I think this is beyond the scope of what is possible and an unrealistic theory. I won't downvote you and am not morally opposed to your theory. I just think too many people would have to be in on it. I know people say that about every conspiracy theory, but the other team has swarms of operatives ready to detect something off. You need all the guys hauling out the bodies to be in on it, secret service (which is known to be compromised) to be in on it. You need youtube and google to be in on it judging from the way in which certain searches were recoded right after the event. Logistically, it is just not possible. I don't see it.

Trump got lucky. He isn't invincible. Similar to JFK, his hubris put him in danger. Even the way he jolted up, as heroic as it was, was lucky hubris. Likely another sniper was still active when he exposed his head and pumped his fist. I love him for it and believe God is on his side, but he got extremely lucky.

The only difference between him and JFK was that they missed. There could easily be an alternate universe where they missed JFK in Dallas. I Imagine, in that world, people accused JFK of staging the event because he was ten points behind in the polls to Goldwater at the time (which he was).
