Well, again, this is purely speculative on my part, without having the details, but we have various intelligence systems that would provide lookouts to our front-line border officers for specific people for specific reasons. It may have been--may, I would stress--that one or more of the people on the buses may have been the subject of a lookout. There are myriad reasons why this may have happened. I'm very hesitant to speculate on what the reasons were, but, as I say, the fact that so many people would have been detained en masse is something I'll certainly look in to.
