What prevents the TSC from violating the civil liberties of Americans?
The TSC only receives information collected by other government entities with pre-existing authority to do so. Each agency that contributes data to the TSC must comply with legislation, as well as its own policies and procedures to protect privacy rights and civil liberties. The handling and use of information, including information about U.S. citizens and legal immigrants, is governed by the same statutory, regulatory, and constitutional requirements as if the information was not to be included in a TSC managed database.
