely deployable, or
    stationed in foreign territories” because such disclosure “can
    constitute a clearly unwarranted invasion of personal
    privacy”). Because the government’s determination that
    foreign law enforcement and military personnel would face
    similar risks if their identities were revealed is logical and
    plausible, it is sufficient to establish that WHINSEC students
    and instructors have a nontrivial privacy interest. See ACLU
    v. Dep’t of 
    Def., 628 F.3d at 619
    ; see also Prudential
    
    Locations, 739 F.3d at 432

    Lahr, 569 F.3d at 977
    ; Forest
    Serv. 
    Emps., 524 F.3d at 1026
    .
    The district court also erred in holding that the
    WHINSEC students and instructors lacked a nontrivial
    privacy interest because the DOD had not promised
    confidentiality. As a legal matter, “an assurance of
    confidentiality from the government” is not a necessary
    condition “for the existence of a cognizable personal privacy
    interest under Exemption 6.” Prudential 
    Locations, 739 F.3d at 431
    –32. Moreover, the court’s conclusion that WHINSEC
    students and instructors do not have a reasonable expectation
    of privacy is not supported by the record. The DOD has not
    disclosed the names of WHINSEC students since 2004 and
    likewise redacts the names of WHINSEC students from
    public documents. Any disclosures are now made only with
    28        CAMERANESI V. U.S. DEP’T OF DEFENSE
    the consent of the students or the sending nation. A majority
    of foreign countries that send students to WHINSEC rely on
    the DOD’s current disclosure practices and oppose public
    disclosure of the identities of their students and instructors.
    Further, the DOD exercised its discretion to ensure that no
    disclosures would be made in response to Congress’s
    requirement that the DOD disclose the names of WHINSEC
    students in 2009 and 2010, and Congress chose not to reenact
    this requirement. Under these circumstances, students and
    instructors at WHINSEC could reasonably conclude that their
    identities would not be disclosed without their permission.
    Accordingly, we conclude that the affidavits and other
    evidence submitted by the DOD are sufficient to carry the
    DOD’s burden to establish that disclosure of the requested
    information gives rise to a nontrivial risk of harassment and
    mistreatment.
    B
    At step two, we balance the privacy interests identified at
    the first step against the public interest favoring disclosure.
    In order to conduct this balancing, we begin by identifying
    the public interest at issue, focusing on the “only relevant
    public interest under Exemption 6,” which is “the extent to
    which the information sought would she[d] light on an
    agency’s performance of its statutory duties or otherwise let
    citizens know what their government is up to.” Forest Serv.
    
    Emps., 524 F.3d at 1027
    (internal quotation marks omitted).
    The plaintiffs argue that their request for the identities of
    the WHINSEC students and instructors bears directly on two
    statutory duties of the DOD. First, the DOD is required to
    deny assistance, including WHINSEC training, to any “unit
    CAMERANESI V. U.S. DEP’T OF DEFENSE                     29
    of a foreign security force if the Secretary of Defense has
    credible information that the unit has committed a gross
    violation of human rights.” 10 U.S.C. § 2249e(a). Second,
    plaintiffs argue that the DOD must “ensure that when an
    individual is designated to receive United States training,
    equipment, or other types of assistance [including WHINSEC
    training] the individual’s unit is vetted as well as the
    individual.” 22 U.S.C. § 2378d(d)(5). But this second
    statutory obligation is imposed only on the Secretary of State,
    who was not the recipient of the plaintiffs’ FOIA request, and
    Congress assigned the DOD only the correlative obligation to
    consult with the State Department regarding information on
    units that have committed human rights violations. 10 U.S.C.
    § 2249e(a). Nevertheless, we will assume for the sake of
    argument that the DOD’s obligation to consult with the State
    Department is analogous to the State Department’s obligation
    to screen potential students at WHINSEC, and that both
    obligations are meant to ensure that members of a foreign
    security unit that has engaged in human rights abuses (and by
    extension, individuals who have themselves engaged in
    human rights violations) are not allowed to participate in
    WHINSEC training.
