If you're wondering why Stanwich here is acting weird, it's a common right-wing conspiracy in Canada that these unmarked graves are "unproven" because they were discovered with ground-radar instead of dug up. They won't accept that there were deaths at these schools until they're dug up and the remains positively identified, at which point, one assumes, they'll accept that the attempt at cultural genocide that went on at these schools also had a side effect of mass graves.
