In Man Alive tonight policemen, lawyers and members of the public discuss the present situation and consider the future. Most of us believe and are thankful that Great Britain has probably the best police force in the world. Nevertheless there are complaints about police behaviour; allegations of violence; accusations of racial discrimination, corruption and prejudice. When a complaint is made by any member of the public against the police it is made to the police, investigated by the police and judged within the police force. Many policemen are discontent with this system which, they say, sometimes penalises them while under investigation and frequently hampers their desire to be seen to be just. How well does the present system work and what effective changes could - or even should - take place? Is it fair to either side that police are cast in the role of both judge and jury when it comes to complaints about their own behaviour?
