The signs at the Logan Airport security checkpoints still say that the airlines are in charge of the screening personnel, and that if you have a complaint you should contact the airline. I am told by the airport's security office that this is untrue. They've added lots of signage since 9/11; leaving this untruth so clearly and systematically posted must be deliberate.
When I inquired about the discrepancy, the soldier guarding the X-ray machine asked me why it mattered who was in charge. He also addressed me by my first name (which he knew from my ticket and identification papers -- oops, I mean my photo ID).
The next time a soldier in the airport orders you to produce your papers, try to think of a movie where the question, "Your papers, please?" is asked by the good guys.
