EPIC has filed a Freedom of Information Act lawsuit against the Department of Homeland Security for unlawfully withholding documents concerning mobile body scanners. The mobile scanners can be used to monitor crowds, peering under clothes and inside bags. EPIC previously obtained documents describing the federal agency's plans to expand the use of these systems at railways, stadiums, and elsewhere. EPIC's suit asks a federal court to order disclosure of nearly 1,000 pages of additional records detailing the controversial program - records the agency has refused to make public. EPIC also has an ongoing lawsuit to suspend the controversial airport body scanner program. For more information see EPIC: Whole Body Imaging Technology and EPIC: EPIC v. DHS: Suspension of Body Scanner Program.
