FBI Fusion Centers

Fusion centers are usually set up by states or major urban areas and run by state or local authorities, often with the support of the FBI. They “fuse” intelligence from participating agencies to create a more comprehensive threat picture, locally and nationally. They integrate new data into existing information, evaluate it to determine its worth, analyze it for links and trends, and disseminate their findings to the appropriate agency for action.
