Check out Penal Code 415:
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.
Is it just me, or do (2) and (3) sound unconstitutionally vague?
