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. 😉
