On Sunday, NewsHour Weekend examines the inequality of criminal prosecutions on American Indian reservations, where women face some of the highest levels of violence. The Justice Department says acts of sexual assault against this group are most frequently committed by non-Indian men, who are generally immune to prosecution in tribal courts. Congress reauthorized the Violence Against Women Act last year, which effectively gave tribal courts jurisdiction over certain domestic violence crimes committed by non-Indians. But victims say acts of sexual violence on Indian reservations are still falling through the cracks. NewsHour Weekend's Stephen Fee reports. That, and the weekend's news, online and on-air.
