On September 14, 2017, Shapiro gave a speech at the invitation of the UC (Berkeley) student organization Berkeley College Republicans where he criticized identity politics.[87][88] The event involved a large police presence which had been promised by Berkeley Chancellor Carol T. Christ in her August letter that supported free speech. Together, the University and the city of Berkeley spent $600,000 on police and security for the event, which transpired with nine arrests but no major incidents.[89][90][91]
