I've also been called to do gate screenings on people whose SSSS boarding passes were issued airside ... they clearly didn't come through the checkpoint (no initials on the passes). Didn't inquire as to the circumstances ... just screened them and sent them on their way.
The one time I was SSSS'd, both of my BP had the dreaded haraSSSSment crap. I refuse to show ALL of my BP to the TSA, only the BP for the particular flight segment originating from their airport. I was not stopped at the gate in ATL for my second BP not having the magic scribbles.
