In response to the attack against the United States on September 11,2001, the Attorney General directed that the fight against terrorism and the prevention of future terrorist acts must be law enforcement’s first priority. He directed every United States Attorney to establish an Anti-Terrorism Advisory Council (ATAC) to serve as a conduit for information sharing about suspected terrorists among federal, state and local law enforcement entities.

In the Eastern District of Tennessee, the ATAC operates as an umbrella organization of local, state, and federal agencies that coordinates activities, develops policy, implements strategic plans, and provides training to combat terrorism. It also coordinates with the other ATACs around the nation and works closely with the Federal Bureau of Investigation’s Joint Terrorism Task Force (JTTF). Member agencies include those from law enforcement, public health, emergency planning and response, the military and the intelligence community.

Some of the cases brought by the United States Attorney’s Office to protect our national security include:

Investigations are undertaken with agents from the FBI, the Office of the Inspector General for the U.S. Department of Health and Human Services, and other federal and state agencies. ACE cases can present facts and issues that warrant criminal as well as civil prosecution.

  • Dr. J Reece Roth, a University of Tennessee physics professor, was convicted after a jury trial of violating the Arms Export Control Act. Roth exported sensitive technical data from an U.S. Air Force research contract to China. The research concerned an advanced weapons project for the development of Unmanned Aerial Vehicles (drones). He was sentenced to 48 months in prison.
  • Roy Lynn Oakley was convicted of violating the Atomic Energy Act for his attempted disclosure of classified information. Oakley attempted to sell the information, which he had stolen from K-25 in Oak Ridge, to a foreign power. He was sentenced to 72 months in prison.
