What's really ridiculous is the US widow asking for $125 million for compensation. 

What Khadr did on the battlefield is a separate issue from the torture he suffered while the Canadian government sat by and did nothing.  I don't like Khadr, but he confessed to a crime and spent the time in GITMO for it.  A drunk, well educated adult killed six people (three generations worth) in Toronto, and only got eight years in prison.
