You are full of shit. When Indians killed other Indians we let them work it out. When Indians killed an American the federal government prosecuted them.
The
Major Crimes Act of 1885 or (
18 U.S.C. § 1153), enacted as section 9 of the Indian Appropriations Act, 1886, Major_Crimes_Act Original Statute-is a law passed by the
United States Congress. The law places certain crimes under federal jurisdiction if they are committed by a
Native American in
Native territory. The law follows the
1817 General Crimes Act,a which extended federal jurisdiction to crimes committed in Native territory but did not cover crimes committed by Native Americans against Native Americans.
