Improving Witness Testimony (Parliamentary Office of Science & Technology, 2019)  explains the latest research about witness testimony. Witness testimony is a written or oral statement given by an individual who has experienced an incident. It is collected during criminal investigations (including through investigative interviews, facial composites and identity parades). Drs Heather Flowe and Dr Melissa Colloff contributed to the content and acted as expert reviewers.