    Plaintiffs contend that obtaining the identities of the
    WHINSEC students and instructors will allow them to
    discover deficiencies in the vetting process, and they submit
    an affidavit identifying two instances where the Secretary of
    State mistakenly allowed individuals who had allegedly
    participated in human rights abuses to attend the school.18
    18
    One individual allegedly commanded a unit that beat and shot 16
    members of an indigenous organization in 1983 and then was allowed to
    attend WHINSEC in 2003. A second individual was allegedly responsible
    for the kidnapping and torture of a human rights organizer in 1997 and
    30         CAMERANESI V. U.S. DEP’T OF DEFENSE
    Although we agree there is a public interest in identifying
    even isolated instances of government error in performing its
    statutory duties, we deem the interest to be small in this
    context. Even assuming SOAW has identified two errors
    among the thousands of students that trained at WHINSEC
    from 2001 through 2004, this does not amount to a
    “meaningful evidentiary showing” that “responsible officials
    acted negligently or otherwise improperly in the performance
    of their duties.” 
    Favish, 541 U.S. at 174
    . Moreover,
    information regarding the effectiveness of the Department of
    State’s procedures for vetting prospective trainees is available
    to the public through the Board of Visitors’ public reports.
    See 10 U.S.C. § 2166(e)(5). Given the ongoing governmental
    review of DOD compliance and the absence of a meaningful
    showing of noncompliance, the disclosure of the names of all
    students and instructors at WHINSEC would not have
    significant “marginal additional usefulness,” Forest Serv.

    –28, or contribute “significantly to
    public understanding of the operations or activities of the
    government,” Fed. Labor Relations 
    Auth., 510 U.S. at 495
    (emphasis omitted).
    Second, plaintiffs contend that they can use the names of
    WHINSEC students to track their conduct after they have
    received their training. According to plaintiffs, if WHINSEC
    attendees violate human rights once they return to their
    service in foreign governments, it shows that WHINSEC
    human rights training is not effective. We disagree. While
    Congress required WHINSEC to provide mandatory
    instruction on human rights, § 2166(d)(1), the reports from
    then attended WHINSEC in 2002. SOAW also points to three students
    who attended WHINSEC while under official investigation for corruption,
    which is not alleged to be a human rights abuse.
    CAMERANESI V. U.S. DEP’T OF DEFENSE               31
    the Board of Visitors and Secretary of Defense make clear
    that WHINSEC is exceeding congressional requirements in
    this area. The Board of Visitors regularly monitors, reports
    on, and makes recommendations for improvements to
    WHINSEC’s curriculum. 10 U.S.C. § 2166(e)(4)(A); see
    also Memorandum from Matthew D. Anderson & Robert C.
    Morlino, WHINSEC BoV, on Curriculum Review of
    WHINSEC (July 13, 2007) (Annex 3 in Sec’y of Def.,
    Annual Report to Cong. on the Activities of the Western
    Hemisphere Institute for Security Cooperation 19 (2007)).
    The relationship between WHINSEC’s obligation to provide
    human rights training to WHINSEC students and the
    subsequent conduct of foreign law enforcement or military
    personnel, perhaps years after their training at WHINSEC, is
    tenuous at best. Even if individual attendees are later alleged
    to engage in human rights abuses, such subsequent incidents
    are unlikely to shed light on what the government is currently
    “up to” at WHINSEC. 
    Yonemoto, 686 F.3d at 694
    . Given the
    Board of Visitors’s responsibility for monitoring and
    reporting on WHINSEC’s curriculum, the disclosure of the
    names of all foreign students and instructors at WHINSEC
    would not “add significantly to the already available
    information concerning the manner in which [the agency] has
    performed its statutory duties,” Prudential 
    Locations, 739 F.3d at 433
    , or “appreciably further the public’s right to
    monitor the agency’s action,” Forest Serv. 
    Emps., 524 F.3d at 1027
    . The Supreme Court has ruled that the purposes of
    FOIA are not fostered by disclosure of information about
    private individuals that “reveals little or nothing about an
    agency’s own conduct.” Reporters Comm. for Freedom of
    
    Press, 489 U.S. at 773
    .
    Having defined the public interest at stake, we now weigh
    it against the privacy interest of the WHINSEC students and
    32        CAMERANESI V. U.S. DEP’T OF DEFENSE
    instructors. DOD has presented evidence that disclosing the
    names of WHINSEC students and instructors would put them
    at risk of harassment, retaliation, or even death. Where
    serious privacy risks are present on one side of the balance,
    strong public interests are required in order to tip the scales
    toward disclosure. Forest Serv. 
    Emps., 524 F.3d at 1027
    .
