Well, many people have called for that, but the government replies that it's the nature of national security not to tell people if they're on the no-fly list. I believe even if you're stopped in the airport, as my colleague just said, you will not be told exactly why you are stopped or why you can't take the plane. From what I understand from national security experts, to tell the person who has been stopped why he or she is being stopped is to reveal how much the government does or doesn't know about what they may or may not be doing. So it's all very secretive.
