Tell that to Columbia University

On April 17, 2024, Columbia students established the Gaza Solidarity Encampment on the East Butler Lawn. The next day, Columbia President Minouche Shafik called in the New York City Police Department (NYPD) to arrest them en masse[8][9]—the first time Columbia allowed police to suppress campus protests since the 1968 demonstrations against the Vietnam War.[10] Shortly after the mass arrest and dismantling of the initial camp, other students autonomously occupied the adjacent lawn and established another encampment there, holding it for several days as students negotiated with the administration.[11] The Columbia encampments encouraged other actions at multiple universities and led to the proliferation of Palestine solidarity encampments at over 180 universities around the world.[12]
