Lance... yes, we shouldn't take ourselves or our theories too seriously... a real challenge for humans in general.
I think some of what drives my thinking on this subject, is knowing - or thinking I know - a little too much about some of the possible players on the stage, like LBJ and Hoover.
AND Arlen Specter's theory about the single bullet! Dang, look at the car Specter... Windshield is shot and the car molding... along with JFK and Connally... and the limo is whisked off the scene to be quickly repaired...
AND driver SS agent Bill Greer's rubbernecking and braking until the fatal shot!
AND Hoover's "exerting pressure" on his boys to quickly end their investigation and conclude that Oswald was the lone assassin...
Hoover, Greer, Specter... don't look in my face and lie to me! Yeah, that drives some of my thinking on this, too...
All right... peace!
One problem is that JFK was detested by such a diverse group of organizations and individuals, and so many stood to benefit from his demise, that weaving superficially plausible conspiracy theories is easy.
Then we factor in that most of the usual suspects - LBJ, Hoover, CIA, Mafia, etc. - were fully capable of ghastly deeds, in some cases up to and including assassinations and murders.
Then we factor in some huge motives - LBJ becomes President, Hoover isn't forced into retirement, the CIA has a friend in the White House, Castro is ousted, the heat is off the Mafia and their Cuban empire is restored, revenge is had for the Bay of Pigs, the oil depletion allowance survives, etc., etc.
It all starts to look, as it once did to me, like "How could this NOT have been a conspiracy??? OF COURSE, it was - the only issue is exactly who did it and how."
However, over my decades as a lawyer my conspiracy-prone mindset was gradually subordinated to the need for real evidence, reasonable inferences and critical thinking rather than Gee Whiz speculation and leaps of logic.
The more I studied and analyzed, the more the LN perspective made sense - not rock-solid sense, not a religious belief, but simply the most plausible explanation. If ever a conspiracy theory seems more plausible, I'll change my mind.
In many ways, the CT community is its own worst enemy. The wild diversity of theories, some of the most prominent being preposterous. The focus on anomalies and inconsistencies that in themselves go nowhere and that the CTers don't even attempt to fit into a coherent theory. The obsession with the WC as though its shortcomings were somehow proof of something. The absurd effort to play defense counsel for Oswald. The venom toward the LN position as though this were a religious debate (many of the LNers being equally guilty, of course).
If there were a single, reasonably evidence-based, reasonably plausible and coherent theory, one that at least generated interest among professional historians and journals, I and pretty much everyone else would listen and perhaps be swayed. As it is, the leading conspiracy exponents simply don't generate this sort of interest and strike most reasonable people, including me, as self-promoting cranks and hucksters.
