A new report from Amnesty International has revealed that Native American women are more than two-and-a-half times more likely to be raped or sexually assaulted than women in the United States in general. Studies show that one in three Native American women will be raped during their lifetime. Amnesty said many rape cases are never prosecuted because there is confusion regarding tribal and county jurisdiction. It is estimated that 86 percent of rapes against Native women are committed by non-Native men, but tribal councils have no jurisdiction over non-Native offenders even if the crime takes place on tribal lands.
