TSA Agents Smuggle Bombs Into Airports

It is true. TSA Agents are smuggling bombs into airports to test the system.

Someone please tell me this doesn't actually happen. "Hi Mr. Passenger. I'm a TSA manager. You know I'm not lying to you because of this official-looking laminated badge I have. We need you to help us test airport security. Here's a 'fake' bomb that we'd like you to carry through security in your luggage. Another TSA manager will, um, meet you at your destination. Give the fake bomb to him when you land.

Well it hasn't happened yet. But could it? Suppose some jihadi joins the TSA? With their most excellent screening procedures for new agents. They must be good. Look at the people doing the "job". And then suppose the TSA jihadi substitutes a real bomb for the fake one? The fun will never cease.

The Romans, who supposedly knew a thing or two about security have a question:

Quis custodiet ipsos custodes?
