Vacated and remanded by published opinion. Judge LUTTIG wrote the opinion, in which Chief Judge WILKINSON and Judge MOTZ joined.
OPINION
The district court ordered the public release of appellee R. Keith Neely’s unre-dacted FBI file, rejecting the FBI’s attempted withholding of portions of Neely’s file under Exemptions 7(C) and 7(D) of the Freedom of Infоrmation Act, 5 U.S.C. § 552, and the FBI appeals. Because we conclude that the FBI may be entitled to *463 withhold significant portions of Neely s file under either Exemption 7(C), 7(D), or both, we vacate the judgment below and remand for further proceed-ings in the district court.
I.
R. Keith Neely, a federal prisoner, brought the present cоmplaint, seeking to enjoin the FBI to comply with his request under the Freedom of Information Act (FOIA) for “all information pertaining to [him]” that exists in the FBI’s files. J.A. 16. According to Neely, he needed the information to prove that a key government witness, Michael Giacolone, had perjured himself at Neely’s criminal trial. In response to the district court’s order to expedite the processing of Neely’s FOIA request, the FBI provided Neely with 796 of the 1,386 pages deemed “responsive” to Neely’s request. A significant number of these pages were heavily redacted.
Two months later, the district court held a hearing on Neely’s various procеdural and non-dispositive motions. Shortly before this January 8, 1999 hearing began, the FBI submitted a twenty-two-page affidavit on its own initiative explaining, in a general fashion, the reasons for its withholding and redaction of information in Neely’s file pursuant to various FOIA Exemptions. J.A. 190-209. Finding the affidavit to be too general and conclusory, the district court ordered the FBI to produce the entire file, unredacted, by January 22, for incamera review by the court. After reviewing the first 50 to 100 pages of each of the six packets of documents submitted by the FBI, most of which simply had only the conclusory notations “7(C)” or “7(D)” written on them, the district court on January 25 ordered thе entire unredacted file to be made available for inspection and copying in the clerk’s office on January 29, with the exception of those documents as to the withholding of which the FBI provided detailed, specific justifications. On January 28, we stayed the order pending appeal.
II.
The district cоurt was clearly frustrated with the FBI over its failure to provide reasoned and particularized explanations for its withholding of requested documents and we do not doubt that this frustration was warranted. Confining ourselves to the district court’s stated reasons for denying the FBI’s claimed Exemptions, however, it appears that the district court grounded its denial largely on the FBI’s failure to articulate the justification for its withholdings with sufficient specificity, a matter on which we are essentially in agreement with the district court and which we address below. It also appears, however, that the district court may have rested its denial at least in part on the belief that Exemptions 7(C) and 7(D) are unavailable if the responsive information is already publicly known or available through other sources. See, e.g., J.A. 315-16. To the extent that the district court’s denial rested on this belief, the district court was in error. As we explain more fully below, such public knowledge or availability does not necessarily foreclose application of either Exemption 7(C) or Exemption 7(D).
A.
Exemption 7(C), invoked by the FBI to justify the bulk of its withholdings, authorizes agencies to withhold “records or information compiled for law enforcement purposes, but only to the extent that the production of such'law enforcemеnt records or information [ ... ] could reasonably be expected to constitute an unwarranted invasion of personal privacy.” 5 U.S.C,§ 552(b)(7)(C).
In order to determine under Exemption 7(C) whether the production of responsive law enforcement records or information could “reasonably be expectеd to constitute an unwarranted invasion of personal privacy,” the public -interest in disclosure of the -responsive information
*464
must be weighed against the privacy interests in the information,
see United States Dep’t of Justice v. Reporters Committee for Freedom of the Press,
On the understanding that much of thе information the FBI wishes to withhold in this case under Exemption 7(C) consists of names and identifying information of FBI agents, other government employees, third-party suspects, and third parties mentioned or interviewed in the course of an investigation, the public interest in most, if not all, of the information would appear to be negligible. Correspondingly, there being no compelling allegation of agency corruption or illegality,
see SafeCard Services, Inc. v. Securities & Exchange Comm’n,
That Neely seeks this information to establish indirectly his own innocence does not alter the fact that there would appear to be no FOIA-cognizable public interest in such information. The innocence оf a particular defendant in a particular case “tell[s] us nothing about matters of substantive law enforcement policy that are properly the subject of public concern.” And, as the Supreme Court has made clear in no uncertain terms, “the identity of the requesting party” and “the purposes for which the request for information is made” by that party “ha[ve] no bearing on the merits of his or her FOIA request.”
