Nation's most segregated city marred by racial tensions

There was violence again last night in Milwaukee, America's most segregated city.

Police say body cams show Sylville Smith, the black man killed by police on Saturday, refused to drop a gun loaded with more bullets than the gun of the black cop who shot him. The details will be subject to an independent investigation. But the violent outbreak was the result of racial tensions that have been seething in Milwaukee for decades. That's according to Craig Gilbert, Washington Bureau Chief for the Milwaukee Journal-Sentinel.
