I am sure it's all the passengers fault. Not people desperately trying to get to their flight after a long delay waiting for their turn at a bit of ineffective security theatre..
Of course this would be solved by not requiring them to remove their laptops.. Something which would have next to no effect on the uselessness of their scanning anyway..
But no.. It's all the travelers fault. Silly travelers.. They deserve to have their items removed.
Of course it should be quite trivial door then to track down the owners right? TSA is so proud of how well informed they are about the travelers.. Surely they can localise the owners of one of a handful of people? No?
