At SJC about 2 weeks ago, the security line ID checker had a sheet of clear adhesive labels with the letters "SSSS" printed on them and a red crayon, which were being liberally applied to, it appears, the BP of anyone presenting an ID other than a driver's license, of which there seemed to be a few in the line just in the time I observed. TSA would give the red carpet treatment (full sitting and standing wand, and bag search), then punch a hole in the BP – not that anyone seemed to be checking this when boarding.

Her uniform said "Globe Security Services"… I think? For a moment I thought this might be a WN thing, since they share the checkpoint, but the gate agents told me this is an AA contractor. (The line referee didn't seem to be letting anyone use the first class line, even without looking at their BP, so maybe there's a bit of the WN mentality? ) Aside from the general weirdness of one non-airline employee applying the SSSS based on a relatively arbitrary non-TSA criterion (one not even applied at other AA airports), isn't there an absence of concern with due process when a private party (the airline/a subcontractor thereof) decides who they don't like, then TSA proceeds to grill those folks extra?
