I didn't read this thread fully so forgive me if this is a repeat.
Al Sharpton and his cronies are provocateurs that make money off of their supporters. When he can fan any situation into a racial one he will, even when they clearly are not (zimmerman case).
In the school bus beating the victim is white and Sharpton cannot profit on this one so he remains silent. Anyone who thinks Sharpton is about justice needs his head examined.
Had the victim been black and the 3 boys doing the beating white you would never hear the end of it. Even our President would find it necessary to comment.
