    MEMORANDUM OPINION
    The plaintiff, Gary Sebastian Brown, III, proceeding pro se and in forma pauperis, brings
    this lawsuit against the defendant, the Federal Bureau of Investigation (“FBI”), pursuant to the
    Freedom of Information Act (“FOIA”), 
    5 U.S.C. § 552
    . See Complaint, ECF No. 1, at 1. Currently
    pending before the Court is the FBI’s Motion for Summary Judgment (“MSJ”), ECF No. 23, along
    with its accompanying statement of material facts (“SOF”), ECF No. 23-1; the FBI’s
    Memorandum of Points and Authorities in Support of Defendant’s Motion for Summary Judgment
    (“MSJ Mem.”), ECF No. 23-2; the Declaration of Michael G. Seidel––the FBI’s Section Chief
    of the Record/Information Dissemination Section (“RIDS”), Information Management
    Division (“IMD”)(“Seidel Decl.”), ECF No. 23-3; and the FBI’s supporting Exhibits (“MSJ
    Exs.”), ECF No. 23-4. In response, the plaintiff filed his Memorandum of Points and Authorities
    in Support of Plaintiff’s Opposition to Defendant’s Motion for Summary Judgment (“Pl.’s
    Opp’n”), ECF No. 25, along with his supporting Exhibits to Plaintiff’s Opposition to Defendant’s
    Motion for Summary Judgment (“Opp’n Exs.”), ECF No. 25-1, to which the FBI filed its Reply
    (“Def.’s Reply”), ECF No. 27. On May 26, 2023, the plaintiff filed a Motion for Leave to
    Amend/Supplement his Opposition, ECF No. 28, and with it, filed what the Court construes as a
    1
    Surreply (“Surreply”), ECF No. 29. Even though neither this Court’s Local Rules nor the Federal
    Rules of Civil Procedure provide the right to file a surreply, given the plaintiff’s pro se status, the
    Court will grant his request that his Surreply be considered in resolving the defendant’s request
    for summary judgment. After review of the entire record, and for the reasons stated herein, the
    FBI’s Motion for Summary Judgment will be granted in full, and this matter will be closed.
    BACKGROUND
    On November 7, 2019, Brown submitted a FOIA Request to the FBI requesting:
    any witness accounts, narratives, or statements provided by witnesses
    from an incident which occurred on December 2nd, 2015 at the Inland
    Regional Center in San Bernardino, CA. This was a high profile massacre
    involving some 14 dead and 22 injured, allegedly committed by Tashfeen
    Malik and Syed Farook. Specifically, I am seeking accounts, narratives,
    and statements from witnesses who were located in the conference room
    where the attack mainly took place. Of particular importance to this
    requester are any descriptions of the perpetrators such as, the number of
    attackers, their behavior, apparel, equipment, and any other details
    regarding their appearance.
    MSJ Ex. A (FOIA Request); see Seidel Decl. ¶ 6. Upon receipt of this request, the FBI conducted
    a search to determine if there were any previously processed records responsive to the Request,
    and successfully located records about the December 2, 2015 terrorist attack and mass shooting at
    the Inland Regional Center in San Bernardino, California. See Seidel Decl. ¶ 7. The FBI
    responded to the plaintiff by letter on November 25, 2019, assigning the plaintiff’s FOIA Request
    “No. 1452736-000,” and enclosing 19 pages of records that were previously released. Id.; see MSJ
    Ex. B (Letter Dated 11/25/19). The FBI further indicated that the plaintiff could request an
    additional search for records if he was unsatisfied with what he had been provided. 
    Id.
    On December 12, 2019, the plaintiff requested that the FBI continue its search and provide
    him with additional records. Seidel Decl. ¶ 8; see MSJ Ex. C (Letter Dated 12/12/19). On January
    2
    3, 2020, the FBI sent a letter to the plaintiff, acknowledging the plaintiff’s request, and reassigning
    his FOIA Request “No. 1452736-001.” Seidel Decl. ¶ 9; see MSJ Ex. D (Letter Dated 1/2/20).
    On February 26, 2020, the FBI advised the plaintiff that the material he requested was
    found in an investigative file that was exempt from disclosure pursuant to 
    5 U.S.C. § 552
    (b)(7)(A)
    due to an associated pending or prospective law enforcement proceeding, and that release of the
    information could interfere with that proceeding. Seidel Decl. ¶ 10; see MSJ Ex. E (Letter Dated
    2/26/20). The FBI also indicated that it was administratively closing FOIA Request No. 1452736-
    001 and advised the plaintiff of his right to appeal that decision. See MSJ Ex. E. Presumably, the
    plaintiff did not receive this letter because, on July 15, 2020, he contacted the FBI, indicating that
    he that was still awaiting a response to FOIA Request No. 1452736-001. See Seidel Decl. ¶ 11;
    see MSJ Ex. F (Letter Dated 7/15/20). In response, the FBI then reopened the matter on July 29,
    2020, reassigned it “No. 1452736-002,” and re-sent the plaintiff the letter dated February 26, 2020.
    Seidel Decl. ¶ 12; see MSJ Ex. G (Letter Dated 7/29/20).
    On September 17, 2020, the plaintiff appealed the FBI’s withholdings pursuant to §
    552(b)(7)(A), see Seidel Decl. ¶ 13; MSJ Ex. H (Appeal Letter), and on December 1, 2020, the
    Department of Justice’s Office of Information Policy (“OIP”) affirmed the FBI’s determination,
    see Seidel Decl. ¶ 13; MSJ Ex. I (OIP Acknowledgment Letter); MSJ Ex. J (OIP Decision as to
    Appeal No. A-2021-02231).
    In May 2022, the FBI’s Los Angeles Field Office determined the associated investigation
    was no longer pending, rendering the FBI’s previous categorical reliance on § 552(b)(7)(A)
    inapplicable. Seidel Decl. ¶ 15. On July 29, 2022, the FBI made its second and final release of
    records to the plaintiff, advising that it had reviewed 411 pages, releasing 406 pages part,
    withholding five pages in full, and relying on 
    5 U.S.C. §§ 552
    (b)(l), (b)(3), (b)(6), (b)(7)(A),
    3
    (b)(7)(C), (b)(7)(D), and (b)(7)(E) for the information withheld. See 
    id. ¶¶ 16
    , 90–92; MSJ Ex. K
    (Release Letter Dated 7/29/22); see also Opp’n Ex. B, ECF No. 25-1 (the FBI’s FOIA Release).
    LEGAL STANDARD OF REVIEW
    FOIA “sets forth a policy of broad disclosure of Government documents in order ‘to ensure
    an informed citizenry, vital to the functioning of a democratic society.’” FBI v. Abramson, 
    456 U.S. 615
    , 621 (1982) (quoting NLRB v. Robbins Tire & Rubber Co., 
    437 U.S. 214
    , 242 (1978)).
    “[D]isclosure, not secrecy, is the dominant objective of the Act.” Dep't of Air Force v. Rose, 
    425 U.S. 352
    , 361 (1976). FOIA accordingly “mandates release of properly requested federal agency
    records, unless the materials fall squarely within one of nine statutory exemptions.” Hunton &
    Williams LLP v. EPA, 
    346 F. Supp. 3d 61
    , 72 (D.D.C. 2018) (citing Milner v. Dep't of Navy, 
    562 U.S. 562
    , 565 (2011); Students Against Genocide v. Dep’t of State, 
    257 F.3d 828
    , 833 (D.C. Cir.
    2001); 
    5 U.S.C. § 552
    (a)(3)(A), (b)). And “even if some materials from the requested record are
    exempt from disclosure, any reasonably segregable information from those documents must be
    disclosed after redaction of the exempt information,” unless the non-exempt portions are
    “inextricably intertwined with exempt portions.” 
    Id.
     (internal quotation marks omitted) (quoting
    Johnson v. EOUSA, 
    310 F.3d 771
    , 776 (D.C. Cir. 2002)).
    “FOIA cases typically and appropriately are decided on motions for summary judgment.”
    Defs. of Wildlife v. Border Patrol, 
    623 F. Supp. 2d 83
    , 87 (D.D.C. 2009) (citing Bigwood v. Agency
    for Int'l Dev., 
    484 F. Supp. 2d 68
    , 73 (D.D.C. 2007)). An agency is entitled to summary judgment
    if no material facts are genuinely in dispute and the agency demonstrates “that its search for
    responsive records was adequate, that any exemptions claimed actually apply, and that any
    reasonably segregable non-exempt parts of records have been disclosed after redaction of exempt
    information.” Competitive Enter. Inst. v. EPA, 
    232 F. Supp. 3d 172
    , 181 (D.D.C. 2017). To carry
    4
    its burden, the agency must provide “a relatively detailed justification, specifically identifying the
    reasons why a particular exemption is relevant and correlating those claims with the particular part
    of the withheld document to which they apply.” Elec. Priv. Info. Ctr. v. DEA, 
    192 F. Supp. 3d 92
    ,
    103 (D.D.C. 2016) (quoting Mead Data Cent., Inc. v. Dep't of Air Force, 
    566 F.2d 242
    , 251 (D.C.
    Cir. 1977)).
    DISCUSSION
    I.      Adequacy of the Search
    The adequacy of an agency's search is measured by a standard of reasonableness under the
    attendant circumstances. Truitt v. Dep't of State, 
    897 F. 2d 540
    , 542 (D.C. Cir. 1990). To satisfy
    its burden, an agency must show that it “has conducted a search reasonably calculated to uncover
    all relevant documents.” Elliott v. Dep't of Agric., 
    596 F. 3d 842
    , 851 (D.C. Cir. 2010) (quotation
    omitted), cert. denied, 
    560 U.S. 973
     (2010). It may base its showing on declarations submitted in
    good faith, see Truitt, 
    897 F.2d at 542
    , provided that they explain, in reasonable detail, the scope
    and method of the search, see Morley v. CIA, 
    508 F.3d 1108
    , 1116 (D.C. Cir. 2007) (internal
    citations omitted).
    Once the agency has provided a “reasonably detailed” declaration, the burden shifts to the
    FOIA requester to produce “countervailing evidence” suggesting that a genuine dispute of material
    fact exists as to the adequacy of the search. 
    Id.
     (internal citation and quotation marks omitted).
    “In the absence of contrary evidence, such affidavits or declarations are sufficient to demonstrate
    an agency's compliance[.]” North v. DOJ, 
    774 F. Supp. 2d 217
    , 222 (D.D.C. 2011) (citing Perry
    v. Block, 
    684 F.2d 121
    , 127 (D.C. Cir. 1982)). Here, the Court finds that the FBI has submitted a
    reasonably detailed declaration establishing that it conducted an adequate search.
    5
    The FBI’s declarant, Seidel, has considerable tenure and a wealth of experience in
    evaluating FOIA requests, see Seidel Decl. ¶¶ 1–3, and attests, in his official capacity, that he (1)
    is well-versed in the procedures employed by the agency, and (2) has personal knowledge of FOIA
    Request Nos. 1452736-000, 1452736-001, and 1452736-002, id. ¶ 3.                In addition to being
    reasonably detailed, the Declaration appears to have been made in good faith.
    Seidel identifies and details the record systems and locations searched by the FBI,
    including why the relevant information would be in those locations and systems, the search terms
    used to conduct the search, and the scope of the search. See id. ¶¶ 17–27. More specifically, he
    details the FBI’s Central Records System (“CRS”) and the other internal electronic, integrated case
    management systems and their indices, most specifically, “Sentinel” (and the now-integrated
    Automated Case Support––“ACS”) and explains why the FBI searched those databases. See id.
    He further states that RIDS conducted a search of the CRS for potentially responsive records, by
    employing its automated indices, available through Sentinel via its search function, by using the
    search term “Inland Regional Center,” and it successfully located responsive records for “witness
    interviews,” tailored to the scope of the plaintiff’s FOIA Request. See id. ¶¶ 24–27; see also MSJ
    Ex. A.
    Put simply, the FBI searched sites where the information was reasonably likely to be found.
    See Seidel Decl. ¶¶ 24–27. Seidel states that
    CRS is indexed in a manner that meets the FBI's investigative needs and
    priorities and allows FBI personnel to locate pertinent files. The general
    indices comprise multiple indices (including Sentinel . . . ) on a variety of
    subjects to include individuals, organizations, events, and other subjects
    of investigative interest that are indexed for future retrieval.
    Id. ¶ 20. Furthermore, he represents that
    FBI personnel rely on Sentinel to locate records and documents to fulfill
    essential functions, such as conducting criminal, counterterrorism, and
    6
    national security investigations; background investigations; citizenship
    and employment queries; and security screening, to include presidential
    protection. Sentinel’s index search methodology allows FBI personnel to
    query the CRS for indexed subjects in case files.
    Id. ¶ 22. Seidel explains that these “indices are comparable to a digital version of a library's card
    catalog[,]” and are neatly organized by “main entries” (for subjects of an investigation) and
    “reference entries” (for non-subjects associated with as investigation), all of which contain
    information regarding associated individuals, organizations, and events. See id. ¶¶ 20–21. Indeed,
    RIDS searched CRS and Sentinel because those indices “provide access to a comprehensive,
    agency-wide set of indexed data on a wide variety of investigative and administrative subjects and
    consist of millions of searchable records that are updated daily with newly indexed information.”
    Id. ¶ 24.
    Seidel expressly attests that the search was adequate and reasonably likely to locate
    responsive records, see id. ¶¶ 17, 25–26, 28, and based on the information provided, the Court
    agrees. See Mobley v. CIA, 
    806 F.3d 568
    , 581 (D.C. Cir. 2015) (finding the FBI’s search of the
    CRS to be adequate because of, in part, an agency declaration asserting that the FBI’s search was
    “reasonably likely to produce the information [the plaintiff] requested”) (citation omitted).
    In response, the plaintiff argues that the FBI’s search was “not diligent and reasonable as
    the scope of [his] request was construed as a request for interviews only.” Pl.’s Opp’n at 3. He
    concedes, however, that his request for witness “accounts, narratives, and statements,” MSJ Ex.
    A, would likely be included in the FBI’s search for “interviews,” but then speculates that additional
    materials in those three sub-categories could exist outside of the “interview” umbrella, see Pl.’s
    Opp’n at 3; see also Surreply at 3–9. For example, he contends that potential audio recordings and
    transcripts of 911 calls––which he has heard on television news––do not constitute “interviews,”
    but may be available to the FBI in a more expanded search. See Pl.’s Opp’n at 3; Surreply at 3–4,
    7
    7. He also conjectures that potential “logs or audio records of police radio communications[,]”
    and “raw recordings of witness interviews[,]” may exist outside of the FBI’s existing search
    parameters. See Pl.’s Opp’n at 3–4.
    An agency has a duty to construe a FOIA request liberally. Nation Magazine, Washington
    Bureau v. U.S. Customs Serv., 
    71 F.3d 885
    , 890 (D.C. Cir. 1995). But “even a ‘liberal’ reading”
    of the plaintiff’s FOIA Request does not support his assertion that the FBI was somehow obligated
    to retrieve local law enforcement logs, or outside media and audio recordings, based on the scope
    of his request. See Looks Filmproduktionen GmbH v. CIA, 
    199 F. Supp. 3d 153
    , 169–70 (D.D.C.
    2016) (internal quotation marks and citations omitted) (finding both the CIA’s interpretation of a
    FOIA request and its search to be reasonable after the plaintiff argued that his request was misread,
    and contended the agency’s interpretation was “overly narrow,” because an agency is not obligated
    to search for tangential material); see also Leopold v. Dep’t of Justice, 
    301 F. Supp. 3d 13
    , 25 n.6
    (D.D.C. 2018) (explaining the difference between an agency improperly delimiting a search,
    versus properly and necessarily narrowing the scope of a search to facilitate retrieving the records
    actually requested); Dillon v. Dep’t of Justice, 
    102 F. Supp. 3d 272
    , 286–87 (D.D.C. 2015) (finding
    that “an agency’s decision to conduct a ‘targeted search’ based on the scope of the plaintiff's
    request is proper under the FOIA”) (quoting Bloomgarden v. Dep't of Justice, 
    10 F. Supp. 3d 146
    ,
    153 (D.D.C. 2014) (agreeing with agency's assertion that its “targeted search for personnel
    documents . . . was reasonable in light of the narrow nature of [the] plaintiff's request[.]”)).
    Additionally, the FBI “need not extend the meaning of the request to include things not
    asked for.” Wallick v. Agrig. Marketing Srvc., 
    281 F. Supp. 3d 56
    , 68 (D.D.C. 2017) (concluding
    that the defendant properly interpreted the request and conducted an adequate search where the
    plaintiff unreasonably expected the agency to interpret his request in a nuanced manner beyond its
    8
    plain meaning) (collecting cases). And the plaintiff’s own preferences and suppositions cannot
    dictate the reasonableness of the scope of the FBI’s search. 
    Id.
     (“[U]nder [the plaintiff's] approach,
    which would allow a requester to dictate, through search instructions, the scope of an agency's
    search, the reasonableness test for search adequacy long adhered to in this circuit would be
    undermined.”). This is particularly important where, as here, a plaintiff has presented only mere
    speculation that additional materials might be found in the possession of an agency, see Meeropol
    v. Meese, 
    790 F.2d 942
    , 954 (D.C. Cir. 1986), and a requester is only entitled to records actually
    retained by the agency, see Bonfilio v. Occupational Safety & Health Administration, 
    320 F. Supp. 3d 152
    , 157 (D.D.C. 2018) (citing Wilbur v. CIA, 
    355 F.3d 675
    , 678 (D.C. Cir. 2004); Yeager v.
    DEA, 
    678 F.2d 315
    , 321 (D.C. Cir. 1982)). And to the extent that the plaintiff, after reviewing
    the FBI’s release of records, now seeks to expand the scope of his FOIA Request by and through
    this litigation, he may not do so. See, e.g., Houser v. Church, 
    271 F. Supp. 3d 197
    , 204 (D.D.C.
    2017) (finding that a requester may not “expand the scope of his FOIA request in the course of
    litigation”) (citing Donoghue v. Office of Info. Policy, Dep't of Justice, 
    157 F. Supp. 3d 21
    , 23 n.2
    (D.D.C. 2016); Coss v. Dep't of Justice, 
    98 F. Supp. 3d 28
    , 34 (D.D.C. 2015)).
    Even assuming arguendo that the FBI is in possession of call-center transcripts, logs or
    audio of police radio communications, or other “raw recordings,” see Pl.’s Opp’n at 3–4; Surreply
    at 3–4, 7, the plaintiff’s FOIA Request, as drafted, does not mandate or ensure their retrieval. “A
    search need not be perfect, only adequate, and adequacy is measured by the reasonableness of the
    effort in light of the specific request[,]” Meeropol, 
    790 F.2d at 956
    , and in any event, a search “is
    not unreasonable simply because it fails to produce all relevant material[,]” 
    id.
     at 952–53; see
    Mobley, 
    806 F.3d at 583
     (collecting cases).
    9
    “In determining the proper scope of a FOIA request, ‘[t]he linchpin inquiry is whether the
    agency is able to determine ‘precisely what records (are) being requested.’” McKinley v. FDIC,
    
