The other day I traveled by airplane, and I was pulled out of line for special consideration.
Actually, there wasn’t all that much of a line; it was Saturday night, and the airport was relatively quiet. But I was pulled out of whatever line did exist by a nice young uniformed man who asked me to hold out my hands to be swabbed. He ran a sort of Q=tip moistened with something or other over them and then ran that in front of a machine that read out a bunch of figures. And then he waved me on my way, after explaining (when I asked him) that he’d checked me for explosive residue.
Good thing I hadn’t fired any cap guns recently.
I can only hope they’re profiling, too, on the QT.
