He wasn’t provoking anybody, he was straight up giving orders to a crowd of protesters. As an armed man. Who was not in fact a cop.
“self-defense (in my view) involves the defense of others as well”
By the very definition, it does not. Your view is both wrong and utterly irrelevant here. Since you have shown to have no empathy for the protesters and don’t even try to have an unbiased view of the whole shitshow, you don’t really get to have a “view” on this. You are acting a tribalistic shitape instead of at the very fucking least trying to understand and address the grievances of the people involved.
“Christ, if a young girl dresses provocatively and tells you to fuck her, do you take the bait or do you use your better judgement and just ignore her?”
BZZZ WRONG AGAIN, fuckhead! The right answer is: Neither. You try to find her parents/guardians and explain why is she trying to sex up an adult. Failing getting a proper reaction out of them you try to make cps at the very least aware of the issue. To translate it here: You address the fucking root causes, like having no legal problem with shooting to kill in so-called self-defence.
