I will admit that the probability of it happening while you are in your seat is very low. The probability of it happening on any flight in the not too distant future is incredibly high.
The lost revenue argument is lame at best, it's just not so, and your contention that armed Fams decrease safety on a flight is ill conceived and uninformed.
