J. Edgar Hoover
Directer of the FBI
FBI- Marcus Garvey
Advancing from assistant in 1921 to director of the Bureau of Investigation in 1924, Hoover emphasized modern technological investigative techniques, improved training, and obtained increased funding from Congress for the organization. During the 1930s, F.B.I. exploits against notorious gangsters, particularly John Dillinger, made Hoover a national hero. A string of high-profile gang arrests by the Bureau led to an expansion of power for the organization, and the Bureau became the Federal Bureau of Investigation in 1935.
Hoover against Martin Luther King Jr.
Hoover was renowned for his vendettas, particularly against Martin Luther King, Jr. Naming him "the most dangerous Negro in the future of this nation," Hoover used cointelpro to initiate around the clock surveillance on King, hoping to find evidence of communism or sexual deviance. Using an illegal wiretap, Hoover was convinced he had proof of King's infidelitous behavior, and attempted to push reporters into publicizing the recording. The media refused. Instead, Hoover sent the tape directly to King's office, suggesting he commit suicide or face exposure.
