WILKINSON, Circuit Judge:

The Freedom of Information Act grants members of the public broad access to 

federal agency records upon request. 5 U.S.C. § 552(a). But that access is not unlimited. 

An agency may withhold records if it can establish that they fall within one of the Act’s 

exemptions. This case primarily involves exemption 7(A), which permits an agency to 

withhold certain law enforcement records whose release “could reasonably be expected to 

interfere with enforcement proceedings.” 5 U.S.C. § 552(b)(7)(A). The FBI invoked this 

exemption to withhold records requested by appellant Mark Zaid related to the criminal 

investigation into one of his clients. Zaid sued the FBI to release the requested records, but 

the district court found that the records were exempt from disclosure. For the reasons that 

follow, we affirm the district court’s judgment. 

I.

A.

In March 2020, the United States charged Zackary Sanders with production and 

possession of child pornography in the U.S. District Court for the Eastern District of 

Virginia. See United States v. Sanders, No. 1:20-cr-143-TSE (E.D. Va. 2020). The 

prosecution arose after an undisclosed foreign law enforcement agency informed the 

Federal Bureau of Investigation (FBI) that an IP address registered to Sanders’s residence 

had been used to access violent child pornography on the web. 

B.

In April 2021, attorney Mark Zaid submitted a Freedom of Information Act (FOIA) 

request to the FBI for fourteen types of records related to the Sanders investigation. Request

numbers (1)–(10) and (13) are at issue in this appeal and involved the following 

information: (1) information received by the FBI from a foreign law enforcement agency 

on or about August 19, 2019; (2) copies of the warrants received from said law enforcement 

agency; (3) an administrative subpoena relating to the target IP address; (4) the report 

drafted by the FBI Special Agent assigned to the case to open an investigation into the 

target IP address; (5) the February 2020 search warrant stating that a user of the target IP 

address accessed child pornography; (6) any records outlining information relied upon in 

forming the basis for the February 10 warrant; (7) any communication between the U.S. 

government and the foreign law enforcement agency regarding the target IP address or 

website used to access the pornography; (8) any records outlining the government’s 

deanonymizing the IP addresses used to access the pornography; (9) any FBI affidavits, 

sworn declarations, court filings or internal records that contain any of nine search terms; 

(10) affidavits or sworn declarations filed in federal district court by the Special Agent 

assigned to the case since May 2016; and (13) any records identifying the foreign law

enforcement agency that tipped the FBI off to Sanders’s malfeasance. See J.A. 95–97.

The FBI ran the requested searches and advised Zaid that the records he requested 

were located in an investigative file exempt from disclosure under FOIA exemption 7(A) 

because they were “compiled for law enforcement purposes” and their release “could 

reasonably be expected to interfere with enforcement proceedings.” J.A. 21; see 5 U.S.C. 

§ 552(b)(7)(A). Zaid challenged the FBI’s withholding of the above records in the U.S. 

District Court for the District of Maryland. See Zaid v. DOJ, 2023 WL 4351401, at *1 & 

n.2 (D. Md. July 5, 2023). 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 3 of 18

As the FOIA dispute evolved in Maryland, the criminal case against Sanders 

advanced in Virginia, culminating in Sanders’s conviction of several counts of production, 

receipt, and possession of child pornography in October 2021. See United States v. Sanders,

No. 1:20-cr-143-TSE (E.D. Va. 2020). 

After Sanders’s conviction, the FBI renewed its search for records responsive to 

Zaid’s FOIA request. Between October 2021 and September 2022, the FBI sent Zaid 

several letters informing him of its progress and releasing certain nonexempt documents. 

The FBI maintained, however, that records in Sanders’s investigative file were 

categorically exempt under 7(A). 

C.

Upon completing its search for responsive records, the government moved for 

summary judgment on Zaid’s FOIA challenge. The government principally argued that the 

records it withheld were categorically exempt from disclosure under exemption 7(A). It 

argued that the records were also exempt under other FOIA exemptions, in the alternative. 

In support of its motion, the government attached a declaration from Michael Seidel, 

Chief of the Record/Information Dissemination Section within the FBI’s Information 

Management Division. Seidel attested that after Sanders’s conviction, the FBI reached out 

to the Special Agent assigned to the case “to determine whether the release of information 

within the responsive file would still cause harm to any pending enforcement proceeding.” 

