Then a plea deal for third degree murder would be appropriate. Also, if Zimmerman intended to kill Trayvon (which is certainly depraved) but did not premeditate the killing, then that's second degree murder. It's a good fit. Let's see if the prosecution can make a case. Again, those definitions can be mooted by the "Stand Your Ground" Law. If so, Zimmerman would be a fool to accept a plea deal. He'd win at trail. All the defense would have to do is prove he met the criteria for Florida's "Stand Your Ground" law.
