Police departments across the country are starting to create networks of databases called “fusion centers” in an effort to detect and prevent acts of terrorism. The ultimate objective is to create a nationwide reporting system of suspicious behaviors so that the authorities can “connect the dots” before an attack can occur. Civil liberties groups claim these fusion centers are beset with legal and practical problems. One legal problem is that the police should not be opening files on people because they exercised their right to free speech, such as demonstrating against the foreign policies of the United States. One practical problem is that the police are gathering so much mundane information that practically anyone could end up on a list of “suspicious” persons because some official arbitrarily decided to fill out a tip sheet. Join us for a discussion of the pros and cons of this newly proposed system of policing.
