Questions have been answered. Problem is you demand impossible proofs.

"Demand complete solutions. Avoid the issues by requiring opponents to solve the crime at hand completely."
"Ignore proof presented, demand impossible proofs. This is perhaps a variant of the 'play dumb' rule. Regardless of what material may be presented by an opponent in public forums, claim the material irrelevant and demand proof that is impossible for the opponent to come by (it may exist, but not be at his disposal, or it may be something which is known to be safely destroyed or withheld, such as a murder weapon.) In order to completely avoid discussing issues, it may be required that you to categorically deny and be critical of media or books as valid sources, deny that witnesses are acceptable, or even deny that statements made by government or other authorities have any meaning or relevance."