J.A. 40. According to the declaration, the Special Agent stated that release of the responsive 

records would still reasonably be expected to interfere with ongoing proceedings in 

Sanders’s own criminal case, including his pending appeal and future collateral challenges. 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 4 of 18
5

The Seidel declaration did not stop there. It noted that in addition to proceedings

against Sanders himself, the Special Agent “advised that the responsive records are part of 

ongoing investigations of third-party individuals” and that “release of the information 

could interfere with those pending investigations even after Sanders’s appeals . . . are 

exhausted.” J.A. 40–41, 45. The declaration explained that “release of these records would 

allow these third-party individuals to critically analyze documents concerning these 

investigations,” giving them “the unique advantage of prematurely knowing the details 

surrounding the investigation of their criminal activities, including the identity of victims 

and direct and circumstantial evidence gathered during the investigation.” J.A. 45. This, 

the declaration explained, posed the risk that the targets “could use the released information 

to their advantage to alter or destroy evidence, create false evidence, harass or otherwise 

intimidate victims and . . . witnesses, or evade the FBI’s investigative efforts.” J.A. 45. 

After establishing that the records continued to pose a threat to enforcement 

proceedings, the Seidel declaration stated that providing a document-by-document 

description of the responsive records within Sanders’s investigative file would undermine 

the very interests that the FBI sought to protect in withholding them. Instead, the 

declaration broke the records down into nineteen “types of records”—including

“Electronic Communications,” “Non-Public Court Documents,” and “Memoranda and 

Correspondence”—and provided detailed descriptions for each. See J.A. 42–44. 

The declaration then “grouped the responsive records into functional categories” to 

demonstrate how the information contained therein could reasonably be expected to 

interfere with enforcement proceedings. J.A. 45–46. The declaration set forth two 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 5 of 18
6

functional categories of records, and then broke those categories down further into 

functional subcategories. It explained that “[e]ach responsive record withheld falls into 

either one or both of the functional categories.” J.A. 46. The first category, “Administrative 

Material,” is not at issue in this appeal. J.A. 46–47.

The second category, “Evidentiary and Investigative Material,” “includes evidence, 

analyses of evidence, and derivative communications discussing or incorporating 

evidence.” J.A. 47. The two subcategories of “Evidentiary and Investigative Material,” are 

(1) “Information Concerning Physical and Documentary Evidence” and (2) “Records 

Containing the Exchange of Information between Law Enforcement Agencies.” J.A. 47–

48.

The declaration provided detailed descriptions of each functional subcategory and 

“the anticipated harm that could reasonably result from the release of this material.” J.A. 

46–48. Beginning with Information Concerning Physical and Documentary Evidence, the 

declaration described the subcategory as follows:

Information concerning physical and documentary evidence may include 

information or summaries of information obtained from searches and 

seizures, surveillance, victim interviews, subpoenas, laboratory reports, and 

other law enforcement activities. To more fully describe this information 

could reasonably lead to disclosure of non-public aspects of pending 

investigative efforts. 

J.A. 47–48. 

The Seidel declaration then explained how release of the information within that 

subcategory “could be detrimental to the success of pending and prospective enforcement 

proceedings” by (1) “permitting subjects to estimate the scope of the FBI’s investigation 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 6 of 18
7

and judge whether their activities are likely to be detected”; (2) “allowing investigative 

subjects to discern the FBI’s investigative strategies and employ countermeasures to avoid 

detection and disruption by law enforcement”; and (3) “allow[ing] investigative targets to 

formulate strategies to contradict evidence to be presented in court proceedings.” J.A. 48.

The declaration described the second subcategory, Records Containing the 

Exchange of Information between Law Enforcement Agencies, as containing “records 

documenting and detailing the exchange of information among the FBI and its law 

enforcement partners . . . to help identify subjects and individuals of investigative interest 

and to assist in locating witnesses and victims.” J.A. 48. It cautioned that this cooperative 

effort was based on “the mutual understanding that information provided to the FBI by 

these agencies [would] not be prematurely released.” J.A. 48.

The declaration then linked the disclosure of such information to the potential 

repercussions of its release. It stated that release of the records in this subcategory “would 

identify the FBI’s investigative interest in particular individuals and subject third parties, 

such as witnesses and victims, to potential harassment or other forms of intimidation, and 

physical and mental harm.” J.A. 48.

