Which is a huge part of the problem, zero accountability. The whole agency needs to be abolished, with it being replaced with a smaller agency that just regulates and tests the private contractors hired by the airports to do the screening.
What likely would happen is they would do a poor job of regulating and managing those contractors then we would be hearing about all the ex-felons or unvetted or foreign agents that contractors managed to hire. If they can't manage their own employees why would they be able to manage a 3rd party contractor's?
