That particular retort is attributed to Albert Einstein. But, he was referring to something theoretical: his Theory of Relativity. But, this does not concern a principle of the universe; it concerns something much more mundane; the identity of a person in a photograph. And for something like this, the more evidence one can provide the better.
The role of the Oswald Innocence Campaign is to act like Oswald's lawyer. That's what we are. And obviously, a lawyer in defending his client would present as much evidence, multiple and overlapping, that he can. We are building a case here for innocence; Oswald's innocence. The more exonerating evidence the lawyer can present to the jury the better.
So, you can't compare the forum of Math and Science to a courtroom. In a courtroom, you can never have too much proof.
