Airport Security as Theatre

Yesterday's Greenpeace Heathrow protesters reminded us that governments are working hard at the magician's trick of redirection: "Everyone pay careful attention to the long lines, uniformed attendants and electronic technology at the passenger-screening station. Pay no attention to the unlocked/unmonitored doors and gates that provide direct access to the aircraft." Also see Bruce Schneier on this topic. Bruce also spotted this, which should really give you pause.
