Reason's favorite security expert Bruce Schneier absolutely destroys the Transportation Security Administration's Kip Hawley in a debate about post-9/11 airline security changes at The Economist.

Schneier's wrap up:

Return airport security checkpoints to pre-9/11 levels. Get rid of everything that isn't needed to protect against random amateur terrorists and won't work against professional al-Qaeda plots. Take the savings thus earned and invest them in investigation, intelligence, and emergency response: security outside the airport, security that does not require us to play guessing games about plots. Recognise that 100% safety is impossible, and also that terrorism is not an "existential threat" to our way of life. Respond to terrorism not with fear but with indomitability. Refuse to be terrorized.
