1973 threatening letter re Kennedys

I don't know where to put this and I don't think it's a Z letter per se. The FBI just released its documents regarding threats to Edward Kennedy and this is one of them. What interests me is the claim in this letter sent from Los Angeles that "He/God" lives in Vallejo and it has something to do with Mare Island and nuclear power plants (there's a nuclear angle to Z, but I don't want to go into it here). I think it may have something to do with the case.

Here is the FBI document. Go to pages 42-44. See, esp., p. 44. Copy this link (start from the end and work backwards) and put it in your browser and you'll be on p. 44 (read the handwriting section in the middle of the page)

These two items reminded me slightly of some Zodiac writing, and the ornate writing on the possible Hautz envelope and the card to the Lass sister.
