Why are some African American youths using Twitter to form flash mobs to loot stores? Why are some playing "knockout king" using, among others, white liberal bloggers' heads as punching bags?
My assumption would be: because they can.
Others, however, seem more shocked. They ask: Wasn't voting for Obama supposed to stop this kind of thing?
Yeah, well, maybe. Or maybe the rationalizations for Obamamania weren't quite as foolproof as they had seemed back in 2007-08.
