Seeing as how TSA only admits people that are properly screened and cleared to the sterile area, there was obviously no threat to aviation if someone from the sterile area sneaked onto the plane. It's an airline operations/revenue problem at that point, nothing more. If some uber clever terrorist paid his way through an employee entrance without getting himself screened, he's not going to try to then sneak on board an aircraft in front of the GA & hundreds of people and then get booted & caught when an FA tries to figure out why he's sitting in a seat that another angry passenger is ticketed for. He wouldn't have done any of those stupid things to attract attention: he would have bought a ticket like anyone else. The TSA sting operation was pointless.

It's unbelievable that we're paying a team of people to screw around doing bulls#@+ like that.
