EXCERPTS FROM THE MCCARRAN INTERNAL SECURITY ACT (1950)
To protect the United States against certain
un-American and subversive activities by requiring registration of Communist
organizations, and for other purposes.
SEC. 2. As a result of evidence adduced before various committees of the Senate and House of Representatives, the Congress hereby finds that-
(1) There exists a world Communist movement which, in its origins, its development, and its present practice, is a world-wide revolutionary movement whose purpose it is, by treachery, deceit, infiltration into other groups (governmental and otherwise), espionage, sabotage, terrorism, and any other means deemed necessary, to establish a Communist totalitarian dictatorship in the countries throughout the world through the medium of a world-wide Communist organization. . . .
(4) The direction and control of the world Communist movement is vested in and exercised by the Communist dictatorship of a foreign country. . . .
(15) The Communist movement in the United States is an organization numbering thousands of adherents, rigidly and ruthlessly disciplined. Awaiting and seeking to advance a moment when the United States may be so far extended by foreign engagements, so far divided in counsel, or so far in industrial or financial straits, that overthrow of the Government of the United States by force and violence may seem possible of achievement, it seeks converts far and wide by an extensive system of schooling and indoctrination. Such preparations by Communist organizations in other countries have aided in supplanting existing governments. The Communist organization in the United States, pursuing its stated objectives, the recent successes of Communist methods in other countries, and the nature and control of the world Communist movement itself, present a clear and present danger to the security of the United States and to the existence of free American institutions, and make it necessary that Congress, in order to provide for the common defense, to preserve the sovereignty of the United States as an independent nation, and to guarantee to each State a republican form of government, enact appropriate legislation recognizing the existence of such World-wide conspiracy and design to prevent it from accomplishing its purpose in the United States. . . .
SEC. 4. (a) It shall be unlawful for any person knowingly
to combine, conspire, or agree with any other person to perform any act which
would substantially contribute to the establishment within the United States of
a totalitarian dictatorship, as defined in paragraph (15) of section 3 of this
title, the direction and control of which is to be vested in, or exercised by
or under the domination or control of, any foreign government, foreign
organization, or foreign individual: Provided, however, That this subsection
shall not apply to the proposal of a constitutional amendment. . . .
(f) Neither the holding of office nor membership in any Communist organization by any person shall constitute per se a violation of subsection (a) or subsection (c) of this section or of any other criminal statute. The fact of the registration of any person under section 7 or 8 of this title as an officer or member of any Communist organization shall not be received in evidence against such person in any prosecution for any alleged violation of subsection (a) or subsection (c) of this section or for any alleged violation of any other criminal statute. . . .
SEC.7. (a) Each Communist-action organization (including any organization
required, by a final order or the Board, to register as a Communist-action organization)
shall, within the time specified in subsection (c) of this section, register
with the Attorney General, on a form prescribed by him by regulations, as a
