I never knew public nudity is legal in San Francisco. The one exception is if you are aroused. If you are a man you could probably plea bargain that it was just a piss hard on and will pass with a potty break. The bigger question is how can you determine if a female nudist is aroused? Erect nipples may just be the product of a stiff wind, and the stain left behind on a chair may be just a monthly discharge. This unsanitary condition has led to the barrier proposal. Basically nudists would have to provide a protective barrier when they place their genitals and anus on a public bench, chair, or in restaurants. Well I certainly support that proposition, but what took them so long? California has some of the strictest regulations concerning pollution, sanitation, waste removal, and are only now confronting the bacterial contamination by their own residents. They are also requiring that nudists who testify at City Hall must cover up. The one chance they could get people to freely volunteer for jury duty and they blew it.
