Arnaldo M. Fernandez is a former lecturer (1997-2003) of Philosophy and History of Law at the University of Havana. He earned a Masters Degree in Journalism and taught Interpretative Journalism (2005-2010) at the Koubek Center, U. Miami. He has published a book (in Spanish) about the death of Cuban patriot José Marti (Miami, Cuban New Press, 2005). Regarding JFK research, he focuses on the Cuban connection in order to debunk the "Castro did it" and "Castro knew it" theses.
None of the Shenon's sources brought a single quantum of proof for turning plausible his Castro hypothesis. Their suspicions, impressions, beliefs, admissions, second-hand tales, and suggestions are linked to long-ago debunked stories. For sticking with them along the substantiation of his hypothesis, Shenon must concoct [various] 'facts', writes Arnaldo Fernandez.
Arnaldo Fernandez takes a (skeptical) look at the Herminio Diaz story.
