Thanks to Dragon, I discovered that there is such a thing as the San Francisco Sheriff's Department and not just the San Francisco Police Department. The primary function of the SFSD is to operate the county jail system. The SFSD also provides security to the civil and criminal courts, and law enforcement services to San Francisco's landmark City Hall, and the City and County's Emergency Communications & Dispatch center, San Francisco General Hospital, Laguna Honda Hospital, and several public health clinics throughout the City and County. The Department also has a Special Response Team (SRT), who have been trained in Special Weapons And Tactics.
Dragon released this SFSD SRT figure "David Wong" in 2003
