Two things struck me as a lawyer reading the recently released Yoo memorandum: First, the poor quality of the reasoning displayed in the memo -- logical gaps that that, if they appeared in a first-year associate's research memorandum on a piece of business litigation, would lead the supervising partner to demand an immediate rethink and rewrite. And second, the absurd way in which citations were used to buttress an assertion, where Mr. Yoo's prior memoranda were given equal weight with opinions of the Supreme Court.