    807 F. Supp. 2d 1
    , 5 (D.D.C.2011) (alterations in original) (quoting Yeager, 
    678 F.2d at 326
    ); see
    also American Chemistry Council, Inc. v. Health & Human Servs., 
    922 F. Supp. 2d 56
    , 62 (D.D.C.
    2013) (“Agencies . . . need not expand their searches beyond ‘the four corners of the request,’ nor
    are they ‘required to divine a requester's intent.’”) (quoting Landmark Legal Found. v. EPA, 
    272 F. Supp. 2d 59
    , 64 (D.D.C. 2003)). Here, the FBI analyzed the plaintiff’s FOIA Request and
    determined that a search of the CRS automated index, via Sentinel, would locate responsive
    material. See Def.’s Reply at 2–3 (quoting Seidel Decl. ¶ 24). It searched “millions of searchable
    records that are updated daily with newly indexed information[,]” and specifically searched for
    records involving the San Bernadino shooting. See id. at 3 (quoting Seidel Decl. ¶¶ 17, 24–25).
    In doing so, it retrieved over 400 pages of records, see Seidel Decl. ¶¶ 16, 90–92, comprised of
    “FD-302s”––internal FBI forms that memorialize a myriad of evidence and information from
    witness interviews, compiled in furtherance of the FBI’s investigation and for potential use in
    future court proceedings, see MSJ Ex. L (Vaughn Index) (“VI”) at A2, and it then released, in part,
    nearly all of them, see Opp’n Ex. B.
    The Court finds it reasonable that the FBI construed the plaintiff’s request for witness
    “accounts, narratives, and statements” as witness “interviews,” and that the FD-302s would be the
    source where responsive records would be found, given the purpose of the FD-302 and the
    comprehensive nature of the information contained therein. See id. All circumstances considered,
    (1) the FBI properly interpreted the scope of the plaintiff’s FOIA Request, and (2) its search
    parameters and methods were appropriate. See, e.g., Cole v. Copan, No. 19-cv-1182, 
    2020 WL 7042814
    , at *4 (D.D.C. Nov. 30, 2020) (entering summary judgment for the defendant and finding
    10
    that the plaintiff’s challenge to the scope of the agency’s search, based on a semantics debate over,
    inter alia, the interpretation of the phrase “input data,” was an improper attempt to reframe his
    request) (citing Larson v. Dep't of State, 
    565 F.3d 857
    , 869 (D.C. Cir. 2009) (upholding a district
    court's narrow interpretation of a FOIA request where the request did not “reasonably suggest” the
    broad scope argued by the plaintiff)). In sum, the Court finds that the FBI has met its burden in
    showing that it conducted an adequate search.
    II.       Adequacy of the Vaughn Index
    In FOIA cases, a motion for summary judgment is typically supported by a “Vaughn
    index,” as derived from Vaughn v. Rosen, 
    484 F.2d 820
     (D.C. Cir. 1973), cert. denied, 
    415 U.S. 977
     (1974). No set formula exists for an adequate Vaughn index, because “the critical elements
    of the Vaughn index lie in its function, and not its form.” Kay v. FCC, 
    976 F. Supp. 23
    , 35 (D.D.C.
    1997), aff’d, 
    172 F.3d 919
     (D.C. Cir. 1998). The purpose of a Vaughn index is “to permit adequate
    adversary testing of the agency's claimed right to an exemption,” and thus must contain “an
    adequate description of the records” and “a plain statement of the exemptions relied upon to
    withhold each record.” Nat'l Treas. Emps. Union v. Customs Serv., 
    802 F.2d 525
    , 527 n.9 (D.C.
    Cir. 1986).
    Although a Vaughn index can be an important component of FOIA briefing,
    the Court may award summary judgment solely on the basis of information
    provided by the department or agency in declarations when the
    declarations describe ‘the documents and the justifications for
    nondisclosure with reasonably specific detail, demonstrate that the
    information withheld logically falls within the claimed exemption, and are
    not controverted by either contrary evidence in the record nor by evidence
    of agency bad faith.’

