No more invasive than a pat down. Really?

Privacy groups like The Electronic Privacy Information Center - EPIC have been warning us about these things for a long time and it seems like as much as the TSA would want us to believe otherwise, we were justified in raising the alarm.

In this case a male worker at Heathrow flipped the machine on as an attractive female co-worker walked near the machine. He apparently made some lewd comments and though I haven't been able to find any sources saying what those comments were, I think I can make some general guesses.

The British House of Commons said this of the machines when they were deployed:

"Having witnessed these full-body scanners working at first-hand, we are confident that the privacy concerns that have been expressed in relation to these devices are overstated and that full-body scanners are no more an invasion of privacy than manual "pat-downs" or searches of bags," the committee said.

Oh really? A pat down and a nudie scanner are the same thing? What do you think?
