racedo,
I'm not sure I follow your point, if HET are investigating the conduct of all sides, as it were, then they are surely wasting their time investigating either the PIRA, OIRA or any other Republican Terrorist/Resistance Group, because they are immune from prosecution. But they seem to be able to pursue British Soldiers whom I would have thought it was very difficult to prove that they acted with as little regard or consideration as the PIRA, OIRA, INLA or which ever other anti-British organization in Ulster.
I think anyway???