    656 F.2d 724

    147 F.3d 992
    , 998 n.4 (D.C. Cir. 1998) (“The form of the Vaughn index is unimportant and
    affidavits providing similar information can suffice.”) (citing Gallant v. NLRB, 
    26 F.3d 168
    , 172–
    73 (D.C. Cir. 1994)).
    As noted above, the located documents consisted of FD-302s, which are adequately
    described by the FBI. See VI at A2. The FBI’s Vaughn Index, see VI at A1–A2, 1–10, and the
    comprehensive Declaration submitted by Seidel, see Seidel Decl. ¶¶ 28–92, considered together,
    sufficiently describe the records (or portions of records) withheld and their associated Bates
    numbers, as well as the exemptions justifying the associated information withheld. See id.; VI at
    A1–A2, 1–10. For these reasons, the Court finds that the Vaughn Index, along with the Seidel
    Declaration, are sufficiently specific “to permit adequate adversary testing of the agency's claimed
    right” to the FBI’s reliance on the invoked exemptions. Nat'l Treas. Emps. Union, 
    802 F.2d at 527
    .
    III.     FOIA Exemptions & Segregability
    The FBI relied on several different FOIA exemptions in withholding information requested
    by the plaintiff. See Seidel Decl. ¶¶ 12–13; see generally Opp’n Ex. B. Notably, “even if [the]
    agency establishes an exemption, it must nonetheless disclose all reasonably segregable,
    nonexempt portions of the requested record(s).” Roth v. Dep’t of Justice, 
    642 F.3d 1161
    , 1167
    (D.C. Cir. 2011) (internal quotation marks and citation omitted). “[I]t has long been the rule in
    this Circuit that non-exempt portions of a document must be disclosed unless they are inextricably
    intertwined with exempt portions.” Wilderness Soc'y v. Dep't of Interior, 
    344 F. Supp. 2d 1
    , 18
    (D.D.C. 2004) (quoting Mead Data Cent., 566 F.2d at 260). Thus, an agency must provide “a
    detailed justification and not just conclusory statements to demonstrate that all reasonably
    segregable information has been released.” Valfells v. CIA, 
    717 F. Supp. 2d 110
    , 120 (D.D.C.
    12
    2010) (internal quotation marks and citation omitted), aff’d sub nom., 
    666 F.3d 1330
     (D.C. Cir.
    2010). However, “[a]gencies are entitled to a presumption that they complied with the obligation
    to disclose reasonably segregable material,” which must be overcome by some “quantum of
    evidence” from the requester. Sussman v. U.S. Marshals Serv., 
    494 F.3d 1106
    , 1117 (D.C. Cir.
    2007), aff’d sub nom., 
    666 F.3d 1330
     (D.C. Cir. 2011).
    A declaration and/or Vaughn index attesting to the performance of a review of the
    documents, and describing the withholdings, satisfies the FOIA's segregability requirement. See,
    e.g., Johnson, 310 F.3d at 776; Loving v. Dep’t of Justice, 
    550 F.3d 32
    , 41 (D.C. Cir. 2008), cert.
    denied, 
    558 U.S. 945
     (2009). Here, the FBI attests that Seidel and others extensively reviewed the
    responsive material and that all non-exempt and segregable information was produced. See Seidel
    Decl. ¶¶ 90–93.
    The plaintiff’s challenge to the FBI’s use of its exemptions is difficult to comprehend and
    somewhat amalgamated. At the outset, he states that he “does not take issue with the language of
    Defendant’s [redaction and withholding] justifications [under the asserted exemptions] and
    concedes that any such content rightly identified under said justification are properly withheld,”
    and he indicates that he only objects to the FBI’s segregability analysis. See Pl.’s Opp’n at 5.
    However, his segregability challenge reveals that he, at least in part, challenges the use of certain
    exemptions. See 
    id.
     at 5–42; Surreply at 8–19. More specifically, he asserts that the descriptions
    of the shooters are segregable and should be released, and in doing so, challenges the FBI’s
    redaction of that information pursuant to Exemptions 6 and 7(C), and Exemption 7(D), on the
    documents designated as Bates Nos. 1–4, 6–7, 16–17, 24–27, 30–31, 33, 35–36, 38–39, 43–44, 47,
    50–51, 54, 58, 61–62, 74–76, 78–79, 81–82, 85–86, 87–88, 93–94, 96–99, 101–102, 106–07, 101–
    102, 106–07, 109, 111–12, 114, 116–17, 120–21, 124, 126–27, 130, 133–34, 137–38, 139–40,
    13
    143, 146–47, 153–54, 156–57, 159, 160–61, 163, 165–70, 174–75, 177–78, 180–81, 185–89, 196–
    99, 201–02, 206, 208–09, 211–12, 213, 219–20, 223–24, 227–28, 234–37, 241–43, 248–49, 253–
    54, 259–61, 267–68, 272–73, 277, 278–79, 280, 283–84, 286–87, 290, 293–98, 300–10, 313–46,
    349–63, 365–66, 369–70, 373–74, 380–81, 384, 1 387–88, 391–93, 396–97, 403, and 407–10. See
    
    id.
     The Court will thus discuss the propriety of each of the FBI’s noted exemptions, and where
    relevant, the segregability of the information withheld thereunder.
    A. 
    5 U.S.C. § 552
    (b)(1) (“Exemption 1”)
    The FBI relies on FOIA Exemption 1 as the basis for withholding certain information, see
    Seidel Decl. ¶ 34–35, and the plaintiff presents no opposition to its use of this Exemption. FOIA
    Exemption 1 provides that matters “specifically authorized under criteria established by an
    Executive [O]rder to be kept secret in the interest of national defense or foreign policy and . . . are
    in fact properly classified pursuant to such Executive [O]rder” are exempt from production under
    the FOIA. 
    5 U.S.C. § 552
    (b)(1). “The [agency's] arguments need only be both ‘plausible’ and
    ‘logical’ to justify the invocation of a FOIA exemption in the national security context.” ACLU v.
    Dep't of Defense, 
    628 F.3d 612
    , 624 (D.C. Cir. 2011) (quoting Wolf v. CIA, 
    473 F.3d 370
    , 374–75
    (D.C. Cir. 2007)); see also Morley, 
    508 F.3d at 1124
     (“[T]he text of Exemption 1 itself suggests
    that little proof or explanation is required beyond a plausible assertion that information is properly
    classified.”).
    The FBI withheld information pursuant to Exemption 1 under Executive Order 13526 (“EO
    13526”), see Seidel Decl. ¶ 34–35; VI at 1, 2, 9 (withholding in part Bates Nos. 42, 46, 49, 53, 57,
    60, 64, 66, 364, 368, 372, 376, 379, 383, 386, 390, and 395), which establishes procedural and
    1
    Exemption 6 and 7(C) are both used as the basis for redacting information on this page, but
    not Exemption 7(D). See VI at 9.

