A confidential informant database is a restricted law enforcement recordkeeping system that documents each source’s true identity, criminal history, reliability, handler assignments, and every payment received. These files are among the most tightly protected records in the criminal justice system. The public cannot access them through open-records requests, but portions can be pried open in court when a defendant’s right to a fair trial requires it.
What the Database Is For
The core purpose is institutional memory. Without centralized tracking, one squad might unknowingly rely on a source that another squad already flagged as unreliable or dangerous. A database makes an informant’s full history visible to authorized personnel across investigations, which helps prevent the recycling of bad sources.
These systems also enforce fiscal accountability. Every payment, expense reimbursement, and reward flows through the file with documentation of who authorized it and why. Informant programs have historically been vulnerable to corruption, with handlers pocketing funds or sources exaggerating their contributions to inflate payments. A well-maintained database is designed to catch both problems.
Who Keeps the Records
Record-keeping is tiered. Federal agencies under the Department of Justice operate interconnected national systems built to share criminal justice data across jurisdictional lines. The FBI’s Criminal Justice Information Services division manages several of these, including the National Crime Information Center for criminal records and wanted-person lookups, and the National Data Exchange, which lets investigators search incident reports, case files, and corrections data submitted by agencies nationwide.
State and local police departments run their own systems, which tend to be more limited in scope and less standardized. Many use commercial case-management software rather than purpose-built federal platforms. The practical difference is reach: federal databases support investigations spanning multiple states or involving national security, while local systems focus on regional activity. The two tiers do not automatically sync.
What Gets Logged in a CI File
Informant files are dense. The Attorney General’s Guidelines set minimum documentation requirements, and the material sorts into three categories.
Biographical Information
Before an informant can be officially registered, agents must document basic identifying information establishing the person’s true identity, any criminal history, whether the person is a current or former subject of an investigation, and whether they have ever worked as an informant for another agency.1Department of Justice. The Attorney General’s Guidelines Regarding the Use of FBI Confidential Human Sources A photograph is collected when possible. The file also records the person’s motivation for informing, including any consideration they are seeking from the government.
Operational Records
The operational side tracks handler assignments, the types of criminal activity the source reports on, and a log of every interaction and assignment. A significant component is the reliability assessment. During both the initial suitability review and every annual review afterward, agents must evaluate the person’s “reliability and truthfulness” and their track record as a witness in any proceeding.2Council of the Inspectors General on Integrity and Efficiency. The Attorney General’s Guidelines Regarding the Use of Confidential Informants Agents walk through a detailed list of factors, including the informant’s prior service record with other agencies and any history of being terminated for cause.
Financial Records
Every monetary exchange gets documented: date, amount, justification, and approver. The AG Guidelines flatly prohibit contingent payments, meaning no informant can be paid based on whether the target is ultimately convicted or punished.1Department of Justice. The Attorney General’s Guidelines Regarding the Use of FBI Confidential Human Sources The rule exists to prevent informants from fabricating evidence to secure a payday. The financial trail also helps agencies catch unauthorized activities by either the informant or the handler.
How the Files Are Supposed to Be Managed
CI databases are governed primarily by the Attorney General’s Guidelines rather than a single public statute. The guidelines are issued under the authority of 28 U.S.C. §§ 509, 510, and 533 and apply to all DOJ law enforcement agencies and federal prosecuting offices.2Council of the Inspectors General on Integrity and Efficiency. The Attorney General’s Guidelines Regarding the Use of Confidential Informants They mandate security protocols for file storage, restrict access to authorized personnel, and require detailed audit logs.
Before any source can be officially used, the handling agent must complete an Initial Suitability Report and submit it to a supervisor for validation. At least two government officials must be present when the informant receives formal instructions, which include warnings that the government will try to protect the source’s identity but cannot guarantee it, and that all information provided must be truthful.1Department of Justice. The Attorney General’s Guidelines Regarding the Use of FBI Confidential Human Sources
Each informant’s file must be reviewed at least annually, with the handling agent completing a written Continuing Suitability Report that reassesses every factor from the initial evaluation plus additional considerations like how long the source has been active and whether the same agent has been handling them throughout. For long-term informants registered more than six consecutive years, a separate review committee decides whether continued use is appropriate.2Council of the Inspectors General on Integrity and Efficiency. The Attorney General’s Guidelines Regarding the Use of Confidential Informants
Non-DOJ federal agencies follow similar frameworks. The GAO has found, however, that agencies under the Department of Homeland Security lack department-level guidance requiring their informant policies to match the AG Guidelines, creating inconsistencies in how different agencies handle the same obligations.3U.S. Government Accountability Office.

Whether the Public Can See These Records
No. Members of the public cannot obtain confidential informant records through a Freedom of Information Act request. Federal law specifically exempts law enforcement records from disclosure when releasing them “could reasonably be expected to disclose the identity of a confidential source,” including any state, local, or foreign agency that provided information on a confidential basis.4Office of the Law Revision Counsel. United States Code Title 5 Section 552 – Public Information; Agency Rules, Opinions, Orders, Records, and Proceedings That’s FOIA Exemption 7(D), and it applies broadly to any record compiled for law enforcement purposes where disclosure could expose a source.
