Experience has shown that there is no single source for information related to terrorism. It is derived by gathering, fusing, analyzing, and evaluating relevant information from a broad array of sources on a continual basis. Important information can come through the efforts of the Intelligence Community, Federal, State, tribal, and local law enforcement and homeland security authorities, other government agencies (e.g., the Department of Transportation, the Department of Health and Human Services), and the private sector (e.g., the transportation, healthcare, financial, and information technology sectors). Commonly referred to as homeland security information, terrorism information, or law enforcement information, this wide-ranging information can be found across all levels of government as well as in the private sector.
