Well, there is someone who wrote down what most have een thinking..
Standardized aircrew id would be a good start, so you know the uniformed guyin front of you is indeed a genuine pilot. Now a genuine pilot would not do crazy things, and as long as he's carrying a decent amount of stuff he might need, you should leave him alone and focus on other security holes
outside the public eye.
I know its a nice show to almost strip down a pilot or cabin crew in front of the travelling public, but the gain from that investment in time and money doesn't really pay off in increased safety.
Just my view. Pilots are no Gods, certainly not. But sometimes they have to jump to a couple too many hoops to be able to execute their actual profession.
