Yoo reminds me of one of those scientists that created the atomic bomb. They were so intrigued by the project they couldn't forsee the effects it would have on humanity for generations.
Yoo was so fascinated by the challenge of finding the legal protection for the White House that the consequences were secondary. I think he was quite proud of himself for being so clever.
Now he's in front of Congress wondering why he's being sent to the princinpal's office for writing an A+ paper.