Two other exemptions reinforce the protection. Exemption 7(A) covers records whose release could interfere with ongoing law enforcement proceedings, and Exemption 7(F) covers records whose disclosure could endanger someone’s life or physical safety.4Office of the Law Revision Counsel. United States Code Title 5 Section 552 – Public Information; Agency Rules, Opinions, Orders, Records, and Proceedings Together, these provisions make CI databases effectively immune to public records requests. Even heavily redacted versions are rarely produced because the risk of identification through contextual clues is too high.
How Defendants Get Access in a Criminal Case
The realistic path into these records runs through the courtroom, not FOIA. Three sources of law control what a defendant can pry loose.
The Informer’s Privilege and Roviaro
The government holds a recognized right to withhold the identity of people who provide information about criminal activity to law enforcement. The Supreme Court in Roviaro v. United States acknowledged this privilege but set clear limits: where disclosing an informer’s identity “is relevant and helpful to the defense of an accused, or is essential to a fair determination of a cause, the privilege must give way.”5Justia. Roviaro v. United States, 353 U.S. 53 (1957)
The Court explicitly rejected any fixed rule. Instead, judges must weigh the public interest in protecting the flow of information to the government against the individual defendant’s right to prepare a defense, considering the crime charged, possible defenses, and the likely significance of the informant’s testimony.5Justia. Roviaro v. United States, 353 U.S. 53 (1957) The strongest case for disclosure arises when the informant was the only other participant in the alleged crime, not just a tipster who pointed police in a direction. In Roviaro itself, the informant was “the sole participant, other than the accused, in the transaction charged,” which made disclosure essential.
If a court orders disclosure and the government refuses, the judge can dismiss the case entirely. That is the enforcement mechanism that prevents the government from ignoring disclosure orders with no consequence.
Brady and Giglio Material Inside the File
Even when an informant’s identity stays confidential, the prosecution has separate obligations to disclose information about the deals and benefits given to any witness who testifies. Brady v. Maryland established that suppressing evidence favorable to the accused violates due process “where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution.”6Justia. Brady v. Maryland, 373 U.S. 83 (1963) For informants, that includes anything suggesting the source lied, had a personal motive to frame the defendant, or provided unreliable information in past cases.
Giglio v. United States extended the obligation to impeachment evidence. The Court held that any “understanding or agreement as to a future prosecution” between the government and its witness is “relevant to his credibility and the jury was entitled to know of it.”7Justia. Giglio v. United States, 405 U.S. 150 (1972) A promise made by one prosecutor binds the entire office, even if the trial prosecutor didn’t personally make the deal and didn’t know about it.
This is where the database and courtroom disclosure collide. The informant’s file typically contains exactly the kind of material Giglio requires to be turned over: records of payments, promises of leniency, prior instances of unreliable information, and criminal history. When an informant takes the stand, the defense is entitled to know about those deals and that track record.
Prior Statements Under the Jencks Act
After any government witness finishes direct examination, the defense can ask the court to order the government to produce any prior statement by that witness that relates to the subject of their testimony.8Office of the Law Revision Counsel. United States Code Title 18 Section 3500 – Demands for Production of Statements and Reports of Witnesses For a testifying informant, that can include debriefing notes, written reports, and recorded statements the source gave to handlers.
If the government claims a statement contains material unrelated to the testimony, the court reviews it privately, in what’s called an in camera inspection, and removes the unrelated portions before handing the rest to the defense. Refusal to comply carries consequences. If the government won’t turn over ordered material, the court must strike the witness’s entire testimony from the record, and the judge can declare a mistrial when the testimony was central enough.8Office of the Law Revision Counsel. United States Code Title 18 Section 3500 – Demands for Production of Statements and Reports of Witnesses
How Well the System Actually Works
The rules on paper look thorough. Audits have repeatedly found serious gaps in practice. A DOJ Office of Inspector General report found that the FBI’s vetting process for confidential human sources did not comply with the AG Guidelines, and that nearly half of the FBI’s long-term informant base was awaiting validation reviews that should have already been completed.9Department of Justice Office of the Inspector General. Audit of the Federal Bureau of Investigation’s Management of Confidential Human Sources The same audit found that validation personnel were discouraged from documenting their conclusions, annual review reports were no longer being reviewed by headquarters staff, and classified informant files were not adequately safeguarded from unauthorized access.
The GAO reached similar conclusions across multiple agencies. Five of eight DOJ components had policies that did not fully address the Guidelines’ provisions for overseeing informants’ illegal activities. Some agencies failed to require written instructions to informants about authorized activities or to obtain signed acknowledgments.3U.S. Government Accountability Office. Confidential Informants: DOJ Could Better Oversee Use by Component Agencies The tracking requirements exist partly because of past mismanagement, and the problems are not fully resolved.
