"Dan O’meara has answered the call, specifying just four (I think it’s more like eight) conspirators. In either case, a small conspiracy that just might work."
What do you mean when you write "I think it's more like eight"?
“Eight” is my number, after looking at your claims.
You have four conspirators. You also have three who were not conspirators but, for some reason, just happened to tell lies that helped the conspiracy. You also did not include Oswald because he believe he was told to provide a rifle but did not realize there was a conspiracy. I think it is more reasonable to conclude that all eight were involved in this conspiracy that you postulate.
However, four, or eight, it doesn’t matter that much. Either way, this qualifies as a small conspiracy theory.
