Trigger Point is a powerful two-part series that goes deep inside police culture. In the late 80s and early 90s Victorian police shot dead more than thirty people. In retaliation, three police officers were executed, and a persecuted senior policeman died at his own hand. Eleven cops were eventually charged with murder-related offences and the public, the government and the media all bayed for blood of one type or another. True-crime writer John Silvester investigates this tragic chain of events; the story of a silent war in Australia's most urbane city: the cops, the crimes and the three men who fought to end misuse of police officers' licence to kill.
