To learn what agencies across the United States are doing about eyewitness identification, the National Institute of Justice (NIJ) awarded the Police Executive Research Forum (PERF) a grant to develop and conduct a nationally representative survey. The survey collected statistical data and descriptive information on current policies, practices, and training protocols related to the eyewitness identification process. The purpose was to describe the state of the field with respect to eyewitness identification procedures and to assess agency progress and change since the 1999 publication of NIJ’s Eyewitness Evidence: A Guide for Law Enforcement (Eyewitness Evidence Guide).
