The whole implementation of these scanners was layers of corruption.

Still worth it IMO - as long as they have to train people to maintain the manual process, its a signal that there are people out there who won't just fold.

They have to do manual pat downs for people who "fail" the scanner, either because there was something that warranted a double check or the computer randomly assigned someone to receive extra scrutiny.

I've walked out of the security perimeter to reschedule after a flight cancellation in an airport with <10 passengers in the terminal. Upon reentering I was "randomly" selected for an explosives swab despite passing the first time with the same bag and not walking more than 50 feet away from the TSA checkpoint.

I "Failed" the scanner once because I was wearing too much deodorant! It decided the titanium or aluminum in my extremely sweaty armpits was clearly explosive.

I felt sorta bad for the TSA guy who had to grope my sweaty armpits to make sure I wasn't a terrorist somehow
