> How do you know this?
How do I know that they haven't done an archeological dig to validate the accuracy of their scans? Because they explicitly have said so. Indeed, they've said they may never, and I would wager will never.
I said nothing about the "lack" of analysis, I'm just saying that you, like so many others, are incredibly accepting about information flowing through multiple parties, some of whom have a strong incentive to lean a certain way. The deficiencies of ground penetrating radar is very well known -- it's a very powerful tool, but read the words of the technicians who did it compared to the tribe spokespeople. They talk about anomalies, and how they have tried to be careful in the language they use (specifically noting that they can't say something is a grave, just that the patterns look similar to "a grave shaft").
How many grave locations do you think the team that did this survey have done? Have many tests of their claims? How has the rigor of their claims been validated?
