The black kid said that the white kid grabbed him and that he stabbed him in self defense.
Of course, it's impossible to justify stabbing someone to death over being grabbed in the stands of a school event. His response was very disproportionate to the offense.
Now, he might have an argument IF he was walking down the street in the middle of the night and he was suddenly accosted.
I think it should be MANDATORY for students to take field trips to police stations, courtrooms, jails, prisons, ER's, and cemeteries so that they can see and hear horror stories like this in order to give them some realism.
Many lives were ruined over stupidity.
