Documents discovered in Libya suggest a close relationship between the Libyan government and the CIA. The New York Times described it this way on September 3:
TRIPOLI, Libya — Documents found at the abandoned office of Libya's former spymaster appear to provide new details of the close relations the Central Intelligence Agency shared with the Libyan intelligence service — most notably suggesting that the Americans sent terrorism suspects at least eight times for questioning in Libya despite that country's reputation for torture.
And then today (9/6/11) the Times put it this way:
The cooperation appeared to be far greater with the American intelligence agency, which sent terrorism suspects to Libya for questioning at least eight times, despite the country's reputation for torture. Britain sent at least one suspect, according to the documents.
As Glenn Greenwald pointed out on Twitter (in fewer characters), the whole point of rendition was to send prisoners to countries the United States knew would treat them a certain way. It wasn't a series of accidents. In other words, the CIA used Libya not despite its reputation for torture, but because of it.
