by the courts through cases. This law is fairly new so I don't know what well established case law there is on it. But there's a lot you can do to eviscerate a law through how it is "interpreted" by the court. For example, a case could establish that if you, say, choose to pursue a person who you have already assumed was an armed criminal and against the advice of the 911 operator YOU called then you aren't able to invoke SYG. Something along those lines. A lot will depend on the actual evidence as to whether SYG is even an issue-that will be decided at the hearing to determine whether GZ is immune from prosecution based on SYG. Beyond that, I honestly don't know how it works, i.e. if the hearing determines he's not immune than does SYG still act as an affirmative defense? No clue-never done criminal work so a little beyond me.
This might help a little on the process:
What happens now that Zimmerman is charged in Trayvon Martin death?
http://news.blogs.cnn.com/2012/04/11...ath/?hpt=hp_t1
Excerpt:
Step 5 Defense files a motion to dismiss based on Florida's stand your ground law
If Zimmerman is charged, he is entitled to a pre-trial evidentiary hearing on whether he is entitled to the immunity based on the law. [before a judge only]*
The burden at that hearing is on the defense to prove by a preponderance of the evidence (more likely than not [that is the standard of proof]*) that Zimmerman was justified in using deadly force.
In Florida, an individual can use deadly force anywhere (with no duty to retreat) as long as he/she:
1.is not engaged in an unlawful activity;
2.is being attacked in a place he/she has a right to be; And
3.reasonably believes that his/her life and safety is in danger.
The judge decides whether Zimmermans actions were justified, and therefore entitles him to the stand your ground immunity.
1.If the judge finds the force was justifiable, then the charges are dismissed and Zimmerman is immune from further criminal prosecution and possibly, civil liability.
2.If the judge finds the force was not justifiable, then the charges against Zimmerman move forward.
If the judge rules Zimmerman is immune, the prosecution can appeal that decision to a higher court.
