In many parts of the country, if the District Attorney decides to file charges, he can do so without going to a Grand Jury. I suspect this is the case in Sanford. I guess the District Attorney could still go to the grand jury, but that would like telling them that he doesn't trust his own judgement to review a case, and he would rather that they take on the responsibility. If there is some compelling new information that comes forth that casts doubt on Zimmerman's account of the incident, then the District Attorney can still file charges. I would have to believe that the statute of limitations doesn't expire for a long time in this case, depending on what would be charged.
It's anyone's guess what can happen if the Feds get involved, but they may have to also conclude that based on the evidence, Zimmerman's statement, and the statement of the eyewitness that there are no grounds for filing a criminal complaint. So far, I think that the most likely course of action that is going to be taken is for Martin's relatives to file a civil suit against Zimmerman.
Which may proe pointless. As a FReeper pointed out yesterday, the Florida "stand your ground" law explicitly exempts the defender from any civil damages.
Ha! Martin’s attorneys will go after the Sanford police department. Zimmerman has no money
Thank you for the explanation.
