I know attorney's dont always get to choose their cases, but I would not want the prosecution's case either. Not good judgement, in my opinion. Btw, I know you can't control your witnesses do once they take the stand, but to me it seems like the witness prep for the prosecution was terrible.
The problem with the cops is they decided to tell the truth.
The problem with the lesser included offenses is that every theory requires the jury to find Zimmerman started the fight and the evidence as it has come in just doesn't support that.
