during the 70s, after Nixon removed the gold standard, a television crew and some celebrities were invited to Fort Knox to witness that there is a lot of gold there
during the televised session, they only open up 1 vault full of gold to the cameras, the other vaults they never open......
that was in the 70s, now 2022 i think all empty already, when germany demanded their 675 tons of gold back, it took the US several years to return
