The National Network of Fusion Centers was established after the September 11 attacks to allow collaboration across jurisdictions in order to respond to criminal and terrorist activity. It is a decentralized, distributed, self-organizing network of individual fusion centers and their respective partners within each center's area of responsibility. The process is a method of managing the flow of information and intelligence across levels and sectors of government to integrate information for analysis.[1] Fusion centers rely on the active involvement of state, local, tribal, and federal law enforcement agencies—and sometimes on non-law enforcement agencies—to provide intelligence for their analysis. The intent is that, as the diversity of information sources increases, there will be more accurate and robust analysis that can be disseminated as intelligence.
There are a number of documented criticisms of fusion centers, including relative ineffectiveness at counterterrorism activities, the potential to be used for secondary purposes unrelated to counterterrorism, and their links to violations of civil liberties of American citizens and others.[7] One such fusion center has been involved with spying on anti-war and peace activists as well as anarchists in Washington state.[12]
David Rittgers of the Cato Institute has noted:
a long line of fusion center and DHS reports labeling broad swaths of the public as a threat to national security. The North Texas Fusion System labeled Muslim lobbyists as a potential threat; a DHS analyst in Wisconsin thought both pro- and anti-abortion activists were worrisome; a Pennsylvania homeland security contractor watched environmental activists, Tea Party groups, and a Second Amendment rally; the Maryland State Police put anti-death penalty and anti-war activists in a federal terrorism database; a fusion center in Missouri thought that all third-party voters and Ron Paul supporters were a threat; and the Department of Homeland Security described half of the American political spectrum as "right wing extremists."[13]
