As usual you are just plain wrong. The overcharging was made by Angela Corey, a conservative Republican prosecutor appointed by tea party Governor Scott. I submit she got exactly the verdict she wanted, thanks to overcharging.
Perhaps that was the endgame. It was a certainly a politically motivated prosecution, not just because of the volatile racial element, but because a majority of Florida DAs hate the stand your ground law. It makes it nearly impossible to prosecute what was once a garden variety case.
I find it hard to celebrate our legal system when we have just watched the state of Florida try to railroad an obviously innocent man to jail for most of the rest of his life, all to placate a bunch of thuggish race hustlers, starting with the president of the country. We saw the state's prosecutors repeatedly violate elementary legal ethics as well as their duty as prosecutors. That duty is not to get a conviction at any costs, but to see that the truly guilty are prosecuted. Their entire case was a blatant appeal to emotion and, sublimally, to white guilt. Their case rested on zero evidence, but wild speculation about what "really" happened. Even their own witnesses make a mockery of their case. As for the judge, she is a stunning disgrace to the judiciary, even in a state with such an apparent low bar as Florida. Her bias was so raw and evident that even a former prsoecutor like Great van Sustrand eviscerated her. The bias was pervasive and non-stop, culminating in a bizarre interrogation of Zimmerman that left veteran trial lawyers speechless. The sole saving grace was the jury. I have to apologize for my fears that these six women would be too emotionally shaken or cowed to do their duty. It no doubt helped that five of the six were either gun owners or had close family who were. Instead of being emotionally driven weaklings, these women apparently knew the reality of life in a tough neighborhood and applied it and not the fantasy version being pushed by the media.
