The Oregon Terrorism Information Threat Assessment Network is one of several Federal Fusion Centers spread across 77 U.S. cities that collaborate with local law-enforcement agencies on suspected terrorist threats.

In the fall of 2011, a key Boston police counterterror intelligence unit -- funded with millions of dollars in U.S. homeland security grants -- was closely monitoring anti-Wall Street demonstrations, including tracking the Facebook pages and websites of the protesters and writing reports on the potential impact on "commercial and financial sector assets" in downtown areas, according to internal police documents.

A Department of Homeland Security division produced daily briefings on "peaceful activist demonstrations" during the height of the Occupy Wall Street protests, documents released Tuesday revealed.

The documents show that DHS, the sprawling Federal agency ostensibly created to combat terrorism after the September 11 attacks, routinely spies on peaceful First Amendment activities and required daily briefing on the extent of media attention being given to Occupy Wall Street activities.

Department of Homeland Security documents obtained recently by the Partnership For Civil Justice Fund (PCJF) reveal that the agency, founded for combatting terrorism, has a policy of spying daily on peaceful activists and protesters in the United States.

Government documents obtained by the Partnership for Civil Justice Fund (PCJF) through its FOIA records requests reveal that the Department of Homeland Security (DHS), an agency created after the September 11 attacks under the rubric of combating terrorism, conducts daily monitoring of peaceful, lawful protests as a matter of policy.

A sample of the extensive news coverage of the documents, released to PCJF in late December 2012, showing that the FBI and DHS extensively monitored and communicated about the Occupy movement.
