I'm not sure the change is there that people think there is. I would be willing to bet dollars to donuts that had the officers been white, they'd merely be on "administrative leave" while they conducted "an investigation."
But ya, rioting isn't going to do anything. Protesting? Sure, that makes sense, but burning the city down? That's rarely the answer. Hopefully, the people looking to capitalize on something to get up to no good are few and far between so the people who legitimately want to protest can get their message out.
I think what the Tyre Nichols incident does show is that it's a bit less of a racial thing and more of an authority thing and bad cop thing. It doesn't matter the race of the person, if they get drunk on power and authority, they're probably going to abuse it and as they get away with more and more stuff, it's only going to get worse. It wouldn't surprise me at all if this was the first incident for any of those officers with regards to way overstepping the line.
