It's a specific number and it enables the persons to be freed if in fact their identity is proven. Or they can always apply to the public safety minister to be released within the year. So that can happen.
I don't see the constitutional problem that you are raising there. I think most people would agree we would be foolish to let everybody come in as a refugee, given that maybe only 0.1% of them pose a security risk, but that's enough to say to many Canadians, “I'm sorry, we can't have the risk of someone like that settling in our neighbourhood.” Our compassion, which is invested through our government into a very vibrant refugee system, will be cut off. We can't afford that.
