[citation needed] In 1987 McCann along with another IRA member, Sean Savage, murdered two Royal Ulster Constabulary officers at Belfast docks.
Whilst McCann, Savage and Farrell were engaged on 6 March 1988 on a reconnaissance trip in Gibraltar before driving in a car-bomb, soldiers from the Special Air Service Regiment wearing civilian clothes confronted them in the streets of the town.
[4] Savage was walking separately behind McCann and Farrell within eyesight distance, and seeing them ahead being confronted and fired upon, fled, running several hundred yards back into Gibraltar town closely pursued on foot by another Special Air Service soldier, who caught up with him and shot him dead also.
The documentary also interviewed civilian eyewitnesses to the shooting of the Provisional IRA members, raising questions about the veracity of the British Government and its involved soldiers' accounts of it, focusing on whether the three IRA members had been offered the chance to surrender by the soldiers confronting them before they had been fired upon.
The funeral immediately descended into chaotic scenes, as a running fight occurred between the lone gunman firing a handgun and throwing more grenades at a group of mourners, as they pursued him through the cemetery's grounds.
