Everyone should check their state laws regarding the use of deadly force. EVERY STATE MAY BE DIFFERENT. For instance, this link shows some Q&As for Florida:

Displaying a weapon or shooting into the ground may be against the law in your state.....depending upon what the bad guys are doing. Shooting someone running away or driving away is almost always against the law....they have ceased the threat upon you.
Read the law, if in doubt ask someone like a CCW instructor. Dont rely upon street corner law...it could bite you big and you might become a cellmate of the guy who stole your stuff.
I may be pro gun and think all bad guys deserve getting shot but the law gives us specific rules within which we must operate
