Well, it sounds dumb and really it is. BUT, in arming the airlines pilots, it was never the goal that they would be the ones defending the airliner and passengers,
beyond the cockpit. That's the key. Those firearms are to be used IF the cockpit door is breached.
From the cockpit back is the responsibility of TSA or other Federal agents traveling on the plane. Any Federal agent flying armed has received training on what to do in the event of a highjacking. Not on how to use their firearm (that's done elsewhere), but how to protect the cockpit.
So, while I still think it's somewhat silly to lock firearms (almost ANYTIME, almost ANYWHERE), there is some madness to their method (AD's notwithstanding) (((
