What does FBI mean? It represents the U.S. government? Just like the title. Thank you.

The Federal Bureau of Investigation, the full English name is Federal Bureau of Investigation, the English abbreviation is FBI, and the Chinese abbreviation is FBI. FBI Overview The FBI is the main investigative tool of the U.S. Department of Justice. According to Section 533 of Article 28 of the United States Code, it authorizes the Attorney General to "appoint officials to detect crimes against the United States." In addition, other federal laws give the FBI the authority and responsibility to investigate specific crime. The FBI currently has investigative jurisdiction over more than 200 federal crimes. The list of the Ten Most Wanted Fugitives has been publicized since 1930. The FBI's mission is to investigate violations of federal criminal laws and support the law. Protects U.S. investigations of foreign intelligence and terrorist activities and provides leadership and law enforcement assistance to federal, state, local, and international agencies while performing duties responsive to public needs and true to the Constitution of the United States. After each FBI investigation, intelligence information is submitted to the appropriate U.S. attorney or U.S. Department of Justice official, who will decide whether to approve prosecution or other actions. Five areas that impact society receive the highest priority: counteratrocity, narcotics/organized crime, foreign counterintelligence, violent crime, and white-collar crime. The FBI has a shady history of supporting the law and sometimes undermining it. But in the common impression of most Americans, it is the most effective agency in fighting crime. The number of dedicated agents has grown every year and now exceeds 11,000 members. Most specialized agents are stationed in foreign countries and work in U.S. embassies as ambassadorial legal attachés. The FBI calls itself "LEGATS." FBI History During the term of U.S. President Theodore Roosevelt, Attorney General Charles Joseph Bonaparte established the FBI composed of specialized agents on July 26, 1908. Initially called the Bureau of Investigation (BOI), it was changed to the Federal Bureau of Investigation in 1935. John Edgar Hoover became Director of the Bureau of Investigation on May 10, 1924. At the time, the Bureau spent considerable effort investigating political radicals who had committed no crimes (e.g., socialist Albert Einstein). While Franklin Delano Roosevelt was in office, it was not a crime to remind Hoover of liberalism, but the politics of the current president and administration. The FBI Scientific Detection Crime Laboratory (commonly known as the FBI Crime Lab) was officially established on November 24, 1932. In the 1930s, the FBI arrested a group of notorious kidnappers, robbers, and murderers such as John Dillinger, "Baby Face" Nelson, Kate "Ma" Barker, Alvin Karpis, and George "Machine Gun" Kelly. The FBI also played an important role in the campaign against the Ku Klux Klan. From the 1940s to the 1970s, the FBI investigated espionage cases against the United States. During World War II, the FBI captured eight Nazi spies who came to the United States to perform sabotage missions. The FBI has also done a lot of work against organized crime in the United States, cracking down on many criminal organizations and groups, such as the Sam Giancana family and the John Gotti family. In the 1950s and 1960s, the FBI conducted the controversial Operation Cointelpro. The operation was to investigate and impede the actions of dissident organizations in the United States. These organizations include military organizations, nonviolent organizations, and civil rights organizations. Hoover's investigation into Martin Luther King Jr. was also infamous - the FBI found no evidence of a crime and attempted to blackmail him using tapes of his private sex life. The Washington Post claimed that the FBI sent at least one anonymous letter to Martin Luther King Jr. urging him to commit suicide. In the 1990s, it was shown that the FBI's scientific criminal detection laboratory often made stupid mistakes. In some cases where the evidence originally exonerated the suspects, technicians reported that they were guilty. When such errors are discovered, many of these cases are reopened. Composition of the FBI The director of the FBI is appointed by the president and confirmed by the Senate for a 10-year term. The first director was Hoover and the current director is Robert Mueller. The bureau has more than 20,000 staff, of which more than 8,600 are field staff. The annual budget is $2.3 billion.

Subsidiary agencies of the FBI The FBI is headquartered in Washington, DC, and has 10 functional departments led by the Assistant Director, responsible for identification, training, criminal investigation, technical services, etc., and has set up field offices and offices in 59 cities across the country. There are more than 400 "local bureaus" affiliated with them, as well as overseas agencies located in 22 countries around the world, to carry out tasks assigned by the headquarters. There are criminal "scientific laboratories", a "central fingerprint archive" and an "academy" dedicated to training senior agents and police. The FBI National Academy is located at the U.S. Marine Corps Base in Quantico, Virginia. This advanced agent and espionage training institution, founded in 1972, is completely surrounded by 385 acres of forest, and it is difficult to see the panoramic view from the air. According to the FBI's official website, such an environment is conducive to "security and confidentiality." Remarkably, the U.S. Drug Enforcement Administration's training academy is also located nearby. The main body of the FBI National Academy includes 3 dormitories, 1 restaurant, 1 teaching building, 1 forensic research and training center, 1,000-seat auditorium, 1 chapel, 1 large gymnasium, 1 An outdoor track and a fully equipped auto repair shop. In addition, the National Academy also has a simulated city designed for actual combat simulations by FBI and Drug Enforcement Administration training academy trainees. There is also an indoor shooting range, 8 outdoor shooting ranges, 4 flying saucer shooting ranges and a 200-meter rifle submachine gun shooting range near SimCity.

Deportation of Chaplin: Chaplin became the subject of an FBI investigation for starring in films that addressed current abuses. In 1922, FBI agents infiltrated Chaplin's film studio as an undercover agent to monitor his every word and action. It didn't take long before an undercover agent reported to the director that there were "loud-talking Bolsheviks" and a large number of "radicals in the film industry." The topic of discussion was "how important it is for films to educate and promote the labor movement and revolution." . Burns was the director of the FBI at the time. After receiving the report, he immediately asked his subordinates to collect files on ideological trends in the film industry and list the radical activities in the film circle, especially "how to use movies as products." "socialist propaganda", trying to explain that because "films promote communist ideology", it will have an ideological impact on the people and must be closely monitored. Spying on Einstein: The FBI began spying on Einstein after World War II. The agents were alarmed by his endorsement of communist ideals and support for the civil rights movement, anti-war groups, and some socialist ideas. They were worried that such a well-known figure's criticism of U.S. policies would have a negative impact on society. The FBI created a detailed personal file on Einstein in order to find evidence that would lead to his deportation. The document is 1,424 pages long and records various aspects of the FBI's investigation into Einstein.
