The safe way is to make sure that no weapons get onto the aircraft.
Hear hear. I remember having a conversation with a very senior police officer at about the time “sky marshals” were being mooted in the UK - he didn’t like the idea himself plus there were never going to be enough to adequately cover more than a few flights at a time, so they would be the “risky” ones. I opined that if a flight was deemed that risky, it wouldn’t be leaving the gate if I had anything to do with it...
