Here's a letter that Dr. Cyril Wecht sent to Harold Weisberg in 1992:
So, in private, Wecht said that "I certainly do not subscribe to Garrison's conspiracy theories." Has he ever said this publicly?
Wecht feels it is "unfortunate" that "Stone evidently felt constrained to go along with all of that in the movie." Stone wasn't 'constrained,' he made a conscious choice!
Remember, the bottom line, as Wecht says, is that the film will generate interest in the JFK assassination.
So, who cares if Clay Shaw is victimized for a second time?
