The Terrorist Screening Database or TSDB is the central terrorist watchlist consolidated by the FBI's Terrorist Screening Center and used by multiple agencies to compile their specific watchlists and for screening. The list consists of 400,000 unique names and over 1,000,000 records (some are alias or name variant) as of September 2008.[1] 1,600 nominations are suggested daily, 600 names are removed and 4,800 records are modified by the U.S. intelligence community. Approximately one out of twenty of the people on the list are U.S. citizens or legal permanent residents.[2]

The TSDB is fed from two primary sources: international terrorist (IT) information from the Terrorist Identities Datamart Environment, a central database on known or suspected international terrorists maintained by the National Counterterrorism Center (NCTC) and domestic terrorist (DT) information from the Federal Bureau of Investigation (FBI). The TSDB in turn is used to compile various watchlists and screening systems:

  1. No-fly listDepartment of Homeland Security
  2. Selectee listDepartment of Homeland Security
  3. Interagency Border Inspection System (IBIS) – Department of Homeland Security
  4. National Automated Immigration Lookout System (NAILS) – Department of Homeland Security migrated to Treasury Enforcement Communication System (TECS)
  5. Consular Lookout and Support System (CLASS) – Department of State
  6. Criminal Justice Information Services Division Warrant Information – Department of Justice
  7. Violent Gang and Terrorist Organization File (VGTOF) – Department of Justice
  8. Interpol Terrorism Watch ListDepartment of Justice
  9. Air Force Office of Special Investigations Top Ten Fugitive List – Department of Defense
  10. Automated Biometric Identification SystemDepartment of Defense
  11. Integrated Automated Fingerprint Identification SystemDepartment of Justice

The Justice Department's Office of Inspector General has criticized the list for frequent errors and slow response to complaints. An Office of Inspector General audit found that 38% of a 105 record sample contained inaccuracies. The FBI has said it is redressing errors, and a 2006 review of the no-fly list reduced its size by half, from 71,872 records to 34,230 records.[3][4]
