You're right. Trust isn't transitive. Just because a government bureaucracy can design a set of security procedures that's remarkably effective at preventing people from boarding planes with too-large a bottle of shampoo, that doesn't mean it can design a procedure for pilot CCW that makes a damned bit of sense.

Take a look at that. That's the "holster lock" the TSA requires pilots to attach to their weapon whenever they enter the cockpit. This is a weapon-retention system that *requires* the user to finger-diddle the trigger of a loaded weapon every time he uses it.

The pilot still NDed. But he NDed because he had to monkey around with this ridiculous and unsafe system that the TSA requires him to use.
