Pervasive alcoholism is among the main reasons tribal leaders ban the sale of alcohol on reservations. But that can be big business for liquor stores just outside of the border. Tribal leaders from the Pine Ridge Reservation are working to shut down four stores in nearby Whiteclay, Neb. They say the vast majority of their sales goes to worsen alcohol-related problems within Pine Ridge. Critics of the strategy say people wanting a drink will get alcohol somewhere else and might even increase the hazard by drinking and driving. Does banning alcohol on the reservation help the people or not?
