] Your readers already know about my opposition to useless
] airport security crap. I'm suing John Ashcroft, two
] airlines, and various other agencies over making people
] show IDs to fly -- an intrusive measure that provides no
] security. (See http://freetotravel.org). But I would be
] hard pressed to come up with a security measure more
] useless and intrusive than turning a plane around because
] of a political button on someone's lapel.
