I looked it up, and wikipedia defines the FBI as a "United States Department of Justice that serves as both a federal criminal investigative body and an internal intelligence agency (counterintelligence)". My statement is only partially right.
Even so, I am glad they are going green.
Just a nit, the FBI is an investigate agency, not an intelligence agency. That said, I am not sure what additional duties they were assigned in the Patriot Act, so I may be wrong.
