In 2002, Canadian citizen Maher Arar was detained at JFK Airport during a layover, rendered to Syria by the CIA, and tortured for nearly a year in a coffin-sized cell. A Canadian commission later confirmed he was completely innocent -- the RCMP had shared faulty intelligence with the US. Canada paid Arar $10.5 million in compensation. The US government never apologized and kept him on the no-fly list until 2009.
