My typical airports have completely eliminated metal detector only lines except for Pre✓™. Pre✓™ seems like extortion - I have a passport, DHS has my fingerprints (for unrelated reasons). Why should I jump through additional hoops, and give them more money for something that they've already collected from me? If they really wanted to know if I was a flight risk, wouldn't they have already used all of the information they already know about me? If not, why!?
