I cannot answer for the civilian or the police members of the team. Those in the military would have had a role to advise the senior military staff in NI on options based on the intelligence sources that they would have had access to. Those senior military could then advise the politicians etc etc. My point is that those who died in the crash, Majs and Lt Cols would have been on a 2 year tour (probably due posting to another theatre) and not have had the influence to block a particular governement policy. Very few junior to middle ranking officers have that influence in UK.
