[Gordon Booth]

Well put, MargaretR.
No one is saying he was an innocent civilian- he was an insurgent.
So he must have been shooting at them or threatening them with a gun or explosives to identify him as an 'insurgent'.
These men are told you can't shoot a man because he has a gun,you can't shoot him if he points it at you, you can only shoot at him if he shoots at you. If that's too late for you tough-those are your 'Rules of Engagement'. How can you fight the Taliban on that basis?
Our troops are trained to kill to survive-but our Defence Secretary says ' they carry cards in their uniforms with the rules on them in case they should need to remind themselves'. What a fool!
'Hold on Mr Taliban,I know you've just tried to kill me/blow me up/killed my friends but just wait a minute while I get my little card out to see what I can do about that'.
In situations like that things may go wrong sometimes but-
What a way to destroy the moral of an army!
Mind you I wonder how someone can be foolish enough to record and keep film of something that at least in the aftermath of the event they know was wrong and broke the 'Rules of Engagement'.
