Meh computer fail. I quoted your top post without actually saying anything.
Going to be a little pedantic and respond. ... Just to clarify, I don't know what happened with JFK, every post/theory here could "possibly" be true from loan nutter fires 3 shots (ballistics has tested this and it is possible), to a small group engages LHO to shoot Kennedy to a larger CIA or KGB conspiracy was afoot. Were only dealing in degrees of likelihood, i.e. Will we see David Klemmer and Paps tackle hard for the Tigers, likely... will we see Nofa defend our line better then these two, unlikely based of past performance (Nofa, prove me wrong Buddy!) .
Yes a conspiracy theory is more "exciting", in JFK's case I also believe it more likely.
"The CIA would not collectively decide to murder their president." Have you read Brig General Smedley Butler's business plot?

I give this weight as, Smedley is actually testifying that this was told to him. (it isn't second or third hand). Butler is a General. I believe some in the USA would actually do this and 2022 doesn't contradict that.
We know the USA has been active in subverting elections overseas (as has Russia, Britain, etc. France as a colonial power was ruthless)... With Britain those lessons returned home, why not America?
1960's America is a different period of time, it's "Red's under beds"? Half of Hollywood was locked up by Joe McCarthy in his Terrorist style witch hunts... Hoover is vicious in arresting people and a lot of people thought Kennedy wasn't Anti-Communist enough!?
It doesn't have to be the entire CIA, someone like Guy Banister would have found a few loyal anti-communists to conduct the hit.
You are right, people would have to keep their lips sealed. A lot of people however have died in relation to Kennedy's assassination, was that to seal their lips??
We don't know and we won't know.
