With all the commotion over the invasiveness of the naked-body scanners used by the United States Transportation Security Administration (TSA), one question that has been ignored is who is profiting from TSA’s use of the body scanners? Mark Hemingway and Tim Carney at The Examiner discovered the shameful answer: George Soros, Michael Chertoff, and a number of lobbyists.
I'm sure the same applies to trucks being scanned (with possibly different names for the pigs snuffling in the public trough).
Congress has no power to do anything anymore. Or at least they're too gutless to actually exercise it.
