John Marshall Harlan II,
Noto v. United States — Opinion of the Court
“ There must be some substantial direct or circumstantial evidence of a call to violence now or in the future which is both sufficiently strong and sufficiently pervasive to lend color to the otherwise ambiguous theoretical material regarding Communist Party teaching, and to justify the inference that such a call to violence may fairly be imputed to the Party as a whole, and not merely to some narrow segment of it. ”
