Sure, I believe there is a reason that CIA-oriented conspiracy theories are the rage while more plausible ones, like the Mafia, get short shrift. The Morley-Newman-Di Eugenio wing of Conspiracy World epitomizes this. These are mostly extremely left-leaning characters who believe the country has gone to hell in a handbasket since the JFKA and that we'd be living in a near-utopia if JFK and RFK had lived. They have elevated JFK and RFK to near sainthood, even to the extent of imagining policies and accomplishments that simply aren't true. The theorizing almost works in reverse: the country has gone to hell since the JFKA, hence the Dark Evil Forces responsible for this "must" have been responsible for the JFKA. I think they are less interested in the JFKA as a historical event than as a validation of their worldview. Plus, of course, elaborate CIA-type theories are simply more fun than some mundane Mafia hit. The LN narrative, of course, is completely unacceptable since it explains and validates nothing.
I started a thread on this topic at the Ed Forum after I'd been a member only a short time because what I was observing was so screamingly obvious. Suffice it to say, it wasn't popular.
IMHO, it boils down to whether one hates / fears the "evil, evil, evil" CIA so much for employing "dirty, dirty" methods in its trying (since 1947 when it was formed) to fend off even more-evil Soviet Communism that one is willing to accept the idea that . . . gasp . . . GIVEN THE FACT THAT THE SBT THEORY IS A HOAX AND JFK'S HEAD "OBVIOUSLY" WAS SHOT FROM THE FRONT, ETC, ETC, ETC, OODLES AND GOBS of CIA bad guys and CIA bad gals MUST HAVE BEEN wittingly involved in the planning, the "patsy-ing," the shooting (and at least part of the FBI's / DPD's / Secret Service's egg-on-face CYA cover up)!!!
Regardless, thank God we can now sit back and relax and tell ourselves, "THE COLD WAR IS OVER, AND WE WON!!!," even though a "former" KGB officer / Russian Mafia Godfather did install our "President" in 2017 and 2025.
