I went through a security check at the Atlanta airport yesterday and one of the ladies asked it she could check my bag. I, of course, said yes, and she took it over to a table a wiped a cloth on the handle and put it under some type of scanner or light maybe.
I’ve never seen this before (I travel mostly within Europe) and am guessing it is to check for explosive and/or drug residue. Is that correct? How can the handle be that sensitive (I presume if I was carrying a weapon or explosive, I’d wash my hands at some stage)? Am I supposed to sweat it out via my hand on the handle? Why not just swipe my hands - or everyones hands? Surely this would be “allowed” under the authority given to security personnel by the FAA? What if the baggage claim caroussel attendent touches hundreds of bags and spreads the residue?
Since I was carrying neither drugs nor explosives I can’t even tell you if the system works or not…but it doesn’t seem overly efficient.
