I'll just try to answer who we're sharing it with. If you want to keep these sorts of individuals off a plane, you have to tell the people who control who gets on a plane who they are. That's how you do it. Otherwise you can't do it. You have to get the right security information, the right people, at the right time to be effective; otherwise you've lost the game. In terrorism, there are no second chances. It's a preventive type of measure.
We do share it with air carriers. Our regulation specifies that they are not permitted to share the information with anyone else. In addition to that, we're having them sign a memorandum of understanding that goes into greater detail about protecting the privacy and security of the list and that meets both privacy and security concerns. That sharing is necessary, balanced against the concern for public safety and security of person that is a basic human right. We are sharing, but with that aim in mind, and we're putting stringent conditions on any disclosure of that information any direction beyond that.
