The Tenderloin is a high-crime neighborhood, particularly violent street crime such as robbery and aggravated assault. Seven of the top 10 violent crime plots (out of 665 in the entire city as measured by the San Francisco Police Department) are adjacent plots in the Tenderloin and Sixth and Market area. The neighborhood was considered to be the origin of a notorious Bahala Na Gang (BNG) imported from the Philippines. In the late 1960s to the mid-1970s, the gang was involved in extortion, drug sales, and murder for hire.
