Well no it surely doesn’t have a thing to do with “politics” except that surely there wasn’t a single McCain voter among them.
But I mean from a birds eye view what happened? They just happened to get a little knot of misbehaving black punks in the middle of a larger crowd of black people who were behaving themselves? And it could as easily have been a little knot of misbehaving white punks? It sounds like a disproportionate number of (yes, black) thugs, punks, whatever got pulled in through a misguided outreach, disproportionate even considering the dismal state of Milwaukee’s black population.
Nothing threatening them.
Do you think this would happen if they thought the person they were attacking had even a 50% chance of being armed and ready?
No way it would happen.
