The matter of what will be accepted by steampunk as "scientific evidence" would seem to be a major issue of contention if the current debate gets past the Proposal stage.
It could, of course, be argued that the standard of evidence should form a part of any Debate itself - i.e. since it is likely to be a point of disagreement that may prevent participants from agreeing to debate at all, it should simply be absorbed into the Debate as an issue to be debated. But this is a question for potential participants to settle in this thread.
You are right to emphasize this. steampunk's theory that there is any debate at all turns on a premise that best evidence can be selectively dismissed. In particular he wants the opponent to set aside the legal record, claiming:
Your link is not scientific, it is judicial. There is a difference. This is not LawForums, it is SciForums.
Wrong. Forensics includes studying best evidence from legal transcripts.
This, steampunk, is your achilles heel. You are pretending that the rules of evidence for a scientist are something less exhaustive than the rules used in court. The opposite is true. Science never ignores best evidence, whereas legal procedure allows that evidence sometimes be overruled under particular constraints of expediency - for example, the expiration of a deadline for filing can bar evidence from court. Obviously that has no bearing here.
Compare what you say above to your claim at post 21
The rule is based on one used in many court rooms. If a statement does not have supporting evidence, it may be removed from the record and is no longer admissible.
You can't have it both ways. You can't, on the one hand, claim that rules of court be applied, and then, on the other, complain that this is not a legal forum therefore the records of legal proceedings are barred.
Further, in post 21 you said
Any statement may be challenged on the grounds that it is not empirically supported.
Proceedings of a legal tribunal are empirical. They are just as authentic as the proceedings of any scientific society, and the empirical evidence they contain speaks for itself. That evidence doesn't need you at all.
Furthermore, in post 21 you say
The party making the statement gets three chances for each challenge to come up with supporting evidence.
This was probably an attempt to suggest that your definition of "empirical evidence" is as broad as the legal definition of "best evidence". But you got called to the carpet on that. Xotica pointed out that, among best evidence available for discovering the facts at issue are transcripts of legal proceedings. Fearing the evidence you just got though advocating above, you said (of this evidence):
There is no science, only text and authority. I'm only interested in scientific proofs, not legal authority.
This is backpedaling from your pretense of defining evidence as courts do.
It's a fundamental fallacy to claim that science operates under anything other than best evidence. And since, in the case of crimes more than 60 years old, the best evidence available today includes the evidence authenticated in court, under rules designed to reject any evidence which might be tainted, no honest scientist would ever contemplate throwing any of it out.
Therein lies the rub. You can't pretend to appeal to science by rejecting best evidence. And the evidence you expect to admit into debate has not even been subjected to verification and authentication already done by the courts. So why should anyone cater to you, just to give you a handicap, so you can trot out an argument for Holocaust denial that simply ignores best evidence?
There's no credibility, no merit whatsoever to this pretense of proof. It's frivolous, manipulative and dishonest. Until you can man up to the hard cold facts as we best know them to be true, you're just playing on shock appeal and a false sense of authority.
The standard of proof, is best evidence, period, no matter what pretense you are operating under.
