Zimmerman's best hope,regarding the *state* charges,is that a judge who isn't worried about reelection (perhaps nearing retirement) dismisses all the charges...with prejudice.His second best hope is a couple of hung juries and,after the second one,the presiding judge declaring that the state won't be allowed to try him again.
But even in these best case scenarios,he'll still have to worry about Attorney Corporal Holder.
Actually it needs to end at the immunity hearing before the judge. That immunizes him from criminal and civil action. If it goes to the jury, then even if he is found not guilty, he can still be sued civilly.