    Because any incremental value stemming from the disclosure
    of the identities of WHINSEC students and instructors is
    small, the public interest in this case is not significant
    compared to the risk of disclosure. We therefore conclude
    that disclosure would give rise to a “clearly unwarranted”
    invasion of privacy and that the information requested by
    plaintiffs is exempt from disclosure under Exemption 6 of
    FOIA.
    The dissent disagrees with our application of the FOIA
    balancing test because it is not persuaded by the
    government’s reasons for instituting a new policy to withhold
    the names of students and instructors in 2005. The dissent
    argues that because the DOD disclosed the names of SOA
    and WHINSEC students and instructors until 2004, it must
    “provide a satisfactory explanation” for its change in policy
    in order to invoke Exemption 6. Dissent at 45.
    The dissent’s analysis is wrong for several reasons. Most
    important, FOIA does not impose a duty on the government
    to provide a satisfactory explanation of a change in its policy;
    rather, it merely requires us to decide on the record before us
    whether disclosure of the requested information would give
    rise to a “clearly unwarranted” invasion of privacy. 5 U.S.C.
    § 552(b)(6). Here, the government’s assertion that disclosure
    would do so is both logical and plausible. Applying simple
    common sense, there is no question that there are many
    groups in foreign countries that would seek to harm those
    CAMERANESI V. U.S. DEP’T OF DEFENSE                       33
    who are publicly associated with the United States military.
    And it is equally plausible that the risks facing WHINSEC
    students and instructors are sufficient to justify withholding
    under Exemption 6. Even the dissent concedes that these
    risks are real. Dissent at 34, 45.
    But even if we were to evaluate the government’s
    explanation of its policy decision, we disagree with the
    dissent’s view that the government did “not provide a
    satisfactory explanation.” Dissent at 45. The government
    explained that the DOD circulated an internal memorandum
    changing its policies regarding disclosure of the names of
    defense personnel two months after the terrorist attacks of
    September 11, 2001, and realized that international personnel
    should be accorded the same protection some years later. In
    our view, a government bureaucracy’s failure to demonstrate
    speed and efficiency in applying a policy issued in one
    context to a related but different context does not raise the
    inference that the government is hiding the true reasons for
    that policy. Indeed, it took the DOD five years to formalize
    its policy regarding American military personnel after it
    circulated its informal memo. See 32 C.F.R. § 518.13(f)(2);
    see also The Freedom of Information Act Program, 71 Fed.
    Reg. 9222, 9232 (Feb. 22, 2006).19
    19
    The dissent also speculates that the threats facing WHINSEC
    students and instructors were “undoubtedly” present during the decade
    from 1994 to 2004, and so infers that it would be unreasonable for the
    government to change its nondisclosure policy starting in 2005. Dissent
    at 45. There is no support in the record for this speculation, and it is
    equally likely that escalating violence influenced the government’s
    decision to change its nondisclosure policy in 2005. See, e.g., Mary
    Jordan & Kevin Sullivan, Border Police Chief Only Latest Casualty in
    Mexico Drug War, Wash. Post, June 16, 2005 (reporting on Mexico’s
    “worst barrage of drug-related violence in years” and noting that an
    34          CAMERANESI V. U.S. DEP’T OF DEFENSE
    Because disclosing the names of WHINSEC students and
    instructors would give rise to a “clearly unwarranted”
    invasion of privacy, those names are therefore exempt from
    disclosure under Exemption 6 of FOIA.
    REVERSED.
    WATFORD, Circuit Judge, dissenting:
    The Department of Defense has shown that the Western
    Hemisphere Institute for Security Cooperation’s foreign
    students and instructors have a non-trivial privacy interest in
    keeping their identities secret. Disclosing their names to the
    public would reveal their affiliation with the Institute, which
    might expose them to the risk of harassment or violence when
    they return to their home countries. But the question remains
    under Exemption 6 of the Freedom of Information Act
    (FOIA) whether that invasion of privacy would be “clearly
    unwarranted.” 5 U.S.C. § 552(b)(6). To answer that
    question, we must balance the privacy interests at stake
    against the public interest in disclosure protected by
    FOIA—namely, “the citizens’ right to be informed about
    ‘what their government is up to,’” which encompasses
    “[o]fficial information that sheds light on an agency’s
    “increasing number” of victims of drug violence are “public servants” who
    “stood up to organized crime”); Ginger Thompson & James C. McKinley,
    Jr., Mexico’s Drug Cartels Wage Fierce Battle for Their Turf, N.Y. Times,
    Jan. 14. 2005 (noting that while in “the last four years” Mexico had made
    advances in its fight against drug cartels, a new wave of drug related
    killings showed that cartel leaders had begun to regroup, and noting that
    at least 34 people, including three federal agents and two journalists, had
    been assassinated in the last six months of 2004).

