Gerry, although I believe you and political extremist M.T.G. are among the worst phenomena ever to plague this forum, I have to weigh in here, early, but I hope not often because I don't want to further encourage your already hyper-activity.
Mr. Litwin is invested in a desired outcome where it comes to Garrison. He makes the same mistake as Mellen or DiEugenio and Stone.
I was inspired by this to attempt to find out what was least contradictory to the actual facts and follow the evidence wherever it leads to. The facts indicate Garrison and Shaw kept similar secrets, to the grave.

The “power structure” within New Orleans lies not with those who are currently in what is some temporary political position.
It lies with those who possess the capability to place these persons in the various political positions.
Therefore, Jim Garrison, not unlike any other political figure in New Orleans, did what he was instructed to do or else he suffered the consequences.
Now, if one could only resolve exactly who, within the deep south city of New Orleans, LA, would have reason to replace JFK.
Hint: It would be those who, for whatever reason, had the means and reasons to end Fidel Castro’s control of Cuba.
Just perhaps someone whom United Fruit entrusted to their most confidential tasks
Example, in Litwin's post on his website, earlier this week.:

...It is true that David Baldwin did work for the CIA in the early 1950s. He was stationed in India, but, according to Don Carpenter, author of Man of a Million Fragments, "he had been fired by the CIA for becoming romantically, or at least physically, involved with a woman, Lillian Baxter; during the relationship, certain classified information was divulged." (page 103)...
...Garrison's notations were made long after the Parrott memo was written.
He writes:
"Re: Attorney STEVE PLOTKIN:
See statement of DA assistant WILLIAM MARTIN re confidential source informing him that CIA's New Orleans "pay-master" for attorneys was attorney STEPHEN LEMANN (of major New Orleans firm of MONROE + LEMANN) and that LEMANN had retained PLOTKIN to represent individuals, connected with the C.I.A., under inquiry by the New Orleans D.A.'s office...
Mr. Litwin did not share with his readers the following, also from author Don Carpenter,

David Baldwin/Clay Shaw
I spent some time last week nailing down the relationship between David Baldwin, the ex-CIA man, and Clay Shaw. There are a lot of interesting coincidences in that one.


I don't know what Mr. Litwin considers is enough time to be "long after", as far as Garrison writing notes on the April 1, 1967, Parrot memo.
From Garrison's mid-June 1967 letter to the FCC Chairman.:

Mr. Litwin neglects to share with readers that the lawyer named in the Parrot Memo, Stephen Lemann, owned with his brother, Thomas, more than 20 percent of WDSU or that David Baldwin's wife's mother, Mildred Lyons Lemann had been the step-mother of Stephen and Thomas Lemann since she married their father, Monty Lemann, in 1947.

1946 Newspaper article describes David Baldwin's wife's mother's close relationship to Edgar Stern of WDSU one year before she became Mrs. Monty Lemann, a co-owner and director of WDSU :

Thomas Lemann's son, Nicholas Lemann, nephew of Stephen Lemann, "coincidentally" emerges as Garrison's most prominent critic and Oliver Stone remained clueless to these close relationships because Garrison did not disclose them to Stone or Zachary Sklar and neither did critic, Nicholas Lemann.
