I think they get false positives all the time.

I am a white male that routinely opts-out of the scanners. I've had many many pat downs. One time my bag registered a false positive and I was also subjected to the "enhanced pat-down".

My experience was totally different from OP's. The TSA officers went out of their way to reassure me that false positives are not uncommon, that there was nothing to be afraid of, etc etc. They asked me a few simple questions, but it felt more like they were making conversation to keep the atmosphere relaxed, rather than interrogating me.

I don't recall if further tests of my bags or clothes indicated explosives, but I was let out of the screening room after ~20 minutes.

I strongly suspect that the respectful treatment I repeatedly receive during my TSA interactions are due to (mostly racial) profiling, and luck.



The machines are not binary. They trigger specific materials. Some are going to be much more common than others, and like every process where they have false positives they react differently based upon their incidence rate.


Like ... as common as over the counter bedbug spray?


That was conjecture on his part. If permethrin were the cause, it should be very well know as it's a very common insecticide and lice shampoo.
