One guy got beat in the head with a metal bat. That's potentially lethal force. If he wasn't wearing a helmet, he may well have died. No arrest for this assault, or for the woman that maced the downed man after.
I'm not 100 percent on your side as you seem to advocate proactive self-defense. On video I saw it seems plausible that Reinoehl was targeting Danielson to get even for something earlier, not defending himself/his friend. But witnesses say that Danielson had just used bear spray? And that baton, and that pistol. He wasn't looking for a card game. I can imagine a scenario in which Reinoehl could beat that charge.
I can also picture him standing on the sidewalk by his car with his hands in the air while holding a pistol, prepared to drop it. See, here's my gun, here's my hands, I'll go peacefully. Of course I can't say it happened that way. Maybe he leveled it at marshals and they went all Bonnie & Clyde on him.
In another thread I saw many pictures of heavily armed black militia members and my visceral reaction was unexpected. I thought ... well, good. Don't let white shows of force go unanswered; come prepared. And well-trained. And well-disciplined. But at the same time - that's insane. I disagree with your general position as I understand it; I wish everyone would just stay home. No fires, riots, looting, shootings, baseball bats, pepper spray, teargas, bear spray; no flex batons, paintballs or semi-auto rifles and no handguns please. No shoving, tripping, less-lethal projectiles or teargas. No going after a guy that maybe went after your guy earlier. No Tube-style sucker punches, no bags of soup, no back-and-forth taunts.
I have never been violent. I've heard it can be cathartic. That scares me. I think it probably helps Trump. But seeing heavily armed black men doesn't bother me any more than seeing heavily armed white men. I begin to see your point of view.
