Hoover planned to jail 12,000 people for 'disloyalty'

The Sydney Morning Herald reports that recently declassified documents show that former FBI Director J Edgar Hoover submitted a plan to the White House, 12 days after the Korean war began, to suspend habeas corpus and arrest 12,000 people whom he suspected of disloyalty, and put them in 'permanent detention' in military prisons.

97% of the people on the list were American citizens.  The arrests were to be proclaimed by then-president Truman to be necessary to 'protect the country against treason, espionage and sabotage.'

Hoover obviously wasn't a big fan of the bill of rights.
