Over the past 43 years there have been Many Critics of the Warren Report.
With approximately 2000 books written on the subject I will NOT list all of them.
I will however mention some of the "Pioneer Critics".
Harold Weisberg
Penn Jones
Sylvia Meagher
Josiah (Tink) Thompson
My personal favorite is Harold Weisberg.
I consider Harold to be the "Dean" of all WCR Critics.
