Before some pansy bemoans how an innocent passenger might be harmed by a rock salt projectile...let be clear that I was referring to a non-fragmenting projectile in the hands of a responsible American who is trained in the use of firearms from childhood.
As it was in this country until the statist stole our national heritage from patriotic Americans and redefined government agents as the only people who can be trusted with firearms in a hostile situation...
I actually envision some sort of "air militia", whereby volunteers who fly regularly could train, say one weekend a month, not only in the proper use of firearms on board a plane, but also on how to spot suspicious characters and to respond appropriately and effectively in various types of situations. Such volunteers could then receive discounts on their tickets.
Or, I guess we can just keep feeling up pregnant women's knockers.
