Well you could ask the David Archambault's sister why this big mess cam about. Jodi Archambault Gillette was the Special Assistant to the president for Native Affairs until she resigned in late 2015, just before construction started by Standing Rock. http://www.sonosky.com/attorneys-Jodi-Gillette.html. If only the tribe had a voice inside the White House, someone to call before all this started. It never has been about the water or ancestral grounds. But those were the magic phrases to get outsiders to show up and join the cause.
