Wacky SF at it again

I'm so glad I don't live in the City anymore.  My only question, as a parent, is why weren't these people arrested?  Last I heard, there were laws on the books against this type of display.  [By the way, do not click on that link if you're offended by pictures of really ugly people who get naked to make a political point.  Really.  I'm not kidding.  You are warned.]
