Fred M. Vinson,
American Communications Association v…
“ Although the First Amendment provides that Congress shall make no law abridging the freedom of speech, press or assembly, it has long been established that those freedoms themselves are dependent upon the power of constitutional government to survive. If it is to survive it must have power to protect itself against unlawful conduct and, under some circumstances, against incitements to commit unlawful acts. Freedom of speech thus does not comprehend the right to speak on any subject at any time. ”
