0:00 On March eighth, 1971, a crowbar cracked the exterior door of a small suburban F.B.I.0:06 office in Media, Pennsylvania.0:08 Last week, we saw how William J.0:11 Burns was forced out in 1924, leaving behind a scandal-ridden Bureau of Investigation that desperately needed a clean start; that opening brought twenty-nine-year-old J.0:24 Edgar Hoover into the directorship.0:27 For the next forty-eight years, until his death in 1972, Hoover was the Bureau.0:33 He cast himself as the ultimate lawman—unimpeachable, methodical, and incorruptible.0:39 He built the Scientific Crime Detection Laboratory in 1932.0:44 He helped invent the Ten Most Wanted list in 1950.0:47 But that quiet night in Pennsylvania, inside file cabinets that Hoover thought no outsider would ever touch, a different reality was waiting.0:58 Eight anti-war activists slipped into the Media office while the country was distracted by the Ali-Frazier fight.1:07 They shoved over one thousand classified documents into suitcases and vanished into the dark.1:14 Hoover had spent half a century convincing the public that his agents were exclusively hunting kidnappers, mobsters, and bank robbers.1:24 The Media files told a radically different story.1:28 When the stolen records were analyzed, only one percent of the office’s workload concerned organized crime.1:36 Bank robberies, murder, and interstate theft took up about fifteen percent.1:42 A staggering forty percent of the documents detailed domestic political surveillance.1:49 Over two hundred left-wing and liberal groups were under active scrutiny, tracked not by high-tech spycraft, but by postal workers, switchboard operators, and campus informants.2:02 It was the first public rupture of COINTELPRO—Hoover's secret counter-intelligence program.2:09 Hoover’s obsession with dissent wasn’t a late-career slip; it was the foundation of his career.2:17 Long before the 1960s, Hoover turned the Bureau’s investigative power against political movements in Puerto Rico.2:25 Even before the Second World War, his agents spied on and harassed labor leaders, the Puerto Rican Communist Party, and the Pro-Independence Party.2:37 He used infiltration and legal pressure to keep the island tightly bound to mainland control.2:44 For Hoover, maintaining public order meant defining which ideas were permissible and which were dangerous.2:52 Then came the turn that shook Washington.2:55 The Media documents leaked to the press, and the mythology Hoover spent five decades manufacturing began to collapse under its own weight.3:06 Hoover moved swiftly, shutting down the centralized COINTELPRO and declaring that future counter-intelligence operations would be handled case by case.3:17 But the dam had broken.3:19 The Senate formed the Church Committee, exposing decades of illicit surveillance, break-ins, and smear campaigns directed from the very top.3:30 The tragedy of J.3:31 Edgar Hoover wasn’t that he failed as an investigator; it was that he succeeded so thoroughly at turning investigation into political power.3:42 After Hoover died in office in 1972, Congress passed legislation capping all future F.B.I.3:49 directors at a single ten-year term, determined that no single man would ever hold that kind of unilateral power again.3:58 Today, Hoover’s name still stands carved across the Bureau’s concrete headquarters in Washington, D.C.4:06 But the legacy inside those walls is divided: the pristine scientific crime lab on one side, and the unlocked file cabinet on the other.
