They kept getting up when he told them to stay down so he had to hit them a few more times in order achieve submission. If he wanted to he could have killed them but he controlled himself.

He did exactly what needed to be done. Give this man a medal.
Is there another video that we haven't seen? The one I saw showed the original attackers on the floor behind the counter, out of sight.
