Sounds like you would never be able to make a decision as a juror or a judge, as to the guilt or innocence of the accused. No amount of evidence would be good enough for you. Suit yourself.
The Shroud is either a fake; real and the image of Christ; or real and the image of someone else. The scientific evidence shows, beyond a reasonable doubt, that it is not a fake. It is also extremely unlikely that it is the image of someone else.
If you think there is evidence it is a fake, then lay it out. I am really curious as to what that evidence is.
