Speaking as an ignorant SLF, would it be fairly accurate to assume that on Mr. Boeings Big Jet, the sky marshal will always be placed on the upper deck?
So you then have a situation where the marshal is not one of 350 but one of 20.
And with online check-in, the passengers can choose exactly where they want to sit.......2 on the upper deck to disarm the marshal and die for their cause, 5 on the lower deck to sieze the cockpit once the disarmament is complete.....
And everyone keeps telling me about low-velocity rounds not puncturing aircraft skin. What about a window?
I think it goes back to the argument "when you have a hammer, every problem looks like a nail." I wouldn't expect anything less from a country where billboards proclaim
"Society is safer when you don't know who's armed."
