This is supposed to be a surprise? I suspect that a lot of the "screeners" are gay or lesbian and are looking for a chance to molest passengers without risk of getting what they would in the real world. The rest, I would judge, are mostly hired to meet "affirmative action" goals and are about as competent as you would expect.
We flew out of Houston last year about this time (and out of Sacramento on the way back). i could see at least a couple of ways to get a bomb on board if I wanted to and was willing to go with the plane. And at least a couple that would allow me to LEAVE a bomb on board for later effect. And no - i ain't saying. If TSA sends somebody with a subpoena, I'll appear before the Grand Jury and refuse to answer, citing Fifth Amendment, until they grant immunity. Or agree to hire me as a consultant at a reasonable fee.
You mention it and they would probably arrest youI see no reason to tell ALL i know. And I'll bet that, if you watch the so-called security procedures, you'll see a few holes. I suggest that you do NOT mention them to the screeners. or anybody else.
