mn_voyageur; Welcome to FT. ^^
I believe your answer to be correct. If TSA is seen to be backing away from one facile thing they do, the circus as a whole becomes visible in a different light, and is in danger of collapse

ie how could shampoo be dangerous yesterday, but not today? People only passingly involved will begin to question the whore

on water, the nonsensical demands for GIPID to check against your home printed BP, the need to have shoes upright in the X-Ray, as well as more telling ignorance symptoms such as the blind spots for non-liquid explosives.
