Personally, I compare the TSA to the security company signs in the front yard, when people don't even have a security system. It might deter the rookie thief (terrorist on a plane) but the hardened criminalt finds it to be juts another potential challenge to work around. Max Power (who sells and installs home security systems) said it best, that the security system is for when you're NOT at home, and the firearm is for when you are at home. Can the TSA, and put that money toward the training of more air marshals. Who is it that cares who is getting on the plane? The TSA, or the airline? Should it matter either way, since the ID and name can be faked anyway. Do you think that someone with nefarious intentions will be showing their OWN ID, and booking the flight in their OWN name?
