As a retired lawyer with nearly 40 years of practice in my rearview mirror, I do know that the law does not require anything like "ontological proof" in any context, civil or criminal. A civil case may be won with huge doubts, even in the mind of the plaintiff's attorney, about the correctness of the decision. Little old me has won cases where I thought, "Thank God the rules of evidence kept THAT out because it would've killed us."
Exactly. Truth is not the goal in a lawyer or a trial context. The goal there is to successfully manipulate an ignorant jury through rhetoric and/or procedural tricks.
Out here in the real world, the LN narrative has been examined, challenged, debated ad nauseam, and I believe it stands as "proven" by any reasonable standard of proof.
Only in the "real world" context of sleazy lawyer tricks.
As I stated previously, your approach just goes nowhere. You need either (1) an ironclad, no-question-about-it defeater for the LN narrative or (2) a more rational, coherent, plausible, evidence-based narrative. So far, there has been neither. "Frazier and Randle were correct and everything else surrounding the curtain rod story must be ignored" just goes nowhere.
Inquiries aren't required to "go somewhere". If the evidence leads to "I don't know", then that's where it leads. You don't just get to declare your narrative to be "rational, coherent, plausible, and evidence-based" (especially when it's not), and then shift the burden.
