I will be sure to be careful about emptying my pockets! ...Most things will probably be in my jacket pockets anyway, and that will just come off to go through the machine by itself.

If I get pulled for extra screening anyway and have to choose between Scylla and Charybdis here, I'm going to take the backscatter -- I don't like the idea at all, but it's way less likely to trigger me. (I can probably just gesture at the rant about security measures making people feel more anxious and uncomfortable here, right?)
