A 65 year old retired British soldier Para C faces the possibility that he will be prosecuted for the killing of an IRA leader Joe McCann who was guilty of what were almost certainly war crimes. Meanwhile folks who we know have blood on their hands - notably Gerry Adams and Martin McGuinness, today politicians, but back in the 70s IRA bigwigs, know they can never be prosecuted under a deal agreed with their fellow war criminal Tony Blair. I discuss what happened back in 1972 and the nature of reconciliation and what Adams and McGuinness should do now if they really believe in peace.
