Newsweek has put the "secret torture memo" online here.

The March 6, 2003 draft memo from the Defense Department, which was obtained in part by NEWSWEEK, is titled a “WORKING GROUP REPORT ON DETAINEE INTERROGATIONS IN THE GLOBAL WAR ON TERRORISM” and explores numerous legal defenses for acts that might be construed as torture. (Click here to read the memo). It was first disclosed by The Wall Street Journal on Monday. Along with several other memos to come out of the Justice Department’s Office of Legal Counsel—two them previously disclosed by NEWSWEEK—the 56-page DoD memo is believed to form the main basis for legal arguments justifying intense interrogation methods used at Guantanamo Bay. Some of those methods were later believed to be adopted for use at Abu Ghraib prison in Iraq.
