"[A]sk yourself, why wasn't this released to the public by the Obama Administration?"

In his classic The Morality of Law, Lon Fuller asked whether a "law" that was never published or made available to the public would really qualify as law in the first place. Given that there is no apparent legal justification for withholding the memo purporting to justify targeted killings on legal grounds--no dangerous national security information, no top-secret codes or anything like that--I think it's telling that the Administration chose not to publish it. If the memo is defensible as a legal document, why would the Administration not proudly and publicly assert its legal position?
