“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,” gizmodo.com reports with breathless (if properly paranoid) optimism. “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 that’s just the good part. The bad part: it’s only a matter of time before the Fuzzbuster lookalike molecular scanner finds its way from airports and border crossings to thousands of practitioners of “stop and frisk” policing. Concealed carry? Holster makers are already working on solutions. Or will be, soon enough.
