In 1876 it was, for a time, debatable whether or not the Canadian government would allow Sitting Bull and his people to stay in Canada for any length of time, and the same was true when Chief Joseph and the Nez Perce headed north in 1878. No nation on Earth is innocent or even "Not Guilty" of doing bad things to their own or other people.
