I would say your are wrong, the real truth probably never will be known.
The person who actually masterminded Kennedy’s killing was no doubt Allan Dulles for DCI of the CIA. Read up on it. I read 6 books last year on the subject, new information I had never read.
They named the DC Airport for him for a reason (actually many)!
You have to visit Dealey Plaza and the Book Depository.
The first thing that strikes you is that it was an easy shot (all 3) at such close range. The Carcano was a decent weapon and certainly capable of the deed. Oswald, was in fact the triggerman. Others involved may never be known, but it’s clear that Oswald had an axe to grind with Kennedy and it’s highly likely he acted on his own.
What motive would Allen Dulles have to do such an act?
