Oh, so now you're a lawyer? Show me where it says in the Constitution that TSOs have a right to pat me down after I set off the WTMD.

As it happens, both are authorized by Congress under the Commerce Clause of the Constitution.

You know a lawyer is reading this thread. What in the world makes you think that your TSO training is remotely sufficient for you to opine on constitutional requisites for federal law?

I'd strongly recommend you learn from your colleague, HSVTSO Dean, who is professional enough to recognize when he doesn't know something and simply says so, rather than making up the most outlandish nonsense (which I sincerely hope you never act on).