    substantive requirements for classification of eight categories of national security information, see
    
    75 Fed. Reg. 707
     (Dec. 29, 2009).
    [I]f information that is responsive to a FOIA request fits into any of the
    eight categories, and if an original classifying authority has designated the
    information classified based on that authority's determination that the
    unauthorized disclosure of the information reasonably could be expected
    to result in damage to the national security, the information has properly
    been deemed ‘classified’ and the government can invoke Exemption 1 to
    withhold the information from disclosure under the FOIA.
    Elec. Privacy Info. Ctr. v. Dep’t of Justice, 
    296 F. Supp. 3d 109
    , 124–25 (D.D.C. 2017). Here, the
    FBI specifically relies on § 1.4(c), see Seidel Decl. ¶¶ 37–45, which protects the category of
    information pertaining to “intelligence activities (including covert action), intelligence sources or
    methods, or cryptology” if that information “could reasonably be expected” to damage national
    security, see EO 13526 75 § 1.4(c).
    Seidel attests that he “personally and independently examined the information withheld
    pursuant to FOIA Exemption (b)(1) . . . [and] determined that the classified information continues
    to warrant classification at the ‘Secret’ level . . . pursuant to E.O. 13526 § l .4(c)[.]” Seidel Decl.
    ¶ 36. This he asserts is “because its release would reveal actual intelligence activities and methods
    used by the FBI against specific targets of foreign counterintelligence investigations or operations;
    identify a target of a foreign counterintelligence investigation; and/or disclose the intelligence
    gathering capabilities of the activities or methods directed at specific targets.” Id. ¶ 38. Seidel
    further maintains that disclosure of this “specific information regarding the intelligence
    activities[,]” for which this Exemption was asserted, “could reasonably be expected to cause
    serious damage to the national security,” because: “(1) disclosure would reveal current targets of
    specific FBI national security investigations; and (2) disclosure would reveal the criteria used and
    priorities assigned to current intelligence or counterintelligence investigations.” Id. ¶ 39. Indeed,
    15
    the FBI asserts that “hostile entities could develop countermeasures which would . . . severely
    disrupt the FBI's intelligence gathering capabilities . . . [and] efforts to detect and apprehend
    violators of the United States' national security and criminal laws.” Id.
    The FBI represents that it protected three catagories of information under this Exemption.
    See id. ¶ 40–45. First, it withheld a classified intelligence file number “assigned to specific
    intelligence activities, including channelization and dissemination instructions.” Id. ¶ 41. These
    “individual file numbers are assigned by FBIHQ and field offices and contain a numerical
    characterization of the investigation type, geographical prefix or the originating office, and a
    chronological number assigned to a specific investigation or activity.” Id. ¶¶ 19, 41. Seidel
    explains that disclosure of this file number would allow “adversaries to attribute any information
    released from records containing such a file number to that particular investigation[,]” affording
    them the opportunity to ultimately “patch bits and pieces of information together until the
    [intelligence] activity is determined . . . [,]severely limiting its use.” Id. ¶ 42. Moreover, he states
    that such identification
    “will inform adversaries of the possible range of the FBI's intelligence
    capabilities, as well as the probable intelligence the FBI has gathered, or
    can collect, concerning them . . . [,]provid[ing] violators of the United
    States’ national security laws with a means of avoiding lawful regulations
    by potentially initiating countermeasures . . . [,][thus] making future
    operations more difficult, and compromising other ongoing planned
    intelligence operations.”
    Id.
    Additionally, the FBI withheld “classified information concerning the character and title
    of the case for a specific type of intelligence activity directed at a specific target of national security
    interest.” Id. ¶ 43. Seidel explains that such disclosure risks identifying a particular investigation
    16
    and its “nature, scope, or thrust . . . [and] the manner of acquisition of the intelligence information.”
    Id.
    Finally, the FBI withheld information that could identify the targets of an investigation.
    See id. ¶ 44. Seidel represents that such disclosure would “provide a description of an intelligence
    source's penetration of a specific target of national security during a specific time period[,]” thus
    allowing (1) “hostile individuals or foreign governments to appraise the scope, focus, location,
    target, and capabilities of the FBI’s intelligence-gathering methods and activities,” (2) “hostile
    agents to devise countermeasures to circumvent these intelligence activities or methods and render
    them useless[,]” and (3) disruption to “the FBI’'s intelligence­ gathering capabilities.” Id. ¶ 45.
    Based upon consideration of all of this information, the Court finds that the FBI has offered
    sufficient factual detail for the Court to conclude that the categories of information withheld under
    Exemption 1 may be classified according to EO 13526, and that it was properly classified pursuant
    to that Order. In fact, Seidel actually describes the withheld information in more detail than
    required under Exemption 1. See, e.g., Nat'l Sec. Counselors v. CIA, 
    960 F. Supp. 2d 101
    , 166
    (D.D.C. 2013) (“Although many details of these two documents remain unknown, the
    [government]'s declaration plausibly establishes that the withheld information relates to sensitive
    operations within the Intelligence Community, the substance of which is properly classified in the
    interest of national security. That is sufficient to grant summary judgment.”); DiBacco v. Dep't of
    the Army, 
    983 F. Supp. 2d 44
    , 61 (D.D.C. 2013) (finding that, where the government has provided
    a “reasonable level of specificity that the information at issue was properly classified[,]”
    information was properly withheld under Exemption 1), aff’d in relevant part, 
    795 F.3d 178
    , (D.C.
    17
    Cir. 2015). Accordingly, and with no challenge from the plaintiff, the Court concludes that the FBI
    properly withheld this information pursuant to Exemption 1. 
    2 B. 5
     U.S.C. § 552(b)(3) (“Exemption 3”):
    Pursuant to Exemption (b)(3), an agency may withhold information “specifically exempted
    from disclosure by statute,” 
    5 U.S.C. § 552
    (b)(3), so long as the statute:
    (A)(i) requires [withholding] from the public in such a manner as to leave
    no discretion on the issue; or (ii) establishes particular criteria for
    withholding or refers to particular types of matters to be withheld; and
    (B) if enacted after the date of enactment of the OPEN FOIA Act of 2009,
    specifically cites to this paragraph.
    
    Id.
     To prevail on summary judgment based on this Exemption, the FBI “need only show that the
    statute claimed is one of exemption as contemplated by Exemption [(b)(3)] and that the withheld
    material falls within the statute.” Larson, 
    565 F.3d at 865
     (citation omitted). Notably, “the Court
    must defer to the FBI's determination, because [t]he judiciary ‘is in an extremely poor position to

    Regarding Exemption 1, the FBI also concomitantly invoked 
    5 U.S.C. § 552
    (b)(7)(A)
    (“Exemption 7(A)”)––which protects from disclosure records or information compiled for law
    enforcement purposes, to the extent that the production of that information could reasonably be
    expected to interfere with enforcement proceedings––see 
    id.,
     in redacting the “FBI file number,
    scope, nature, and target of a pending investigation because it would reveal publicly unknown
    information concerning pending enforcement procedures.” MSJ Mem. at 11 n.2; Seidel Decl. ¶
    71; VI at 1–2, 9 (also withholding in part, pursuant to Exemption 7(A), Bates Nos. 42, 46, 49, 53,
    57, 60, 64, 66, 364, 368, 372, 376, 379, 383, 386, 390, and 395). While the Court is satisfied that
    these redactions were properly made under Exemption 1, it notes that § 552(b)(7)(A) applies
    equally to the withheld information. See Shapiro v. Dep’t of Justice, No. 12-cv-313, 
    2020 WL 3615511
    , at *16–*18 (D.D.C. July 2, 2020) (finding that the FBI properly withheld information
    pursuant to Exemption 7(A), derived from “closed” law enforcement files, because the FBI
    expressed concerns about “overlap” with other pending enforcement proceedings, and it “reviewed
    all documents with an eye toward the so-called ‘mosaic’ effect[,]” by which “an individual piece
    of intelligence information, much like a piece of jigsaw puzzle, may aid in piecing together other
    bits of information even when the individual piece is not of obvious importance in itself.”) (quoting

