The Terror Presidency: Law and Judgment Inside the Bush Administration (Hardcover)
by Jack L. Goldsmith (Author)
http://www.amazon.com/Terror-Presidency-Judgment-Inside-Administration/dp/0393065502
His book is classic CYA over why he couldn't sign off on Yoo's worse excesses but he clearly articulates the view that "The Law" is a weapon that is wielded by the bad guys. It's quite revealing to realize that these people actually regard the will of the electorate as expessed in acts of Congress as something to be fought rather than the whole edifice they're supposed to be defending.
It's just a totally different way of thinking and if you don't understand it as an outsider than very little else that goes on in DC makes any sense whatsoever.
