Communities United Against Police Brutality is an all-volunteer organization of survivors of police brutality, family members of people hurt or killed by police, and allies.  Their goal is to provide a structure for survivors to regain their dignity and power, working together with others to bring police brutality to an end.  They operate a 24-hour hotline for police brutality cases, provide courtwatch and copwatch, and have achieved a number of important measures to increase police accountability, including a class action lawsuit that put cameras in all of the squad cars in Minneapolis.
