Sky Harbor International Airport here will test a new federal screening system that takes X-rays of passenger's bodies to detect concealed explosives and other weapons...The technology already is being used in prisons and by drug enforcement agents, and has been tested at London's Heathrow Airport..
I can think of all kinds of other places these would work once we get everybody conditioned to this. Hey, if it makes us safer, why not? Besides, what have you got to hide?
