The fellow robbed this person at gunpoint and used deadly force which probably constitutes quite a few felony offenses. It the guy was still in possesion of his firearm then the SUV constitutes deadly force vs. deadly force. Basically a part of the "castle" doctrine that was recently passed in Florida. The vicitm had no duty to retreat and you can stand your ground and fight back. So in Florida if you use deadly force to commit a crime against an individual your fair game for the victim if you dont surrender.
I havent read all the circumstances but if the felon had dropped his weapon and assumed a submissive position and then the guy took him out then that might make for a case against him. If the felon had his pistol on him when he was hit he was still capable of using deadly force,too bad for him as the law doesnt require you to be shot before you can defend yourself if you are in fear for your life and the perp is capable of using deadly force.
