Dershowitz’s point: There’s nothing in the charging instrument that suggests probable cause to believe Zimmerman had a “depraved mind regardless of human life” when he shot Martin. On the contrary, he notes, the facts as stated are consistent with self-defense. (Tellingly, there’s also no reference to Zimmerman’s injuries.) The prosecution can amend the affidavit to strengthen its case if the judge throws it out, but then you’re left wondering why they didn’t submit a more detailed affidavit in the first place.
Listening to talk radio (Larry Elder who is a lawyer), it can be asked of the judge to add a second charge of manslaughter. Which is a lesser charge and can be argued better in front of a jury. What does this do, it makes the prosecutor look tough in front of her constituents, and it allows the city to not be blamed for the guaranteed violence that will come when this charge is either thrown out or a jury returns a “not guilty” verdict.
