Body scanners are nothing new, I first remember joking about them as far back as 1997 when I speculated about how the scientists went about testing them during the R&D phases. The topic has come up periodically over the years depending on various security scares. Most recently, the underwear bomber has brought the technology back to the forefront for identifying threats to safe air travel. As per usual, the argument is that the scanners are too good. Ben Franklin once commented, "he who would trade liberty for some temporary security, deserves neither liberty nor security."

Perhaps in this situation, liberty could be substituted by privacy. Is it worth it? (Just for humor, here's the opinions from the AVN awards, aka porn stars, on privacy and the scanners.)
