(The film “Executive Action” laid it out in simple detail how easy it would be)
I remember that movie well. Grandpa Walton gave the go-ahead to take JFK out.
I think that film is very close to the mechanism of HOW the assassination came to be. The details maybe, maybe not. But HOW oligarchs and CIA decided and arranged it.
How and why the assassins felt safe to proceed and leave the country afterwards.
And how the oligarchs only connection to the killers was one man who could be eliminated afterwards. You could peel the skin off the assassins and they couldn’t tell you who set it in motion. Same for the oligarchs who had no idea who the shooters were.
Very compartmented and plausible.
