1. Plus, a terrorist...

could possibly get their hands on the gun. Why make that easier?

3. Anyway, all countries are moving toward air marshalls

2. I imagine that would be pretty hard to do and stay employed

Not sayin' it's a bad idea in theory, but in practice it might not be good for your career in aviation.

4. That would make you a poor pilot...

5. Work place violence.

6. Seeing as he has ready access to a myriad of buttons and controls...

Damn Poe's Law...

7. I think that axe they keep in the cockpit would be just as dangerous.

8. Rather have a gun in the cockpit

than in the passenger compartment.
