More than likely there would have been a cut-out who could not easily be tracked back to any agency. Mobsters or right-wing radicals would be likely possibilities to execute the shooting. They also could be in a position to take the blame as a fall-back story. Dr. Pepper's information is presented very convincingly and he may have the closest thing to a solution to the case that has surfaced since 1968. It is imperative that Ray be given a trial so that this type of information can be made available to a larger general public.
Pepper does have many interesting witnesses that can be presented.
One important issue is relating to this mysterious character Raul that Ray claims moved him around and set him up to take the blame. Attorney Pepper has found a person that he has identified as Raul. Dexter King stated that the King family supports Dr. Pepper's efforts and they feel that Ray is a patsy.
