Anti-war activists are protesting at the University of California, Berkeley to demand the removal of a law professor who used to craft legal theories for the Bush administration on waterboarding and other harsh interrogation techniques.

Monday is the first day of classes at UC Berkeley's School of Law. The target of the protest there is John Yoo, who worked for President Bush's Office of Legal Counsel in 2001-03. The demonstators want Yoo to be prosecuted for war crimes.

A recent Justice Department investigation into his work for the Bush administration found that Yoo and his former colleagues showed "poor judgment" but did not commit professional misconduct.
