If the Dealey Plaza shooters had missed JFK on Nov 22, 1963

The fact that at least two of the three shooters didn't miss their intended target, is proof that professional snipers were hired.

Did they ever find Oswald's "curtain rods".

We wouldn't still be talking about him because he would have just been an average president

LBJ probably had a backup plan.

I don't know. Things would have become very difficult for him.

By whom

US combat troops would have been never been sent on a large scale and withdrawn from Vietnam by 1965.

Grassy knoll?

You need to watch the fairly recent documentary you missed called JFK: smoking gun.

Basically they prove through actual ballistics science that the fatal shot was fired by a secret service man in the back seat of the car 10 feet behind Kennedy holding an assault riffle at the time. The same type of round from the exact trajectory that blow out Kennedys head.

Once this truth is revealed and you look at all the snip edited films there that day just not showing the backseat of the car behind Kennedy, it becomes painfully obvious that they actually had a secret service man, who were mostly fill ins that day, kill our President during a parade.

In one film you can even see the gun smoke as the frame begins with the cars speeding up just after the kill shot.

They had 2 guys standing along either side of the shooter car helping to block the view of the shooter.

The Zapruder film looks like an obvious plant. "Amateur" photographer who just happened to perfectly film the car passing, moving along with it and never capturing what was happening in the car 10 feet back.

Ever try to film a moving object without rehearsal? Try it and see.

All very, very interesting.

Grassy knoll you say? Lol

Pure truth. Mmmmmmmm.
