Watching Sesame Street and The Muppet Show will establish the identity of the most prominent characters very quickly. The only test that doesn't seem to be carried out is the Idiot Test, presumably because most would fail.
And why should the checks for "Security" Staff take any longer? They don't know anything about security. They are shown how to look at a screen and tip out your bag for you while making snide remarks at your expense. And that's just the Flight Crews, both ends of the tube.
If you want to know about security ask the Israelis. Their method (proper profiling) costs money to implement through thorough training but the results are worth it. Teach smart people how humans work, not how machines work and you will see immediate improvements and a much higher success rate.
Annoying the general public achieves nothing positive whatsoever. Apart from derisory comments such as can be found all over pprune on this subject.
Security staff asking for pay rises and going on strike because their working conditions are crap is not the answer. They should ask for better training, then they'd be better qualified and could rightly demand a better salary befitting their level of knowledge.
It's all been said before..............
