Policing and Wrongful Convictions

Harvard Kennedy SchoolSince 1989, there have been more than 1,300 exonerations in the United States—more than 300 of which occurred through newly discovered DNA evidence. This report by the Harvard Kennedy School reviews what has been learned from studying exonerations in the past 20 years, including factors such as cognitive biases that contribute to wrongful convictions. It also provides information on evidence-based police practices related to eyewitness identification, interrogation, information procedures, and evidence preservation and storage, which can be used to address these factors.
