The white man should definitely be charged with a hate crime, instigating the whole affair by using the N-word, having a miniature noose in his pocket, wearing a t-shirt with a confederate flag on it, and of course the most serious offense of all, being white.
He was probably thinking of a noose.
Thats about it.
No doubt the youths will claim that he used the N-word, and some members of the jury will believe them.
