The events earlier this month in Charlottesville once again highlighted the tension between free speech and safety. This tension is particularly acute on college campuses where beyond simply protecting First Amendment rights, schools aim to expose students to new ideas and to develop critical thinking skills. Erwin Chemerinsky, the dean of the UC Berkeley Law School, examines the polarization of expression and protection in his new book,”Free Speech on Campus,” which he co-wrote with UC Irvine Chancellor Howard Gillman. Chemerinsky joins us to talk about how schools can be inclusive and nondiscriminatory, yet still encourage expression and exploration of ideas. We’ll also hear his thoughts on the far right-wing rally and counterprotests planned in the Bay Area this weekend.
