More Arrests in SF Protests

Protesters are still on the march in San Francisco. Police cordoned off at least 200 people at one intersection last night and announced that everyone was under arrest. Some people said they were on their way somewhere else and just got caught up in the crowd. A police spokesman says one officer was injured in a confrontation with protesters and taken to a hospital for observation. An estimated 900 people were arrested in San Francisco Friday, on top of more than 1,300 arrested Thursday.