    Here, the FBI has exempted information pursuant to § 102A(i)(1) of the National Security
    Act of 1947, see Seidel Decl. ¶¶ 46–50; VI at 1–10 (withholding in part Bates Nos. 1–376, 379–
    83, 386–411), which requires the Director of National Intelligence (“DNI”) to “protect from
    unauthorized disclosure intelligence sources and methods[,]” 
    50 U.S.C. § 3024
    (i)(1). The plaintiff
    has not challenged the FBI’s use of Exemption 3.
    “The DNI has delegated enforcement of this National Security Act mandate to the heads
    of the 17 agencies that constitute the Intelligence Community,” Elec. Privacy Info. Ctr., 296 F.
    Supp. 3d at 121 (internal quotation marks, citation, and alterations omitted), and the FBI is one of
    those delegees, see 
    50 U.S.C. § 3003
    (4)(H). There can be no “dispute that the National Security
    Act satisfies the second criterion mentioned above because” it was enacted before the OPEN FOIA
    Act of 2009, see 
    id.,
     and it ‘refers to particular types of matters to be withheld’—namely,
    ‘intelligence sources and methods.’” Leopold v. CIA, 
    106 F. Supp. 3d 51
    , 57 (D.D.C. 2015)
    (quoting ACLU, 
    628 F.3d at 619
    ); see Sims, 471 U.S. at 167 (explaining that the “conclusion [that
    the National Security Act is a withholding statute] is supported by the plain meaning of the statute,
    by the legislative history of the FOIA, and by every federal court of appeals that has considered
    the matter”); DiBacco v. U.S. Army, 
    795 F.3d 178
    , 197 (D.C. Cir. 2015) (noting that the plaintiff
    “does not dispute, nor could she, that Section 3024(i)(1) is a valid Exemption 3 statute”).
    19
    Having found that the FBI has met the second element, 3 the Court considers whether it has
    met the first element; i.e., it must determine whether the FBI’s withholdings “satisfy the criteria
    of the exemption statute.” Fitzgibbon, 911 F.2d at 761. The Court finds the answer to that question
    to be in the affirmative. The FBI has invoked Exemption 3, largely in conjunction with Exemption
    1 (and with 
    5 U.S.C. § 552
    (b)(7)(E), discussed below), to protect information that, as already
    determined above, concerns intelligence activities and methods relating to the underlying
    investigation. See Seidel Decl. ¶¶ 37–40, 50. Seidel’s Declaration sufficiently explains that
    Exemption 3 applies, namely, because the information withheld from the FBI’s internal documents
    could reasonably be expected to lead to unauthorized disclosure of intelligence sources or methods.
    See 
    id.
     ¶¶ 47–50; see also Shapiro v. Dep’t of Justice, 
    37 F. Supp. 3d 7
    , 27 (D.D.C. 2014).
    Therefore, the Court finds that the information was properly withheld under Exemption 3.
    C. 
    5 U.S.C. §§ 552
    (b)(6), (b)(7)(C) (“Exemption 6 and 7(C)”)
    The FBI invokes FOIA Exemptions 6 and 7(C) for many of its withholdings. See Seidel
    Decl. ¶¶ 53–69. “[B]ecause the Court concludes that the FBI's withholding decisions [were]
    justified under the standard imposed under Exemption 7(C), it need not reach the question of
    whether the FBI's withholdings are independently justified under Exemption 6.” Schoenman v.
    3
    As noted above, qualifying statutes under 
    5 U.S.C. § 552
    (b)(3)(A)(ii) may refer to either
    “particular types of matters to be withheld[,]” or to “particular criteria for withholding”
    information, see 
    id.
     Statutes that fall into the latter category require “a formula whereby the
    administrator may determine precisely whether disclosure in any instance would pose the hazard
    that Congress foresaw in the disclosing of the information[,]” and if the agency withholds that
    information under Exemption 3, and the requester challenges that withholding, a court must review
    whether the agency “followed the particular criteria established. . .” in withholding that
    information. See Pub. Citizen, Inc. v. Mineta, 
    444 F. Supp. 2d 12
    , 17–18 (D.D.C. 2006) (quoting
    Am. Jewish Congress v. Kreps, 
    574 F.2d 624
    , 628–29 (D.C. Cir. 1978)) (internal quotation marks
    omitted), aff’d, 
    533 F.3d 810
     (D.C. Cir. 2008). Because § 102A(i)(1) falls into the former
    category––i.e., referring to the types of matters to be withheld, see 
    5 U.S.C. § 552
    (b)(A)(i), the
    Court need not conduct such an assessment. See Ass’n of Ret. R.R. Workers, Inc. v. U.S. R.R.

    2012 WL 3244009
     (D.C. Cir. Jul. 31, 2012). Accordingly, the Court will only conduct an analysis
    under Exemption 7(C).
    First, to invoke any subsection of § 552(b)(7), a threshold test must first be satisfied.
    Exemption 7 protects from disclosure “records or information compiled for law enforcement
    purposes[.]” 
    5 U.S.C. § 552
    (b)(7); see Abramson, 456 U.S. at 622. In assessing whether records
    were compiled for law enforcement purposes, the “focus is on how and under what circumstances
    the requested files were compiled, and whether the files sought relate to anything that can fairly
    be characterized as an enforcement proceeding.” Jefferson v. Dep’t of Justice, 
    284 F. 3d 172
    , 176–
    77 (D.C. Cir. 2002) (citations and internal quotations omitted).
    The FBI is, by definition, a criminal investigatory and regulatory law enforcement agency
    within the Department of Justice. See 
    28 U.S.C. § 531
     (“The Federal Bureau of Investigation is in
    the Department of Justice.”); 
    id.
     §§ 533–35, 538–540D (listing the many criminal investigatory
    and regulatory duties of the FBI and its officials). Seidel has stated that all the responsive records
    withheld pursuant to Exemption 7 were compiled for law enforcement purposes. Seidel Decl. ¶
    25. Additionally, the plaintiff’s own purpose for filing this action is rooted in his express interest
    in criminal investigation records. See Compl. ¶¶ 5, 7–12; FOIA Request; see also Blackwell v.
    FBI, 
    646 F. 3d 37
    , 40 (D.C. Cir. 2011) (finding that, where the plaintiff sought records relating to
    a criminal investigation and prosecution, it was “quite obvious[]” that the records were compiled
    for law enforcement purposes); Roberts v. FBI, 
    845 F. Supp. 2d 96
    , 103 (D.D.C. 2012) (same).
    Having satisfied its threshold burden, the Court therefore concludes that the responsive FBI
    records were compiled for law enforcement purposes.             The Court must then address the
    21
    applicability of the cited subsections of Exemption 7. See 
    5 U.S.C. § 552
    (b)(7); see also
    Abramson, 456 U.S. at 622.
    Exemption 7(C) protects from disclosure records compiled for law enforcement purposes
    to the extent that their disclosure “could reasonably be expected to constitute an unwarranted
    invasion of personal privacy.” 
    5 U.S.C. § 552
    (b)(7)(C). In assessing this question, a court must
    balance the privacy interests in nondisclosure against the public interest in “shed[ding] light on an
    agency's performance of its statutory duties.” DOJ v. Rept’s Comm. for Freed. of Press, 
    489 U.S. 749
    , 773 (1989). In other words, the proper application of “privacy exemptions [6 and 7(C)] turns
    on a balance of the individual's right of privacy against the basic policy of opening agency action
    to the light of public scrutiny.” CEI Wash. Bureau, Inc. v. DOJ, 
    469 F.3d 126
    , 128 (D.C. Cir. 2006)
    (citation and internal quotation marks omitted). Thus, when a requester seeks such information,
    an agency must conduct a balancing test to determine if releasing the information “could
    reasonably be expected to constitute an unwarranted invasion of personal privacy[,]” 
    id. at 127
    (quoting 
    5 U.S.C. § 552
    (b)(7)(C)), by balancing “the individual's right of privacy against the basic
    policy of opening agency action to the light of public scrutiny[,]” 
    id. at 128
     (citation omitted). It
    is this balancing test and “not the nature of the files in which the information was contained [that]
    limit[s] the scope of the exemption.” Nat’l Ass'n of Home Builders v. Norton, 
    309 F. 3d 26
    , 33
    (D.C. Cir. 2002).
    Here, under Exemption 7(C), the FBI withheld names and other identifying information
    of: (1) FBI personnel and staff, (2) local law enforcement personnel and staff, (3) third parties who
    assisted the investigation by providing information, (4) third parties of investigative interest, (5)
    third parties “merely mentioned,” (6) third party victims, and (7) non-FBI government personnel.
    See Seidel Decl. ¶¶ 53–69; see FBI VI at 1–10 (withholding in part Bates Nos. 1–148, 152–82,
    22
    184–411). For the reasons explained below, the Court finds that the FBI was justified in its reliance
    on Exemption 7(C).
    Disclosure of the personal information of law enforcement personnel and staff (both federal
    and local), third parties who assisted the FBI in its investigation, third parties of investigative
    interest, third parties mentioned, and non-FBI federal government personnel, see Schoenman, 
    763 F. Supp. 2d at 198
     (finding all of these categories of information to be exempt under Exemption
    7(C)), as well as third party victims, see Bartko v. Dep’t of Justice, 
    898 F.3d 51
    , 72 (D.D.C. 2018)
    (finding the same as to third party victims); Sandoval v. Dep’t of Justice, 
    296 F. Supp. 3d 1
    , 18–
    19 (D.D.C. 2017) (same); Accurso v. FBI, No. 19-cv-2540, 
    2021 WL 411152
    , at *5–6 (D.D.C.
    Feb. 5, 2021) (same); Shapiro, 
    2020 WL 3615511
    , at *29–32 (same), is ordinarily improper as
    disclosure could put all such individuals at risk of a myriad of harms.
    Here, as required,
    [t]he FBI has described, plausibly and in considerable detail, the harms
    one might reasonably expect to flow from the public disclosure of such
    information, including: subjecting these individuals to unsolicited scrutiny
    and harassment from the media, the general public, and current and former
    investigatory targets; endangering the safety of individuals who have
    provided information in the course of an investigation; and impairing the
    effectiveness of investigative activities by compromising the identities of
    law enforcement personnel and deterring individuals from providing
    information in the future.
    Schoenman, 
    763 F. Supp. 2d at
    198–99; see Seidel Decl. ¶¶ 53–69. In the instances where the FBI
    employed Exemption 7(C), it weighed the adverse effects of the release of the information to the
    individuals involved and the benefit to the public that disclosure could be expected to provide,
    concluding that the interest in privacy was greater. See Schoenman, 763 F. Supp. 2d. at 199; see
    also Seidel Decl. ¶ 55. And “the FBI did not withhold identifying information where it was able
    to determine that [an] individual was deceased or was a high-ranking governmental official whose
    23
    activities may be of a greater public interest.” Schoenman, 
    763 F. Supp. 2d at 199
    ; see Seidel Decl.
    ¶ 56.
    These “representations suffice to establish ‘a reasonable likelihood’ that the disclosure of
    such information would result in an unwarranted invasion of personal privacy. Indeed, courts have
    repeatedly upheld identical withholdings.” Schoenman, 
    763 F. Supp. 2d at
    199 (citing Amuso v.
    Dep’t of Justice, 
    600 F. Supp. 2d 78
    , 94–97 (D.D.C. 2009); Voinche v. FBI, 
    412 F. Supp. 2d 60
    ,
    68–69 (D.D.C. 2006)). The FBI’s noted concerns significantly outweigh what little benefit the
    public may gain from knowing this information regarding its understanding of agency operations.
    See 
    id. at 198
    ; see also Nat'l Whistleblower Ctr. v. DHHS, 
    849 F. Supp. 2d 13
    , 28 (D.D.C. 2012)
    (same); Banks v. Dep’t of Justice, 
    813 F. Supp. 2d 132
    , 144 (D.D.C. 2011) (same); Lesar v. Dep’t
    of Justice, 
    636 F. 2d 472

