A recently deceased friend was a young Navy SEAL in the early 60’s and was attached to the CIA during part of his service.
He told me that there were a group of retired servicemen in Florida that were part of the aborted Bay of Pigs invasion and that they got together every year to drink and play poker. This group was planning to airdrop into Cuba at various placed and disable the telecommunications and power grid. Obviously, they never got on the planes as Kennedy choked.
My friend said that the CIA killed Kennedy to let future Presidents know not to mess with the intelligence community.
He said that one member of his group wrote the real story and posted it on the internet.
Here it is:

Possible, given the fact the CIA was giving LSD to unsuspecting innocent Americans in the 1950s, while watching them do the chicken from behind two way mirrors in hotel rooms.
An organization that would do that, is likely capable of anything.
Not only did the president get his head blown off, but the cops in Dallas, while posing for cameras, stood and watched as the assassin get assassinated.
One thing is well known, there were many in and out of government who had the capacity and also wanted Kennedy dead.
The entire event reeked.
