Most of the security people in the US are low paid and poorly trained.
Unfortunately, this is true. Many of them are retards. No tolerance TSA regulations are written so that security people do not have to think. Just blindly follow the rules and search 90-year-old grandmothers.
Poorly trained or not, the TSA screeners were doing their job and this woman is a crybaby. The esteemed doctor doesn’t bother to tell us if her carry-on luggage or her shoes pinged a false positive on the explosives wipe, which seems to me to be very likely given the triple screening she went through.
