Once again, both sides in this are hardening their positions. This was not a "schoolyard fight," with the implication that it happens every day with boys hyped up on testosterone. The allegation was that six teenagers beat another teenager unconscious, then kicked him as he lay on the floor unconscious. The kids who did this are not the martyrs they're being made out to be. This deserves punishment. That's why we have a juvenile justice system.
On the other side, the incident was (apparently) part of ongoing confrontations between black and white students, and several black students had been attacked by whites in the near past. The targeted victim had supposedly earlier been engaging in racial taunts.
You'll notice this post is peppered with "alleged," "apparently," and "supposedly." The truth of all of this is rapidly disappearing and I doubt it will ever come out.
But the action of the DA in charging these kids, who are high school students, as adults, and with attempted murder at that, is a vast overreach and a clear example of judicial abuse of power. The allegations of racism here are certainly not unwarranted.
None of this matters. Any just resolution of this case is now irrelevant. There's political hay to be made, and Al "I love a camera" Sharpton will be at the forefront, you may be sure.
