Belfast what in heavens name are you on about?
"Oh dear. Can we try to be reasonable? Saying a thing is so don't make it so". Martin McGuiness tried that, saying he was not in the IRA and wanted people to believe it probably most of all himself.
Do you honestly expect people to believe that the IRA do not know who their dissidents are. They have to know, to break away from the IRA you have to be part of it in the first place.
SF call for all sorts of inquires,why not into the IRA and it's spin offs. Here is a starter who was responsible for the murdering and disposing of so called informers.
Why are those who were told to get out of Ireland not coming back? Who told these people to leave and who is going to enforce the so called expulsion order if they do come back?
If these people were to come back en mass would we see a spate of punishment shootings or killings?
