As noted, we're all against unwarranted police killings of civilians. I don't think we need to say that, really.
We're all against rioting and arson and looting and anything else of that ilk that is illegal.
I suspect we all support good police officers. I suspect we all understand that any large population of humans will have some who are "bad", either incompetent, nefarious, sociopathic, on some power ego trip, whatever.
There, I've said it, if anyone disagrees, fine with me. If not, it's said for us all, here.
