The real culprit in this story is whoever used the epithet "nig@#r." Won't be too many years and perps who utter that word will be shot on sight...
The racial comment is driving ALL of this. When something like that is said in that tone, it is an attack on 30 million people, not just one.
I am inclined to believe that that players did something, although I'm not sure the right ones were picked out. But I will readily admit this is due to my own bias, because I don't know the facts.
I just wish the defence would stop avoiding answering whether or not this was said.
