Not necessarily only that he wasnt one of the planners  According to The Squad he was arrested in Vaughans Hotel because he wasnt registered and he hadnt a toothbrush  He had come with Peadar Clancy and then been forgoten about  The question is if Clancy went to Vaughans just for an IRA meeting why would he bring a civilian Doesnt it seem more likely that he was in Dublin on IRA but not Bloody Sunday business
