I am also starting to think that maybe there is no gold in the US or at least not as much as they claim to be. Otherwise, why not to show the exact figures?
There is a "hidden" amount of gold owned by the US in fort knox, I would support the government releasing data on this. However being able to say how much gold is in the US and owned by private citizens would require people to "register" their gold which could lead to taking of gold which I would be against.
