I don't disagree with that position. There's been an egregious abuse of personal and institutional power, no doubt. The police force has turned from "serving and protecting" to something that more closely resembles the military without any of the discipline or training while taxpayers are busy bailing out the offending officers through sovereign immunity. They are rightfully getting taken to task by the public for their indiscretions, as a whole they deserve everything that they've gotten and then some. I don't trust the police, not even a little and im a white guy that makes pretty decent money. I can't imagine how poor POC must feel.
Still, if the black lives matter wants to changes hearts and minds or win sympathy to their cause - they really need to look in the mirror and get a handle on the black on black violence. It just sort of rings hollow that the community is demanding folks respect black lives when the community doesn't respect it themselves.
