Based on the documents that Dershowitz was talking about, I'm starting to think that the reason the special prosecutor charged Zimmerman is because she's not very smart and is not a very good lawyer. She's probably not used to prosecuting defendants with an IQ above room temperature or sparring with good lawyers. If somebody told her to do this, they didn't think it through.
Her press conference was very telling. She seemed energized by the spotlight, downright giddy. Look at me! seemed to be the whole message.
As an attorney in practice for 36 years, I've seen the type.
