It's the threat that he was going to shoot Hayes and will smith having a loaded gun in his vehicle that will set this guy free. "Stand your ground law"

Negative; You can't go looking for a fight and then shoot someone and claim stand your ground. That's like someone threatening you, but leaves the area. You go kill them and claim self defense, doesn't work that way...

Now if Will would have hit him and jumped out with a gun in his possession, then you have the right to "stand your ground"
