But pax do not know and it appears that neither do you. There is no requirement to show ID. If you don't, you will receive secondary. And there is no requirement to take off your shoes unless they set off the WTMD or the HHMD even though many TSA officers "recommend" that all shoes come off. Yes, there are secret guidelines (SSI), like what is the requirement for a profile shoe even though Hatfield has publicly stated the one inch rule. So pax do not know what is expected since consistency is not present many times.
