Okay.
On another subject, we understand you're beginning a pilot program of behavioural screening at the Vancouver airport. We also understand that in the United States they had a similar program, which they extended nationally, and they were criticized by the Government Accountability Office for not truly evaluating the results of the pilot. Can you explain how your pilot will work and how you will avoid those problems they had in the U.S?
Also, one point that's important to me is that if people are sort of wandering around the airport locating suspicious-looking people, what criteria do they have and what guarantees are there that this won't degenerate into some sort of racial or religious profiling?
