9.08.070 Masks and disguises.

It is unlawful for any person in the city to appear in public in any mask, cap, cowl, hood or other thing concealing the identity of the wearer; excepting, however, persons attending or taking part in carnivals conducted in accordance with law or under permission of the proper authorities of the city and persons holding a written permit to so conceal their identity, which permit is issued by the Chief of Police. (Prior code § 3-4.06)

Imagine a person who carries a written permit from the Chief of Police to conceal their identity. Fascinating!

But I have tried your patience long enough, gentlefolk, and so I leave you for the evening with the invitation to peruse at your leisure the fantastic convolutions of the Oakland Municipal Code.
