Fidelity, Bravery, Integrity
- Official Motto of the FBI

The Federal Bureau of Investigation (FBI) is a governmental agency belonging to the United States Department of Justice that serves as both a federal criminal investigative body and a domestic intelligence agency, responsible for counterintelligence and counterespionage within the homeland Untied States. Also, it is the government agency responsible for investigating crimes on Indian reservations in the United States under the Major Crimes Act. The branch has investigative jurisdiction over violations of more than 200 categories of federal crime.

The FBI was possibly the most frequent source of Delta Green agents in the years after Fairfield's death, due to a typical FBI agent combining lawful powers to arrest and search, firearms and combat training, formal training in investigations and evidence collection as well as a national intelligence network they can employ in their search for the unnatural.

In Crumpton's "The Art of Intelligence"

On 2013-05-20, Del Rio wrote to the DGML:

I was just reading Henry Crumpton's The Art of Intelligence. He was a CIA man in the 80s and 90s who served some time with the FBI's counter-terrorism unit starting a little prior to 9/11/01. He has some rather striking insights into the FBI's approach to (and their essential failure to adequately counter) domestic terror threats.

First, he has great respect for the FBI's professionalism and thoroughness on their own turf, which is investigation, with the intent to arrest and convict. But, for example, when he inquired about viewing the FBI's dossier on a terrorist who was known to be visiting or residing in the USA, he was told that information wasn't readily available. Why not?

1. Because the FBI is divided into field offices, which work cases almost independently of each other. So, they act largely autonomously, and keep their own council on what investigative activities they are performing. If any of them *did* know anything current about this guy, you would have to pretty much call around all of them and ask.

2. Because they are an investigative organization, if there's no crime and no crime scene, there is no investigation. They don't just track suspicious people, they respond when a crime occurs.

3. The FBI does not pursue leads that they gather during an investigation that do not relate to the crime in question.

4. To the FBI, data is evidence, it gets locked in a vault with a demonstrable chain of custody. They do not allow other organizations to view or handle it, because that runs the risk of tainting it for the trial.

5. The FBI discusses data extensively at daily briefings (in the field office conducting the investigation), but does not like to write reports. They do not want their bad conjectures, false leads, and plain old mistakes being committed to paper, subpoenaed by a defense lawyer, and used against them during a trial.
