23208910 story DHS Tries To Hide Mobile Scanner Details 201 Posted by Unknown Lamer on Thursday August 18, 2011 @06:15PM from the the-new-black dept. OverTheGeicoE writes "The Electronic Privacy Information Center filed a Freedom of Information Act request last year (PDF) with the US Department of Homeland Security, whose Transportation Security Administration has been investigating the use of x-ray scanning technology for covert use in more public places, like train stations and even ordinary city streets. TSA has tested interesting devices like the Z Backscatter Vans both privately and on members of the general public. EPIC recently received new documents from DHS. Some of the documents are almost completely black from redactions."
