FILE - This is a Sunday, March, 8, 2009 file photo of police forensic officers as they examine the scene at the Massereene army barracks in Antrim, west of Belfast, Northern Ireland, after two British soldiers were shot to death and four other people wounded in a drive-by ambush that politicians blamed on IRA dissidents. A man who was convicted of the Real IRA killing of two British soldiers in 2009 has had his murder convictions overturned Tuesday Jan. 15, 2013 by Northern Ireland's highest appeals court. Brian Shivers last year received a 25-year prison sentence after the trial judge found him guilty of murdering the soldiers, who were shot to death as they collected pizzas from outside their army base in the Northern Ireland town of Antrim. They were the first troops killed in the UK territory since 1997, the year that most IRA members began a cease-fire. (AP Photo/Peter Morrison, File)
