In 2000, police in the city of Oakland, California became a symbol of the worst of American law enforcement after a band of rogue officers known as "The Riders" were accused of beating suspects, planting evidence and falsifying reports.

Today, as an outcry over police killings and excessive force radiates across the country, Oakland's police are becoming known for something quite different: restraint and reform.

Under scrutiny by a court-ordered external monitor and threatened with federal receivership, Oakland's 14-year journey from notorious law enforcement agency to reform-minded department illustrates the difficulty of changing the way police operate at time of national soul-searching over heavy handed police tactics.
