Pilot Pete,
Your rationale for not searching flight crew when you go airside is, I'm afraid, specious.
As soon as you have people allowed airside without a search then you also have people who could be coerced (someone could kidnap your family) into carrying naughty things through to hand to the bad guys.
It's has nothing at all to do with you and what you could do with your aircraft.
Sorry to point out the bleedin' obvious ... ;-)
