D. the US government to infringe on freedoms of the American people guaranteed in the Bill of Rights.
During the First Red Scare, which followed World War I, there was widespread fear of communism and radical leftism in the United States. This led to government actions that included arrests and deportations, often without due process, as well as violations of civil liberties. The Palmer Raids, for example, were a series of law enforcement actions led by Attorney General A. Mitchell Palmer that targeted suspected radical leftists, resulting in a significant infringement on individual rights.
