What we need is a suitable court case that can subpoena all evidence and extract sworn testimony from all witnesses. The general rule in any potential criminal investigation (such as the misuse of moon landing funds for a hoax) is to start at the bottom: with the evidence most likely to have escaped tampering or destruction, and the people least likely to commit perjury. Then work your way up, offering complete or partial immunity at one level in order to incriminate the next higher level.

Otherwise, future generations will treat the alleged moon landings the same way we treat the alleged discovery of America by St. Brendan the Navigator and his crew of altarboys.
