This is disheartening. The hand swab was so non-invasive. The scanner is prone to false alarms, takes longer, and requires the humiliating "I'm under arrest" stance. Considering that even Kleenex leads to a frisking, it really is something one must make every effort to avoid.
On one day, I got the "random" on three separate checkpoints. But it was a benign interference, and I joked with the TSA about buying lottery tickets.
I would not have such a good sense of humor if this is the "new" procedure.
One will have to be careful to avoid being in line behind crew members. Even when not on duty, they are exempt from random beeps. So it's almost a guarantee if there are half a dozen or so crew members in the line.
But the TSA varies its "new procedures" quite a bit. Perhaps they'll rethink this one too.
