That thought can burst a bunch of peoples little bubbles Stan. The plot thickened when Ruby killed Oswald. Before that happened, there may not have been many theories floating around. The first one was the "Commies" did it. Once Ruby stepped in, the mob thing exploded. Crazy stuff came from everywhere and nowhere. That may very well be just what it was in 1865. JWB and his friends could have been in contact with or even negotiated with people in the higher levels of the Confederate government. I doubt those people in the high level wanted them to complete that mission after the war was over.
