In a hearing before the Senate Committee on Commerce, Science, and Transportation, Sentors asked TSA Administrator John Pistole tough questions about the privacy and health implications of airport body scanners. Senators also asked about the invasiveness of pat-downs and the problems that the machines pose for religious objectors. Pistole failed to provide proof of independent studies regarding radiation risks and consistently downplayed privacy and religious concerns. EPIC has filed a lawsuit to suspend the body scanner program, calling the program "unlawful, invasive, and ineffective." For more information, see EPIC: Whole Body Imaging and EPIC: EPIC v. DHS (Suspension of Body Scanner Program).
