I have been researching this case since 1974, though it is a hobby that I delve into once every few months now.
I read a lot of books and I read, a few years ago, a well researched book called:
Ultimate Sacrifice: John and Robert Kennedy, the Plan for a Coup in Cuba, and the Murder of JFK
I know we all tire about the Castro-Cuba connection but this book tipped the scales for me, even though, I was already in the conspiracy camp.
I'm coming from the school where you look at the actual evidence and not the stories that conspiracy books tell you about the evidence. What is supposed to happen in 2037? Releasing documents? Aren't you aware that this already happened?
Ultimate Sacrifice is just another conspiracy book like 1,000 others. It gets a lot of stuff wrong and builds an argument on shaky and incorrect facts.
