Nebraska considered jailhouse informant reform

Earlier this year, Nebraska introduced legislation that would have enhanced protections against unreliable jailhouse informants, including reliability hearings, enhanced disclosure requirements, and mechanisms to keep track of the government's use of such informants.  The text of the bill (which is currently on hold) is here; story in the Lincoln Journal Star is here

The developing science of informant cognition

Behavioral psychologists have been studying the informant phenomenon, especially the thorny question of why jurors believe unreliable informants even when they know that the informants have strong incentives to fabricate evidence.  Some of those studies can be found here in the Resources & Scholarship section.

A group of researchers recently published this study finding that information from an informant can affect other witnesses in a case. Specifically, the study found that eyewitnesses who identified suspects in a line-up actually changed their identifications after learning that a jailhouse informant had implicated a different suspect.  Here is the abstract:

"Prior research has shown that primary confession evidence can alter eyewitnesses’ identifications and self-reported confidence. The present study investigated whether secondary confession evidence from a jailhouse informant could have the same effect. Participants (N = 368) watched a video of an armed robbery and made an identification decision from a photo lineup. Except for those in the no-feedback conditions, all participants then read that certain lineup members either confessed to the crime, denied involvement, or were implicated by a jailhouse informant. Jailhouse informant testimony implicating the identified lineup member led participants to have significantly higher confidence in their identification. In contrast, jailhouse informant testimony that implicated a lineup member other than the identified led participants to have significantly lower confidence in their initial identification, and 80% of these witnesses changed their identification. These results indicate that jailhouse informant testimony can influence eyewitnesses’ confidence and their identification decisions."

We already know that informant testimony can arise to bolster weak cases, providing corroboration for faulty forensic evidence or uncertain eyewitness identifications.  This new study suggests that in addition to bolstering, informant testimony can actually alter other witnesses' testimony.

The Orange County scandal has kept public attention focused on the jailhouse informant phenomenon.  This quiz published in The Marshall Project assembles some dramatic examples, and reminds us of the wide variety of benefits that informants receive, how little regulation the Supreme Court has imposed on the practice, and how easy it is for informants to collude with each other.
