Thanks for your response as well.

When you point out that you "don't know a lot of black people that committed crimes against white people" in the "low income area" where you grew up, that makes total sense, of course. Most people commit crimes within their own communities and often against people they know.

But I didn't say that black people commit more crimes against white people than they commit against other black people. What I said is that when you look just at interracial crime, black-on-white crime is a lot more common than white-on-black crime. To make this more concrete, just imagine a white person walking through a poor urban black neighborhood and a black person walking through a middle or upper class white urban neighborhood (or suburb). Who is more likely to be the victim of a crime?

It is sad that this old man had in his head a stereotype of a "black thug" that he acted on fearfully and impulsively. I would want to live in a nation where such stereotypes don't exist. But to fix that problem, what we have to do is fix black poverty, which is at the root of the issue ... since disproportionate black poverty is the underlying cause of disproportionate black criminality. We're not going to fix anything by going after people's "implicit biases" because such biases are no more than direct results of living in a certain kind of reality in which certain groups of people are more likely to have certain negative or positive attributes. We need to fix that reality, not the (unfortunately accurate) image of it in people's heads.
