I don't understand the relationships between SES, culture, and crime, but I'm baffled that we pretend that veneration of gang life in inner city communities can't possibly factor into the equation even in a small way. To head off the stupid "white people listen to rap too!" false equivalence, crime worship can't be reduced to music selection, it's (by definition of "worship") a way of life. I guess I don't think we should rule out a cultural cause; it's not like we need to say "every black person worships criminals" or "no white people worship criminals"--if culture plays a role, I hope we can be mature enough to recognize that it's not a binary proposition, and can engage it earnestly and compassionately.
