(AP) — The court-ordered release of a trove of government photos, videos, maps and other documents involving the FBI’s secretive search for Civil War-era gold has a treasure hunter more convinced than ever of a coverup — and just as determined to prove it. “We have compelling evidence a night dig took place, and that the FBI went to some large effort to cover up that night dig,” said Getler, co-author of “Rebel Gold,” a book exploring the possibility of buried Civil War-era caches of gold and silver. The records released so far “cast doubt on the FBI’s claim to have found nothing and raise serious and troubling questions about the FBI’s conduct during the dig and in this litigation, where it has gone to great lengths to distort critical evidence,” Anne Weismann, a lawyer for Finders Keepers, wrote in a legal filing that seeks records, including the FBI’s operational plan, that she says were improperly withheld
