I have long believed that black Americans were must less likely to produce serial murderers than other racial groups. I speculated there might be several reasons. The legacy of racial suppression, when black crimes were punished more harshly than white crimes, might hold down crimes that would attract a lot of publicity. And black serial murders were accomplished, so to speak, by gangs and largely contained inside the black community or, more recently, in the conflict between black and brown gangs. My speculations were probably off the mark. Several spectacular instances of black serial murder, the snipers, John Muhammed and Lee Malvo, and now Anthony Sowell of Cleveland, suggest we need a a new theory to account for black serial killers. I think their appearances are more than purely a psychological phenomenon and point to sociological and cultural conditions. Does anyone have any ideas?
