Big Brother: Beta Version

The TSA has been researching ways to "screen" us everywhere -- it's not just for the airport anymore.  They responded to the linked blog post (probably via their nifty rapid response TSABlogTeam) to claim that they have no plans to implement this technology for other forms of mass transit or on pedestrians, presumably.  I guess I have two issues with that: 1) why then are they wasting our money on this kind of research, and 2) I don't believe them.
