Bill Cody tried to protect them, and he was a professional hunter, and a white man, but the government felt otherwise, as it would have taken away the primary source of food for the Natives... also, just 1 tribe, the Commanche tribe, was killing around 280,000 Bison a year.. thats just 1 tribe... im not saying that what we did 200 years ago was right, im saying, its not just our fault... as far as Eagles, they were endangered for a reason, why would you want to put them in any situation remotely the same as that?