    performance of its statutory duties.” Department of Justice
    v. Reporters Committee for Freedom of the Press, 
    489 U.S. 749
    , 773 (1989). In my view, on the thin evidentiary record
    presented here, the Department of Defense did not carry its
    burden of demonstrating that the students’ and instructors’
    privacy interests outweigh the strong public interest in
    disclosure of their names.
    I
    Let’s start with the public interest in disclosure, which
    requires a little bit of background. The Institute is operated
    by the Army at Fort Benning, Georgia. It was established in
    2001, but it is actually a continuation of the School of the
    Americas (SOA), which opened its doors under a different
    name in 1946 and moved to Fort Benning in the 1980s. SOA
    became the subject of considerable controversy after the 1989
    massacre of six Jesuit priests in El Salvador during that
    country’s civil war. It turned out that 19 of the soldiers
    involved in the massacre had received training at SOA.
    That incident was not an anomaly. After the Army began
    releasing the names of former SOA students and instructors
    in 1994 as a result of FOIA requests, human rights activists
    linked the school’s attendees to a host of notorious crimes. A
    few examples: SOA graduates were implicated in additional
    atrocities committed during the civil war in El Salvador,
    including the assassination of Archbishop Oscar Romero, the
    execution of four American churchwomen, and the massacre
    of hundreds of civilians in the village of El Mozote. A
    Guatemalan colonel who attended SOA was accused of
    murdering, six months after graduating, an American
    innkeeper in Guatemala in 1990. Six Peruvian SOA
    graduates were connected to the killings of nine students and
    36        CAMERANESI V. U.S. DEP’T OF DEFENSE
    a professor in Peru in 1992. In addition, SOA counted among
    its alumni Salvadoran death-squad leader Roberto
    D’Aubuisson; Bolivian strongman Hugo Banzer Suarez;
    Panamanian dictator and convicted drug-trafficker Manuel
    Noriega; Argentine dictators and “dirty war” culprits Roberto
    Viola and Leopoldo Galtieri; and Ecuador’s Guillermo
    Rodriguez and Peru’s Juan Velasco Alvarado, both of whom
    toppled democratically elected governments. See H.R. 732,
    106th Cong. (1999); Richard F. Grimmett & Mark P.
    Sullivan, Congressional Research Service, U.S. Army School
    of the Americas: Background and Congressional Concerns
    3–4 (2001); Eric Schmitt, School for Assassins, or Aid to
    Latin Democracy?, N.Y. Times, Apr. 3, 1995, at A8.
    The Army cautioned, rightly, that these incidents were not
    representative of the vast majority of SOA attendees,
    although it did not disclaim them entirely. A spokesman for
    the school responded to the criticism in 1995 by observing
    that “[o]ut of 59,000 students who have graduated from a
    variety of programs, less than 300 have been cited for human
    rights violations like torture and murder, and less than 50
    have been convicted of anything.” Schmitt, School for
    Assassins, at A8. However, the controversy escalated in 1996
    when the Pentagon released excerpts of training manuals
    previously used at SOA that provided instruction on torturing
    and executing insurgents. See Dana Priest, U.S. Instructed
    Latins on Executions, Torture, Wash. Post, Sept. 21, 1996, at
    A1.
    In 1997, Congress began imposing legislative restrictions
    on the school’s operations. It enacted what became known as
    the Leahy Amendment, which barred the military from
    assisting any foreign security unit credibly believed to have
    committed human rights abuses unless that unit’s government
    CAMERANESI V. U.S. DEP’T OF DEFENSE                37
    had taken steps to bring the responsible parties to justice. See
    Foreign Operations, Export Financing, and Related Programs
    Appropriations Act for Fiscal Year 1998, Pub. L. No. 105-
    118, § 570, 111 Stat. 2386, 2429 (1997). Congress also
    barred funding for SOA unless the Secretary of Defense
    certified that the training provided at the school was
    consistent with that provided to U.S. personnel at other
    military institutions, “particularly with respect to the
    observance of human rights.” 
