Opinion for the Court filed by Circuit Judge ROGERS.
The main issue in this appeal is whether the district court abused its discretion in conducting an
in camera
inspection of documents requested under the Freedom of Information Act, 5 U.S.C. § 552 (1994) (“FOIA”), without first ordering the agency to produce a more detailed description of the withheld documents in accordance with
Vaughn v. Rosen,
I.
In 1984, John Spirko was convicted in a state court for the abduction and murder of Betty Jane Mottinger, the Postmaster of El-gin, Ohio. One alleged co-conspirator, Delaney Gibson, Jr., was also indicted, but has yet to be tried. According to the Postal Service, other suspects remain at large, and the agency’s criminal investigation remains open.
On March 6, 1992, Spirko requested access to documents held by the Postal Service concerning its investigation of the Mottinger murder. As subsequently explained in his court pleadings, he was evidently searching for exculpatory evidence that the Postal Service allegedly withheld at his trial. The requested records included information contained in the “desk file” of Inspector Paul M. Hartman, the case agent for the investigation, and forty pages of records referred to the Postal Service by the Federal Bureau of Investigation (“FBI”) for processing. After an initial determination by the agency and an administrative appeal by Spirko, the Postal Service eventually released approximately two hundred pages, some of which had been redacted to protect the identities of suspects, witnesses, and law enforcement officials. 1 The released documents included all forty pages from the FBI referral; however, the agency withheld the majority of Inspector Hartman’s desk file.
Thereafter, Spirko filed suit under the Freedom of Information Act for access to the remaining documents. The Postal Service moved for summary judgment, relying upon a declaration by Inspector Hartman that detailed the contents of his desk file and justified the withholding of certain documents under various exemptions to FOIA disclosure requirements.

Finding Inspector Hart
*995
man’s declaration inadequate, Spirko moved to compel the Postal Service to submit an index with more specific details regarding the nature and approximate content of the withheld documents, pursuant to
Vaughn v. Rosen,
Following in camera review, the district court granted the Postal Service’s motion for summary judgment on all but three pages. The court found that most of the pages were covered by Exemption 7(C), which exempts information compiled for law enforcement purposes that “could reasonably be expected to constitute an unwarranted invasion of personal privacy.” 3 5 U.S.C. § 552(b)(7)(C). These pages were “comprised of hand-written notes about suspects and law enforcement records, primarily in the form of ‘rap sheets,’ fingerprints, and photos.” The court also found that several pages had been properly withheld under Exemption 7(F), which covers documents whose release “could reasonably be expected to endanger the life or physical safety of any individual.” Id. § 552(b)(7)(F). Nevertheless, the district court concluded that the government had failed to sustain its claim under Exemption 7(D) that the release of three particular pages might “reasonably be expected to disclose the identity of a confidential source ... [or] information furnished by a confidential source,” id. § 552(b)(7)(D), and ordered the Postal Service to make a particularized showing “as to how release of [the] pages ... will either result in the disclosure of a confidential source or reveal information furnished by a confidential source.” Ultimately, the Postal Service released two of the pages in their entirety and the third in redacted form, and the district court upheld the redactions as proper.
Spirko moved to amend or alter the judgment, pursuant to Federal Rule of Civil Procedure 59(e), asserting that he could provide new evidence of wrongdoing by the Postal Service in the investigation of the Mottinger murder and his subsequent prosecution. Spirko claimed that the Postal Service had withheld exculpatory evidence from him during the course of his criminal trial, in violation of
Brady v. Maryland,
II.
Spirko’s primary contention on appeal is that the district court erred by conducting an
in camera
review of the withheld documents without first requiring a more detailed affidavit from the Postal Service. He maintains that an
in camera
inspection is not an adequate substitute for a sufficient
Vaughn
index,
see Schiller v. NLRB,
In 1974, Congress amended FOIA to authorize district courts to “examine the contents of’ requested records “in camera to determine whether such records or any part thereof, shall be withheld.” 5 U.S.C. § 552(a)(4)(B). This court has repeatedly explained that “[t]he decision whether to perform
in camera
inspection is left to the ‘broad discretion of the trial court judge.’ ”
Lam Lek Chong v. DEA
Spirko contends that the district court abused its discretion by resorting to
in camera
review so hastily. By inspecting the documents
in camera
instead of ordering the government to submit a properly detailed index, Spirko contends, the court risks relieving the government of its obligations under
Vaughn,
eliminating the adversary role of the requester in defining the nature of the documents sought, and placing an undue burden on judicial resources.
See Quinon,
Unlike the instant case, FOIA re-questers commonly appeal a district court’s
refusal
to inspect documents
in camera
despite the alleged insufficiency of the
Vaughn
index.
See, e.g., PEE, Inc. v. Dep’t of Justice,
With such broad discretion vested in the district court, this court has yet to identify particular circumstances under which
in camera
inspection would be
inappropriate,
*997
although several concerns counsel against hasty resort to
in camera
review:
“in camera
review should not be resorted to as a matter of course, simply on a theory that ‘it can’t hurt.’ ”
Quinon,
Consequently, this court has repeatedly observed that a district court should not undertake
in camera
review of withheld documents as a substitute for requiring an agency’s explanation of its claimed exemptions in accordance with
Vaughn. See, e.g., PHE, Inc.,
Here, the Postal Service submitted a declaration from the inspector in charge of the Mottinger investigation. Inspector Hartman’s declaration placed the withheld documents in three general categories: (1) suspect files, (2) letters from a confidential informant unrelated to the Mottinger case, and (3) fingerprints and palm prints of former suspects. Only the first category required further elaboration. According to Inspector Hartman’s declaration, the suspect files contained information pertaining to suspects and former suspects including
information supplied by local and state law enforcement agencies ..., narratives and computer generated printouts of criminal activity of former suspects, photographs of former suspects, criminal histories and descriptions of suspects and former suspects, an interview of a former suspect pertaining to other unrelated crimes, and inspectors’ notes containing information from state, local, and federal law enforcement agencies pertaining to suspects and former suspects.
