This is obviously a commonality among many countries, especially attempts to facilitate border crossing and make it easier. One of the problems with those attempts to facilitate and make life easier is that it comes with the provision of a massive amount of information, which then gets widely shared. The vision is, let's make it easier for people to travel across borders, but the price of doing so becomes passenger lists, other sorts of information, or biometric data, as you provide in a NEXUS context.
There has been a large price, it seems to me, in terms of some of the things that people have to surrender as part of that. Perhaps other colleagues on the panel have their own experience or knowledge, but I think we are seeing many countries grapple with some of the same kinds of questions.
One thing, though, that distinguishes our country from pretty much all others, save, I suppose, Mexico, is that our border is with the United States, or at least our most commonly traversed border is with the United States. Given what we are seeing take place in the United States, it really is unavoidable to begin to look at those issues, especially in the way that we have tried to facilitate some of those border crossings by saying, let's do pre-clearance, and, in fact, let's facilitate as much pre-clearance as possible.
