CWmike writes "Documents obtained by the Electronic Privacy Information Center (EPIC) suggest that the U.S. Department of Homeland Security has signed contracts for the development of mobile and static systems that can be used scan pedestrians and people at rail and bus stations and special event venues — apparently at times without their knowledge. Under consideration: An Intelligent Pedestrian Surveillance platform; an X-Ray Backscatter system that could detect concealed metallic and high-density plastic objects on people from up to 10 meters away; a walk-through x-ray screening system that could be deployed at entrances to special events or other points of interest, which could be installed in corridors and likely scan people walking through it without them knowing it, EPIC said."
