I don't know how Bill intended for his theory to be taken, but I took it that he offered it as a possibility and not a fact. My thought is that Bill has gone through the a similar process that I have with regard to trying to make sense out of what we know about the knife DNA testing and results and he came up with this as a possible partial explanation, but I think he would acknowledge that this is an area where the evidence isn't available to prove his conjecture.[/quote[
It doesn't make sense because had they wanted "to scare him" into turning they would have picked a knife that fit the outline or just used his knives. They already had his knives so why the odd choice of the kitchen knife. BW has made this case numerous times and it appears he is "sure" that is what happened.
Who would? This is the kind of thing that seems so likely that unless there was evidence to the contrary, I think it's reasonable to assume that it happened.
His family or his attorneys could have verified it. He wasn't alone in a room when Mignini offered him a deal. He would have told of the offer by someone and they would be able to confirm. If there was good reason for them not to confirm, why did he publish it?
