Throughout the 19th Century the U.S. Cavalry perpetrated the genocide of Indian People. Today’s Cavalry–federal, state and local police–are no longer committed to extermination. But American cops’ flagrant disregard for tribal self-governance when carrying out law enforcement activities on Indian lands, threatens the existence of Indian People.
Thankfully Indian inherent sovereignty and treaty rights can halt non-tribal cops who encroach upon Indian country under the guise of the Major Crimes Act or Nevada v. Hicks and while doing so, threaten tribal territorial autonomy and Indian civil rights.
