I am not saying this; all the proof is in the WC testimony.Nope. You are declaring a need for a burden of proof, and ignoring the Null.
In this case the Null is that the evidence as presented in the WC is correct, and their conclusions are accurate. You are the one making the affirmative case that their findings are inaccurate and the rifle shipped is not the murder weapon.
I have stated facts and only facts; others are claiming assumptions. Nobody, including you, have shown that Klein's shipped a 40.2" rifle to Hidell.This is why you have not convinced me you have a point. You are avoiding the responsibility for placing your contention into context, you are avoiding describing any implications of the change, and you are avoiding showing how it makes a viable difference to the narrative.
This is because you cannot provide anything counter to the facts.I see no reason to reverse the burden of proof this late in a conversation that has been going for several threads now.
