Eyewitness Evidence

The Technical Working Group for Eyewitness Evidence (TWGEYEE), a multidisciplinary group of content-area experts from across the United States and Canada, was created by the National Institute of Justice (NIJ) in 1998 to develop recommended procedures for law enforcement use in investigations involving eyewitness evidence. These individuals, led by a Planning Panel com- posed of distinguished law enforcement, legal, and research professionals, authored the 1999 NIJ Research Report, Eyewitness Evidence: A Guide for Law Enforcement.
