On May 10, 1924, one of the worst events in history for American civil liberties happened: 29-year-old J. Edgar Hoover assumed the role of director of the then-Bureau of Investigation. Ambitious, power-hungry, and conniving, Hoover epitomized the snake in the proverbial garden. Under his watch, which lasted until his death in 1972, the FBI emerged as an alarming adversary to constitutional freedoms.
Starting his career at the Justice Department in 1917 at only 22 years old, Hoover quickly ascended the ranks, often at the expense of Americans' civil liberties. By 1919, he headed the Justice Department's Radical Division, charged with destroying the supposed communist infiltration of America. Hoover's lifelong disdain for communists was matched only by his disregard for their constitutional rights, making this role a perfect fit for his ambitions.
