A story at Truthout reports that a Department of Defense Office of Inspector General investigation into allegations of drugging of detainees, completed almost exactly a year ago, was nevertheless hidden from public knowledge for months. Its results remain hidden, labeled classified. This is especially strange as this document was publicly requested by no less than now-Vice President (then Senator) Joe Biden, along with Senators Carl Levin and Chuck Hagel, after a couple of articles — one by Jeff Stein and one by Joby Warrick at the Washington Post — blew the whistle on dozens of reports of alleged drugging of detainees.
