the airlines will need to pay to insure against any mistake their screening army makes? pay those extra dollars for our safety as it is put aside because airlines cut corners by hiring low cost incompetent agents trying to stay competitive with each other? Pay those extra dollars to keep people employed and flying after a few planes drop out of the sky because there weren't enough agents at the gates to check a backpack a McVeigh from Michigan brought on as his carry on?
I don't think you given this subject much thought.
My thought is to somehow streamline the TSA operation as it seems hugely cumbersome and inefficient. Domestically, there seems to be too many breeches in security with some able to pass through the agenting without detection of their fire-arms.
