I havent followed it closely.
Since oswald was a known cia trained asset and also worked for FBI...what is the reason he went off the reservation
He didn't.
I really want to understand how the biggest assassination in American history came off and if the CIA put Oswald up to it, who else was involved? Something of this magnitude takes more than training and putting up a 24 year-old crazy kid who clearly was a communist and hated his own country.
If you are Dulles or a high-up in the CIA and you are planning to kill the president, that is an enormous undertaking. So far the only thing we know for sure is that the crazy 24 year old did it and if there are other pieces to the puzzle nobody has clearly put them together in over a half-century.
