You'd think the perp just stole the deputy's gun and not a spare clip. I wonder how many rounds he's already expended. He should be running out of ammo pretty soon.
Witness on MSNBC described hearing five shots.
Unless the goblin took an extra magazine, the most rounds He probably had in the gun was 17. So He might well be out of rounds by now.
There are lots of armed citizens in Atlanta/Fulton County. Maybe He will run into one of those folks, who will end the problem for everyone.
