And a newly declassified document from 1950 shows that former FBI director J. Edgar Hoover drafted a plan to suspend habeas corpus and imprison some 12,000 Americans he suspected of disloyalty. Hoover sent his plan to the White House in July, 1950, twelve days after the Korean War began. Hoover wanted the FBI to be able to permanently detain all individuals potentially dangerous to national security and jail them at military bases and in federal prisons. According to the New York Times, no known evidence suggests President Truman or any other president approved any part of Hoover’s proposal.
