As always.
Again with the racial profiling. Yes, the hijackers were Saudi.
But you cannot focus on EVERYTHING.
Focusing means to pay more attention to one thing than to other things.
If you develop a rules system that focuses on arabians, then, by definition, you are paying less attention to other passengers.
Which is why I gave the example of using the white girlfriend to get the weapons through security.
As for a terrorist being able to out draw a uniformed security guard, that depends upon the terrorist having a hand gun and if the terrorist has managed to get a hand gun onto the plane, there's nothing any sky marshal is going to be able to do to stop them.
My scenario relies upon the guards being better armed than the hijackers. If we can't achieve that, then we need to seal the cockpit from the rest of the plane.
