Have you read the hundreds of pages of first-person accounts of severe abuse in the voluminous Canadian government report on the matter? I have. Do you think they are all manufactured? Seriously?

As to reports of bodies not being in the unmarked graves that have been found, how do you suppose that the First Nations who uncovered the graves with ground penetrating radar identified them as graves? If you deny reports that the radar uncovered piles of bones, I don't know what to tell you except that conspiracy theories on the internet are a dime a dozen.
