If the obviously guilty Casey Anthony can be acquitted by a Florida jury, the obviously not guilty Zimmerman can be acquitted by a Florida jury.
There is always a chance of a conviction. I could be completely wrong. But the prosecution is nowhere near "beyond a reasonable doubt."
I also believe that there will be very little civil unrest if he is acquitted.
Further, Zimmerman will be in danger if acquitted, but only temporarily. His critics have very short attention spans.
Hope you were trying to be funny.........
