John Yoo's greatest hits, courtesy of Wikipedia:

Yoo wrote a legal opinion memo in response to the General Counsel of the Department of Defense, in which he concluded that torture not allowed by federal law could be used by interrogators in overseas areas.

"Because the United States is at war with Al Qaeda, the President possesses the constitutional authority as Commander-in-Chief to engage in warrantless surveillance of enemy activity."

Yoo suggested that since the primary task of the President during a time of war is protecting U.S. citizens, the President has inherent authority to subordinate independent government agencies, and plenary power to use force abroad.

He seems nice.
