I am supremely confused by the involvement of the FBI in the first place. I broadly appreciate that a Civil War cache of gold would initiate something like “an archaeological excavation to recover government property”. I can understand having law enforcement presence during the dig due to the high value of the property, and if I really stretch I guess the FBI are essentially the federal government’s police force? So maybe that could be the explanation for why they were involved, but I’m still dubious on that. Even then, why they would carry out their own archaeological dig? And why they would document it so poorly, and finally why would they redact their documentation so severely afterward?
