    The crime of disturbing the peace is defined in section 415 of the California Penal Code. Any of the following persons shall be punished by imprisonment in the county jail for a period of not more than 90 days, a fine of not more than four hundred dollars ($400), or both such imprisonment and fine:

    (1) Any person who unlawfully fights in a public place or challenges another person in a public place to fight.

    (2) Any person who maliciously and willfully disturbs another person by loud and unreasonable noise.

    (3) Any person who uses offensive words in a public place which are inherently likely to provoke an immediate violent reaction.92

    Fighting Words

    Although the First Amendment protects peaceful speech and assembly, if speech creates a clear and present danger to the public, it can be regulated. Schenck v. U.S., 249 U.S. 47 (1919). This includes fighting words, or “those [words] which by their very utterance inflict injury or tend to incite an immediate breach of the peace.” See Chaplinsky v. New Hampshire, 315 U.S 568, 572 (1942).

    Any criminal statute prohibiting fighting words must be narrowly tailored and focus on imminent rather than future harm. Modern US Supreme Court decisions indicate a tendency to favor freedom of speech over the government’s interest in regulating fighting words, and many fighting words statutes have been deemed unconstitutional under the First Amendment or void for vagueness and overbreadth under the Fifth Amendment and Fourteenth Amendment due process clause.93
