Terrorists have no need for a gun, box cutters have proven very effective. Don't think they can't get them through security.
That's my point. You can't guarantee that every pilot has the nerves of steel that Clint Eastwood does in the movies.
Some yahoo in the back with box cutters may draw a pilot out of the cockpit. Are you suggesting that EVERY pilot will do exactly what he/she is told in this instant? Hell some can't follows SOPS at the best of times.
Drawing the pilot out with guns a-blazing will give the terrorist a chance to nab the gun.
We could go over these scenarios ad-nauseum but they won't convince me that its a good idea to arm pilots simply because of the statistics I quoted earlier. People most often are shot by people they know and people are sometimes shot by their own weapons. The chances of the average passenger being on a hijacked flight is much more remote than getting shot and killed by someone they know. Put the gun on the airplane, and you have now exposed everyone to that risk.
If you have no guns on board, there is a chance the airplane will be hijacked. An extremely remote chance. Put a gun on every airplane, and now you have a chance that SOMEONE will be shot. Even better odds than being hijacked simply because you added a lethal weapon to a situation where there was none before.
I don't have a clue? Maybe not. Let's wait 6 months and see....
Which countries in the world have the highest incident of violent crime? Sorry gohogs. Too late. You're already 10 times more likely to be shot than I am simply for living in the US wich has lax firearm laws. Duhhhh....
