for those that don’t understand why that would be (other than blatant racism):
Federal courts have jurisdiction on Indian reservations under the Major Crimes Act passed in 1885. Ordinarily, states prosecute “street crimes,” including assault, burglary, sexual assault, murder and vehicular manslaughter.
Because of strict sentencing guidelines, with mandatory minimums and no probation or time off for good behavior, sentences in federal court generally are higher than those in state courts, at least in states including North Dakota, South Dakota and Montana [which have large American Indian populations].
so that’s why you see, as the article points out, an American Indian woman victim of abuse who struggled with documented depression & substance abuse, was convicted with a 10-year sentence for what two white women (who btw did not have documented mental health issues or experiences of abuse) did under 5 years for.
also please note which kinds of cases US attorneys are taking on; while there is substantive evidence that they are active in disproportionate incarceration of American Indian “perpetrators” (see Montana’s school-to-prison pipeline for another example of this), they are declining an alarmingly high number of cases with American Indian victims (particularly cases of sexual violence, which are overwhelmingly perpetrated by non-Indians, and in most cases, white men).
