Just to add a little more fuel to the fire..
I'm of the opinion that the TSA, though well intentioned has no vision or creativity in their approach towards security. All they are doing is closing barn doors after the horses leave the stable. Of course, that does prevent horses from leaving through that door again but it does nothing to prevent the horses from recruiting a rat to gnaw a hole through the wall.
The screening being done is based on past actions of terrorists, knives, guns and explosives and certainly will keep them from doing that again.
However, Al Quaeda and the terrorist network is a lot more sophisticated and creative than the TSA seems to want to give them credit for. They won't try the same way as before, they'll try something new and creative. My bet is that if most of us took the time we could think of 100 ways to get past or around the TSA with something destructive.
That is where I fault the TSA, they are focusing on the past while ignoring the possibilities of the future. All they are accomplishing now is; 1.) Making many flyers annoyed and driving business away from the airlines. 2.) Keeping honest people honest. 3.) Forcing the terrorists to take it to the next level.
I have no problem with the majority of TSA screeners. Most are dedicated and want to make a difference. It is their leadership who are failing us. Until they begin acting one step ahead of the terrorists rather than one behind, they add no real value to what we had before and are wasting my tax dollars.
