Since 1969 there have been over 1,000 deaths in police custody in Britain. No police officers have ever been successfully prosecuted for manslaughter. The only case which led to any successful prosecution was the first such death - that of David Oluwale in Leeds in 1969, when officers gave evidence that resulted in convictions related to the assault on Oluwale but not to his death. Since then the Crown Prosecution Service (CPS) has found no case to answer in all cases of deaths in police custody. Through documentary footage and extensive interviews with the families of the victims, the filmmaker charts the deaths of people in police custody as well as the consequences of these deaths.
