Scientific Procedures for Eyewitness Evidence for U.S. Law Officers

Abstract

To significantly reduce eyewitness error, law officers must do the following: (a) identify the relevant eyewitness factors at the crime scene and determine how they likely affected eyewitness accuracy; (b) apply scientific procedures to eyewitness interviews; and (c) use scientific procedures for identification procedures. Research shows, however, that most U.S. law officers have limited knowledge of eyewitness factors and fail to follow proper procedures for eyewitness interviews and identification procedures. By following the recommended procedures delineated in this article, law officers will be able to substantially reduce wrongful convictions from eyewitness error and significantly strengthen the state's evidence in criminal cases.
