IND A concourse on Monday was doing the normal random scanner/metal detector as always. LGA D terminal didn't have any scanners that I saw, just metal detectors. I travel for work every week. I like the metal detector choice just because it's faster, especially since I don't have to remove my belt. I'd do a scanner before a patdown for the same reason. I have no problem with scanners, just don't like the extra time they take (see "Up in the Air" with George Clooney). I don't see scanners as invading my privacy. I'm comfortable exchanging some stranger seeing my image on a scanner to fly. Now, if someone wanted to scan me to drive my car, that would be a different matter. To me it's a reasonable precaution and I'm willing to accept that.

Amygdala..Amidala? Crap, now I know why I was so scared of Lucas ruining the franchise and the fragile memories of my youth!

Great, now I'll have to add Lipitor(tm) to my diesel tank so my car's fuel line doesn't get plaque build-up.

It's DR. Fusion! I didn't spend six years in Fusion Medical School to be called "mister," thank you very much.

I could swear that I saw this concept in a movie at one point in time. Any reason why someone didn't think of this approach sooner? What are the drawbacks?
