A powerful day with Prof John Grieve and Prof Jonathan Crego, taking Masters students studying Criminology through a Critical Incident workshop using 10kv to capture their decision making. This whole day event looked at the need to recognise early the criticality of incidents and be able to record detailed rationale in the deicision long of the actions taken and their likely consequences. The group debated the significance of both single incident and the links between them. Ably supported by their course leaders, the debatge considered ECHR, legal and political context.
