The University of California Berkeley, the self proclaimed home of the Free Speech Movement of the 1960s, has proven itself to be anything but that of late. In February 2017, riots broke out to prevent Milo Yiannopoulos from speaking on campus. Conservative campus activist David Horowitz was forced to cancel in early April 2017 because of strictures placed upon organizers for security.
Ann Coulter was slated to speak on April 27th but UC Berkeley Administration officials cancelled Ann Coulter from speaking. The Young Americas Foundation and Berkeley College Republicans filed suit against the University of California Berkeley and University of California system Chancellor Janet Napolitano detailing how the academicians created de facto limitations on free speech and engaged in viewpoint discrimination.
Nonetheless, organizers supposedly withdrew their invitation for Ann Coulter to speak. There is some controversy over that because the organizers claim that the University never gave them the room or hall for the event. However, the polemicist used that premise to cancel her appearance on campus despite Ms. Coulter's prior protestations. Sadly, the heckler's veto triumphed, even though Coulter and the College Republicans was solidly within Free Speech rights.
Even though Ann Coulter was a no-show at Berkeley, riot police still had to prepare for violence from both antifa elements and clashing counter-protesters.