    Id. at 2401.
    The intended
    effect of these provisions was to preclude Latin American
    military and law-enforcement personnel from attending SOA
    if their units had engaged in past human rights abuses, and to
    ensure that the school’s attendees were not trained in ways
    that might contribute to human rights abuses after they
    returned to their home countries. The Leahy Amendment and
    the certification requirement did not quiet the outcry over
    SOA. In 1999, the House of Representatives passed an
    amendment by a vote of 230–197 that would have closed
    SOA altogether. See 145 Cong. Rec. 18716–26, 18737
    (1999).
    In response to this congressional action, the Army
    pledged curricular changes and increased civilian
    participation at the school, and these proposed changes
    succeeded in staving off the school’s closure. In 2000, rather
    than close SOA, Congress decided to impose reform
    measures. Congress required the school to include instruction
    for all students on respect for human rights and principles of
    democratic governance, and mandated oversight of the school
    by a Board of Visitors composed primarily of civilians and
    civilian-designees. See National Defense Authorization Act
    for Fiscal Year 2001, Pub. L. No. 106-398, § 911, 114 Stat.
    1654, 1654A-226–28 (2000) (codified at 10 U.S.C. § 2166).
    To avoid association with SOA’s controversial past, it was
    38        CAMERANESI V. U.S. DEP’T OF DEFENSE
    thought best to rename the school going forward. Beginning
    in early 2001, the school began operating under its new name:
    the Western Hemisphere Institute for Security Cooperation.
    That background is relevant to understanding the strength
    of the public interest in disclosure involved here. Disclosing
    the names of the Institute’s foreign students and instructors is
    necessary to allow citizens to remain informed about “what
    their government is up to.” For example, without the names,
    the public has no way of determining whether the issues that
    led to the school’s near closure have been adequately
    addressed. Is the Army in fact barring attendance of foreign
    military and law-enforcement personnel who belong to units
    with records of human rights abuses? Or are such individuals
    continuing to receive training at the Institute at taxpayer
    expense? Have the new curricular requirements been
    effective in instilling the importance of respect for human
    rights and democratic values? Or are students trained at the
    Institute continuing to commit human rights abuses upon
    returning to their home countries? These are not idle
    questions given the school’s checkered history. Because the
    Institute remained in operation only after Congress mandated
    reforms designed to fix the problems that formerly plagued
    the school, the public has a strong ongoing interest in
    assessing whether those measures are working.
    Beyond advancing this more general interest, disclosing
    the names of the Institute’s foreign students and instructors
    would also shed light on how well the Departments of
    Defense and State are performing their statutory duties. See
    Reporters 
    Committee, 489 U.S. at 773
    . Under the current
    version of the Leahy Amendment, the government may not
    train, equip, or otherwise assist any “unit” of a foreign
    security force if the unit has committed “a gross violation of
    CAMERANESI V. U.S. DEP’T OF DEFENSE                39
    human rights.” 10 U.S.C. § 2249e(a)(1); 22 U.S.C.
    § 2378d(a). This restriction imposes specific duties upon the
    Departments of Defense and State. The Defense Department
    is expressly barred from spending funds on the proscribed
    foreign assistance, and prior to aiding a foreign security unit,
    the Secretary of Defense must consult with the Secretary of
    State regarding “any credible information available to the
    Department of State relating to human rights violations by
    such unit.” 10 U.S.C. § 2249e(a). In turn, the Secretary of
    State must “ensure that when an individual is designated to
    receive United States training, equipment, or other types of
    assistance the individual’s unit is vetted as well as the
    individual.” 22 U.S.C. § 2378d(d)(5). Disclosure of the
    names of the Institute’s foreign students would allow the
    public to assess the State Department’s performance of its
    vetting functions, as well as the Defense Department’s
    performance of its duty to consult with the State Department
    and to refrain from training any units with suspect human
    rights records.
    II
    The strength of the public interest in disclosure is what
    distinguishes this case from the cases on which the
    Department of Defense relies to justify its invocation of
    Exemption 6. In those cases, the courts struck the balance in
    favor of protecting privacy interests because the public
    interest in disclosure was either non-existent or exceptionally
    weak.
    In the first set of cases, there was simply no cognizable
    public interest in disclosure at all. See Bibles v. Oregon
    Natural Desert Association, 
    519 U.S. 355
    , 355–56 (1997)
    (per curiam); Department of Defense v. FLRA, 
    510 U.S. 487

    Committee, 489 U.S. at 774
    –75.
