Yes there is a problem with violence in the white communty. The majority of homocides in the black communty are economic based. It's poor people fighting over scraps. That's not a black in America problem, it's a poor in the world problem. Anywhere you have poor people you have high instances of violence.
Black people are disproportionately living in poverty in America, therefore they disproportionately exibit poverty problems
White people in the other hand don't have the problem of living in generation upon generation of poverty, therefore their violent crimes should be a lot less than they are. There is something going on in the white communty, that's turning young white males violent, and you do yourself a disservice by ignoring that fact and pointing the finger at poor black folks in Chicago.
