Why do you guarantee it? If there are, they don’t care enough to do anything about their community shitting the bed, or their numbers aren’t big enough to give them confidence in their position. From polling, blacks seem to want to have their cake and eat it too w/r/t police: They want cops to be there to keep them safe but not to have any power over them because it’s unfair, racist etc. to arrest them or enforce the law when they break it.
I think a larger portion of blacks may simply not care, too caught up in the daily hustle of survival/their own dysfunctional lives to be engaged in politics, and if they riot it’s because it’s an opportunity to get free shit.
