Having worked for TSA for quite a while, I can say that program, as a whole, was one of the best Counter Terror programs implemented after 9-11. Even though no FFDO, to date, has intentionally fired his weapon in a plane, I believe it has quite a deterrent effect on many types of attack. I wonder, are they just afraid of having a gun on a plane? Do they realize that the pilot with the gun can cause far more destruction simply by pushing forward, than he does with the gun?
Really though...not shocking in the least.
