I have some fun below with the Dave Barry-ish Florida special prosecutor lady overcharging George Zimmerman with 2nd degree murder, but it's worth keeping in mind (because nobody else will) how this is the mirror image of the Jena Six brouhaha.
As you'll recall (although nobody else will), Sharpton, Jackson, and Obama were all up in arms in 2007 about the prosecutor in Jena, Louisiana charging six black youths with Attempted Murder for their stomping of an unconscious white youth. This was the Most Racist Thing Ever according to the prestige press brouhaha.
But it turned out that a local reporter named Abbey Brown had already gotten the real story, which was that the six stompers were the stars of the high school football team in this football crazy town, and, with the assistance of their coaches, had been getting away with a "reign of terror," as a local minister phrased it. Mychal Bell, the All-Stater who was their leader, had already been convicted three times in juvenile court, but that hadn't impeded his playing time. The prosecutor's ploy of overcharging them was to get them out of the juvenile justice system and into the adult system, where they wound up with modest sentences that at least made an impression on them.
This is not to say that blacks are never the victims of racist injustice, but that crime stories involving blacks that the prestige press gets most worked up over (Dominique Strass-Kahn, Duke Lacrosse, various campus hate hoaxes, etc.) turn out, with remarkable regularity, to be travesties.
