On December 15, 1890, Sioux Chief Sitting Bull was killed by the Indian police on the Standing Rock Reservation in South Dakota. Sitting Bull felt deeply that the Sioux Indians needed to be left on their own to follow their traditional practices, and his tactics were to resist not to respond with aggression. Unfortunately, Indian agents felt Sitting Bull was plotting an uprising so they ordered the Indian police to bring him in. Though they intended to bring Sitting Bull in quietly, the police still caused chaos and a Sioux took a shot at the arresting officers. They responded by killing the unarmed Sitting Bull who had been pulled out of his bed at 6 a.m. for the arrest.
