Oswald's tax records

[Drew Phipps]

Another possible explanation for these discrepancies is that Angleton was creating a false trail of Oswald employment records in his mole hunt. He would have to plant several different incorrect nuggets for the mole to uncover, and the pattern of which nuggets were wrong and which were right would lead him to the mole.

Let's say I have 2 "secret files" and 4 possible suspects. 1 secret file contains misinformation. I let 2 of the suspects gain access to 1 "FBI secret file", and the other 2 gain access to a "CIA secret file". Then, I write 2 "top secret reports," one of which contains misinformation. Then, I pair off my suspects with a different suspect, and allow all of them access to one "secret report" or the other.

My four suspects will then each have access to a unique pattern of biographical information as follows:

s1 file correct, report correct

s2 file correct, report incorrect

s3 file incorrect, report correct

s4 file incorrect, report incorrect

I wait for the information to leak, and then I know the identity of my mole. The more pairs of misinformation I have, the more suspects can be identified from my original pool of suspects.
