I think the two comments above yours are poking fun at the guy who is committing a felony by lying to federal agents. They're just making it obvious what he's doing is really shitty, anti-social behavior.
Lying to TSA and other government representatives is patriotic
You are grossly misinformed and making an assumption.
You're thinking of being interviewed by a Federal agent. At no point are you being interviewed at a TSA checkpoint. Generally, they have two agents present for that so they can act as witnesses for each other. The FBI specifically uses the 302 for such an interview. Can you cite the relavant US Code here? I can.
Further, you're assuming I'm lying.
As someone who was present (in the room) as DHS was being formed and witnessed the negotiations around the TSA, the "really shitty, anti-social behavior" is sharing misinformation.
