Zimmerman didn’t use the “stand your ground” law. He based his defense on classic self-defense.
But they keep trotting this out because from day one the Left has been determined to get rid of this law and have used any propaganda tool they can find including outright falsehoods.
The libs want everyone dependent upon the government and the police to protect them. They do not want private citizens to be able to use deadly force with a firearm at all to defend themselves. Thus, getting rid of SYG laws is just a first step in that process using falsehoods.
