Not that long ago, I wrote about torturing suspected terrorists, and asked "What if they're not guilty?"  Now today, there is news of a Canadian citizen who was added to a terrorist watch list, then sent to Syria as part of a terrorist rendition program, and tortured... for 10 months. Oh yeah... he was completely and totally innocent:

Canadian intelligence officials passed false warnings and bad information to American agents about a Muslim Canadian citizen, after which U.S. authorities secretly whisked him to Syria, where he was tortured, a judicial report found Monday.
...
The inquiry, which focused on the Canadian intelligence services, found that agents who were under pressure to find terrorists after the attacks of Sept. 11, 2001, falsely labeled an Ottawa computer consultant, Maher Arar, as a dangerous radical. They asked U.S. authorities to put him and his wife, a university economist, on the al-Qaeda "watchlist," without justification, the report said.
...
Arar was also listed as "an Islamic extremist individual" who was in the Washington area on Sept. 11. The report concluded that he had no involvement in Islamic extremism and was on business in San Diego that day, said the head of the inquiry commission, Ontario Justice Dennis O'Connor.

Arar, now 36, was detained by U.S. authorities as he changed planes in New York on Sept. 26, 2002. He was held for questioning for 12 days, then flown by jet to Jordan and driven to Syria. He was beaten, forced to confess to having trained in Afghanistan -- where he never has been -- and then kept in a coffin-size dungeon for 10 months before he was released, the Canadian inquiry commission found.

What do you say to this man?  No trial.  No opportunity to defend himself.  No chance to stand before a judge and say, "I wasn't even in the same city they say I was in."  Just torture... for 10 months.

Casualty of war?  Acceptable loss?  Tragic mistake?  How do you justify this if you believe that torturing suspected terrorists is necessary in the War on Terror?
