RFK Jr. and mauling history regarding the JFK assassination

I guess many of you saw the other day that RFK Jr said he thought there was a conspiracy in the assassination of his uncle, JFK. He said that the "phone records of Oswald ... were like an inventory of mafia leaders..."

The problem is that Oswald had no phone records since he had no phone.

It's a free country, you can believe whatever you want, but shouldn't you have to get the basic facts right?
