Oy. Not this crap again. Zimmerman wasn’t chasing Martin with a gun drawn like some Hollywood douch. He was on the phone with the cops trying to give them an accurate location, and backed off when asked by the cops to do so. He was then confronted my Martin, who by then was itching for a fight. The gun only came out when Zimmerman reasonably perceived his life was in danger.
For Rittenhouse SYG might have applied if he’d shot someone that was trying to assault his position and was refusing to back down, but he was running away and trying to avoid a fight when his pursuers forced his hand. He wasn’t standing his ground, he was trying to get away.
You are not understanding the difference between SYG the principle and SYG the procedure, whereby in FL a Judge can determine a person is immune from prosecution without ever putting tje case to a jury.
A SYG hearing, again, is one where you cannot be convicted, but if a Judge finds you were lawfully exercising a right to self defence, further prosecution is barred. You do not need to risk a jury not buying your story in order to defeat the charge before trial in FL.
The fact that Zimmerman had that option available and did not take it is the best refutation of your statement of facts in his case.
