San Francisco police warn against attending the Dolores Park hill bomb skateboarding event due to potential arrests, vandalism, and violence.

San Francisco police warn against attending the annual Dolores Park hill bomb skateboarding event due to potential arrests, vandalism, and violence. Last year, 113 arrests and citations occurred; this year, the department plans to deploy extra officers and install barricades to prevent the event. Skater activists propose a "harm reduction plan" with safety measures, but city officials have not indicated support.
