It is already being speculated that Zimmerman will be offered a lesser-charges deal and will take it. One reason: who's got money for defending the case, or appeals?
I don't think that Zimmerman can expect any help on that from the NRA or other pro-Stand Your Ground groups. If SYG ends up "protecting" Z, we can expect that to add fuel to the already blazing anti-SYG fire.
If, on the other hand, Z is convicted and is unable to appeal, or pleads out, then everyone can say, "See? SYG isn't bad at all. Even with FL's SYG law, that mean ol' Zimmerman--who shot that nice young man--is going to prison. See? SYG doesn't protect criminals like him."
As earlier reported by the Examiner, even as august a scholar as Dave Kopel has insisted that SYG offers Z no protection.
In order to protect SYG, they have cut Z adrift: bon voyage, sucker.
Personally, it is not clear to me that Z committed any crime in exiting his car and following M: I don't think he had mens rea, and he was standing "where he had a legal right to be", walking back to his car, when the fatal confrontation started.
If SYG doesn't protect Z, I'd say it protects very few people. And the NRA seems fine with that.
Question: are we over-estimating the value of SYG laws in keeping those who shoot in SD out of jail? Is the NRA going to be happy to sacrifice Z to the cause, if that helps keep SYG laws standing in FL and other states?
