Benton Love of Houston suggests live drills for TSA employees.

One key to keeping TSA employees sharp would be to have federal agents continually attempt to smuggle dummy bombs and guns through airport security. Pay the agents a bonus for every time they succeed and dock the TSA screeners for every time they allow one to succeed.

Thus we'll incentivize these ersatz terrorists to be creative, find and expose chinks in our armor where they exist. TSA screeners will also be more alert not only for real terrorists, but also for these federal agent infiltrators.
