If you haven’t watched the documentary, I highly, highly recommend it to gain some more perspective and insights as to how far they go to cover this up. 

 I read the ever best book about it: https://www.amazon.com/JFK-Vietnam-Plot-Assassinate-Kennedy/dp/1616082917

But I will watch this documentary too. 

 They cover how Oliver Stones work is that of the CIA, too. 😉
