Did you read the article? Most of it was not mentioned on CBS tonight (such as the racist remarks that caused the beating or that he went to a social function that night). The problem at hand is the double standard in the justice system.
Contrary to what you clearly believe, saying something racially insensitive is not justification for aggravated assault.
There's also the part where Bailey got beaten by white people, to whom nothing was done, and when he was threatened by a white guy and took the gun away in self-defense, resulting in him being charged with theft of a firearm while the white guy, obviously intending to threaten him with the gun, had, again, nothing done to him. Both whites and blacks did equally bad things here, but the black people get criminal charges while nobody seems to care about the white people.
If the events described in this article are fully accurate, I don't think it can really be argued that there isn't some sort of double-standard going on.
