The Emergency Detention Act, Title II of the Internal Security Act of 1950, is the only law in American history to legalize preventive detention. It restricted the freedom of a certain individual or a group of individuals based on actions that may be taken that would threaten the security of a nation or of a particular area. Yet the Act was never enforced before it was repealed in 1971.
