On the same week members of the Confederated Salish and Kootenai Tribes were meeting with the U.S. Department of Justice and other law-enforcement agencies to hammer out protocols to address missing people on the reservation, the ABC series, “Big Sky” – a drama about missing women in Montana – sought to use tribal imagery without permission. The crime thriller debuted Nov. 17 and is based on a book by Wyoming author C.J. Box. The series, set in Montana and filmed in British Columbia, follows two women, a private detective and an ex-cop, who team up to search for two sisters who have been kidnapped by a truck driver on a remote highway. Along the way, they discover a spate of other abductions in the area.
