Also, I don;t think the airlines has a problem with trusting the pilots with the gun outside the cockpit. It's more about not trusting the terrorists access to the armed pilot...... while he's outside the cockpit. Remember, pilots are not trained law enforcement officers, nor should they be, nor do they need to be. They need to be trained well enough to KILL any humphead lucky enough to get past the air mashals and any other agents in the aisle, and dumb enough to try and breach the cockpit door.
