Some of the most significant disclosures of informant-related information have come through sustained FOIA litigation. The Ernest Withers case is instructive: a newspaper's two-year legal battle, costing hundreds of thousands of dollars, eventually forced the FBI to release documents and photos from Withers' informant file. The FBI also reimbursed the newspaper for $186,000 in legal fees.
A confidential informant (CI) is an individual who provides information to law enforcement agencies on a confidential basis, often in exchange for protection, immunity, or financial compensation. CIs can be anyone, from a concerned citizen to a suspect looking to reduce their sentence or someone with a personal vendetta against a particular individual or organization.
Beyond the immediate violence, the publication of a CI list would destroy the future of policing. Confidentiality is the currency of cooperation. A potential informant must believe that their name will never see sunlight. They must trust that the handler, the prosecutor, and the court system can keep a secret even under the pressure of cross-examination. confidential informant list for my city exclusive
Confidential Informant List For My City: Understanding the Risks and Realities of Informant Exposure
Beyond FOIA, American courts have long recognized the common law "informer's privilege"—the government's right to withhold the identity of persons who furnish information about violations of law. This privilege is designed to encourage citizens to come forward with information about criminal activity without fear of retaliation. The privilege is not absolute, however. Courts have carved out exceptions, most notably when the informer appears as a witness for the government or when disclosure is essential to a fair determination of a defendant's guilt or innocence. A confidential informant (CI) is an individual who

In the end, the demand for a confidential informant list for my city exclusive fails the most basic ethical test: the minimization of harm. A name on a list is not a data point; it is a human being. It is a mother who called the tip line about a gun in her son’s school. It is a low-level dealer who gave up a kingpin to avoid a ten-year mandatory minimum. It is a survivor of domestic violence who identified her abuser’s illegal arsenal.
In short: There is no publicly accessible, official "exclusive list" of confidential informants for any city.
The problem extends far beyond Massachusetts. In California, the Orange County Sheriff's Department and District Attorney's Office operated an extensive jailhouse informant program for years that was later condemned as unconstitutional. The Department of Justice opened an investigation into informant practices spanning from 2007 to 2016, ultimately securing settlement agreements requiring reforms in January 2025. The litigation revealed that jailhouse informants had been illegally used to elicit statements from defendants, undermining the constitutional right to counsel.
"This 'City Exclusive' report provides an eye-opening and rare glimpse into the local law enforcement’s use of confidential human sources. By compiling data on payments and reliability, this project pulls back the curtain on how 'snitch' culture operates in our specific neighborhoods. The level of detail—from the types of crimes targeted to the costs incurred by taxpayers—is impressive. While it doesn't (and legally shouldn't) name individuals to prevent retaliation, it serves as a critical accountability tool for assessing whether these programs are managed with proper oversight." 3.
