Okay.
Finally, we'll return to this particular subject, but I have other concerns. I've heard from officers that perhaps individuals flagged by INTERPOL could get on an airplane, be on a list—noted at Heathrow—arrive in Canada, and since many people have dual or triple passports these days, all they have to do is switch their passports and they can get through primary without being flagged. Could you answer that?
Also, something that I have found perplexing, and it's perhaps really low tech, but it's common sense. Virtually every country in the world has separate lines for the citizens of their countries, as they enter primary inspection, and separate lines for non-citizens. In this post-9/11 world, why wouldn't we have done something as simple as that?
