             INFORMANT WITNESSES AND THE RISK OF
                       WRONGFUL CONVICTIONS


Jessica A. Roth*
                                    ABSTRACT

   Several studies in the last two decades have revealed that false criminal
informant testimony is a leading factor in wrongful convictions, along with false
confessions, eyewitness misidentification, and faulty forensic science. Although a
great deal more remains to be done, many jurisdictions have implemented
evidence-based reforms to these last three categories of evidence. Policy about
criminal informants, however, seems to be stubbornly stagnant, and relevant social
science is virtually nonexistent. This Article questions the relative lack of attention
to informant testimony and suggests that the dangers posed by informant testimony
are both greater and different than previously thought. Unlike much of the prior
literature on the subject, this Article carefully distinguishes between jailhouse
informants and other types of informant witnesses, especially accomplices. Al-
though both categories of informants pose some of the same risks to the reliability
of proceedings, accomplice witnesses pose additional risks-many enabled by
rules of evidence, trial practices, and psychological phenomena-that have not yet
been fully appreciated in the literature. After identifying these concerns, this
Article concludes with recommendations for reform--and areas requiring further
study-with the aim of developing a set of evidence-based best practices for the
use of informant testimony.

   Since 1989, DNA evidence has been used to exonerate at least 341 individuals,
in at least thirty-seven states, of crimes of which they were previously convicted.'
In many of these cases, the exonerees served decades in prison or were sentenced
to death before they were released.2 These DNA exonerations have changed the
face of criminal justice in the United States.3 No longer is the prospect of an