Reporters Committee,
On the other side of the ledger from the likely negligible public interest in this withheld information, the FBI agents, government employees, third-party suspects, and other third parties mеntioned or interviewed in the course of the investigation have well-recognized and substantial privacy interests in the withheld information. Among other things, these individuals have
*465
a substantial interest in the -nondisclosure of their identities and their connection with particular investigations because of the potential for future hаrassment, annoyance, or embarrassment.
See, e.g., Halpern v. FBI,
As we noted, it appears that the district court may have discounted these privacy interests because the identities of some or all of the individuals had been publicly disclosed or were publicly available. To the extent that it did do so, this was in error. In
Reporters Committee,
the Supreme Court rejected the argument that the public availability of information
necessarily
renders nonexistent the privacy interests in that information protected by Exemption 7(C). There, for example, the Court rejected the claim that the privacy interests in the requested rap sheet “approaches zero” merely “[bjecause events summarized in [the] rap sheet [withheld under Exemption 7(C) ] ha[d] been previously disclosed to the public,”
id.
at 762-63,
Because the relevant privacy interests in the informatiоn withheld by the FBI in this case under Exemption 7(C) would seem to outweigh the relatively negligible public interest in the information, and because this case would appear to “fit[ ] into a genus in which the balance characteristically tips in one direction,”
Reporters Committee,
B.
Exemption 7(D) authorizes agencies to withhold
records or information compiled for law enforcement purposes, but only to the еxtent that the production of such law enforcement records or information [ ... ] could reasonably be expected to disclose the identity of a confidential source, including a State, local, or foreign agency or authority or any private institution which furnished information on a confidential basis, and, in the case of a record or information compiled by *466 criminal law enforcement authority in the сourse of a criminal investigation or by an agency conducting a lawful national security intelligence investigation, information furnished, by a confidential source.
5 U.S.C. § 552(b)(7)(D) (emphases added).
As with the district court’s denial of the FBI’s Exemption 7(C) withholding, it appears that the district court may have denied the FBI’s Exemption 7(D) withholding at least in part out of a belief that that Exemption, too, cannot be claimed to protect the identities of confidential sources whose identities have previously been disclosed. To the extent that the district court also denied the Exemption 7(D) withholding on this basis, it similarly erred. In
Radowich v. United States Att’y, District of Maryland,
Nor does public availability effect a waiver of the government’s rights under this Exemption. As our sister сircuits have held, the statute by its terms does not provide for such waiver. Rather, once the prerequisites of a “confidential source” and a record compiled “in the course of a criminal [or national security] investigation” are satisfied, Exemption 7(D) protects from disclosure “information furnished by [that] сonfidential source.”
See Parker v. Dep’t of Justice,
If on remand the district court finds that the documents (or portions thereof) in Neely’s file withheld solely under Exemption 7(D) do in fact, as the FBI claims, bear evidence “on their face” of “express assurances of confidentiality,” Appellant’s Reply Br. at 12, then the FBI would mosJ' likely be entitled to withhold suсh documents (or portions thereof) under Exemption 7(D). As the Court assumed in
Lan-dano,
“a source is confidential within the meaning of Exemption 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.’ ”
III.
Because “[t]he appellаte court is particularly ill-equipped to conduct its own investigation into the propriety of claims for nondisclosure,”
Van Bourg, Allen, Weinberg & Roger v. NLRB,
CONCLUSION
For the reasons stated, the district court’s order releasing Neely’s unredacted FBI file is vacated, and the case is remanded for further proceedings consistent with this opinion.
VACATED AND REMANDED
Notes
. Neely argues that the FBI's alleged knowledge of, and fаilure to prevent or disclose, the perjurious nature of Giacolone’s testimony at Neely’s criminal trial constituted agency illegality. However, at oral argument, Neely was unable to say that the FBI had encouraged or suborned Giacolone's alleged perjury, which Giacolone allegedly admitted to only after Neely was incarcerated. We find that Neely’s other allegations similarly fail to constitute compelling evidence of agency corruption or illegality.
. At oral argument, ' Neely suggested that
