This event brings together a leading forensic scientist and a practising barrister to shed light on some of the most sensational human dramas played out in criminal courts. The most famous murder trials of our time depend on the importance of forensic evidence. Angela Gallop has been a forensic scientist for over 40 years spanning the Yorkshire Ripper investigation, the murders of Stephen Lawrence, Damilola Taylor, Rachel Nickell and the Italian banker Roberto Calvi. Thomas Grant showcases the Old Bailey trials that define modern Britain. Notorious for its murder trials, Court Number One has witnessed changing attitudes to homosexuality, the death penalty, freedom of expression, insanity and the psychology of violence. Chaired by crime reviewer Jake Kerridge.
