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.
