Privatise Airport Security

The Transportation Security Administration (TSA) bureaucracy has taken on a role that private contractors can fulfill more effectively at lower cost with a more traveler friendly attitude.  San Francisco (SFO) is a good example of that.  The most effective role for the TSA would be quality control of private contractors working for the airport or the airlines.  In other words, the private security employees would do the screening and the TSA would do frequent audits to test that no weapons or bombs get through.  This would not only improve the airport environment, but it would also allow for innovation in screening and detection methods.
