If you ask a TSA employee, their job is not catching terrorists. Their job is preventing "dangerous items" from getting onto an aircraft. The problem is that if that really is their job, they're horrifically bad at it.
That's not their job.
TSA was founded for several purposes: 1. To shift the power over airport security to the federal government (several subpurposes to this -- among them shifting responsibility in the case of another failure, and creating a single point of influence for contractors to target.)
Don't confuse the direction of the Agency with the directives issued to their front-line morons.
