I don't usually agree with Lee Ann's political opinions but in this case I think she is right. As Zeca Brown said in his post many Governments around the world have been using the fear that they have whipped up since 9/11 to introduce repressive laws and restrictions they wouldn't have got away with before the twin towers event. It's not just full body scanners but the Patriot Act in the USA and the increase of the time that the UK police can hold people in custody without filing charges. As a Brit I always thought (and still think) that Habeaus Corpus should be sacrosanct. When I was young you could only be held for 24 hours without charges being brought but now they can hold you for weeks without even letting on why!
The point is, there is a species of bureaucrat in the Governments of all countries that are always looking for ways to restrict the freedoms of their citizens.
To be GOVERNED is to be watched, inspected, spied upon, directed, law-driven, numbered, regulated, enrolled, indoctrinated, preached at, controlled, checked, estimated, valued, censured, commanded, by creatures who have neither the right nor the wisdom nor the virtue to do so. To be GOVERNED is to be at every operation, at every transaction noted, registered, counted, taxed, stamped, measured, numbered, assessed, licensed, authorized, admonished, prevented, forbidden, reformed, corrected, punished. It is, under pretext of public utility, and in the name of the general interest, to be place under contribution, drilled, fleeced, exploited, monopolized, extorted from, squeezed, hoaxed, robbed; then, at the slightest resistance, the first word of complaint, to be repressed, fined, vilified, harassed, hunted down, abused, clubbed, disarmed, bound, choked, imprisoned, judged, condemned, shot, deported, sacrificed, sold, betrayed; and to crown all, mocked, ridiculed, derided, outraged, dishonored. That is government; that is its justice; that is its morality.
—P.-J. Proudhon, "What Is Government?", General Idea of the Revolution in the Nineteenth Century, translated by John Beverly Robinson (London: Freedom Press, 1923), pp. 293-294.
If Proudhon had been writing today he probably would have added that to be governed is to allow some petty jobs - worth to grab your balls!
That said, despite what I think I would still go through the full body scanners if they introduced them in Britain. I live and work in Indonesia, refusing to go through the scanners would make it very difficult for me when I want to visit friends and family.
