The leader of a South Dakota tribe is expected to declare an emergency on the state’s largest Native American reservation because of rampant crime that he said hasn’t been curbed due to the U.S. government’s inadequate funding for law enforcement.

The state of emergency declaration planned for Saturday on the Pine Ridge Indian Reservation comes nearly six months after a federal judge ruled the U.S. government has a treaty obligation to support law enforcement on the reservation, but declined to determine whether the Oglala Sioux Tribe is entitled to the full funding amount requested.
