More evidence that American travel is headed for a two-tier security theater that is reasonable and light for rich people and business travellers, and increasingly awful and invasive for everyone else: as Pre-Check expands, people who fly often enough to make it worth spending $85 will be able to keep shoes, jackets and belts on and avoid pornoscanners (including the new more radioactive versions). Us dirty foreigners, as well as people who save carefully for one trip every couple of years to see their families, will get the ever-expanding Grand Guignol treatment, especially since everyone with any clout or pull will be over there in Pre-Check land, getting smiles and high-fives from the TSA.
