The shooter was the same in both instances. The extra shots are of unknown origin. The head shot, that I described second, was the first instance.

The rioters were dumb enough to corner a man with a gun. One did the silly "come on, shoot me" thing and got shot in the head. The rioters then chased the shooter a very long ways, until he fell to the ground.

The guy who got shot in the biceps was attempting to use a pistol to execute the guy on the ground. I couldn't make it out, but the biceps loser had a cell phone in his left hand and a pistol in his right hand. He held both hands up as if to surrender, using that to get closer to the guy on the ground. At this point the guy on the ground had killed 2 people, but he held back. The biceps loser suddenly brought his hands down to fire the pistol. It was a clear attempt to execute the guy on the ground, who then shot off the biceps that was on the arm holding the pistol.

The shooter showed lots of restraint. In numerous cases, he pointed his rifle at potential attackers, but he didn't shoot if they backed off. Legally, he's going to be fine, but I wouldn't be surprised if a politically-motivated trial happens.

His score is 4 rioters shot, 3 of whom died. The biceps loser, who tried to perform an execution, will almost certainly live. The arm might be saved, but that is uncertain.

My overall impression is that it looked like a zombie movie. WTF. The rioters just kept coming, seemingly unaware that in real life you can actually get mangled or killed. The rioters are insane. It's interesting that they scream "medic" when injured. They don't scream "police" or "call 911" or "help" or anything normal. It's like they imagine themselves to be soldiers or in a video game.