    1996 WL 734142
     (D.C. Cir. Nov. 20,
    1996).
    The Court emphasizes that this protection generally extends to those even passingly
    mentioned in law enforcement records. See Schrecker v. Dep’t of Justice, 
    349 F. 3d 657
    , 661 (D.C.
    Cir. 2003) (collecting cases and recognizing this Circuit’s “decisions [which] have consistently
    supported nondisclosure of names or other information identifying individuals appearing in law
    enforcement records . . .”), because such third party information is “categorically exempt” from
    disclosure under Exemption 7(C), in the absence of an overriding public interest in its disclosure);
    Nat. Mag., Wash. Bureau v. Customs Service, 
    71 F. 3d 885
    , 894, 896 (D.C. Cir. 1995)
    (acknowledging the “obvious privacy interest” cognizable under Exemption 7(C) and extending
    this interest “to third parties who may be mentioned in investigatory files”); accord Fischer v.
    DOJ, 
    596 F. Supp. 2d 34
    , 46 (D.D.C. 2009).
    24
    The plaintiff nonetheless expresses suspicions that, where larger swaths of information are
    redacted under Exemption 7(C), namely, the redactions associated with third-party victims, “[i]t
    is unlikely” that the bulk of it could be “inextricably intertwined with personally identifying
    information.” See Pl.’s Opp’n at 6. But the plaintiff fails to recognize that, on nearly every page
    where he has challenged the use of Exemption 7(C), the FBI also applied additional exemptions,
    largely, Exemption 7(D), see VI at 1–10; Opp’n Ex. B; Seidel Decl. ¶¶ 75–77. And as discussed
    below, Exemption 7(D) certainly justifies this type of larger “block-redaction.” See Comp. Prof'ls
    for Soc. Resp. v. Secret Serv., 
    72 F.3d 897
    , 905 (D.C. Cir. 1996); 
    5 U.S.C. § 552
    (b)(7)(D). Because
    all the plaintiff’s arguments regarding these records are predicated on his misconception that
    Exemption 7(C) was used to redact the descriptions of the shooters, they all are all equally
    defective.
    For example, the plaintiff references Bates Nos. 297–98, which contains some block
    redactions, and he argues that they must contain information apart from personal identifiers that
    are subject to Exemption 7(C). See Pl.’s Opp’n at 25; Surreply at 17–19; Opp’n Ex. B at Bates
    Nos. 297–98. However, those block redactions are also made pursuant to Exemption 7(D), see
    Opp’n Ex. B at Bates Nos. 297–98; Seidel Decl. ¶¶ 75–77, and as noted above, it renders the entire
    “block” exempt, thus making any segregation of the material impossible.
    The plaintiff’s remaining arguments are similarly not cognizable. He focuses inordinately
    on the FBI’s assertion that third-party victims may be forced “to relive traumatic events” if their
    identities were released. See Surreply at 19–23; Pl.’s Opp’n at 6–7, 34–42; Seidel Decl. ¶ 64. In
    doing so, the plaintiff again insists, without basis, that the descriptions of the shooters were
    redacted under Exemption 7(C), and argues that release of the that information should not cause a
    victim trauma––even though the FBI never made such a contention. See Surreply at 19–23; Pl.’s
    25
    Opp’n at 6–7, 34–42. As an example, he discusses a victim (also a confidential source), who
    provided information regarding one of the perpetrator’s behaviors immediately before and after
    the shooting. See Surreply at 18; Pl.’s Opp’n at 24–25; Opp’n Ex. B at Bates Nos. 297–98. He
    argues that because this information does not describe the shooting itself, it should not cause the
    victim trauma, and therefore, should be released. See Surreply at 18; Pl.’s Opp’n at 24–25.
    But the descriptions of the perpetrators, provided by this individual and others were, in
    fact, largely redacted pursuant to Exemption 7(D), not Exemption 7(C). See Opp’n Ex. B at Bates
    Nos. 297–98; Seidel Decl. ¶¶ 75–77. However, even if they were redacted under Exemption 7(C),
    the plaintiff cites to no authority to support his speculative argument. Thus, it is completely unclear
    why proximate details regarding the event, whether antecedent or subsequent, would somehow be
    immune from causing a victim trauma.
    Moreover, trauma is not the only basis for preventing an unwarranted invasion of a victim’s
    personal privacy. For instance, as noted by the FBI, the “witnesses’ and victims’ recounting of
    these events was provided for use by law enforcement in an official investigation, and not for
    public consumption. Releasing these individuals’ identities in the context of these investigative
    records would cause unsolicited and unnecessary attention to be focused on these individuals and
    their families.” Seidel Decl. ¶ 64. Victims are fundamentally entitled to protection of their
    “cognizable privacy interest” for many reasons, see Accurso, 
    2021 WL 411152
    , at *5 (citing
    Schrecker, 
    349 F.3d at 661
    ) (quotation omitted), and that reason need not be profoundly traumatic;
    indeed, it can be as simple as seeking to prevent their mere association with the criminal event, see
    
    id.
     (citing Dunkelberger v. Dep't of Justice, 
    906 F.2d 779
    , 781 (D.C. Cir. 1990) (“Exemption 7(C)
    takes particular note of the strong interest of individuals . . . in not being associated unwarrantedly
    with alleged criminal activity.”) (citation and internal quotation marks omitted)); see also Nishnic
    26
    v. Dep’t of Justice, 
    671 F. Supp. 776
    , 789–90 (D.D.C. 1987) (collecting cases and holding that
    Exemption 7(C) “contemplates ‘invasions’ of widely varied types[,]” including potential
    embarrassment, reputational harm, annoyance, harassment, discomfort, or stigma).
    Finally, and as noted earlier, see § III (C) at 24, the D.C Circuit instructs “categorically
    that[,] unless access to” personal identifiers “of private individuals appearing in files within the
    ambit of Exemption 7(C) is necessary in order to confirm or refute compelling evidence that the
    agency is engaged in illegal activity, such information is exempt from disclosure[,]” SafeCard
    Srvs., Inc. v. SEC, 
    926 F.2d 1197
    , 1206 (D.C. Cir. 1991). The plaintiff has not advanced or
    presented any public interest with respect to the information sought––let alone anything to suggest
    the FBI’s engagement in illegal activity. In fact, in his Surreply, he does not challenge the FBI’s
    position that he has ostensibly failed to demonstrate a public interest. See Surreply at 19. He
    instead argues that he is under no such obligation because Exemption 7(C) was improperly applied
    to the descriptions of the shooters, a topic that, if released, would be non-traumatic to the reporting
    witnesses, and would make any privacy intrusion de minimis. See Surreply at 19–23; see also Pl.’s
    Opp’n at 6–7, 34–42. But once again, these descriptions were redacted, in large part, pursuant to
    Exemption 7(D), not Exemption 7(C). See VI at 1–10; Opp’n Ex. B; Seidel Decl. ¶¶ 75–77. And
    to the extent the plaintiff actually challenges the FBI’s redactions of the victim’s personal
    identifying information withheld under Exemption 7(C), and even if that redacted information also
    included descriptions of the perpetrators or the incident itself, the FBI has justified those
    withholdings. See Lesar, 636 F. 2d at 487; see also Steinberg v. Dep’t of Justice, 
    179 F.R.D. 357
    ,
    364 (D.D.C. 1998) (entering summary judgment on behalf of the government as to its redactions
    within “certain documents that describe the contents of an informant's interview with the
    government,” under Exemption 7(C) because “[i]t is understandable how the public disclosure of
    27
    highly confidential details about terrorist activities might be traced to particular individuals.”),
    aff’d, No. 98-5465, 
    1999 WL 1215779
     (D.C. Cir. Nov. 5, 1999). Seidel’s Declaration is specific
    as to what information is being withheld and why the privacy interests outweigh any public
    interest; its representations are neither conclusory nor vague, nor is there any evidence of bad faith,
    and the plaintiff has presented no evidence to the contrary. See id.; see also Seidel Decl. ¶¶ 53–
    69.
    For all of these reasons, the Court concludes that the FBI’s withholdings were proper under
    Exemption 7(C), and that it released all segregable information as it relates to this Exemption.
    D. 
    5 U.S.C. § 552
    (b)(7)(D) (“Exemption 7(D)”)
    As discussed above, the FBI also relies on Exemption 7(D) for some of its withholdings.
    See Seidel Decl. ¶¶ 72–77; VI at 1–10 (withholding in part Bates Nos. 1–11, 16–68, 71–148, 152–
    182, 184–374, 379–82, 386–99, 401–11). Exemption 7(D) protects “records or information
    compiled by criminal law enforcement authorities in the course of criminal investigations if their
    release could reasonably be expected to disclose the identity of, as well as information provided
    by, a confidential source.” Comp. Prof'ls, 
    72 F.3d at 905
    ; see 
    5 U.S.C. § 552
    (b)(7)(D).
    Here, the FBI withheld the names, identifying personal data, and the investigative
    information provided by sources who received implied assurances of confidentiality from the
    agency. See Seidel Decl. ¶¶ 75–77. Indeed, “[a] source is confidential within the meaning of
    [E]xemption 7(D) if the source provided information under an express assurance of confidentiality
    or in circumstances from which such an assurance could be reasonably inferred.” Williams v. FBI,
    