All of the information contained in these documents pertained to unrelated crimes committed by suspects other than Spirko. In his declaration, Inspector Hartman claimed that these documents were exempt from disclosure under FOIA Exemptions 7(A), (C), (D) and (F) and discussed, in general terms, the reasons why the documents fell under each exemption. A subsequent affidavit filed by the Postal Service at the time of its in camera submission listed the specific page numbers of the documents completely withheld from Inspector Hartman’s desk file and the exemptions claimed for each page.
Under
Vaughn,
the government is required to provide a detailed index to the requester “itemizing each item withheld, the exemptions claimed for that item, and the reasons why the exemption applies to that
*998
item.”

Lykins,
Spirko’s objections to the district court’s decision to inspect the documents
in camera
are unconvincing. First, he characterizes Inspector Hartman’s affidavit as conclusory and vague, yet he does not indicate what more the Postal Service could have stated without revealing the information it sought to protect. Clearly, “there are occasions when extensive public justification would threaten to reveal the very information for which a FOIA exemption is claimed,” particularly in the context of law enforcement records.
Ly-kins,
Spirko also maintains that the district court should not have assumed the burden of reviewing the disputed documents
in camera.
The district court concluded, however, that its review of the withheld documents would not burden judicial resources; indeed, it stated that the alternative — further
Vaughn
indexing — would not advance the “just, speedy and inexpensive determination” of the case. Although the documents totaled 472 pages, the vast majority consisted of easily perused fingerprints, palm prints, photographs, and criminal “rap sheets” of suspects and former suspects. Only a few pages contained handwritten notes or telephone messages that could require careful review by the district court. Under the circumstances, the district court acted within its discretion in denying Spirko’s motion for further
Vaughn
indexing and proceeding instead to an
in camera
inspection of the documents.
Cf. Lykins,
III.
Spirko’s challenge to the district court’s finding that the bulk of the withheld documents had properly been withheld under Exemption 7(C) of FOIA merits only brief discussion. This court reviews
de novo
a “grant of summary judgment in favor of an agency which claims to have complied with FOIA,”
Nation Magazine v. United States Customs Serv.,
Under Exemption 7(C), which covers “records or information compiled for law enforcement purposes” whose disclosure “could reasonably be expected to constitute an unwarranted invasion of personal privacy,” 5 U.S.C. § 552(b)(7)(C), an agency can with
*999
hold information “if the privacy interest at stake outweighs the public’s interest in disclosure.”
Nation Magazine,
After performing the balancing analysis appropriate under Exemption 7(C), the district court found that the documents for which the Postal Service claimed the exemption — 452 of the 472 pages submitted for in camera inspection — were properly withheld from disclosure. The district court recognized the strong privacy interests of the suspects and law enforcement officers identified in the withheld documents and found that Spirko had failed to assert any “clear public interest consideration to weigh against” these interests. Spirko then offered “new evidence” of agency wrongdoing as a justification for disclosure, but the district court found that this evidence did not alter the balance, for none of the requested documents either confirmed or refuted Spirko’s “allegations of government misconduct.” Cf. id. at 1282.
Upon our de novo review of the documents submitted in camera, we agree with the district court. The vast majority of withheld pages consist of fingerprints, palm prints, photographs of former suspects, and computerized printouts of their criminal histories. The documents also include notes or phone messages concerning witnesses, suspect interviews, and discussions with law enforcement officers. None of the materials relate to the exculpatory information that Spirko claims was wrongfully withheld from him. Neither do they have any bearing on other alleged instances of misconduct by the Postal Service. All this was clearly and correctly explained in the district court’s memorandum opinion. Hence, Spirko’s challenge to the district court’s determination that the Postal Service properly withheld 452 pages under Exemption 7(C) is to no avail.
Accordingly, because the district court did not abuse its discretion in denying Spirko’s motion for further Vaughn indexing and conducting an in camera review of the documents withheld from Inspector Hartman’s desk file, and because the district court properly determined that Exemption 7(C) barred disclosure of the bulk of these documents, we affirm the judgment. 7
Notes
. On appeal, Spirko does not challenge the propriety of the redactions.
. Specifically, Inspector Hartman claimed that he had properly withheld documents from his *995 desk file under Exemptions 7(A), (C), (D), and (F). See 5 U.S.C. § 552(b)(7).
. The district court found that the Postal Service had failed to sustain its claim that many of the documents fell under Exemption 7(A), which covers "records or information compiled for law enforcement purposes” whose release "could reasonably be expected to interfere with enforcement proceedings.” 5 U.S.C. § 552(b)(7)(A). These documents, however, were fully covered by Exemption 7(C). See id. § 552(b)(7)(C).
. The form of the
Vaughn
index is unimportant and affidavits providing similar information can suffice.
See Gallant v. NLRB,
. We do not decide whether the Postal Service's submissions would have been sufficient for the district court to make a de novo determination on the claimed exemptions without in camera inspection of the documents.
. At oral argument, counsel for Spirko suggested that a more detailed Vaughn index could have indicated the number of suspects and witnesses mentioned in the withheld documents, their activities, and the precise number of pages that were comprised solely of fingerprints or palm prints. Even if such detailed information would normally have been included in the Postal Service’s Vaughn index, Spirko has not explained how such information would have helped his case or aided the district court in evaluating the agency's claimed exemptions.
. At oral argument and in a post-argument submission, Spirko contended that the district court erred by approving the Postal Service's withholding of entire documents without making specific findings as to whether each document contained segregable portions that could be released.
