The Transportation Security Administration has expanded its Visible Intermodal Prevention and Response (VIPR) program to perform warrantless searches at various locations, including festivals, sporting events, and bus stations. The VIPR program uses "risk-based" profiling and "behavior detection" to search and detain individuals. Members of Congress have opposed these searches, and the GAO has questioned the validity of TSA's behavior detection and dispelled behavior detection effectiveness. Last year, EPIC prevailed in a lawsuit against the TSA that revealed the agency's plan to deploy body scanners outside of the airport at bus stations, train stations, and elsewhere. For more information, see EPIC: EPIC v. DHS (Mobile Body Scanners FOIA Lawsuit).
