The least they could do is periodically play Reveille from time to time to wake sleeping TSA agents. Going through DFW a couple of years I was floored seeing a sleeping TSA agent guarding some unused exit.
Would be tempting to walk up to one and do just that (I know, I know, only in our imagination, they’d take it with very ill humor).
Oh my gosh - I’ve seen sleeping TSAs at DFW (post #34) several times. The last guy was doing a head-bob thing sitting in a chair right at security. I took out my phone and started videoing him, but my pilot husband was not amused by either one of us.
