A report from October 2008, when the naked body scanners were first being
introduced at Melbourne Airport in Australia, detailed how the X-ray
backscatter devices don't work properly unless the genitals of people going
through them are visible.

"It will show the private parts of people, but what we've decided is that
we're not going to blur those out, because it severely limits the detection
capabilities," said Office of Transport Security manager Cheryl Johnson.

"It is possible to see genitals and breasts while they're going through the
machine," she admitted.

Any questions?
