In the 1960's, the CIA were engaging in dirty tricks of setting up soviet officers with prostitutes, then filming them in bed, and then threatening to show the footage to their wives if they did not pass on secret information to them.
It seems to me that if the CIA wanted to get rid of JFK, they would have just gone down this route. Film him in bed on one of his many escapades, and then release this footage to the press. This would have derailed his 1964 campaign, making it more likely the pro-war Richard Nixon would have been made president, and in this way the CIA/military industrial complex would get to continue and ramp up the Vietnam war.
So why would the CIA/military industrial complex go to all the complex trouble of assassinating JFK and setting up a patsy (i.e Oswald) and altering this autopsy footage/x-rays rather than simply film JFK in bed with someone and then release that to the press?
I don't think there is a good answer to that other than the CIA/military industrial complex had nothing to do with what happened in Dealey Plaza.
"They" were smarter than us and decided to shoot him in broad daylight in the middle of a crowded street with numerous people with cameras filming it.
Not only that: they decided to shoot him from in front and then collect all the material and alter it to make it look like he was shot from behind.
Then "they" assembled a collection of distinguished men - several with long careers in the law - to cover all of this up. Knowing that all would be quiet about their treason for the rest of their lives and that everyone otherwise involved would remain silent. Everyone from waitresses and cab drivers and shoe salesmen and warehouse workers and steamfitters to presidents. All would keep their secret.
Then "they" altered the Dominion voting machines. Oops, that's another conspiracy.
In conspiracy world everything looks simple and easy to do. "They" can do anything and everything. Plan it out, execute it, keep it quiet. Everything looks simple to do if you read conspiracy books.
It's nonsense, it's lunacy.
