I am referring to the items which TSA lists on their website as permitted, and what they list as process.

Sometimes it feels as if the rules are made up as they go along. Airport A permits something if the sky is grey, there is an R in the month, and the screener is in the first hour of their shift. Airport B permits the same item only in months containing a A, the sky is blue, and the screener had chicken for lunch. Airport C permits the same item when the sky is black.

Yet the TSA website clearly states that the item is permitted.

As examples, take Nexus card, or the non-removal of certain medical devices. And here it is even more unclear - for instance the statement from at least one TSA poster than 1 gallon size bags are permitted at the checkpoint.
