In April, Amnesty USA issued a report on the denial of justice to Native American women who have been victims of sexual assault. Native American women suffer sexual assault at 2.5 times the rate of the general population, but due to the complex relationship between State, Federal and Tribal law a majority of sexual assaults cannot be or are not prosecuted. When sexual assaults occur on tribal lands, tribal authorities can only prosecute the offense if both the victim and perpetrator are members of that tribe. Tribal courts may not impose sentences longer than one year, significantly less than is usual for sex crimes convictions in other courts. However, 80% of victims describe their attackers as non-native. In those cases, crimes occurring on tribal land must be referred to federal authorities; a majority of such cases are never prosecuted. NPR’s All Things Considered reports several cases where Tribal law enforcement officers’ attempts to report such crimes to the US Attorneys were ignored by Federal authorities (the US Attorneys’ Offices declined to be interviewed for the report).
