 Sergio Arcacha Smith had left New Orleans well before Garrison began his investigation and was willing to speak with Garrison's investigators if he was allowed to have legal representation present.Further, witnesses Gordon Novel from Ohio may have been extradited if Garrison pressed the case in Ohio and Sandra Moffett was offered by the defense but opposed by Garrison's prosecution.The testimony of witnesses who placed Clay Shaw, David Ferrie and Oswald together in Clinton, Louisiana the summer before the assassination has also been deemed not credible by some researchers, including Gerald Posner and Patricia Lambert.
