“Once a government is committed to the principle of silencing the voice of opposition, it has only one way to go, and that is down the path of increasingly repressive measures, until it becomes a source of terror to all its citizens and creates a country where everyone lives in fear. …
Everyone in public life has a responsibility to conduct himself so as to reinforce and not undermine our internal security and our basic freedoms. Our press and radio have the same responsibility. Private groups of all kinds, and citizens in their daily work and in their homes, are equally concerned with the question of protecting our liberties and our national security. We must all act soberly and carefully, in keeping with our great traditions. This is important not only to our own country, but to the success of the cause of freedom in the world.“
– President Harry S. Truman, August 8, 1950
