I never said there is a law in Georgia allowing a warning shot.
I pointed out - correctly - that warning shots are not shooting at someone.
There is no law in Georgia against firing warning shots, either.
It is unclear whether or not a warning shot was fired to deter the deceased from attacking the two men in question.
It's possible, or perhaps both shots were fired in self defense directly at the assailant. I don't know, and neither do you.
He was not attacking the two men. He was jogging around the outside of their truck. But you know that. You are just trolling. Have fun.
