Monitoring America, by Dana Priest and William M. Arkin. The Washington Post, 20 December 2010.
Today's story, along with related material on The Post's Web site, examines how Top Secret America plays out at the local level. It describes a web of 4,058 federal, state and local organizations, each with its own counterterrorism responsibilities and jurisdictions. At least 935 of these organizations have been created since the 2001 attacks or became involved in counterterrorism for the first time after 9/11.

The months-long investigation, based on nearly 100 interviews and 1,000 documents, found that:

* Technologies and techniques honed for use on the battlefields of Iraq and Afghanistan have migrated into the hands of law enforcement agencies in America.

* The FBI is building a database with the names and certain personal information, such as employment history, of thousands of U.S. citizens and residents whom a local police officer or a fellow citizen believed to be acting suspiciously. It is accessible to an increasing number of local law enforcement and military criminal investigators, increasing concerns that it could somehow end up in the public domain.

* Seeking to learn more about Islam and terrorism, some law enforcement agencies have hired as trainers self-described experts whose extremist views on Islam and terrorism are considered inaccurate and counterproductive by the FBI and U.S. intelligence agencies.

* The Department of Homeland Security sends its state and local partners intelligence reports with little meaningful guidance, and state reports have sometimes inappropriately reported on lawful meetings.
