Black culture is more violent for a number of reasons. Liberals and their egalitarian ideas centered on race envy, social programs that breed dependency, their war on the nuclear family, and their suppression of capitalism and economic growth pretty much ensure violence.

Minority Behavior in Schools Mirrors Black-Hispanic IQ Gap
But every act you cite, has been supported and funded by Republicans throughout the the last fifty tears, even those years with Republican majorities.
Folks like to think that the federal war on the black family was all from the left. Quite the contrary, it was a completely bi-partisan effort.
And to be brutally honest, the dependency programs and family destruction were approved overwhelmingly by white supermajorities in Congress.
Whether “well-intentioned” or not the truth is the white conservative you may have been voting for all along is just as quilty as the liberal for providing the means by which the black family holocaust has occured.
I agree, but I throw in this angle...
Crime is an economic decision. Take the Ted Bundy crazy types off the table for a second, but when jobs are scarce, and wages low, you make the economic decisions to sell drugs, steal, and sell stolen goods. These activities have occupational hazards and risks of getting shot.
Drugs and violent gangs is not really much different than Prohibition in the 1930s when bootlegger gangs shot up their competition for turf and market share.
