Maybe he behaves the way he does because there are no consequences? Like if he watches a video and screams at you to be silent, maybe snatch his device away? And then if he screams at you you all scream back at him. And if he gets violent trying to get his device back you get violent back (but only as much as needed to counteract his aggression).

But you probably want to plan this out with the other people in the group.

Don't attempt to steal someone's property, and then fight them if they try to take it back, nothing good can come of that.

I didn't mean to steal it, more take it away for the duration of the meeting, as a teacher would.

Even with a teacher doing it, it's extremely murky.

Don't snatch people's stuff, even temporarily, you will catch a fist, and as far as I'm concerned, justifiably so.

I bet you punched a lot of teachers mr tough guy hahahaha
