It's been pointed out time and time again, even on PPRuNe, that the main perceived threat in mind with regard to aircrew is the "innocent" crew-member who is coerced into carrying an item into the sterile area for use by a culprit in his illegal activities.
Its also been pointed out to the numerous agencies concerned that aircrew are actually part of the solution rather than being considered part of the problem.
The coerction argument has been put forward by people with little or no understanding of how a crew work together in the REAL world.
Quite frankly, the notion that someone would be able to hold it together in any normal sense in such a stressful situation is completely laughable, with the inevitable outcome being that person being stood down or removed from duty.
I'm afraid the same security apparatus that has dreamt up this Hollywood inspired scenario is the very same apparatus that assumes that armed airside Police Officers (as they are here in the UK) are never screened as they could never be "coerced"
Its beyond stupidity.
