Out of curiousity, I asked a friend of mine who is a Crown prosecutor if the Canadian use of force rules were similar. His off-the-cuff answer was that he didn’t think the use of deadly force in these circumstances would be justified, because the guy was fleeing from the cop, rather than posing a direct threat to him, and there was no evidence that he was armed. I think the fact that the shooting officer id’d him solely from the description would have also counted against the use of deadly force, because of the possibility of a mis-identification in such short circumstances.
