Although likely a small percentage of all people screened, the thousands of persons misidentified to the Terrorist Watch List can experience additional questioning, delays, and other effects. Most misidentifications occur because of similarities to names on the Terrorist Watch List; agencies are attempting to reduce the incidence of misidentifications or otherwise facilitate individuals through the screening process. The Terrorist Screening Center and Frontline-screening Agencies are addressing concerns related to Watch List Screening, and an Interagency Agreement is being developed to further ensure an effective means for seeking redress.
