It's always good to think about what you'd do if your belief was falsified. Suppose that Ron Paul himself goes through every book, every record and every nook and cranny of Fort Knox personally with an electron microscope and announces he found only evidence that the Federal Reserve is and has been above-board with respect to the United States' gold holdings.

What would you do then? Would you actually say "Well, I guess my belief was wrong and I was misled by the people who promoted it to me", or would you find a way to move the goalpost and say that you'll continue believing until some other complex and politically-hard-to-manage thing happens? And then another, and then another?
