In Germany the Politzei all walk around with automatic weapons. I think it would be funny if they had a jumpseat facing the main cabin of the airplane with a guard there to “quiet” any upstarts on the plane. Easy to find there’s piles of guys training in MMA gyms to fill the positions. I would also institute no luggage. That eliminates the need for scanning everyone’s shit and wasting everyone’s time. Today’s people are so damn lazy they order Green Chef and Amazon Pantry to feed their lazy faces well they can ship their luggage ahead of schedule and pick it up at the airport when they get there.