    69 F.3d 1155
    , 1159 (D.C. Cir. 1995) (quotation omitted) (emphasis added). There is no general
    “presumption that a source is confidential within the meaning of Exemption 7(D) whenever the
    source provides information [to a law enforcement agency] in the course of a criminal
    28
    investigation.” DOJ v. Landano, 
    508 U.S. 165
    , 181 (1993). Rather, a source’s confidentiality
    must be determined on a case-by-case basis. 
    Id.
     at 179–80. “[T]he focus should always be on
    whether the source of the information spoke with the understanding of confidentiality, not whether
    the document is generally thought to be confidential.” Brown v. FBI, 873 F. Supp. 2d. 388, 406
    (D.D.C. 2012) (citing Landano, 
    508 U.S. at 172
    ).
    The FBI protected these sources, who were under the impression that their communications
    were confidential, due to the “critical information [that they conveyed] regarding the San
    Bernardino shooting. These individuals provided specific, detailed information that is singular in
    nature––i.e., only a few individuals would be privy to such information[,]” including “locations in
    or near the building where the shooting occurred and their specific actions during the shooting.”
    Seidel Decl. ¶ 76. Furthermore, many of these sources “were coworkers of one of the investigative
    subjects and some sources interacted with this coworker the day of the shooting.” 
    Id.
     ¶¶ 75–76.
    Seidel also explains that the “highly violent nature of the mass shooting described in the records
    at issue attests to the fact that anyone cooperating with a law enforcement investigation concerning
    this terrorist attack would want and expect confidentiality[,]” and “[a]lthough the suspected
    shooters are deceased, like­minded individuals or others sympathetic to the San Bernardino
    suspects could seek to deter a source's cooperation with law enforcement through reprisal[,]” or to
    seek retribution against the source and their family, by engaging in acts of harassment, defamation,
    threats, or violent acts, including murder. Id. ¶ 76. Put differently, the information they provided
    is “singular in nature,” and just like their names and contact information, such disclosure could
    easily expose like their identities. See id. ¶¶ 73, 76.
    Finally, the FBI maintains that it “would forever eliminate that source as a future means of
    obtaining information[,]” and exposure would create a “chilling effect on the activities and
    29
    cooperation of other sources[,]” thus undermining “the FBI's most important means of collecting
    information and could thereby severely hamper law enforcement efforts to detect and apprehend
    individuals engaged in the violation of federal criminal laws.” Id. ¶ 74.
    Given these detailed sworn representations, the Court is satisfied that the sources received
    implied confidentiality, and that Exemption 7(D) was properly invoked. The Court takes into
    account all of the extant circumstances in assessing whether these sources plausibly received
    implied assurances, see Roth, 642 F.3d at 1184, including “the nature of the crime and the source's
    relation to it[,]” Landano, 
    508 U.S. at 179
    , and finds it noteworthy that courts in this Circuit have
    consistently recognized the violence and risk of retaliation attendant to “disclosure of the identities
    of or information provided by confidential sources . . . in circumstances where the subject of the
    investigation is known to have committed serious or violent offenses and where the sources are at
    risk of retaliation, harassment or bodily harm.” Holt v. Dep’t of Justice, 
    734 F. Supp. 2d 28
    , 46
    (D.D.C. 2010) (affirming the protection of source information arising from a murder investigation,
    due to implied confidentiality under Exemption 7(D)) (citations omitted); see Williams, 
    69 F.3d at
    1159–60 (concluding that sources who spoke to the FBI regarding a nationalist organization
    “suspected . . . of committing . . . rebellion or insurrection, seditious conspiracy, and advocating
    the overthrow of the government,” and which demonstrated its “willingness to use violence against
    its enemies,” did so under an implicit assurance of confidentiality); Pinson v. Dep’t of Justice, 
    177 F. Supp. 3d 56
    , 89 (D.D.C. 2016) (affirming withholding of information regarding sources with
    implied confidentiality under Exemption 7(D) where plaintiff sought records regarding the law
    enforcement investigation of a “shooting death”).
    Indeed, and as here, singular information provided to assist “[i]nvestigations into domestic
    terrorism have been recognized as a sort of criminal investigation where an implicit grant of
    30
    confidentiality will be found.” Jud. Watch, Inc. v. Reno, No. 00-cv-0723,

    under Exemption 7(D) because the “crime at issue involve[d] domestic terrorism and the use of
    explosives[,]” which are “certainly serious or violent crimes that weigh in favor of a finding of
    [implied] confidentiality[,]” and because the sources provided “singular information” during the
    investigation) (internal citations and quotation marks omitted); Owens v. Dep't of Justice, No. 04-

    , at *11 (D.D.C. Mar. 9, 2007) (identifying investigations of terrorist
    attacks as a circumstance that warrants an inference of implied source confidentiality under
    Exemption 7(D)).
    In response, the plaintiff argues that the confidential sources’ descriptions of the shooters,
    where redacted under Exemption 7(D), should be released because that particular information
    cannot be used to identify the confidential sources. See Pl.’s Opp’n at 8; Surreply at 13–16. He
    speculates that the information that the FBI already released to him put these sources at greater
    risk than revealing the descriptions of the shooters, which he claims has “no rational link” to the
    sources’ identities. See Pl.’s Opp’n at 8–11; Surreply at 13, 15–16. However, “the availability of
    Exemption 7(D) depends not upon the factual contents of the document sought, but upon whether
    the source was confidential and the information was compiled during a criminal investigation.”
    Weisberg v. Dep’t of Justice, 
    745 F.2d 1476
    , 1492 (D.C. Cir. 1984) (citing Lesar, 636 F.2d at 492);
    Blanton, 
    63 F. Supp. 2d at 48
     (“[T]he relevant inquiry is ‘not whether the requested document is
    31
    of the type that the agency usually treats as confidential, but whether the particular source spoke
    with an understanding that the communication would remain confidential.’”) (quoting Landano,
    
    508 U.S. at 172
    ) (emphasis in original); Parker v. Dep't of Justice, 
    934 F.2d 375
    , 380 (D.C. Cir.
    1991) (holding that “once the agency receives information from a confidential source during the
    course of a legitimate criminal investigation . . . [,] all such information obtained from the
    confidential source receives protection”) (citing Lesar, 636 F.2d at 492 & n.114). Here, there is
    no question––nor is there any dispute from the plaintiff––that the FBI’s sources were confidential,
    and that the information was compiled during a criminal investigation. See, e.g., Seidel Decl. ¶¶
    73–77. Consequently, the content at issue, namely, the descriptions of the shooters, is irrelevant
    to the analysis of the propriety of the withholdings under Exemption 7(D).
    The plaintiff also argues that the sources’ descriptions of the shooters should be released
    because the incident was “a widely known event at a widely known time and place, publicized by
    the national news, and acknowledged by the general public.” Pl.’s Opp’n at 9. But, assuming the
    plaintiff’s representations to be true, it is of no consequence. “[E]ven assuming, arguendo, that
    some of the withheld information has appeared in the press, the nondisclosure is proper because a
    disclosure from an official source of information previously released by an unofficial source would
    confirm the unofficial information and therefore cause harm to third parties.” Fisher v. Dep’t of
    Justice, 
    772 F. Supp. 7
    , 12–13 (D.D.C. 1991), aff’d, 
    968 F.2d 92
     (D.C. Cir. 1992).
    The plaintiff also relies on the purported public interest in disclosure of this information,
    see Pl.’s Opp’n at 10–11, and cites to Dep’t of State v. Ray, 
    502 U.S. 164
     (1991), see Opp’n at 9–
    11. But the plaintiff’s reliance on that case is misplaced because, in Ray, the Supreme Court found
    unanimously that personal information concerning refugees returned to Haiti was indeed properly
    withheld from release. See Ray, 502 U.S. at 179. Moreover, even if the holding in Ray somehow
    32
    worked to the plaintiff’s advantage, that case is inapposite to the circumstances in this matter. In
    Ray, the redacted information came from voluntary interviewees, not government sources, and the
    redactions were made pursuant to Exemption 6, not Exemption 7(D), see id. at 170–71, which
    require different standards of analysis. Indeed, the plaintiff’s “appeal to a public interest in
    disclosure is unavailing as a matter of law[,]” Jud. Watch, 
    2001 WL 1902811
    , at *9, because
    Exemption 7(D) does not require any balancing of the public interest, see 
    id.
     (citing Dow Jones &
    Co. v. Dep't of Justice, 
    917 F.2d 571
    , 575–76 (D.C. Cir. 1990)). Consequently, the Court finds
    the plaintiff’s arguments unavailing.
    For all of these reasons, the Court finds that the FBI’s reliance on Exemption 7(D) is proper
    and finds no defect in the FBI’s segregability analysis arising therefrom.
    E. 
    5 U.S.C. §§ 552
    (b)(7)(E) (“Exemption 7(E)”)
    Finally, the FBI invokes Exemption 7(E), see Seidel Decl. ¶¶ 78–88, which protects from
    disclosure law enforcement records, “to the extent that the production of such law enforcement
    records or information . . . 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[,]”
    
