O'Hare gave up on this last night once lines got bad. See, regardless of what you think of these procedures (you can guess what I think of them), they take a lot longer to process people. Sure, it would get better over time, but nowhere near where we are (or were) at with the metal detectors and bomb sniffers.
This is bureaucracy out of control, plain and simple. Mind you this was a GOP thing to begin with, but it's not like it got better since 2008. I think the video above is simply awesome satire, and boy, it nails the problems with the TSA perfectly.