    The requested information revealed “little or nothing” about
    the relevant government agencies or their activities, and
    therefore could not “appreciably further the citizens’ right to
    be informed about what their government is up to.” 
    FLRA, 510 U.S. at 497
    (internal quotation marks omitted). For the
    reasons just explained, the same cannot be said about the
    information requested by the plaintiffs in this case.
    In the second set of cases, the courts held that although a
    cognizable public interest in disclosure existed, it was
    adequately served by the wealth of information the
    government had already made publicly available. See
    Department of State v. Ray, 
    502 U.S. 164
    , 178 (1991);
    Prudential Locations LLC v. HUD, 
    739 F.3d 424
    , 433 (9th
    Cir. 2013) (per curiam); Forest Service Employees for
    Environmental Ethics v. U.S. Forest Service, 
    524 F.3d 1021
    ,
    1028 (9th Cir. 2008). In those cases, obtaining the additional
    information sought by the requesters (the names of particular
    individuals) would not have shed any light on the operations
    or activities of the government. Here, by contrast, without
    obtaining the foreign students’ and instructors’ names, the
    public cannot exercise its right to remain informed about the
    Army’s operation of the Institute or assess how well the
    Departments of State and Defense are performing their
    statutory duties.
    The majority asserts that annual reports produced by the
    Institute’s Board of Visitors, as well as those issued by the
    Department of Defense itself, are adequate for these purposes,
    see Maj. op. at 30, 30–31, 31, but in truth the reports are
    utterly useless in this regard. They merely provide general
    conclusions about the Army’s operation of the Institute and
    the government’s vetting of its attendees, not the underlying
    CAMERANESI V. U.S. DEP’T OF DEFENSE                   41
    information necessary to determine whether those
    conclusions are correct.1 Without knowing the actual names
    of those allowed to attend the Institute, the public has no way
    of independently verifying whether students are properly
    vetted before enrolling at the Institute, or whether after
    graduating they engage in human rights abuses in their home
    countries. As the majority would have it, the public must
    simply take the government’s word for it that the reform
    measures mandated by Congress have been effective. This
    fox-guarding-the-henhouse notion is, of course, completely
    antithetical to FOIA’s core purpose.
    Finally, in the last set of cases, the requesters alleged that,
    in the course of investigating an isolated incident, the
    government had either engaged in a cover-up or conducted an
    insufficiently thorough investigation. See National Archives
    and Records Administration v. Favish, 
    541 U.S. 157
    , 160–61
    (2004) (requester alleged that Vince Foster’s death was not
    actually a suicide); Lahr v. National Transportation Safety
    Board, 
    569 F.3d 964
    , 969 (9th Cir. 2009) (requester alleged
    that TWA Flight 800 did not crash; it was shot down by the
    military); Lane v. Department of the Interior, 
    523 F.3d 1128
    ,
    1131–33 (9th Cir. 2008) (requester alleged that her former
    supervisor had in fact threatened a fellow employee with a
    gun, contrary to the conclusion reached by investigators). In
    that narrow context, when the asserted public interest rests on
    showing that “the investigative agency or other responsible
    officials acted negligently or otherwise improperly in the
    performance of their duties,” the requester must produce at
    least some evidence of government impropriety to

    substantiate the public interest claim. 
    Favish, 541 U.S. at 173
    –74.
    The majority’s reliance on this last set of cases is
    misplaced for two reasons. First, the standard established in
    those cases does not apply here. The plaintiffs are not
    seeking materials related to the alleged mishandling of an
    investigation into one isolated incident, the only context in
    which the Supreme Court and our court have applied the
    Favish standard. Rather, they are seeking information
    relevant to assessing government activities of a programmatic
    nature, a context in which the Supreme Court has held that a
    strong public interest in disclosure exists without any
    showing of government impropriety. See Department of the
    Air Force v. Rose, 
    425 U.S. 352
    , 368 (1976). But even under
    the majority’s reading of Favish, the standard established in
    that case does not apply here because the plaintiffs are not
    merely seeking “information about whether an agency
    properly performed a statutory duty.” Maj. op. at 25. They
    are also seeking information necessary to determine whether
    students who attend the Institute commit human rights abuses
    or other misconduct after returning to their home countries.
