I will post analytically about this when I get a moment, but the General Counsel to the CIA, Stephen Preston, delivered an address today at Harvard Law School on the CIA and the Rule of Law.
Lawfare has posted up the full text, but here is a bit of the introduction. I'll come back to comment for real later, but I want to commend Mr. Preston for having looking for ways in which the senior lawyer(s) of the Agency can say something publicly about their work and the legal framework in which they approach things that are sometimes genuinely secret, sometimes plausibly, implausibly or, as I mischievously remarked in a panel last week, "preposterously plausible."
There are reasons for these gradations - particularly, consent for US operations in a country might well be secret and subject to some level of deniability. But they make it difficult for CIA officials and lawyers even to acknowledge the topics in the abstract. There will be lots of disagreement, no doubt, about what can or should be made public by executive branch lawyers, whether through DOJ, CIA, DOD, DOS, or other agencies - but I would like to commend Mr. Preston for seeking to find ways to address these issues, to the extent that he and others in the executive believe they can or should do so publicly.
