JFK - Cowboy Hats And Rattlesnake Boots.
.
Where that 107 dude is? ;)

Yes, the "local enemies" ... do you know when they made the body switch ... was it after JFK had the assignation attempt in the car, then switched-out at the hospital, so they thought they had completed the coup? There was a SS agent or policeman that greatly resembled JFK, (given that nickname) who actually died in his place ... I saw a great video on the whole scenario, but not sure of the details now.

JFK did not die, Nana is convinced of it.
We also have had visitors from the future.
Convinced of that too.

agreed, ... "do you know when they made the body switch..."

No, do you?
It appeared that First Lady Jaqueline was aware tho.
She knew it was not him.
When they asked her about changing clothes she told them no they needed to see what it basically.
I think she knew it wasnt him, now was she still in shock from the impersonator being shot, most likely yes unless it was a clone.
I really dont have a feel for who or what the replacement was.

saw a detailed video and it claimed there was a person very similar to JFK ... but how did this double die (legal?) and how was he replaced? If so, then they knew about the plan ... too many if's so I just don't know what happened ... except that Oswald was definitely set up.

Have you watched "JFK to 911: Everything is a Rich Man's Trick"? Also, Phil Godlewski did a show on how it was done.
