I feel as though when so people are fighting somebody at some point should try and stop them. Not in this case. Watching the video and listening to the people who surrounded them, they definitely knew the the two women beating the crap out of each other.
They supported the fight and even went as far as to root them on and suggest techniques! At one point you can hear the man in the background yell,"Wrap your legs around her waist!"
Later in the video you can hear the opposing young lady ask,"Why do you have all these parents here with you?!"
The parents are really no better than Kobra Kai Sensai in this instance and most likely deserve to have their ass beat! SMH - Terry J
