Since seeing you naked  at the airport isn't sick enough (not to mention the extra doses of radiation), the government wants to scan everything else with portable  backscatter  vans.  I'm bet they'll use these to start scanning homes too, if they already haven't.  They'll probably use the old excuse that they will be employed in the "War and Non-State Approved Drugs".  Is there nothing the government won't do to watch your every movement, every minute of everyday?

I guess my dentist is full of it when he puts that lead vest on me when he takes pictures of my teeth.

Any how, it appears American Science and Engineering, Inc, the  maker  of  these  instruments  derives  virtually  all  of it's 'business' from the government.  Isn't that wonderful how the government gets you to pay for your own enslavement and violation of privacy?
