Lashing out at a teacher ... I think there were other ways to tell this gentleman that what he did was wrong. "

A video of a student's parent at the origin of the act?

A father of a student whose daughter did not attend class nevertheless filed a complaint, and above all published a video on the Internet calling for the teacher to be denounced.

He even posted the professor's name online.
