It has more to do with poverty and hopelessness than it does with race. And the more we build societies based on "survival of the fittest" rather than cooperative communities, the further down this wormhole we can expect to go. When you build a society based on the law of the jungle, you must have the fortitude to accept the reality that sometimes, the jungle is going to come into the living rooms of the "winners" every once in a while. Combine overpopulation, basic resources out of economic reach, failing education, lack of jobs that can sustain basic survival and then toss in hopelessness on top of it and you have a sociological experiment whose conclusions are foregone.
Really. What the **** do you expect?
