Duh! "[A]s permitted in s. 776.012, s. 776.013, or s. 776.031...."Now let me bring to your attention this part of Florida's Stand your Ground law! You can not arrest, detain, etc. anyone unless you have evidence that he was NOT acting in self defense. In other words, the Sanford Police violated Zimmerman's rights simply by cuffing him and taking him to the police station!
776.032 Immunity from criminal prosecution and civil action for justifiable use of force.—
A person who uses force as permitted in s. 776.012, s. 776.013, or s. 776.031 is justified in using such force and is immune from criminal prosecution and civil action for the use of such force,........
As used in this subsection, the term “criminal prosecution” includes arresting, detaining in custody, and charging or prosecuting the defendant.
Now please read the relevant sections and point to where reasonable fear is presumed according to the fact pattern in the Zimmerman case.
