i don't know. Legalities are pretty intrinsic to the situation. Unless I missed something, the shots were on the *fleeing* suspect.
That not cool... These guys are not law enforcement, and we do not carry to help enforce laws.
I am not sure of Georgia Law but we do have Lawyers on here that might be able to quote it.
What I perceived was that he shot while the suspect was facing a human being with the gun in a threatening fashion and Self defense is justifiable at that point.
Now once the justification is warranted, at what point the Law says the SD shooter was to stop is sometimes grey.
Just because the guy turned to run, doesn't mean the threat was over and I personally think it would be hard to prove the threat was over in a court of law.
