Consider this. BLM and the other SJW want every police department either gone or under the thumb of an oppressive Fed DOJ, (most of which I might add, never had their ass in the grass one day).
So, whenever there is a police shooting, they already have resources in place, gin up the locals about “white officer, shot in the back, hands were up, etc” and then at the end the day, that agency is under investigation by the DOJ, predictably found to have violated rights, and under a consent decree, thereby federalizing them.
I would also say to the Alderman Kalifa Rainey, who undoubtedly will use this as a future platform for mayor, like Antonio French is doing here in St. Louis, that if he is under the oppression of the police, the answer is to the tell the police not to come to his constituents neighborhoods. Handle it yourself Alderman, form your NBPP protection squads and see how long that goes.
