The Man Who Knew Too Much:
There are several problems with this story. First, Richard Case Nagell had serious credibility issues. Over the years, he repeatedly claimed to have secret evidence regarding the assassination, and nothing ever turned up.

Third, Jim Garrison himself has a very different story about Nagell and the Shaw trial in his book
