Anti-war activists protested 8/17 at the University of California, Berkeley to call for the firing of a law professor who co-wrote legal memos that critics say were used to justify the torture of suspected terrorists. According to the Associated Press, campus police arrested at least four people who refused to leave the university’s law school building. The demonstrators said John Yoo should be prosecuted for war crimes for his work as a Bush administration attorney from 2001 to 2003, when he helped craft legal theories for waterboarding and other harsh interrogation techniques. Shouting “war criminal,” the protesters confronted Yoo as he entered a lecture hall on the first day of class at UC Berkeley’s Boalt Hall School of Law, where the tenured professor is teaching a civil law course this semester. Yoo, 42, mostly ignored the demonstrators and defended the controversial interrogation techniques, saying they were needed to protect the country from terrorists after the Sept. 11, 2001, attacks..
