Actually, you're asking why has the law not been changed, and I'm not sure you're asking the right person. What I can say as an official is that the system we have has so far, subject to what the Supreme Court will tell us soon, been found to be fair, constitutional, not perfect, exceptional, and there's no question about that, but we're dealing with a very difficult dilemma of how to deal with individuals who are a security threat, who in five out of six cases, again, have been determined by the Federal Court to be a security threat and who should be removed from Canada--because that's the normal policy of the state, to remove persons who are security threats.
The immigration tool is a legitimate tool. The process is obviously the subject of very legitimate debate--but if I may take more than fifty seconds--I would be inclined to follow with why immigration law versus criminal law, which would address the premise of the member's question, which I think is important to answer, with your permission.
