2002, he provided training to Canadian judges on the issues with eyewitness identification. The training was developed by the National Judicial Institute and by the end of 2004, he had trained about 65% of the criminal court justices in Canada. Lindsay is a member of the Technical Working Group for Eyewitness Evidence and participated in the development and the writing of the American national guidelines for obtaining and preserving eyewitness evidence. He continues to work on developing training materials to accompany the Eyewitness Evidence: A Guide for Law Enforcement. Lindsay has also consulted in one of the United Nations war crime trails for Rwanda over genocide. He was asked by the United Nations prosecutors to consult with them when the defense called an expert witness to testify. During June and July 1998 he read e-mailed transcripts of the witness's testimony and provided the prosecutors comments and suggested questions for their cross-examination. In September 1998 he was called to testify in Arusha, Tanzania. Publications He has also had a lot of his work published throughout the years. Two of his books were published in 2007: Handbook of Eyewitness Psychology: Memory for People and Handbook of Eyewitness Psychology: Memory for Events. Most of his published work has been articles in referred journals. Some examples of his articles in referred journals are Eyewitness Accuracy Rates in Police Showup and Lineup Presentations: A Meta-Analytic Comparison, Eyewitness Accuracy Rates in Sequential and Simultaneous Lineup Presentations: A Meta-Analytic Comparison, Identification Accuracy of Children Versus Adults: A Meta-Analysis, and Cross-Race Facial Recognition: Failure of the Contact Hypothesis. These are just a few examples of the many articles of his that are referred to in different journals. Research Interests and Areas of Study Factors that Influence Eyewitness Accuracy Lindsay has expressed interest in many areas of research dealing with eyewitness memory and has done a great deal of research in several areas to determine factors that influence eyewitness accuracy and to what extent. Early on, Lindsay used a meta-analytic comparison to study accuracy differences between simultaneous lineup presentations and sequential lineup presentations. As the results from this study showed, the type of lineup presentation that is used affects the accuracy of eyewitness memory. The results showed that accurate identification from target-present lineups occurs much higher in a simultaneous lineup than sequential lineups. However, correct rejection rates were much higher for sequential than simultaneous lineups. Recently, Lindsay has researched
