This I can get behind. They tried to take the crowdsource mentality of Occupy and apply it to a different movement. The problem is they took the part of Occupy that didn't work so well (leaderless, groupthink mentality) and tried to pin it to the only part of BLM that did work initially (the message that Black people were being disproportionately targeted/killed by police) until the former ate the latter.
My pasty white guy take on this is simple: When you remove, or are perceived to have removed, all possible forms of legitimate accountability for people in positions of power, the only thing that the people are left with is vengeance. I think a viable solution can be found to make everyone push back from the edge a bit, however that solution involves the PD's doing something that they really don't like: admitting when they're wrong. There are so many layers of protections to hide behind; qualified immunity, Garrity, the Union, and even each other that to the general public it's almost impossible to determine where an investigation is at, or if they even started one in the first place.
