Could you imagine legal students, people being trained in adversarial debate, thinking the best approach is to shout someone down?
I think the Judge is a piece of shit. I don’t like him as a human being. However, “ignoring” is precisely what should have happened here.
Also, if you watch the video the entire thing was staged - the students shut up on command - to get that lady dean up on stage where she could present her prepared speech about how valorous it was for her and them to shut him up. Pure hypocrisy.
