Two's in - IMO you are spot on and I congratulate you on a damn good post.
Some readers on here really have no idea how evil the IRA are. (Our wonderful governments might have put them back into a state hibernation for a little while by appeasing cold blooded murderers). FFS our 'democracy' let them all out, gave them pardons and vast sums in compensation. Some reading here still have this misplaced romantic notion of 'freedom fighting' bollox against the oppressive British.
As for theatre specific rules - even more bollox - terroriism is terrorism and the only way to fight terrorism - is with terrorism. I certainly have no axe to grind with what was done - not one single bit. I do have an axe to grind about how many were and still are, dragged through the law courts for far less acts of, so called democracy.
