I’m glad this was not twice in the chest and once in the head. That could sound like something more than shooting to stop the threat.
I’m not convinced there were any deliberate shots. All of the shots caught on camera we’re in the middle of a struggle for control of the gun. He was barely hanging on to the shotgun while the thug beat him in the head and grabbed at the gun.
He wasn’t technically shot in that sense. He was wrestling for a gun, and he was handling the barrel end of that gun, and several times he pulled it and it went off, hitting him in the hand, and then the chest.
As soon as he let go of the gun, the man holding the gun pointed it directly at the ground, even though the man pushed him again, and then started running away. It was pretty clear at that point that the son was not trying to kill him, if he was, he would have been raising his gun to shoot the guy again, not letting him run away.
