I'd wager that it isn't just genetics. The US endorses and even promotes criminality via cultural outlets, music, movies and also treats blacks as they are somehow owed a living. As they are somehow destined to fail no matter what as the system is against them. Also high crime rates correlate with a large wealth inequality. So from their perspective, why not commit crime? The system is against me and I have to survive somehow. why wouldn't I take whitey's phone, he's part of the oppression that got me here. It's because of him I can't afford my home, so now I'm going to burglarize his.
