I just have one question as a follow-up.
I'm intrigued by the way you've expressed it—I appreciate the sentiment and the commitment to the values—by the way you suggest we can use the evidence, but once we have to detain a person or limit liberties, we have to then have evidence of our own that we can produce.
Using that logic, what has been troubling me is that we would not be able to detain anyone based on information that we get from abroad unless we have evidence of any criminal activity here. That is the quandary governments find themselves in. I'm not defending anything here, but if you were sitting around the cabinet table, you could not detain an individual, could not deport an individual under the security certificate, because you don't have the evidence of commission of crime in Canada—which you could gather, I agree with you; we should be able to do that.
What do you do in those situations if you find the evidence you have obtained from elsewhere to be reliable but you can't produce it?
