What provoked the attack? Article implies the attacker was angry with the mother over something to do with her losing her job.
Why did no one in the crowd come to the aid of the mother? Racial solidarity against whitey?
It took me about 5 viewings of the video to get the gist as to why the black was pissed at the white woman.
According to the pummeler, the pummeled was spreading some sort of rumour that put her in a bad light with the manager and had almost cost her a job at McDonalds.
I got the impression upon watching the video that the two women know each other. Also, it is sad to note that the little boy does not really respond like a child who is not used to seeing this sort of violence. I suspect that the real cause of the attack is because of a man that both of them are involved with.
