George Zimmerman's attorneys stunned court observers today by deciding to skip a "Stand Your Ground" hearing slated for April that might have led to a dismissal of the charges in the shooting death of unarmed teenager Trayvon Martin.

Under Florida's Stand Your Ground law, Zimmerman is entitled to immunity and if he can prove he shot and killed Martin Feb. 26, 2012 self defense. If self defense was determined, all criminal proceedings would have immediately stopped, and Zimmerman would have walked free.

But Zimmerman's legal team also risked the possibility that the judge would reject the motion and the hearing would give prosecutors an opportunity to pick apart Zimmerman's testimony.
