I have no idea what the tribes knew or did not know. Do you? I am amazed at some people's abilities to read other's minds.

As to the tribal leaders signing the documents. I can understand how the monetary promises given to them by the Canadian government would make them overlook the potential for atrocities yes; such things are well attested to in the history of humanity. But again, I have no idea. You asked me to speculate, so I did.

I don't understand why there is so much outrage today when one expresses that they do not know an unknowable fact.
