Yes, I'm sure the TSA has a team of monkeys working around the clock analyzing ticket refunding practices looking for a pattern . . . trying to crack the case . . . long into the night!

The intention of requiring a boarding pass in your name to get through security is not to prevent what is being attempted here, but just to reduce the number of people going through security. This allows fewer screeners and equipment to spend more time analyzing the reduced number of people passing through security lines.

Security isn't defeated, you're just defeating the reasonable rule. It's comparable to using the biz or first class lavs when you're in coach.