After completing its discussion of exemption 7(A), the declaration set forth the 

government’s alternative argument that the withheld records were also exempt from 

disclosure under the other FOIA exemptions.

D.

Zaid challenged the government’s motion for summary judgment on the basis that 

the government had not met its evidentiary burden to establish that all of the records 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 7 of 18
8

withheld were exempt under exemption 7(A) or the alternative exemptions. He cited a 

recent Middle District of Florida decision in related litigation rejecting the government’s 

invocation of the same exemptions. See Smith v. DOJ (“Smith I”), 2022 WL 4110291 (M.D. 

Fla. Sept. 8, 2022). That case involved an identical FOIA request submitted by Zaid’s law 

firm challenging the three types of information not at issue in this appeal: (11) records 

relating in any way to Zackary Sanders from May 2019 to February 2020; (12) records 

pertaining to Sanders’s IP address from May 2019 to February 2020; and (14) records 

referencing the terms “Hurtcore” and “FLA.” Id. at *1.

Relying on the Middle District of Florida’s reasoning, Zaid argued that the FBI’s 

declarations invoking the exemptions did not provide the necessary level of specificity with 

respect to the two functional subcategories of Evidentiary and Investigative Material

discussed above: (1) Information Concerning Physical and Documentary Evidence and 

(2) Records Containing the Exchange of Information Between Law Enforcement 

Agencies. 

E.

The government submitted two additional declarations in reply to Zaid’s opposition 

to its motion for summary judgment: a second declaration from Seidel and one from an 

FBI Special Agent assigned to investigate child pornography cases. See J.A. 245–58, 260–

263. Zaid did not object to these additional declarations. 

The FBI Special Agent largely expounded upon the information contained in the 

first Seidel declaration. But the second Seidel declaration elaborated on the repercussions 

of requiring the FBI to disclose records in the Records Containing the Exchange of 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 8 of 18
9

Information between Law Enforcement Agencies subcategory. It stated that the 

“cooperative exchange of information between the FBI and other law enforcement agencies 

is based on the mutual understanding”—and sometimes, written agreement—that 

“information provided to the FBI by these agencies will not be prematurely released and 

the identity of the law enforcement agencies providing such information will not be 

disclosed.” J.A. 250. It cautioned that, if the FBI does not follow through on its end of the 

bargain, its partners may be “hesitant to share information, which would, in turn, diminish 

the scope or volume of reliable intelligence or investigative information available to the

FBI, causing harm to FBI investigations.” J.A. 251.

F.

Before the district court ruled on the motion, Zaid filed a notice of supplemental 

information alerting the district court to a second opinion from the Middle District of 

Florida rejecting the government’s renewed motion for summary judgment. See Smith v. 

DOJ (“Smith II”), 2023 WL 4350537 (M.D. Fla. May 10, 2023). In that case, the 

government had included additional declarations to support its renewed motion, but the 

Middle District of Florida found that the declarations were still insufficient to invoke the 

claimed exemptions. Id. at *3. Zaid argued that the district court in the present case should 

find the same.

G.

The district court granted the government’s motion for summary judgment. See

Zaid, 2023 WL 4351401, at *11–12, 18. The court held that, “contrary to [Zaid’s] 

unsupported lamentations,” the government’s submissions were sufficient to show that it 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 9 of 18
10

had “properly invoked the categorical exemption of 7(A).” Id. at *12. It found that, in the 

alternative, the other exemptions were sufficient to warrant summary judgment on Zaid’s 

FOIA challenge as well. Id. at *13–17.

Zaid filed a timely appeal. 

II.

“The question of whether a district court properly granted the government summary 

judgment in a FOIA action is one of law which we review de novo.” Hanson v. U.S. Agency 

for Int’l Dev., 372 F.3d 286, 290 (4th Cir. 2004). Because the government bears the burden 

of proving requested materials are exempt from disclosure, we must ensure the government 

provided the district court with “an adequate factual basis for the decision rendered.” Rein 

v. U.S. Pat. & Trademark Off., 553 F.3d 353, 358 (4th Cir. 2009); Spannaus v. DOJ, 813 

F.2d 1285, 1288 n.4 (4th Cir. 1987). This is no different than in any other case where a 

party moves for summary judgment on an issue for which it will bear the burden of 

persuasion at trial. See, e.g., Hunt v. Cromartie, 526 U.S. 541, 553 (1999) (discussing 

entitlement to summary judgment where movant bears the “burden of persuasion”). 

