The New York Times reported that Lorenzo Gulyard of Kansas City was convicted today of murdering 6 prostitutes in the 80s. (They don't show his photo, but I found this one).
Black criminality is so conspicuous in American society, people have hunted around to find some kind of terrible behavior that whites specialize in. Serial killings have been a great one to latch onto. For example, I have heard black comedians say something like: "Us black folks might get violent once in a while, but when whites kill, they go apeshit." According to research by Eric Hickey, 20% of American serial killers have been black. That figure is two times their historical share of the U.S. population.
People also push the idea that it's whites who are the child molesters, and they put this all together to say that non-whites commit the cool crimes like gangbanging, while whites commit sicko crimes. But not only is the serial killer stereotype incorrect, so is the one of the white pedophile. While it is true that, according to the oft-quoted 1991 survey of state prisoners, almost 70% of those convicted for violence against children are white males, people conveniently forget that this number corresponds roughly to their share of the total male population. It's a bit of a stretch to say, you guys are the child molesters because you equal the rates of other groups.
