Thank you.
The way this would work is that when someone arrives at the airport, they're required to bring ID. The purpose of that ID is to distinguish them from people who might be on the list, so on the fairly narrow chance that your name would match someone on the list...because the list itself has been constructed against very stringent guidelines, and in a very focused way; we have focused ourselves on creating this, we have learned lessons from around the world in doing that. You produce your ID, you distinguish yourself from that person on the list, and you get on the flight. There is no problem with that.
The situation you're talking about is the rather unlikely situation of one of these individuals whose name, gender, and date of birth and other information confirms that they are actually on the list. Then we're into another dimension, but that's a very different dimension, and that's something that I think would concern everyone on the flight and everyone living in that city, given the sort of incident we're talking about.
