Ferrie and Oswald question

[Lauren Johnson]

I have always thought that the people involved in this thing, that is most of them, were all working on a need to know basis.

They had a general idea of what was happening, in other words, they were working with Oswald on a project. But not what the end game was.

This is why Shaw made that call to Andrews. He did not know it was superfluous, that Oswald was about to be knocked off.

The people involved in the cover up, like the Paines, did not what they were doing.

Not that I know enough to make an intelligent argument. Not by a long shot. My question is around for what purpose were these people kept in the dark. My suspicion is that the people running the operation were laying some false tracks just in case there was some impertinent investigator that got off script. Run him out into a swamp and wear him down.
