Mora concluded that Yoo’s opinion was “profoundly in error.” He wrote that it “was clearly at variance with applicable law.” When we spoke, he added, “If everything is permissible, and almost nothing is prohibited, it makes a mockery of the law.” A few days after reading Yoo’s opinion, he sent an e-mail to Mary Walker, saying that the document was not only “fundamentally in error” but “dangerous,” because it had the weight of law. When the Office of Legal Counsel issues an opinion on a policy matter, it typically requires the intervention of the Attorney General or the President to reverse it.
