To address the edit, I think part of the US’s problem is that you are already on the slope, and have been for a while. Violence has been normalised and accepted (and legalised as you’ve pointed out). I’d like to beleive you can reverse course, but it certainly doesnt seem likely.

I dont have any answers for you or op, but if it were me, I would focus on the defence and protection of my family/community first, rather than searching for retribution. I know that sounds hollow and empty though.
