From a 2005 debate between John Yoo and Doug Cassell:
Cassel: If the president deems that he’s got to torture somebody, including by crushing the testicles of the person’s child, there is no law that can stop him?
Yoo: No treaty
Cassel: Also no law by Congress — that is what you wrote in the August 2002 memo…
Yoo: I think it depends on why the President thinks he needs to do that.
No matter how cynical I get, I can’t keep up.
