Well, Teribus, I suppose it depends on who you want to listen to. In that long and elaborate (and ramshackle) justification of yours for the murder of Joe McCann, you could have mentioned the report of the Historical Enquiries Team into his death. I note that that organisation came under heavy criticism eventually - for reports that were biased in favour of the army and police. Maybe in Joe's case they saw something that you refuse to see, huh? As I say, when the court case is over I just might remind you of your own bias on this. Wiki:

A Historical Enquiries Team investigation into the killing of Joe McCann found it was unjustified. The report stated: "The HET considers that Joe's actions did not amount to the level of specific threat which could have justified the soldiers opening fire in accordance with the Army Rules of Engagement or their standard operating procedures." The report was welcomed by his wife and children.
