This whole thread goes back to one thing, and that is yes, you should have to show ID to get onto a plane. The whole issue was that a man refused to show the TSA his ID. The security check point is the ONLY place that you show your ID when you get on a plane. You can print your boarding passes online, no ID required. You go to security and show your ID and boarding pass to show that the same person on the boarding pass is the person trying to get on the plane. You then proceed to your terminal where you board the plane by showing only your boarding pass and no ID. So, your photo ID is the only way they have of proving you are who you say you are (and yes, I get that they can be faked). I guess if you don't like that, we can always implant a chip in each and every child at birth. That way, there will be no question who is getting on.
