Hood: a cultural history of a seemingly neutral garment which has long been associated with violence, from the Executioner to the KKK and inner city gangs. Laurie Taylor talks to the America writer, Alison Kinney, about the material and symbolic meaning of hoods. Also, the blacklisting of employees. Dr Paul Lashmar, Senior Lecturer in Journalism at the University of Sussex, examines a hidden history of discrimination. He's joined by Jack Fawbert, Associate Lecturer at Anglia Ruskin University, who provides the most contemporary and widespread instance of blacklisting in the UK - an extraordinary corporate crime which led to over 150 current or retired building workers reaching a substantial out of court settlement with the country's eight largest building employers earlier this year. All had been blacklisted for their trade union activities and alleged political views. How did this happen? Producer: Jayne Egerton.
