'The rate of violent crime among Native Americans is twice the national average; on some reservations, it's 20 times higher. At least one in three American Indian women will be raped in their lifetimes. Yet just 3,000 tribal and Bureau of Indian Affairs (BIA) officers—the only kinds of cops with jurisdiction on Indian land—patrol 56 million acres. In 2008, the Standing Rock Sioux Reservation in the Dakotas had nine officers for 9,000 people in an area twice the size of Delaware…Tribal courts can only prosecute misdemeanors such as petty theft and public intoxication. They can't issue sentences longer than one year without meeting special criteria, and even then, three years is the maximum. More serious crimes must be handled by federal prosecutors, who turn down 65 percent of the reservation cases referred to them.'
