Gee,There not very peaceful...
From the article:
The angry demonstration began about 4:40 p.m. when a group of demonstrators beating drums and waving black-and-red flags blocked traffic at Fifth and Mission streets.
The mostly young activists, some with handkerchiefs covering their mouths and noses, turned onto Market Street, followed by police on bicycles.
The protest escalated to vandalism as the group turned up Sansome Street, spray-painting anti-war messages on the Citicorp Building.
Demonstrators used news racks and iron bars to smash a glass door at the Immigration and Naturalization Service building. As police rushed forward to protect the entry, the march turned south on Battery, smashing a window in a Starbucks coffee shop.
