Oh, I think it's safe to assume that I do.
She might have done that-
Done what? You mean the DJ? If so, there is no MIGHT about it. It is on video.
there are techniques to stop ringleaders in a riot situation.
You mean like ask them multiple times to leave the area, then if they don't, arrest them ?
you try to identify the ringleaders who ARE escalating things, and you remove them
Which is exactly what the officer was doing.
If you remove the ringleaders, the riot usually dies.
The officer did. He subdued her and placed her under arrest. The 'riot' quickly subsided.
Crowd mentality is a very complex thing.
Actually it's not. It's a very simple and mindless thing. So simple that (as you said) removing the ringleader usually brings things to a halt.
You are clearly not seeing this the same way anyone with a brain does.
The officer was OUT OF CONTROL and HE WAS ESCALATING the situation, every place he went.
He was the only officer running back and forth screaming and swearing. Why I would accept the argument that he did nothing UNLAWFUL, I can see and hear from the video the screams and panic every place he runs.
Am I somehow not making this clear? He ESCALATED the situation through his actions. He clearly did not calm things down in any way.
He ran over to a group of kids and started attacking a teenage girl. This incited the group around her to try to move in to protect her. If I was there I would have start yelling at the officer to calm down.
