Quizplus · Accepted Answer

President Truman vetoed the McCarran Internal Security Act in 1950 because he believed it would establish a "thought police" and violate the basic principles of American freedom. The act allowed for the investigation and detention of suspected subversives without the requirement of a trial, which Truman deemed a threat to civil liberties.
