A British author has written a play based on the Saville Inquiry into Bloody Sunday when 13 Derry civilians were murdered by the British Army.
Richard Norton-Taylor, who has already written plays into the investigation into the racist murder of black teenager Stephen Lawrence in 1993 and the Hutton inquiry into the suicide of British weapons scientist David Kelly, has now condensed millions of words in inquiry transcripts into 78 pages of script.
On January 30, 1972, members of the British Army's paratroop regiment opened fire on unarmed civil rights demonstrators in Derry, killing 13 people. A 14th victim later died from wounds.
Mr Norton-Taylor who is also security affairs editor at the Guardian newspaper, warned the Saville Inquiry was unlikely to satisfy all the affected families but would hand out criticism of some senior officers involved.
"For some of the families it will help as a closure," he said. "But some of the relatives will want prosecutions of the soldiers, although I don't see any way there will be any."
He said the Bloody Sunday case highlighted both a breakdown in the chain of command and the confusion over whether the protesters were armed and posed a threat.
"Even though we are talking something that happened over 30 years ago, the lessons are clear - that even highly trained and disciplined British troops can get involved in very dangerous shooting matches against civilians," Norton-Taylor said.
"This is a running problem, and military commanders in Britain are increasingly concerned that they are being asked to be policemen, whereas soldiers are trained to shoot to kill and it's a very difficult mix," he told said.
"We've seen the consequences in Iraq, where a number of British solders ... have been charged or face the prospect of being charged for the abuse, murder and injury of Iraqi civilians."
