The ACLU is reporting that the Department of Defense improperly collaborated with the FBI and issued "hundreds of national security letters (NSLs) to obtain private and sensitive records of people within the United States without court approval." According to ACLU Executive Director Anthony D. Romero
The Department of Defense may have secretly and illegally conducted surveillance beyond the powers it was granted by Congress. It also appears as if the FBI is serving as a lackey for the DoD in misusing the Patriot Act powers. At the very least, it certainly looks like the FBI and DoD are conspiring to evade limits placed on the Department of Defense's surveillance powers.
