California Penal Code § 415. Disturbing the Peace
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
Disturbing the peace really doesnt apply here. No one is challenging anyone to a fight, no one would be making loud or unreasonable noise, and no one would be using offensive words. The chief is using this as a catch all to intimidate people for lawful behaviour. The violation of the fair policy is not a criminal act and is not an arrestable offense. If this was being held at a private venue the only thing I believe the police could do is ask you to leave, and then trespass you (PC 602) if you didnt comply. Since this is a public event, in a public venue they would have to find another PC to run you in on.
