The FBI has quietly changed their primary mission.

The FBI Fact Sheet has declared for decades the primary function of the FBI was “law enforcement.” A Washington-based National Security lawyer noticed earlier this year that the Fact Sheet has changed to say the primary function is “national security.”

An FBI spokesman would not confirm the day the change to the FBI’s Fact Sheet was made but said the change is more accurate.

“When our mission changed after 9/11, our fact sheet changed to reflect that,” FBI spokesman Paul Bresson told Foreign Policy online. He pointed out that counter-terrorism is the agency’s biggest mission right now so it’s proper to say their primary function is national security.

The FBI doubled the amount of agents working on counter-terrorism between 2001 and 2009 according to a 2010 Inspector General report.
