When should uni protests be shut down?

At Columbia University in the heart of New York City late one evening this week riot police stormed a university hall.  They entered via a window to arrest students who’d for weeks been camping out at the campus to protest against the war in Gaza.  Now, the pro-Palestinian movement that’s seen more than a thousand students arrested across the US has landed here.  Today, we look at the encampments popping up on campuses across the country and ask how will university leaders allow freedom of speech while ensuring Jewish students and staff feel safe?  Featured:  Dr Tim Dean, senior philosopher at the Ethics Centre
