Our group of people, of all ages, protested the San Diego curfew back in 1997. Here is a documentary about the protests and our tactics. I still support using the first amendment as a defense against the curfew. Meaning, you would state you are engaged in free speech by wearing a sticker, or peaceably assembling, or writing a story as a journalist and claiming the freedom of the press. However, we now feel it’s better to challenge the jurisdiction of the police, the city government, and the courts (actually banks). This is complex but much more powerful and will help in many other areas of life. Note this is not legal advice. Just details about what I might do. Notice that you are responsible for your actions. More details are here.
