In the three tumultuous weeks since protests broke out at U.S. universities, police have descended on dozens of campuses to sweep up students in mass arrests, adhering to an approach many criminologists have found to be outdated and counterproductive. New York police arrested nearly 300 people at Columbia University and City College of New York on April 30 during protests over the war in Gaza, setting off flash bangs to stun and disorient demonstrators. But an early examination of the approach to campus protests suggests police, in many cases, have yet to shed outdated ways of handling large demonstrations, they said.
