In the 1950's false accusation of Communist sympathies

b. led to the McCarran Act.

Explanation:

The McCarran Internal Security Act (or Subversive Control Act) of 1950 was enacted to check the activities of Communist sympathizers.  The law required all suspected subversive groups to register with the US Attorney General office. This law was the response by Congress to the likely existence of an International Communist Conspiracy, which it regarded as posing a clear and present danger to the US.  The fear of communism caused the US Congress to veto President Truman to pass the law.  However, it threatened the citizens' first amendment rights of freedom of speech and association.
