Did the city of San Francisco declare war on Iraq?

I think everyone has a right to protest, but I'm not sure they have a right to step in front of my car when I'm on my way to work. If people want to call attention to peace, why do they need to disrupt the entire city? Some of the people hindered by this were probably on your side, and might have come out to join you, except that they had to go to work, or take their kids to school, or go to the doctor.
