On a similar note to the previous post, but a little more clearcut, here's a NY Times story about a Canadian software engineer who, on false information provided by the Mounties, was detained by the CIA as he changed planes in New York, handed over to the Syrians and tortured. The most damning chunk actually comes from a US official:
"American officials have not discussed the case publicly. But in an interview last year, a former official said on condition of anonymity that the decision to send Mr. Arar to Syria had been based chiefly on the desire to get more information about him and the threat he might pose. The official said Canada did not intend to hold him if he returned home."
