What the FBI Does
FBI's Main Goal
The FBI's main goal is to "protect the American people and uphold the Constitution of the United States". This means they work to keep everyone safe and make sure laws are followed.
Top Priorities
The FBI focuses on several key areas to keep the country safe:
- Protecting the U.S. from terrorist attacks.
- Stopping foreign spies and cyber attacks.
- Fighting serious cybercrime.
- Stopping corruption in government.
- Protecting people's civil rights.
- Fighting large criminal groups.
- Stopping major financial crimes.
- Fighting serious violent crime.
How the FBI is Funded
In 2019, the FBI's budget was about $9.6 billion. For 2021, they asked for about $9.8 billion. Most of this money is used for salaries and other expenses.
History of the FBI
Early Days
Before the FBI, there was a group called the National Bureau of Criminal Identification. It helped police find criminals. In 1901, after President William McKinley was killed, there was a feeling that the U.S. needed more ways to track threats.
President Theodore Roosevelt asked the Attorney General, Charles Bonaparte, to create a new investigative service. This service would report directly to the Attorney General. In 1908, Congress stopped the Justice Department from using Secret Service employees. So, Bonaparte decided to create a new agency with its own agents.
Creating the BOI
The Bureau of Investigation (BOI) started on July 26, 1908. Attorney General Bonaparte hired 34 people for this new agency. Some of them were from the Secret Service. Stanley Finch was the first "chief" of the BOI.
One of the BOI's first jobs was to help enforce the "White Slave Traffic Act" (Mann Act) of 1910. In 1932, the BOI was renamed the United States Bureau of Investigation.
Becoming the FBI
In 1933, the BOI joined with another agency and was called the Division of Investigation (DOI). Then, in 1935, it became its own independent agency. That same year, its name officially changed to the Federal Bureau of Investigation (FBI).
J. Edgar Hoover's Time as Director

J. Edgar Hoover was the FBI director for a very long time, from 1924 to 1972. He helped create the FBI Laboratory in 1932. This lab helped make investigations more professional. After Hoover passed away, a law was made to limit future FBI directors to a ten-year term.
During the 1930s, the FBI caught or stopped many famous criminals. These included John Dillinger and "Baby Face" Nelson. The FBI also looked into groups like the Ku Klux Klan.
The FBI started using wiretapping in the 1920s to catch people breaking laws. Over time, laws about wiretapping changed. Now, the FBI needs a warrant to tap phones during investigations.
Protecting National Security
From the 1940s to the 1970s, the FBI investigated cases of espionage, which is spying against the U.S. They arrested Nazi agents who planned attacks. They also worked on the "Venona Project" with the UK. This project broke secret Soviet codes. It helped find Soviet spies in the U.S.
Japanese American Internment
In 1939, the FBI started a list of people who might be taken into custody if the U.S. went to war. Many Japanese Americans were on this list. After the attack on Pearl Harbor in 1941, many Japanese American men were taken into FBI custody.
President Franklin Roosevelt then ordered the removal of Japanese Americans from the West Coast. FBI Director Hoover did not agree with this mass removal. But the order went through. The FBI continued to watch Japanese Americans during the war. After the war, the FBI helped protect returning Japanese Americans.
Civil Rights Movement
In the 1950s and 1960s, the FBI watched civil rights leaders. They were concerned about their influence. The FBI had a program called COINTELPRO. It investigated and tried to disrupt political groups in the U.S. One target was the Southern Christian Leadership Conference, led by Rev. Dr. Martin Luther King Jr..
The FBI often investigated King. King criticized the FBI for not doing enough about white supremacist violence. Hoover publicly called King a "notorious liar." Some reports say the FBI sent King anonymous letters. These letters tried to make him feel bad.
In 1971, a group broke into an FBI office in Pennsylvania. They took files and shared them with newspapers. These files showed the FBI's COINTELPRO program. It included investigations into regular citizens. These revelations surprised the country.
Kennedy's Death Investigation
When President John F. Kennedy was killed, the FBI was asked to take over the investigation. In 1965, a law was passed. It made sure the FBI would investigate the deaths of federal officials.
Fighting Organized Crime

In 1953, the FBI started the Top Hoodlum Program. This program gathered information on large criminal groups. The Racketeer Influenced and Corrupt Organizations Act (RICO Act) helped the FBI fight these groups. The FBI worked undercover to break up many of these organizations. They still use the RICO Act today.
Special FBI Teams
In 1982, the FBI created a special unit called the Hostage Rescue Team (HRT). This team helps with serious situations, like terrorism. It acts like a special FBI SWAT team. In 1984, the Computer Analysis and Response Team (CART) was also formed.
From the late 1980s to the early 1990s, the FBI focused more on violent crime. They helped local police track criminals who crossed state lines. The FBI Laboratory also helped develop DNA testing.
Important Efforts in the 1990s
In 1992, FBI SWAT and HRT helped keep peace during the 1992 Los Angeles riots. From 1993 to 1996, the FBI increased its role in fighting terrorism. This was after the 1993 World Trade Center bombing and the 1995 Oklahoma City bombing. The FBI's technology and lab skills helped solve these cases.
During the 1996 Summer Olympics in Atlanta, the FBI investigated a bombing. They were criticized for how they handled the investigation. They settled a dispute with Richard Jewell, who was wrongly suspected.
The FBI also upgraded its technology in 1998. They created new centers to deal with Internet problems. These included computer viruses and other harmful programs. The FBI increased its electronic surveillance to adapt to new technology.
After bombings in Kenya and Tanzania in 1998, the FBI made counterterrorism a top priority. They created a system to rank investigations. Counterterrorism and national security were the highest priority. After the September 11 attacks, more agents were assigned to terrorism cases.
After September 11 Attacks
During the September 11 attacks in 2001, FBI agent Leonard W. Hatton Jr. was killed helping people escape. After the attacks, FBI Director Robert Mueller changed how the FBI worked. He made preventing terrorism a top priority.
In 2001, a high-ranking FBI agent named Robert Hanssen was caught selling secrets to Russia. He was a spy for many years. This made people question the FBI's security.
A report in 2004 said the FBI and CIA were partly to blame for not stopping the September 11 attacks. The report said the agencies needed to change. The FBI made some changes, but some people felt they were not enough. A book in 2007 said the FBI and CIA missed many chances to stop the attacks. It said the FBI's structure made it hard for different offices to work together.
Technology and Information Sharing
In 2012, the FBI created the National Domestic Communications Assistance Center. This center helps law enforcement use technology for investigations.
The FBI also has a system called eGuardian. It started in 2009. This system helps the FBI share tips about possible terror threats with local police. It allows quick sharing of information about suspicious activities.
How the FBI is Organized
The FBI has different branches and offices. Each branch has an executive assistant director. These branches are divided into divisions, led by assistant directors.
The main branches of the FBI are:
- FBI Intelligence Branch
- FBI National Security Branch
- FBI Criminal, Cyber, Response, and Services Branch
