This report from the Washington Post about fusion centres is interesting. I want to investigate fusion centres in more detail.

Dozens of the organizations known as fusion centers were created after the Sept. 11, 2001, terrorist attacks to identify potential threats and improve the way information is shared. The centers use law enforcement analysts and sophisticated computer systems to compile, or fuse, disparate tips and clues and pass along the refined information to other agencies. They are expected to play important roles in national information-sharing networks that link local, state and federal authorities and enable them to automatically sift their storehouses of records for patterns and clues.

Though officials have publicly discussed the fusion centers’ importance to national security, they have generally declined to elaborate on the centers’ activities. But a document that lists resources used by the fusion centers shows how a dozen of the organizations in the northeastern United States rely far more on access to commercial and government databases than had previously been disclosed.

Those details have come to light at a time of debate about domestic intelligence efforts, including eavesdropping and data-aggregation programs at the National Security Agency, and whether the government has enough protections in place to prevent abuses.

The list of information resources was part of a survey conducted last year, officials familiar with the effort said. It shows that, like most police agencies, the fusion centers have subscriptions to private information-broker services that keep records about Americans’ locations, financial holdings, associates, relatives, firearms licenses and the like.
