Your explanation might have been accurate if we were back in 1960. However, we are in 2014 and communication is instant.
The reason for the long delay is for no other reason than the fact that “everyone has to get their stories right” so that no individual goes against the group.
It’s all CYA and a hell of a lot of money is wasted by the use of many, many “investigators” and others who receive money to “investigate” a simple vial of blood. It’s nothing more than a “racket” consisting of law enforcement, lawyers, medical personnel and many, many others who exist solely upon the perceived need for their services.
This is the modern era and communication is INSTANT...except by any (and all) involved with the government in any manner.
You have NO idea what you are talking about. None.
