Yeah, but Khadr is a Muslim, so for a lot of posters, I suspect rational thought goes out the window.  However, you are quite correct --it seems very, very unlikely he ever did throw a grenade at anyone.  And yes, he certainly was a child and yes, Canada -- the good guys -- didn't follow its own laws.  One of the things that keeps us as the "good guys" -- and we are -- is that we should follow the rule of law even when it hurts.
