This is “Cover Your Ass” security, and unfortunately it’s very common.
Exactly what I was thinking as I dealt with airport security last week. Why are we still removing our shoes? If I wasn’t such a coward, I’d try this tonight so I could go pick up my wife at the gate when she gets off her flight. That would be a lovely surprise, and I could help carry all the baby gear. I wonder what the penalty is for using a fake boarding pass to get through security… probably Gitmo. Nevermind.
