And to jump completely off topic, when are we going to realize that there was no security failure at the checkpoint on 9/11? The criminals did nothing illegal up until the moment they hijacked the aircraft.* The box cutters were legal to bring on board and were possibly detected in the x-ray of the carry on luggage.
Why, exactly, do we need TSA when there was no problem in the first place? I guess for the same reason toothpaste is illegal when in poses no danger to the flight.
*It's possible they did illegal stuff like over stay their visa or speed to the airport, but 9/11 was not a screening problem.
