Who says black people don't protest the violence in their own community? The Atlantic did a write up on this exact subject right around the T.Martin issue.

Perhaps the problem is that people are foolishly equating 2 separate issues?
First, the media doesn't cover blacks protesting/fighting violence in their own community to the same extent that it covers more racially charged violence. But the lack of media coverage doesn't mean that such efforts aren't taking place.
Second, citizen on citizen violence is very different from violence perpetrated by the government in violation of it's own rules. Black on black crime, while reprehensible, is going to be appropriately punished through the usual methods of crime punishment. But when the cops or some other authority figure commits violence against the citizens, it's less sure that same government will adequately protect the harmed citizens.
Anyway, the whole idea that the black community doesn't protest black on black crime just isn't true. It's another false narrative that some people believe because it's fits their skewed image of what the black community actually values.
