Justice?

Black chick spits on white guy, he punches her out and he has to spend 6 months in jail. Two witnesses support white guys story, witness that supported the black chicks story apparently wasn't any where near the front of the store. All the white guy was trying to do is hold the door for the black chick and her child. Now it comes out she has a history of this kinda crap. By the way, why wasn't the black chicks husband and/or the child's father holding the door? Oh never mind.