III.

A.

“The basic purpose of FOIA is to ensure an informed citizenry, vital to the 

functioning of a democratic society, needed to check against corruption and to hold the 

governors accountable to the governed.” NLRB v. Robbins Tire & Rubber Co., 437 U.S. 

214, 242 (1978). Thus FOIA provides that “when ‘any person’ makes a sufficiently specific 

and reasonable request for records from a government agency, the agency ‘shall make the 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 10 of 18
11 

records promptly available.’” Am. Mgmt. Servs., LLC v. Dep’t of the Army, 703 F.3d 724, 

728 (4th Cir. 2013) (quoting 5 U.S.C. § 552(a)(3)(A)). As the government grows in size 

and complexity, the need for agency transparency becomes more apparent. 

But Congress recognized that “public disclosure is not always in the public interest,” 

Baldrige v. Shapiro, 455 U.S. 345, 352 (1982). The FOIA statute therefore contains nine 

exemptions that “reflect a wide array of concerns,” Hunton & Williams v. DOJ, 590 F.3d 

272, 277 (4th Cir. 2010), and “are designed to safeguard various public interests against 

the harms that would arise from overbroad disclosure,” Hanson, 372 F.3d at 290. 

This appeal primarily concerns exemption 7(A), which permits the withholding of 

“records or information compiled for law enforcement purposes” whose disclosure “could 

reasonably be expected to interfere with enforcement proceedings.” 5 U.S.C. 

§ 552(b)(7)(A). Zaid challenges the district court’s determination that the FBI was entitled 

to withhold documents based on exemption 7(A) or other exemptions in the alternative. 

Because we find that exemption 7(A) protects the disputed records from disclosure, we 

need not reach the other exemptions. 

B. 

Investigations by their very nature may require a measure of nondisclosure as law 

enforcement gathers evidence before an arrest may lawfully be made and a prosecution 

fairly brought. Congress enacted exemption 7(A) because it “recognized that law 

enforcement agencies had legitimate needs to keep certain records confidential, lest the 

agencies be hindered in their investigations or placed at a disadvantage when it came time 

to present their case.” Robbins Tire, 437 U.S. at 224. “Foremost among the purposes of 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 11 of 18
12

this Exemption was to prevent ‘harm [to] the Government’s case in court,’ by not allowing 

litigants ‘earlier or greater access’ to agency investigatory files than they would otherwise 

have.” Id. at 224–25 (citation omitted).

Although we generally construe FOIA exemptions narrowly, J.P. Stevens & Co. v. 

Perry, 710 F.2d 136, 139 (4th Cir. 1983), the text of § 552(b)(7)(A) is broadly worded. 

Indeed, Congress amended the statute in 1986 to expand the scope of exempt law 

enforcement records from those which “would” interfere with enforcement proceedings to 

those which “could reasonably be expected” to do so. See Pub. L. 99–570, 100 Stat 3207 

(October 27, 1986). Thus, the government’s showing “is to be measured by a standard of 

reasonableness, which takes into account the lack of certainty in attempting to predict harm 

while providing an objective test.” Spannaus, 813 F.2d at 1288 (internal quotation marks 

omitted).

The agency bears the burden to establish that exemption 7(A) applies. 5 U.S.C. 

§ 552(a)(4)(B). But it need not establish that 7(A) applies to each record withheld. The 

Supreme Court has held that the exemption may be invoked on a categorical or “generic” 

basis by grouping records into categories and explaining how each category would 

generally interfere with enforcement proceedings. See Robbins Tire, 437 U.S. at 223–24. 

In Spannaus, we held that the government “fully met its burden” to invoke 

exemption 7(A) when it “categorized the kinds of documents at issue and . . . specifically 

identified the type of information they contain and the harms their release could have in 

pending proceedings.” 813 F.2d at 1289. There the FBI stated that a Vaughn index of the 

responsive records would “jeopardize enforcement proceedings and defeat the purpose of 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 12 of 18
13

the exemption.” Id. at 1287. So it submitted a declaration in support of its motion for 

summary judgment that described categories of the records at a general level and explained 

how their disclosure would interfere with enforcement proceedings. Id.

