And no matter how high-tech and effective the machines may be, they are still only as good as the humans operating them.
One thing I wonder about the humans- will they go through these scanners before they enter the secure booth from which they observe the people who are being scanned? Otherwise, I would imagine that there will be cell-phone cameras used/abused to take pix of celebrities, or just of exceptionally well-endowed people, or perhaps of those with funny figures, large and small.
It's easy to imagine abuse like this- if Pamela Anderson (sorry, Pam) goes thru the scanner, an accomplice of the person with the cell phone could say, "hey, get this shot". Next stop, National Enquirer!
We looked into the carry-ons, then Richard Reid wore his explosives on his feet.
We took off our shoes, then there was a plot to put explosives in toiletries.
We went to the 3-oz, plastic bag rule for our toiletries, and then this latest creep sewed his explosives into his undies.
Now we are to expose our bodies for strangers to see. Truly, what is next?
(This morning, as I leaned in to turn on the shower, a kernel of corn popped out from where it had been hiding all night- under my left bazoom. I couldn't help wondering if the scanner would have spotted that little kernel...and I think I could conceal something even larger under there!)
