Khadr's sister has never changed her views. There are recent blogs to the effect that if you cannot be a True Muslim you must leave your mosque.
That includes vilifying homosexuality and refusal to integrate into Canadian society. No questioning of belief is permissible. Not to mention her support of terrorism!
In what universe would it be ok for Khadr to associate freely with this woman? 
And with 10 million to donate to one if her favourite "charities"..
Chretien was duped by the father...let us not make a similar mistake.
