One of the better books on the Kennedy conspiracy was the Giancana son’s book, Double Cross (I think that’s the title). The mafia does mention way back then (during the GHWBush presidency) a Bush involvement, points or hints at it. At that time, I was shocked.
After what I’ve read about the true story of Mena, not as shocked.
Watch Narcos and Cocain Cowboys on Netflix/Amazon now - explains the Barry Seal, CIA, Escobar, Nicaragua connection very well. Our CIA really get’s around and portraid usually in an estranged relationship with the other alphabet agencies (e.g., FBI, DEA).
