In Tampa last week I was surprised when both private security hall monitors checking IDs wanted to know where the expiration date on my DL was. The first checker before the train said I couldn't pass because my license was expired, and pointed to my DOB. The gatekeeper to the queue airside also took his time scrutinizing my card and mentioning he has to make sure it is not expired. I'm not sure he actually matched my face to the picture, though.

All these ID checks just blow my mind. Is it a threat that an evil doer could switch his identity between check-in and the train to the airside? If so, the risk must be even greater risk that he will change his identity on the 60 second ride.
