They're highly organized. I think perhaps a better word for their actions is "unjustified," or if you're feeling less charitable, "unjustifiable."
I can't say anything about the situation with the Minneapolis PD, but it seems like it has a major training problem, there was also the case a couple of years ago of the cop that shot and killed a (white) woman in her PJs who was reporting a possible crime out of the window of their patrol vehicle.
