1) They used ground breaking radar, not soil analysis. That doesn’t even make sense.
2) It was already known before this that indigenous children were dying in the residential schools at a much higher rate than their white counterparts. Abuse of all kind was rampant and illnesses went untreated. Canada had a study on this.
3) Courts in North America aren’t making rulings that are binding on courts in Europe. That’s fucking ridiculous and native Europeans haven’t been abused by a government set up by those non Europeans like First Nations/Native Americans have.
