Nothing new in the Vanity Fair article below, but a great reminder of the inconvenience and general worthlessness of most of the "security theater" we see at the airport.
The other aspect not talked about is the self-perpetuation of such a security regime. Who are the experts who will make the decision of what ensures security? The TSA. Who would lose jobs and influence should security measures be ramped back? The TSA. Thus endeth the lesson. #ddtb

Does Airport Security Really Make Us Safer?
Heaps of federal money, endless bureaucracy, and constant travel delays are the most visible by-products of the Transportation Security Administration. Too bad “increased safety” doesn’t fit on that l…

What you said. It’s wasting our tax money and doing nothing useful. The Israelis and the Brits are probably laughing up their sleeves at the TSA protocols.
@Marina – Except to the extent they are compelled to use them for flights going into the States.
That guy was an expert? Ha.
9/11 wouldn’t have happened in Europe, due to the difficulty in getting weapons on board. The bombs of the 70s/80s tended to be smuggled aboard out side of Europe – the ‘Lockerbie bombing’ there lots of evidence it was planted outside the EU (Malta, I think). The US has swung from one extreme to the other.
@LH – 9/11 happened because passengers were cowed by box cutters, given the perceived risk. That perception has significantly changed. Increased airport security hasn’t made hijacking by box cutter that much harder. It has made flying for the 99.99999% of non-terroristic fliers that much harder, though.