The declaration stated that the requested records included details about the decision 

to open and to pursue the investigation; witness interviews; prosecutors’ opinions; and 

“other sundry items of information.” Id. It then identified three ways in which such 

information’s release could interfere with enforcement proceedings: “(1) destruction or 

alteration of evidence yet to be discovered; (2) identification of individuals who possess 

information relative to the investigation, leading to possible intimidation and/or harm; and, 

(3) use of the information released to establish fraudulent alibis.” Id. On this record, we 

found that the government had “fairly describe[d] the content of the material withheld and 

adequately state[d] its grounds for nondisclosure,” and affirmed summary judgment in its 

favor. Id. at 1289 (quoting Barney v. IRS, 618 F.2d 1268, 1272 (8th Cir. 1980)).

The government’s evidence in the present case falls safely within the scope of 

protection established in Spannaus. In both cases, the government conducted a documentby-document review of the records, grouped them into functional categories, and 

demonstrated how release of information contained within those functional categories 

could reasonably be expected to interfere with enforcement proceedings. Here the 

government submitted almost one hundred pages of declarations that “explained in detail 

why [exemption 7(A)] applied to the information and documents withheld.” See Bowers v. 

DOJ, 930 F.2d 350, 353 (4th Cir. 1991). “This is substantially more than is required” and 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 13 of 18
14

provided the district court with an adequate basis for finding the government had met its 

burden. Id. at 357 (discussing Spannaus, 813 F.2d at 1288). 

C. 

Zaid does not dispute that it was the government’s prerogative to invoke exemption 

7(A) on a categorical basis. Instead, he argues that the government failed to sufficiently 

describe the two functional subcategories at issue. His arguments are without merit. 

Regarding the Information Concerning Physical and Documentary Evidence 

subcategory, Zaid contends that the FBI failed to describe the records in a functional 

manner because the declaration only described what the subcategory “may” include. But, 

as in Spannaus, the government here asserted that providing a more detailed description 

“could reasonably lead to disclosure of non-public aspects of pending investigative 

efforts.” Compare J.A. 48 with Spannaus, 813 F.2d at 1287. Zaid has not endeavored to 

dispute this risk, nor has he questioned the government’s good faith in making the 

assertion. See Am. Mgmt. Servs., LLC, 703 F.3d at 733 (“Because we have ‘no reason to 

question the good faith of the [agency],’ we are ‘entitled to accept the credibility of the 

affidavits.’”).

Moreover, the link between releasing information “obtained from searches and 

seizures, surveillance, victim interviews, subpoenas, laboratory reports, and other law 

enforcement activities” and the risk to other “pending and prospective” child pornography 

proceedings is clear. J.A. 47–48. Such information would naturally and necessarily allow 

other defendants in Sanders’s criminal circle to “discern the FBI’s investigative strategies 

and employ countermeasures to avoid detection and disruption by law enforcement; and 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 14 of 18
15

allow investigative targets to formulate strategies to contradict evidence to be presented in 

court proceedings.” J.A. 48. We find that the government’s prediction of harm was 

“reasonable[]” and warranted exemption 7(A) protection. See Spannaus, 813 F.2d at 1288.

Zaid also claims that the FBI failed to define the Exchange of Information Between 

Various Law Enforcement Agencies subcategory functionally because it only linked the 

records to past investigative efforts. See Robbins Tire, 437 U.S. at 230 (“[T]he Exemption 

d[oes] not endlessly protect material simply because it was in an investigatory file.”). 

Not so. The Seidel declaration rationally linked the disclosure of records 

documenting the exchange of information between the FBI and its law enforcement 

partners to an interference with prospective enforcement proceedings. Namely, that 

“release of this information would identify the FBI’s investigative interest in particular 

individuals and subject third parties, such as witnesses and victims, to potential harassment 

or other forms of intimidation, and physical and mental harm.” J.A. 48. We have held that

these kinds of harm “warrant an exemption under subsection (b)(7)(A).” Spannaus, 813 

F.2d at 1289. 

Zaid contends that these risks were insufficiently concrete because the government 

failed to point to any specific prospective law enforcement proceeding, instead relying on 

“abstract prospective possibilities.” Appellant’s Reply Br. at 4. But this ignores the covert, 

online nature of child pornography offenses. 

