In summary, it’s a question of whether Colie’s response was proportionate to Cook’s threat. We’re going to disagree on that, in fact I suspect most American’s will disagree with most non-Americans on this. Ultimately the (American) court will decide.

I agree that Cook is the asshole here and deserves what he got, from a legal perspective though I have to disagree that shooting Cook was proportionate to the threat.

You describe Cook as the attacker, but there was no expressed threat of violence, only that he was big, and aggravated. Cook didn’t die but easily could have.
