Adams led the IRA's General Army Council during the 70s and early 80s. He practically re-invented the Provisional IRA and was instrumental in making it vastly 'better' (more effective). A true terrorist mastermind if ever there was one. Sadly, he'll never go down for anything he either did, commanded others to do, or had operational knowledge of. The disappeared (and there were many), were victims of a regime that habitually maimed, tortured and murdered arbitrarily. Adams was deeply involved in this. There are plenty like him who will never face justice. And just to bring some parity to this rant there are plenty on the Loyalist side and within the British establishment who will equally escape justice.
