Given that Khadr has never had a fair trial, and that the Americans have made absolutely certain that he never will have one, we don't know what he did or did not do. His family is completely irrelevant; guilt by association is not and never has been part of Canadian law.

I take it that you don't believe in due process, and would prefer to simply jump from accusation to punishment without bothering about all that messy stuff involving examining the evidence.
