Because this doesn't qualify as one.
Sorry, but if you walk onto a school bus with a knife intending to stab someone, then go ahead and do it nineteen times, there's a significant amount of hate involved there somewhere.
The "hate crimes" bill is claimed by Democrats and leftist gays to be necessary because we are at the mercy of a system of law enforcement, judges, and juries that Democrats and leftist gays claim is so underfunded, incompetent, and prejudiced that it cannot render verdicts correctly.
Therefore, the Federal government should fund investigations, the Feds should prosecute these cases, the Feds should demand minimum sentences, and the Feds should, at their discretion, re-prosecute a case if they think the first verdict or sentence wasn't good enough -- or, to use language directly from the bill, "left demonstratively unvindicated the Federal interest in eradicating bias-motivated violence."
Except in this kid's case, where he gets none of those -- because he's not a member of a protected class.
I don't think it's going to cost Pemiscot County any less to prosecute this because he's not. I don't think it's fair that his lack of membership in a protected class means there's no guarantee of a minimum sentence, or that the Feds won't intervene if the sentence or investigation isn't up to snuff.
And I especially don't think it's in any way fair that the Federal government has an interest in eradicating violence against members of protected classes....but not against him.
