Law professor John Yoo returned to classes at UC Berkeley yesterday, and the loons came out.

Anti-war activists protested Monday 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.

Campus police arrested at least four people who refused to leave the university's law school building.

The demonstrators said John Yoo should be dismissed, disbarred and 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.

“Helped craft legal theories for” is journalese for “analyzed the state of the law and put strict limits on the use of.”

The sad thing is that these barking moonbats may get their wish and the Obama administration may seek to criminalize policy differences for the first time in U.S. history.

P.S. Of course, these “disruptors” probably aren’t “astroturfed,” “evil-mongers” but we should probably check with Nancy Pelosi.
