The Role of Jailhouse Informants in Criminal Cases
Jailhouse informants, also known as “snitches,” are incarcerated people who provide testimony or information to prosecutors in exchange for lenient treatment in their own cases. The use of compensated jailhouse informant testimony in criminal trials is deeply problematic and a contributing factor in many wrongful convictions over the past several decades.
In this post, we’ll cover the following key aspects of jailhouse informants:
- What Is a Jailhouse Informant?
- Why Informants Lie
- The Risks of False Testimony
- Lack of Oversight and Transparency
- The Need for Nationwide Reform
What Is a Jailhouse Informant?
A jailhouse informant (or “snitch”) is someone who is currently incarcerated and offers to testify or provide information to police or prosecutors in exchange for benefits like reduced prison time, dropped charges, money, or other special treatment.
Informants may claim that the defendant confessed to them or revealed other incriminating details while they were imprisoned together pre-trial or after conviction. Or they might offer secondhand information about a crime gathered from other inmates.
Prosecutors may use jailhouse informant testimony to support their cases. The prospect of reduced charges, a shorter sentence, or special treatment can give an informant a reason to invent or exaggerate an account. The Innocence Project identifies unreliable jailhouse informant testimony as a recurring cause of wrongful convictions.
Why Informants Lie
Jailhouse informants lie because they are incentivized to help prosecutors in exchange for personal benefits. The prospect of securing their own freedom is a powerful motivator to falsely implicate other prisoners. Informants typically receive substantial sentence reductions, dismissed charges, cash payments, or other significant benefits for their cooperation.
In addition, the culture inside jails and prisons teaches inmates how prosecutors and police leverage informant testimony to strengthen their cases. Veteran snitches educate newcomers on gathering plausible information and fabricating believable confession stories.
Ambitious prisoners realize they can increase their value by eliciting incriminating statements from high-profile defendants or credibly testifying that the defendant admitted guilt. The implicit understanding is that such enterprising efforts will pay off down the road in the form of greater leniency benefits.
The Risks of False Testimony
The Innocence Project reports that 17% of the first 375 DNA exonerations in the United States involved informants. That figure covers cases from 1989 through 2020 and refers to informants generally, rather than only jailhouse informants.
In many of these tragic cases, prosecutors withheld crucial facts from defense attorneys regarding the incentives provided to the informant witnesses. Some district attorney offices even deliberately avoided tracking benefits or other impeachment evidence that could undermine their informant’s credibility on cross-examination.
Judges and juries could not accurately assess their truthfulness without fully disclosing the informants’ backgrounds and their compensation in exchange for their testimony. Yet claims of jailhouse confessions can be compellingly believable even when completely fabricated.
Lack of Oversight and Transparency
Existing legal protections do not eliminate the risk of false informant testimony. Under Brady and Giglio, prosecutors must disclose material evidence favorable to the defense, including evidence that could undermine a prosecution witness’s credibility. Promises of leniency or other benefits can bear directly on whether a jury should believe an informant.
In Florida, when the defense elects to participate in discovery, Florida Rule of Criminal Procedure 3.220(b)(1)(M) requires specific disclosures about informant witnesses. These include the defendant’s alleged statement, when and where it was made, the informant’s criminal history, any benefit received or expected for testimony, and prior cooperation for benefits known to the prosecutor. These disclosures help the defense test the informant’s account and expose possible motives to lie.
Through discovery in Florida criminal cases, defense counsel can seek the informant’s prior statements and records of promised benefits, compare the account with other evidence, and prepare questions that expose inconsistencies or bias.
This lack of national standards around procuring and presenting informant testimony means shocking numbers of factually innocent people have lost years of their lives based solely on unsupported and incentivized claims from known criminals.
True accountability for the government’s prolific use of compensated informant witnesses is the only way to curb the trend of convictions predicated on self-serving fiction.
The Need for Nationwide Reform
The Innocence Project and other justice reform groups have long called for commonsense nationwide regulations, including:
- Pretrial “reliability” hearings to weigh the credibility of jailhouse informants
- Robust tracking systems detailing benefits conferred upon informants
- Full disclosure to defendants regarding informant incentives and background
- Clear jury instructions explaining the inherent unreliability of jailhouse witnesses
- Expert testimony on typical informant practices and jail culture
Reform should build on existing disclosure duties through better tracking of informants, closer scrutiny of their accounts, and enforcement when prosecutors fail to disclose required information.
The human cost of this lack of accountability is unacceptable. Until binding standards govern informant recruitment and testimony in every jurisdiction, innocent people will continue having their lives ruined based on nothing more than lies from incentivized snitches.
Courts and juries need enough information to assess an informant’s credibility. A related issue is when the defense can require disclosure of a confidential informant’s identity in Florida. To learn more about efforts to prevent wrongful convictions, visit the Innocence Project.
