This one sounds a lot scarier than any of the new fascist technologies I've read about. This could essentially be something like Orwell's telescreen.

Hidden Government Scanners Will Instantly Know Everything About You From 164 Feet Away
Within the next year or two, the U.S. Department of Homeland Security will instantly know everything about your body, clothes, and luggage with a new laser-based molecular scanner fired from 164 feet (50 meters) away. From traces of drugs or gun powder on your clothes to what you had for breakfast to the adrenaline level in your body—agents will be able to get any information they want without even touching you.
And without you knowing it.
The technology is so incredibly effective that, in November 2011, its inventors were subcontracted by In-Q-Tel to work with the US Department of Homeland Security. In-Q-Tel is a company founded "in February 1999 by a group of private citizens at the request of the Director of the CIA and with the support of the U.S. Congress." According to In-Q-Tel, they are the bridge between the Agency and new technology companies.
Their plan is to install this molecular-level scanning in airports and border crossings all across the United States. The official, stated goal of this arrangement is to be able to quickly identify explosives, dangerous chemicals, or bioweapons at a distance.
The machine is ten million times faster—and one million times more sensitive—than any currently available system. That means that it can be used systematically on everyone passing through airport security, not just suspect or randomly sampled people.
