This debate is going to catch fire soon enough...particularly since the latest foiled attack was attempted by a man who smuggled the explosives on board in his underpants.
We have the body-scan technology available now that would represent a new leap in security, but the machines can easily become a symbol in upcoming political discourse for all the ways average people feel government is encroaching on their privacy.
There's an understandable queasiness about having one's privates exposed to a stranger, which is what would be necessary for the scanners to be truly effective. If any areas have to be fuzzed out in a bow to modesty, you might as well junk the whole shebang.
Also, there'll be tabloid outlets waving big paydays in the faces of TSA employees bold enough to spirit the video recording of some celeb's body scan out of the airport, the way they stake out hospital employees now. There will have to be strong penalties in place to prevent that.
Personally, I view it like a visit to the doctor to get a prostate exam. To you, it's a mortifying ordeal. To him, it's like checking the oil, he's done so many of them.
Privacy vs. security is a debate we ought to have...but let's not forget that it's better to be embarrassed than dead.
And there's always the train.