    As the majority itself acknowledges, that interest is in no way
    tied to the narrower interest in determining whether
    “responsible officials acted negligently or otherwise
    improperly in the performance of their duties.” Maj. op. at 25
    n.17 (quoting 
    Favish, 541 U.S. at 174
    ), 30.
    Second, even if the plaintiffs were required under Favish
    to make a threshold evidentiary showing, they have done so.
    The plaintiffs would merely need to establish “more than a
    bare suspicion” of impropriety—in other words, “evidence
    that would warrant a belief by a reasonable person that the
    alleged Government impropriety might have occurred.”
    CAMERANESI V. U.S. DEP’T OF DEFENSE                        43
    
    Favish, 541 U.S. at 174
    . The plaintiffs have easily satisfied
    that standard by pointing to the troubled history of SOA,
    which led Congress to acknowledge a need for new vetting
    and oversight procedures. The majority simply ignores the
    relevance of this pre-2001 history. Yet it is precisely because
    of the problems that plagued the Institute’s predecessor that
    the public has such a strong interest in determining whether
    or not the reforms implemented to correct those problems
    have been effective.2
    III
    What I have shown thus far, I hope, is that the public
    interest in disclosure is much stronger than the majority is
    willing to allow. But what about the privacy interests at
    2
    The majority makes one additional mistake in evaluating the
    strength of the public interest in disclosure. The majority assumes that
    FOIA does not protect the public’s interest in learning whether the
    students who attend the Institute commit human rights abuses after
    graduating because the public’s interest is limited to “monitoring the
    DOD’s performance of its current statutory duties with respect to
    WHINSEC.” Maj. op. at 4 n.1, 31. That assumption is wrong. The
    public interest in disclosure protected by FOIA encompasses (but is not
    limited to) “information that sheds light on an agency’s performance of its
    statutory duties.” Reporters 
    Committee, 489 U.S. at 773
    . FOIA also
    protects, more broadly, “the citizens’ right to be informed about ‘what
    their government is up to,’” which reflects FOIA’s core purpose of
    “open[ing] agency action to the light of public scrutiny.” 
    Id. at 773,
    774
    (quoting 
    Rose, 425 U.S. at 372
    ). Here, that broader interest encompasses
    information necessary to assess whether the Institute continues to train
    students who later commit human rights abuses upon returning to their
    home countries after graduation. Contrary to the majority’s view, the
    post-graduation conduct of the Institute’s attendees does shed light on the
    Army’s own conduct in running the Institute—which is why the
    revelations about SOA’s graduates in the 1990s nearly led to the school’s
    closure.
    44        CAMERANESI V. U.S. DEP’T OF DEFENSE
    stake? Are they strong enough to outweigh the public interest
    in disclosure? That depends on how grave we believe the risk
    of harm to the foreign students and instructors might be if
    their names are disclosed. Ordinarily, I would be inclined to
    give considerable deference to the judgment of military
    officials about the gravity of the risks posed by disclosure of
    potentially sensitive information. The reason I think we
    should be more skeptical here is that the military itself
    determined for a decade, from 1994 to 2004, that the risks of
    disclosure were not sufficiently compelling to justify
    withholding the names under Exemption 6. During this
    period, the Army disclosed not only the names of all foreign
    students and instructors who attended the Institute each year,
    but also the names of all foreign students and instructors who
    had attended the Institute and its predecessor dating back to
    1946—some 60,000 names in all.
    It would be one thing if the Department of Defense had
    informed us that its risk assessment changed in 2005 because
    a foreign student or instructor had been targeted for
    harassment or violence due to his affiliation with the Institute.
    That would make it easy to understand the Department’s
    about-face. But here, the Defense Department pointed to no
    such event, and indeed, so far as the record discloses, none of
    the 60,000 individuals whose names have been publicly
    released has ever been the target of harassment or violence
    based on their having attended the Institute or its predecessor.
    The Department of Defense is certainly correct in arguing
    that it is not required to show some past incident of harm in
    order to invoke Exemption 6 as a basis for non-disclosure.
    But in light of the history involved here, I think we are
    entitled to demand from the Department some explanation for
    why it is now saying that the risks of disclosure are too great
    CAMERANESI V. U.S. DEP’T OF DEFENSE                         45
    when apparently it did not believe that to be true before.
    Otherwise, we are simply rubber-stamping the government’s
    decision.
