A series of blog posts by a former OLC lawyer, Marty Lederman, discussing the difference between the DOJ's memo on torture from August 2002 and the memo on torture from December 30, 2004 (ACLU-RDI 3547).  The posts conclude that the Bush administration must have determined that the only constraint on CIA interrogation was the anti-torture statute - in other words, that the administration had concluded that the prohibitions on cruel, inhuman, and degrading treatment did not apply to the CIA.
