Relaxez-vous....
Surely this is about the pros and cons of arming our chosen profession, not directing abuse at our colleagues!
As one who opposes the introduction of any weapon onto my aircraft -in any form- I would consider that the two main forms of security on board are:
1. Prevent certain individuals from boarding.
2. Prevent any that slip through the net from getting anywhere near the flight deck.
I think we refer to this as a swiss cheese model...?
As to how we go about achieving those two objectives that is of course up for discussion... but I do not believe that arming us at the sharp end is the answer. In fact, it does seem rather foolish and would not make me feel at all safe at work.
I for one, hope we do not see any weapons introduced ever.
