A cosplay photo shoot held on the public Seacliff State Beach in Monterey Bay, California prompted a warning from the Santa Cruz Sheriff’s Office. According to local news station KRON4, the photo shoot involved a very large replica rifle that, based on footage shared by the news agency, didn’t feature any sort of markers to indicate that it was fake.

The incident took place on July 3, according to KRON, and involved a police response after concerned beachgoers reported sightings of the fake rifle. Regardless of whether they suspect it is real or fake, the Santa Cruz Sheriff’s Office encourages the public to report the presence of any firearm spotted in public.

Speaking to the news agency, a Sheriff’s Office official warned that carrying a replica gun in public, such as for a cosplay photoshoot, may put people at risk. ‘They may know it’s a replica,’ a Sheriff’s Deputy explained. ‘but our responding officers don’t have any idea what they’re walking into, as well as the other public members that are on the beach.’

Regulations for displaying replica or imitation firearms in public vary based on jurisdiction. In California, imitation firearms are prohibited from display in public places unless they are entirely painted with certain approved bright colors or are entirely transparent. Violating these rules may result in fines for the first and second infractions potentially followed by a misdemeanor for any future violations.
