If I may, I just have a follow-up question. One of the challenges we're seeing right now and I think most MPs are probably hearing about from constituents is the background checks. What they're asking these people to provide is their name, their sex, and their date of birth, which is basically what we're talking about here. I think the reason they're asking for the date of birth is that people can change their names; it's tougher to change your date of birth. We're actually finding people who are caught up in that, in the sense that they have the same birth date and same year as a felon. So it creates a challenge.
Is that not similar to what we're seeing with the request from the Americans to fly over their airspace? Is that not just a very simple way of identifying people, or at least shredding the unnecessary follow-ups that take place? If you can match a birth date and the year, that may well be worth exploring a little further to identify who the person really is. Is that not what they're asking for in a similar vein?
