But here's another thing, x-rays don't detect explosives either, yet they're still used for explosives detection. By TSA's logic, the puffers should be used to detect TATP then if what you say is true.

Here's a good place to read about TATP and why it can't be detected by standard mass spectrometry techniques (i.e., ETP & ETD):

Also you will see a device that might be the thing TurboProf saw used at FRA.
