Hugo Black Quote
The First Amendment's language leaves no room for inference that abridgments of speech and press can be made just because they are slight. That Amendment provides, in simple words, that "Congress shall make no law... abridging the freedom of speech, or of the press." I read "no law... abridging" to mean no law abridging.
Concurring opinion, Smith v. California, 361 U.S. 147 (1959).
