I think there are two answers to that question.
Number one, yes, how you're treated in Guantánamo and ultimately the question of whether or not you leave, the last five years have shown, is a function of where you're from and the willingness of your home country to act to protect your rights. Obviously the story of Guantánamo Bay over the last five years is one of a continuous effort by the political branches to frustrate the ability of the courts to review what's been going on and to enforce the law. So that has certainly created the situation in which, for rights to be protected, it requires the intervention of a foreign government. There's no question that Canada has not been active, certainly in protecting Omar's rights as a child soldier, over the last five years.
Why has the U.S. government treated him differently? I think—to come back to the theme we talked about a moment ago, punishment for the sins of others—there's very little question that the U.S. government early on, not so much because of who Omar Khadr was or what he did but because of who he was related to, saw him as a potentially rich source of intelligence and information about his father and his family and their connections and their contacts. Apparently a conscious decision was made to treat him as an adult and subject him to the interrogation regime of an adult so that information could be extracted from him.
