Aviation Security: TSA Should Ensure Screening Technologies Continue to Meet Detection Requirements After Deployment, Report to Congressional Addressees [open pdf - 2MB]
From the GAO [Government Accountability Office] Highlights: "The TSA Modernization Act includes a provision for GAO to review TSA's deployment of screening technologies, and GAO was asked to review the detection standards of these screening technologies. This report addresses, among other things, (1) how TSA operationalizes detection standards, (2) the extent to which TSA considered risk when making deployment decisions, and (3) the extent to which TSA ensures technologies continue to meet detection requirements after deployment. GAO reviewed DHS and TSA procedures and documents, including detection standards; visited DHS and TSA testing facilities; observed the use of screening technologies at seven airports, selected for varying geographic locations and other factors; and interviewed DHS and TSA headquarters and field officials."
