Most people who are concerned about their privacy have objected to airport security body scans. There are claims that the scanner is "remotely reviewed" by a person who 'cannot' view the face of the person being scanned. That doesn't make people feel any safer. You could find an earlier British prototype showing the use of a full body scanner. Here is news of installation of such a device at Heathrow. This body scanner looks identical to the newer one.
I see another Slashdot story which shows an anti-hijacking safety bracelet. There was a 1976 patent following the 1972 Munich games by a Singapore Inventor Sai Kheong Kwan and a former Vice-Chancellor of the National University of Singapore. This is literally a handcuff which didn't make it. Governments are taking monitoring for security too serious and are probably not as well prepared in counter-measures. The inconvenience is weighing far too heavily against the advantages."