    5 U.S.C. § 552
    (b)(7)(E). The plaintiff does not express opposition to the FBI’s use of Exemption
    7(E).
    Under this Exemption, this Circuit has “set a relatively low bar for the agency,” requiring
    it only to “demonstrate logically how the release of the requested information might create a risk
    of circumvention of the law.” Blackwell, 646 F.3d at 42. Any information that “could increase the
    risks that a law will be violated” is protected from disclosure. Mayer Brown LLP v. IRS, 
    562 F.3d 1190
    , 1193 (D.C. Cir. 2009); see Fisher, 
    772 F. Supp. at 12
     (upholding the FBI's decision to
    33
    withhold information about law enforcement techniques where disclosure would impair
    effectiveness and, within the context of the documents, could alert subjects of investigations “about
    techniques used to aid the FBI”). Here, the FBI easily meets this low bar.
    The FBI withheld four categories of information under Exemption 7(E), see Seidel Decl.
    ¶¶ 80–88, all of which the Court finds to be proper. First, it withheld “sensitive file numbers[,]”
    Seidel Decl. ¶¶ 80–83; VI at 1–10 (withholding in part Bates Nos. 1–42, 46, 49, 53, 57, 60, 64, 66,
    69–115, 119, 123–48, 152–82, 184–286, 288–364, 368, 372, 376, 379, 383, 386, 390, 395, 399–
    411), which consist of (1) classification numbers, (2) two-letter internal office codes, and (3)
    numbers assigned to the underlying “investigative initiatives[,]” Seidel Decl. ¶¶ 80–82. Seidel
    explains that releasing these confidential identifiers would reveal “the investigative interest or
    priority given to such matters.” Id. ¶ 80.
    More specifically, he indicates that public knowledge of the classification numbers in the
    context of the Inland investigation would expose “key non-public information about the FBI's
    investigative strategies and gathered evidence . . . [, and] information about non-public
    investigative techniques and procedures[,]” thus providing “criminals and foreign adversaries the
    ability to discern the types of highly sensitive investigative strategies the FBI is pursuing whenever
    such file classification numbers are present within these and other sensitive FBI investigative
    records.” Id. He also indicates that exposing the office codes
    would reveal critical information about where and how the FBI detected
    particular criminal behaviors or national security threats, and reveal key
    pieces about the FBI's non-public investigations or intelligence and
    evidence gathering sources and methods . . . [,][and] risk disclosing
    unknown FBI investigations or intelligence gathering initiatives, by
    revealing interests in varying areas of FBI investigative responsibility[,]
    [and its] failure to detect certain types of criminal behavior.
    34
    Id. ¶ 81. He further represents that, in doing so, criminals or would-be criminals in cities without
    associated originating office codes could “assume the FBI failed to locate any evidence of their
    wrongdoing, emboldening them to continue their activities, undeterred.” Id. And Seidel further
    represents that revealing the investigation numbers “would provide criminals and foreign
    adversaries with a tracking mechanism by which they can place particular investigations within
    the context of larger FBI investigative efforts,” because a wrongdoer could discern “how FBI
    investigations may be interrelated and when, why, and how the FBI pursued different investigative
    strategies[,]” which would allow them to see how “FBI allocates its limited investigative resources,
    how the FBI responds to different investigative circumstances, what the FBI knows[,] including
    when and how they obtained the knowledge, and if there are knowledge gaps in the FBI's gathered
    intelligence.” Id. ¶ 82.
    Given this detailed information, the FBI “demonstrate[s] logically how the release of the
    requested information might create a risk of circumvention of the law,” Blackwell, 646 F.3d at 42
    (internal quotation marks omitted), and it identifies the harms attendant to the disclosure of these
    file numbers. Therefore, the Court finds that these redactions are appropriate under Exemption
    7(E). See Poitras v. Dep’t of Homeland Security, 
    303 F. Supp. 3d 136
    , 159 (D.D.C. 2018)
    (affirming the defendant’s withholding of sensitive file numbers under Exemption 7(E)).
    Second, the FBI also protected an official “direct line” “non-public telephone number of
    an FBI employee.” Seidel Decl. ¶ 84; VI at 10 (withholding in part Bates No. 409). Seidel attests
    that such release would put the agency at risk for an attack on its secure communications by way
    of “spoofing,” and other acts of fraud, “to elicit sensitive information[.]” Seidel Decl. ¶ 84. He
    asserts that this disclosure could cause “substantial risks to the FBl's ability to carry out its mission
    effectively, could potentially decrease the FBI's effectiveness by devaluing public trust, and could
    35
    enable criminals to circumvent the law.” 
    Id.
     Considering the nature of the documents in which
    the telephone number was contained, together with Seidel’s specific representations regarding this
    redaction, the Court is satisfied that the FBI has demonstrated that this phone number could be
    used in furtherance of potential fraudulent acts, and could lead to disruption of the FBI’s activities,
    or to the harassment and intimidation of its officials. See Shapiro v. Dep’t of Justice, 
    78 F. Supp. 3d 508
    , 520 (D.D.C. 2015) (affirming the FBI’s redaction of an internal phone number under
    Exemption 7(E)).
    Third, the FBI withheld “database identifiers” under Exemption 7(E). Seidel Decl. ¶¶ 85–
    87; VI at 8 (withholding in part Bates Nos. 333–34). These identifiers correspond to “the identity
    of and query data from a sensitive non-public investigative database used for official law
    enforcement purposes by the FBI[,]” and Seidel identifies multiple ways in which disclosure of
    such information would aid criminals in acquiring “insight into the available tools and resources
    the FBI uses to conduct criminal and national security investigations[,]” and endanger the FBI's
    investigative function and effectiveness by, for example, “revealing exactly where the FBI is
    storing and obtaining valuable investigative data[,]” and rendering the FBI vulnerable to
    cyberattack. See 
    id.
     ¶¶ 85–86. Furthermore, release of the identifiers would “allow criminals who
    gain access to FBI systems insight into where they can go to discover what the FBI knows, how it
    gathered the information, and possible information regarding the FBI's investigative strategies[,]”
    and provide an “opportunity to corrupt or destroy information stored within these databases.” 
    Id.
    The FBI has thus met its low burden to show that this information was properly redacted under
    Exemption 7(E). See Kendrick v. FBI, No. 20-cv-2900, 
    2022 WL 4534627
    , at *8 (upholding the
    FBI’s withholding of database-related information under Exemption 7(E)) (citing Shapiro v. Dep’t
    of Justice, 
    393 F. Supp. 3d 111
    , 122 (D.D.C. 2019) (noting that courts “generally have affirmed
    36
    the withholding of information related to databases––metadata, codes, and structures––under
    Exemption 7(E) for risk of cyber-attack or data breach.”) (collecting cases)).
    Fourth, the FBI “protected the methods the FBI uses to collect and analyze information it
    obtains for investigative purposes.” Seidel Decl. ¶ 88; VI at 2–3, 9 (redacting in part Bates Nos.
    46, 49, 53, 57, 60, 64, 66, 115, 119, 364, 368, 372, 376, 379, 383, 386, 390, and 395). The Court
    agrees that the FBI properly withheld this information, as it relates to its investigative efforts of
    subjects of interest and their engagement in criminal activity. See Seidel Decl. ¶ 88. The FBI
    represents that releasing such information would, inter alia, “enable criminals to educate
    themselves about the techniques employed for the collection and analysis of information and
    therefore allow these individuals to take countermeasures to circumvent the effectiveness of these
    techniques and to continue to violate the law and engage in intelligence, terrorist, and criminal
    activities.” 
    Id.
     Thus, these withholdings were also proper under Exemption 7(E). See Kendrick,
    
    2022 WL 4534627
    , at *9 (holding same) (citing Shapiro v. Dep’t of Justice, 
    893 F.3d 796
    , 800
    (D.C. Cir. 2018) (holding same)).
    IV.     In Camera Review
    The plaintiff requests that the court conduct in camera review to determine the propriety
    of the redactions of the descriptions of the perpetrators, made under Exemption 6 and 7(C), and
    Exemption 7(D), specifically as it relates to their segregability. See Pl.’s Opp’n at 32–33; Surreply
    at 23–24. The FOIA authorizes the Court, at its discretion, to examine the contents of agency
    documents in camera. See 
    5 U.S.C. § 552
     (a)(4)(B). “In camera inspection may be appropriate in
    two circumstances: when agency affidavits are insufficiently detailed to permit meaningful review
    of exemption claims, and when evidence of agency bad faith is before the court.” Lam Lek Chong
    v. DEA, 
    929 F.2d 729
    , 735 (D.C. Cir. 1991). Neither situation is presented here. The FBI has
    37
    adequately described the segregability analysis it conducted, see Seidel Decl. ¶¶ 90–92, in
    combination with its Vaughn Index, and has provided sufficient justification for its redactions and
    withholdings under the exemptions it invoked. Moreover, there are no allegations or evidence in
    the record to suggest bad faith by the FBI. Consequently, the request for in camera review is
    denied. See Pinson, 
    177 F. Supp. 3d at 90
    .
    CONCLUSION
    For the foregoing reasons, the FBI’s Motion for Summary Judgment is granted. An Order
    consistent with this Memorandum Opinion will be issued contemporaneously.
