Jack Balkin on John Yoo
He writes:
Balkinization: My own conclusion is that Yoo and Bybee did violate their professional obligations to the President as constitutional actor, and to the country as a whole. The reason is a combination of their outrageous theory of presidential dictatorship and their all too eager assistance in what appears to be a conspiracy to commit war crimes. But I do not pretend that the question is at all an easy one.