    The declarations submitted by the Department of Defense
    do not provide a satisfactory explanation (or frankly any
    explanation at all). The Department provided just two short
    declarations from a public affairs staffer at the Institute
    named Lee Rials. Attached to one of his declarations is a
    transcript of testimony given by two generals at a 2010
    congressional hearing devoted to other subjects during which
    the generals answered a single question about the Institute.
    (This is the congressional testimony to which the majority
    refers. See Maj. op. at 14–15.) The Rials declarations assert,
    based on “Defense Intelligence Agency assessments” which
    the government chose not to submit, that disclosure of the
    foreign students’ and instructors’ names would increase the
    risk of retaliation from three sources: (1) “the intelligence and
    security apparatuses of countries hostile to U.S. interests”;
    (2) “terrorist organizations operating in the Western
    Hemisphere”; and (3) “drug trafficking organizations
    operating in the Western Hemisphere.” But the risks of
    retaliation from these sources were undoubtedly present
    during the 1994–2004 time period as well. They did not just
    pop up beginning in 2005. Rials’ declarations offer no
    explanation for why the military has determined that those
    risks had increased sufficiently by 2005 to warrant striking a
    different balance between privacy interests and the public
    interest in disclosure.3
    3
    The majority’s only response to this point is to speculate that “it is
    equally likely that escalating violence influenced the government’s
    decision to change its nondisclosure policy in 2005.” Maj. op. at 33 n.19.
    The problem with this response is just that—it is predicated entirely on
    46          CAMERANESI V. U.S. DEP’T OF DEFENSE
    At oral argument, the government’s lawyer asserted that
    the terrorist attacks of September 11, 2001, caused the
    Department of Defense to reassess its prior policy of
    disclosing the names. The main problem with that
    explanation: It appears nowhere in the declarations the
    government submitted. Neither the Rials declarations nor the
    testimony from the two generals mentions the September 11
    attacks. The government did submit a copy of a November
    2001 Defense Department memo that announced, in light of
    the recent attacks, a new policy with respect to “DoD
    personnel” of withholding “lists of names and other
    personally identifying information.” However, Rials did not
    cite this memo in explaining the Department of Defense’s
    2005 decision to stop disclosing the names of the Institute’s
    foreign students and instructors, and the government failed to
    offer any other declaration—let alone one from a military
    officer—explaining the memo’s role in the 2005 decision-
    making process.
    The link between the November 2001 memo regarding
    “DoD personnel” and the Army’s 2005 decision to stop
    disclosing the names of foreign military personnel attending
    the Institute is not so obvious that we can assume a
    connection without any supporting evidence. For one thing,
    it is not by any means clear that the memo was intended to
    apply to foreign students and instructors at a U.S. military
    training school; the memo’s focus appears to be on protecting
    speculation. The majority cannot identify any evidence in the record of
    escalating violence that would justify the Defense Department’s
    withholding decision in 2005 because the Department submitted no such
    evidence. And because the government bears the burden of establishing
    a basis for withholding under Exemption 6, that dearth of evidence is fatal
    to its claim. See 
    Ray, 502 U.S. at 173
    .
    CAMERANESI V. U.S. DEP’T OF DEFENSE                47
    the identities of U.S. military personnel, who would be
    obvious targets for attack in the wake of September 11. Had
    the memo also been intended to cover foreign students and
    instructors at the Institute, it is inconceivable that the Army
    would have continued to disclose their names in response to
    FOIA requests for more than three years after the memo’s
    issuance, which is what happened here. For another thing,
    the November 2001 memo relied on an Exemption 6
    balancing analysis (under which privacy interests were
    deemed to prevail), but that analysis is quite different for the
    two groups of personnel. The public interest in knowing
    which foreign students our government chooses to train
    militarily and what comes of that training is much stronger
    than any public interest that might exist in the disclosure of
    the identities of U.S. military personnel.
    *         *        *
    Under FOIA, Congress has established a “strong
    presumption in favor of disclosure,” and it has placed “the
    burden on the agency to justify the withholding of any
    requested documents.” 
    Ray, 502 U.S. at 173
    . Had the
    government provided a sturdier evidentiary foundation for its
    decision to withhold the requested information, I would have
    readily agreed with my colleagues’ resolution of this appeal.
    On this record, though, I think we are compelled to reject the
    government’s invocation of Exemption 6. I would therefore
    affirm the district court’s decision.
