Could be that walked like they own the sidewalk, were told to give some way, mouthed off and got smacked. No way they were just attacked. 
I had six shitskins walking shoulder to shoulder making no effort to let me pass through their wall. I think the dumb niggers were so fascinated and distracted being in an airport. I just walked strait into one of them. He realized at the very last second we both kinda stopped but still collided a little. He was clearly pissed but they were out of their element so I did not get the obligatory gang beating, I would not have done it anywhere else. So gled I did not have to back down to those animals. Fuck those niggers and fuck those bitches, I guarantee they fell they can do as they wish and fuck white people.
