To go back to the original question...it depends on what side of the fence you're on. While a few JFK assassination CTs made a modest amount of money over a long period of time--Mark Lane, Anthony Summers, Davd Lifton, and Robert Grdoen come to mind--an equivalent or larger number of JFK assassination LNs have made serious money over a much shorter period of time. Think Gerald Posner, Mark Fuhrman, Bill O'Reilly, James Swanson, and, yes, even Vincent Bugliosi. While Bugliosi spent 20 years working on his doorstop, he was paid a large sum up front and another million or more for the film rights. Let's assume then it was a million for the book and a million for the film rights. 2 mil over 20 years is...100k a year That's far more than any CT received over the same time period.
But still probably less than O'Reilly received for a book he didn't even write.
O'Reilly, to me, is the litmus test. While one of the longest ongoing complaints among LNs is that JFK CTs are just trying to make money off the case, O'Reilly made millions off a book so bad not one prominent LN endorsed it--that he didn't even write--and yet not one prominent LN complained about this, not one. At least that I recall. (If anyone remembers the likes of McAdams, Holland, or Myers writing an article about
