I'd have to do some math to be precise, but a flaw in that argument is that the vast majority of black crime is black-on-black, and the vast majority of white crime is white-on-white.

So a white person, acting rationally, should fear a white person more than a black person.

A black person, acting rationally, should fear a black person more than a white person.

Of course, that assumes that acting on a racial basis makes sense in the first place. Which it doesn't. As your link admits, murder rates among both blacks and whites are vanishingly low (5 murderers per 100,000 people). So it makes no sense to base your (re)actions on skin color, because murderers are not representative of their skin color.
