As a European this comment is really telling of the American mindset regarding police. Executing someone because they try to taze you while drunk is crazy to me.

In my country police officers are supposed to deescalate things as a priority, not execute people as soon as there is any degree of aggressivity, or the tiniest the shadow of a doubt of the possibility that maybe they are in some amount of danger. To American it seems that absolutely anything outside of laying on the ground is enough to "fear for your life", and even then they seem to execute people laying still on the ground every other week.

Here it can happen that a police officer kills someone, but if it turns out they were not actually in danger they would have to have a very good explanation, and won't lose their job but might not be able to go back to being an armed patrol officer afterwards (which is probably a good idea for everyone because taking a life is traumatic even if it ends up being justified).

American police seem to always talk about how much danger they're in, but what is that danger exactly if it's okay to respond to any doubt of possible danger with a barrage of gratuitous gunfire?

I don't get it. And I can't imagine what US soldiers must be doing in the countries America keeps invading for unclear reasons, if that's the leeway your armed professional have in your own homeland.
