If/when you read his books you'll see that he spends most of his time exposing the fraudulency of the major conspiracy claims, chiefly the ones promoted by the "Garrisonites" such as Stone and DiEugenio et al, and very little time promoting the lone assassin view. This is more true with his second book about Garrison's incredible abuses in his investigation. In his first book, he explains how he became a conspiracy believer - he mentions seeing the Zapruder film on the Geraldo Rivera show - and how after checking original sources like the WC he came to realize that he was misled if not outright lied to.
So he's more of a anti-CT author than a pro-LN author. ....
Steve, at least Joan Mellen is sincere, sincerely conned by Jim Garrison. Mr. Litwin, OTOH, has had the benefit of newer available information but has chosen instead to "stick to the script."
Joan Mellen first met Jim Garrison just months after the Clay Shaw trial in 1969 and described interviewing more than 1200 people before publishing her book on Jim Garrison, “Farewell to Justice.”
More than 30 years after she first met Jim Garrison and in addition to much other research and interviewing 1200 people, this was the crux and the emphasis of Joan Mellen’s presentation on the best supported CIA influences/interference on Garrison’s investigation and his prosecution of Clay Shaw.
