I was actually thinking much longer term on a much broader basis. If the blacks continue acting like this and not policing themselves then the other races (much as I abhor that usage of the word) will eventually have to eradicate the blacks. Kind of like we will have to eradicate moslems.
In the short term it may be messy but coming down on lone white people who defend themselves from a black mob will only cause more white people to arm themselves in self defense. Eventually it will be dangerous for a black person to associate with another black person as the non-blacks will be getting really jumpy.
In the long term, the leukocytes (white blood cells...how fitting) kill off the offending cells that threaten the body.
