Simon Cox examines what happened with the investigation into the death of Ian Tomlinson at last year's G20 protest and asks why no charges have been brought. Outrage has been expressed at the recent decision of the Crown Prosecution Service not to pursue charges against the policeman that struck Ian Tomlinson minutes before his death. And the General Medical Council is currently conducting a hearing into the 'fitness to practice' of the pathologist who conducted the first post mortem on Ian Tomlinson. The programme examines each stage of the investigation, talks to those closely involved with the case, and asks whether the judicial process failed.
