So why do you want to deny Martin his rights? The "stand your ground" law says he was entitled to defend himself and had no need to retreat ~ yet, in fact, he had retreated. He'd done everything he could to escape an individual who gave every indication of wanting to harm him.
It's night. There's a cold rain. He's in a strange place ~ just a visitor. He walked over to the 7-11 to buy candy, and still had it on him as he returned to his father's girlfriend's place. He's unarmed.
Zimmerman is roaming around in a pickup in that gloom of night, packing heat, and looking for people he thinks are suspicious looking.
Martin was after skittles. Zimmerman was on the scent of man.
I really think I understand what's going on here and you don't.
The Sanford PD disagrees. Take it up with them.
