Nothing's foolproof, sweetie.

But perhaps I should rephrase my first question - how many United States airline employees have you heard of going "postal"???

And no one has yet thought of a system to put into place regarding screening the screeners...and who is good enough, has high enough security level to be "the one" to open the screening checkpoint and the airport in the mornings? I don't know how it works exactly, but I know that Federal law enforcement carrying a weapon with paperwork does not have to be screened. Loophole? I'm willing to put my faith into his hiring agency and feel quite secure that he is no threat to my flight.
