All I know is that we haven't had another hijacking, or another plane flown into a major US building since 9/11/01, and that tells me they must be doing something right.


We know more than that. For instance, we know that the technique used to hijack the airplanes no longer works once people have expanded their sphere of possible outcomes.

In fact, that technique failed as soon as the passengers on the 4th plane learned about one of the other planes from a cell phone call. They acted to foil the terrorists (at the cost of their own lives). If they had known a little earlier, I doubt the terrorists would have gained access to the cockpit and the plane would likely have landed safely.

That's what we know. Prior to the first plane hitting a building - this sort of action was inconceivable to the average civilian. This is no longer true and it will never be true again.

The other thing I know is I have a right to personal grooming tools and I'm fed up with buying new ones everytime I get on a plane.
