Yes, I am well aware of the Arar case, as most Canadians at this point probably are. The way you described the situation was quite a bit different from what is actually known to have happened. He was actually deported from the US to Syria (where he was born) as an "extraordinary rendition", where he was subsequently tortured and forced to admit to things he knew nothing about. I'm just surprised they let him out. Most people in his situation simply disappear.
