Buried in the transcripts of a congressional hearing that took place yesterday is fleeting mention of the federal government’s latest and perhaps most outrageous assault on privacy. If you take an inbound flight from overseas, and a suspected terrorist or supporter is flagged by automated name-check systems as being on the same flight—even if (and particularly if) that someone was denied boarding because they were on some no-fly list—the government regards you as connected with that terrorist, and runs a check on you and everyone else on the plane.

If you have a telephone number that has ever been called by an inmate in a federal prison, registered a change of address with the Postal Service, rented a car from Avis, used a corporate or Sears credit card, applied for nonprofit status with the IRS, or obtained non-driver’s legal identification from a private company, they have you on file.
