None of those things are a link to the assassination.
Since the evidence that Oswald did it is overwhelming, any theory that LBJ or anyone else was involved would have to produce some evidence of them getting Oswald to do it. There is none for LBJ.
"I could go on, but suffice it to say there are a number of well researched books on this subject out there."
There are a number of "well researched" books showing just about everybody did it.

The case against Oswald is reasonable IF you take the Warren Commission conclusions.
However, when you look at how the Warren Commission was spoon fed material and not given other material then you can begin to see how the FBI, CIA NSA, ONI, SS and many others destroyed vital evidence.
So, yes, the Warren Report worked with the information they had and in retrospect, they were given “scrubbed” material.
