The United States Federal Bureau of Investigation, the full name of the Federal Bureau of Investigation, the United States Federal Bureau of Investigation in English and the United States Federal Bureau of Investigation in Chinese. The FBI concluded that the FBI is the main investigation method of the US Department of Justice. According to Article 28, Section 533 of the United States Code, the Attorney General is authorized to "appoint officials to investigate crimes against the United States", and other federal laws and regulations give the FBI the power and responsibility to investigate specific crimes. The existing investigation authority of the FBI has exceeded 200 federal crimes. The list of the top ten most wanted criminals has been made public since 1930. The task of the FBI is to investigate violations of federal crime laws and support the law. Protect the United States from investigating intelligence and terrorist activities from foreign countries, provide assistance to federal, state, local and international agencies in leadership and law enforcement, and perform their duties on the premise of responding to public needs and being loyal to the US Constitution. Every time the FBI investigates intelligence information, it will submit it to the appropriate American lawyers or officials of the US Department of Justice, who will decide whether to approve the prosecution or other actions. Among them, five aspects that affect society enjoy the highest priority: anti-atrocities, drugs/organized crime, foreign anti-espionage activities, violent crimes and white-collar crimes. The FBI once had a disgraceful history of supporting the law and sometimes even breaking it. But in the usual impression of most Americans, it is the most effective institution to fight crime. The number of agents is increasing every year, and now there are more than 1 1000 members. Most of the agents are stationed in foreign countries, working in the American embassy, and serving as the ambassador's legal commissioner. The FBI calls itself "LEGATS". The history of the US Federal Bureau of Investigation During President theodore roosevelt's tenure, the Attorney General Charles Joseph Bonaparte established the Federal Bureau of Investigation composed of special agents on July 26th. 1908. Originally known as the Bureau of Investigation (BOI), it was changed to the Federal Bureau of Investigation on 1935. John edgar hoover became the director of the Bureau of Investigation on May 1924. At that time, the Bureau of Investigation spent a lot of energy investigating political radicals who did not commit crimes (such as socialist Albert Einstein). When franklin delano roosevelt was in office, he reminded Hoover that liberalism is not a crime, but a political activity of the current president and the executive branch. The FBI Crime Lab (also known as the FBI Crime Lab) was formally established on June 24th, 2008 +0932+065438. In 1930s, the FBI arrested a number of notorious kidnappers, robbers and murderers, such as john dillinger, Nelson "Baby Face", Kate "Horse" Barker, Alvin Kapis and George Kelly? "Machine Gun". The FBI also played an important role in the action against the Klan. From the 1940 s to the 1970 s, the FBI investigated espionage cases against the United States. During World War II, the FBI captured eight Nazi spies who went to the United States to carry out sabotage missions. The FBI has also done a lot of work on organized crime in the United States, and cracked down on many criminal organizations and gangs, such as the Sam Giancana family and the John Gotti family. In the 1950s and 1960s, the FBI conducted the controversial Cointelpro operation. The content of this action is to investigate and hinder the actions of American dissident organizations. These organizations include military organizations, non-violent organizations and civil rights organizations. Hoover's investigation of Martin Luther King was also notorious-the FBI found no evidence of a crime and tried to blackmail him with tapes of his private life. Washington post claimed that the FBI had at least sent an anonymous letter to Martin Luther King, urging him to commit suicide. In the1990s, it showed that the scientific crime detection laboratory of the US Federal Bureau of Investigation often made low-level mistakes. In some cases, the original evidence shows that the suspects are innocent, and the technicians report that they are guilty. When such mistakes are discovered, many such cases will be retried. The composition of the FBI The director of the FBI is appointed by the President and approved by the Senate for a term of 65,438+00 years.

Fire Chaplin: Chaplin was targeted by the FBI for his performance in a film that criticized shortcomings. 1922, FBI agents sneaked into Chaplin's film studio to be undercover and monitor his words and deeds. After a while, undercover agents reported to the minister that there were "Bolsheviks who talked a lot" and a large number of "film activists". The topic of discussion is "How important movies are to educate and publicize the workers' movement and revolution". At that time, the director of the FBI was Burns. After receiving the report, he immediately asked his men to collect and sort out the files about the ideological trend in the film industry, and listed the radical activities in the film industry, especially "how to carry out * * * productive propaganda through movies", in an attempt to explain that "the productive thought of film propaganda * *" will have an ideological impact on the people and must be closely monitored.

This document is 1424 pages long and records the contents of the investigation of Einstein by the FBI.
