Then I realized that in dealing with theorists no evidence will suffice. Like the JFK assassination, the 9/11 disaster, Man Made Global Warming, Area 51, Over-population, Crop Circles, Uri Geller, etc. People are going to believe how they want.
Hands raised if you drank from any conspiracy kool-aid in the past. Mine is right there with you.
Case in point: Barry's Birth announcement was in two separate papers when he was born. These are released by the hospital to the newspapers.
However, the reaction to the above information is that the papers were faked. Or they smuggled the baby into Hawaii and pretended he was born and released that announcement to two papers. Because they knew in advance that this child was to become a President...
So you could produce the doctor, nurses, film, birth announcements, quantify them beyond a reasonable doubt and your theorists would still "Demand further evidence"
