I don’t think you realize just how bad the situation is for indigenous women. Because of the complex bureaucracy surrounding reservations described in Public Law 280, authorities can’t even investigate indigenous women’s disappearances unless they know whether the perpetrator was indigenous or not (as this determines which agency has jurisdiction over the crime). This means that while there’s at least an investigation into other disappearing women, indigenous women often don’t get any at all. It’s a real issue and you should educate yourself before assuming the focus on indigenous women comes from nowhere at all. Seriously, read up on PL 280. this video is a good start