The name of the game in child pornography prosecutions is compiling evidence of 

a target’s receipt or possession of child pornography. See, e.g., United States v. Miltier, 

882 F.3d 81, 86–87 (4th Cir. 2018). Such materials are generally accessed online and 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 15 of 18
16

downloaded to a personal computer. Id. at 85–86. A prospective target that knows he is 

being monitored by the FBI could try to alter or conceal evidence of past use and could 

inform other users of the websites he frequented to do the same. In other words, the 

government cannot point to a prospective target without undermining its case against him

and potentially others in his criminal network. 

Moreover, the government noted the general risk to future enforcement proceedings 

if the FBI were forced to disclose its communications with other law enforcement agencies. 

See J.A. 48. We have recognized that disclosure of records that would “reveal information 

provided to the FBI by a foreign government” and “identify the governmental entity in 

question . . . would have a chilling effect on the free flow of information between the 

United States intelligence and law enforcement agencies and their foreign counterparts.” 

Bowers, 930 F.2d 357–58. The second Seidel declaration represented that this would, “in 

turn, diminish the scope or volume of reliable intelligence or investigative information 

available to the FBI, causing harm to FBI investigations.” J.A. 251. We cannot ignore the 

commonsense conclusion that requiring disclosure of these documents would make other 

law enforcement agencies, foreign or domestic, think twice before assisting the FBI. 

Zaid primarily relied on two Middle District of Florida decisions to argue that the 

government had not met its burden. Smith I, 2022 WL 4110291; Smith II, 2023 WL 

4350537. Although those cases involved different parts of the FOIA request, the issues 

presented there were essentially the same as those presented in this case. But Zaid 

acknowledges that those cases were not binding on the district court here. Appellant’s 

Opening Br. at 26 (citing Camreta v. Greene, 563 U.S. 692, 709 n.7 (2011)). And they are 

USCA4 Appeal: 23-1821 Doc: 32 Filed: 03/25/2024 Pg: 16 of 18
17

certainly not binding on this court. See Cooper v. Harris, 581 U.S. 285, 298–99 (2017)

(“Whatever findings are under review receive the benefit of deference, without regard to 

whether a court in a separate suit has seen the matter differently.”). Our review of the record 

convinces us that the district court had a more-than-adequate basis for finding exemption 

7(A) applied.

IV.

Far from invoking a “blanket exemption” for all records in Sanders’s investigative 

file, Crooker v. Bureau of Alcohol, Tobacco and Firearms, 789 F.2d 64, 65 (D.C. Cir.

1986), the government here broke down the kinds of records withheld under exemption 

7(A) into nineteen well-defined categories, it conducted a document-by-document review 

of the records, it grouped them into functional categories, and it demonstrated how release 

of information contained within those functional categories could reasonably be expected 

to interfere with enforcement proceedings, not only against Sanders, but other prospective 

child pornography targets as well. 

If the government’s declarations here do not establish its entitlement to exemption 

7(A), it is hard to imagine declarations that could meet this burden without requiring the 

government to reveal the very information it sought to protect. Indeed, to hold against the 

government in this case would set the burden so high as to risk writing the exemption out 

of the statute. 

The purpose of FOIA is “to pierce the veil of administrative secrecy and to open 

agency action to the light of public scrutiny,” Dep’t of Air Force v. Rose, 425 U.S. 352, 

361 (1976), not to give criminal suspects “earlier or greater access to agency investigatory

files than they would otherwise have,” Robbins Tire, 437 U.S. at 224 (internal quotation 

marks omitted). The Federal Rules of Criminal Procedure for example make clear what 

government records are available to defendants and when. See Fed. R. Crim. P. 16.

Congress enacted exemption 7(A) in part to prevent litigants from using FOIA to

supplement or override the Federal Rules. John Doe Agency v. John Doe Corp., 493 U.S. 

146, 153 (1989) (“In deciding whether Exemption 7 applies, moreover, a court must be 

mindful of this Court’s observations that the FOIA was not intended to supplement or 

displace rules of discovery.”). We serve that purpose by upholding the district court’s grant 

of summary judgment on Zaid’s FOIA challenge. 

The judgment of the district court is hereby affirmed. 

AFFIRMED
