USA Today reports that the TSA has been adding air travelers who forget their IDs to their list of potential terrorists. The logic being that this would pick up on terrorists who are looking to discover holes in the TSAs safety process.

The paper reports that they spoke to the TSA chief about this practice, and that later that day he called back to say that they would be discontinuing the practice, and if the on-site officials could determine the traveler's identity, that traveler would not be added to the list. The chief also stated that the records that had already been collected on forgetful fliers would be expunged from their database.

So... How do you collect personal data for someone who has no ID? What exactly was the TSA recording in their database?
