I don't think just anyone should be able to carry a firearm on a civilian airliner. However, some people should. Just like you need a CCW to carry a
weapon in public, you should need a permit to carry a weapon on an airplane. It shouldn't be given to just anyone, but to those who pass a firearm
profiency test specifically designed for airplanes, and who pass a background test determining they are responsible law-abiding Americans. With people
like that carrying weapons, terrorists won't stand a chance nor will be able to legally get a weapon on board, as the case with the boxcutters.
And that fragmenting ammunition that will not penetrate walls, that stuff is awesome. It'll blast a wound channel the size of a dinner plate. Has
anyone seen the video where they kill a 500 pound boar with one 9 mm round?
