A skeptical University of Toronto professor who secretly infiltrated the anti-Israel encampment at the school’s downtown campus says many are not actually students and should be forced to remove the barriers blocking people from the area.

“I completely support … the student’s right to protest, whether I agree or disagree, but … that right does not include preventing students from entering common spaces unless they agree with you, and it doesn’t include refusing to make way so that our students can celebrate their convocation on that same common space,” Kevin A. Bryan, an economist and associate professor at the university’s business school, told National Post in an email. “This goes double for the portion of protesters who are not even affiliated with the university.”
