THE family of an 18-year-old shot dead in 1972 by a secret British army unit have said they are taking legal action against the Ministry of Defence (MoD) and want a new inquest.
Daniel Rooney was gunned down by undercover soldiers from the Military Reaction Force close at St James's Crescent in west Belfast.
The army later falsely claimed he was a known gunman.
A Panorama programme, shown on Thursday night, carried interviews with members of the unit, who admitted that nationalist men were shot even though there was no evidence they were paramilitaries.
The north's director of public prosecutions, Barra McGrory, has asked police to investigate the MRF "on the grounds that criminal offences may have been committed".
Noel Rooney, Daniel's brother, described the 1973 inquest into his death as a "sham", saying none of the soldiers involved gave evidence at it.
As well as a fresh inquest he said the family wanted the soldiers responsible to be brought to court, although he does not think this would happen.
"We would not have any confidence that any of these people would be prosecuted. We would certainly like to see it happen," he said.
"The family are supportive of anything that will get to the truth and the [Panorama] programme helped with that.
"It exposed something that we knew all along. My mother wanted Daniel's complete innocence to be known and wanted a British government apology." He said his mother, who died several years ago, "never got over" her son's death.
Mr Rooney said on the Sunday in September 1972 after his brother was killed, a statement was read at Masses explaining that Daniel was innocent. His grieving family were doubly hurt when the British army attempted to "blacken Daniel's name".
"They said he was a gunman when everybody knew he was totally innocent," he said.
"The guy who was shot along with him, Brendan Brennan, was never convicted of any offence.
"The whole issue is why did police not investigate this?"
Mr Rooney said he was shocked that the Military Reaction Force was "organised at such a senior level".
And he said he was appalled by the "arrogance and ruthlessness" of the soldiers who appeared on the programme.
"They said they would do it again," he said.
"They were quite open and brazen about it."
Mr Rooney's solicitor Padraig O Muirigh also disclosed papers from the MoD which advised that a civil case taken by the Rooney family in 1977 should be settled out of court, partly because a court case could "force disclosure of information about the tactics and methods of the unit".
He said the original inquest "did not properly probe the role of the MRF in his death" and the Rooney family will apply to have a new hearing.
"The soldiers involved were not called to give evidence and account for their actions. The original inquest was flawed," he said.
Mr O Muirigh also said the Rooney family will issue civil proceedings against the MoD in relation to the conduct of their soldiers.
