I would just like to correct what you said, to the extent that you said that they had been released. They were released from the Guantanamo Bay prison, but they were repatriated to their countries. As I just said, some were found guilty, others were brought to court, others were released, according to each individual case. Repatriating a citizen to his country of origin does not leave him free to break the law. As far as Canada is concerned, the Anti-Terrorism Act could be applied to Mr. Khadr.
