My biggest issue from the start was the socialization of "three bystanders took part simultaneously in kicking and punching the pit bull to get it to release," which failed, predictably, and I didn't want anyone to think that that was a good thing to try in the first place.
I don't know what would have been, so to speak, appropriate and would have been effective. The one thing I knew to try was to do the wheelbarrow and that did nothing at leas in attitude of the pit bull. I was totally focused on my not being excessively injured or letting the other dog be torn apart and didn't organize anyone else's interaction, like "I'll hold the legs and you kick it."
If anything it was the opposite of bystander syndrome where everyone thinks someone else will do whatever is needed. Everyone there was doing whatever they could with the tools and knowledge or lack of knowledge that they had.
