Criminal informants are famously unreliable. Jailhouse snitch testimony often leads to wrongful conviction. Over 45 percent of all innocent people exonerated from death sentences were wrongfully convicted based on the testimony of a lying criminal informant. This makes snitches the leading cause of wrongful conviction in U.S. capital cases.
Police sometimes use children as young as 14 as informants. These children may be exposed to drugs, violence, and other criminal activities as they work to get information for their handlers. Some have been killed. California and New Jersey have laws restricting the practice: in other states police have discretion to use juvenile informants.
Some informants are serious criminals who receive leniency for their own crimes. The FBI has been known to use murderers as informants. Many jurisdictions permit drug dealers to continue selling drugs in exchange for cooperation. In 2011, the crimes committed by FBI informants alone totaled over 5,600.
Informants are a staple of drug enforcement. This means that where drug enforcement is heaviest, informant activity is also heaviest. Because drug arrests occur disproportionately in low-income African American neighborhoods, those residents must live with the crime, violence, and distrust that go with criminal informant use.
Many states are rethinking their criminal informant policies. Some have passed laws restricting the use of jailhouse snitch witnesses. Some have created new rules for disclosure and accountability. The U.S. Congress is considering a number of reforms that would improve transparency and safety. In the future, the laws governing criminal informants will likely look very different than they do today.
