EHD swabs and "false" detections
Today I observed a practice by a two-striper TSA supervisor that partially suprised me, and partially confirmed some suspicions.
Saw the supervisor pulling ETD swabs out of the container and fanning them (like one would do with a ream of paper prior to putting the paper in a printer so that the paper is pulled without jamming), and then putting them back into the container. I assume she did this to make it easier for the TSOs to pull a single swab from the container.
What made me notice this behavior? She did it with her bare hands. No gloves.
So much for "avoiding" contamination; I pity the poor pax who gets flagged for a full secondary patdown and inspection because of such contamination.
