You right I should give a better answer than ists complex. But the thread goes in to look at factors such as segregation, density, and poverty. You have many poor people packed in to small places more violence is going to happen. These areas are more likely to have black people as opposed to white poor people who are more spread out, think Appalachia region. Do these factors explain everything, no but they do show it isn't as cut and dry as some try to make it.

Because of time will have leave a that for now.

But my claim was not that I know the causes of the higher Black crime rate, but rather that because of this higher crime rates, some White people have become fearful of Blacks. This would be the case regardless of the underlying causes.

Also [0] is only able to explain half of the crime gap through "structural characteristics". Of course this article would be considered extremely racist by many people in this thread (not you) since it assumes the crime gap reflects actual higher rates of criminal behavior, and not just bias in the justice system.
