I understand completely where you are coming from. And I assume some people did run for help. Good for them. It's the ones that did nothing and just stood there watching, some with small children even...that bother me. If I was there when my children were small and this happened, I would like to believe that I would have first gotten them to safety in case things got out of hand before even thinking of getting involved. I definitely would not have just stood by and watched though either way. That is just crazy imo. If I was there without my kids, I would have looked for an opportunity to take the guys back (since there were already people calmly speaking to him about cooling down), probably during one of the multiple times he was attacking someone else, and then attempted to submit him which is exactly what it looks like the one guy did. He actually went down pretty quick once the guy got him in the rear naked. And actually, it's hard to tell from the video (especially on my phone) how deep the guy sunk the choke. It could have been that he was just restricting the bully's breathing...which is also effective but also a lot more dangerous. I would not have gotten up in his face and started screaming at him, which thankfully no one did except for the ones that were apparently part of his family. Just my opinion.
