Washington Post reporters Dana Priest and William Arkin have released a companion piece called Monitoring America to their in depth investigative report Top Secret America.

Their key findings on our growing surveillance state:

* 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.
