Have you read the link to Joseph Newcomer's analysis? It doesn't seem like you have. There are several problems with claiming that typewriters existed at the time which could have done some of the typography found in the memos. First, there really was no one typewriter that could do everything. Second, the things that some existing typewriters could do that match in theory, do not actually match in practice. At least, nobody has used a typewriter from that period to duplicate the memos to a reasonable degree of accuracy, and I think we can assume that people have tried. Third, any typewriters that might have been able to do advanced typography would have been very unlikely to be found in a national guard office in Texas and used by a non-professional typist to write unimportant memos to himself(!). Fourth, it would be an amazing coincidence that right wing bloggers could just open up MS Word 2003 and start typing the memos and end up with a virtually pixel by pixel match to images of the memos without any alteration at all except a scaling of copy size. Finally, there is some additional Bayesian logic working against the authenticity of the memos. Based on the typography alone, right wing bloggers called ********. Isn't it an amazing coincidence that when CBS looked to authenticate the chain of custody of the memos, it just so happened to find out that their source not only revealed that he had burned the originals, but that his story kept changing as to how he got ahold of the memos? I mean, there are presumably scenarios where some super advanced typewriter was used to type the memos in the 1970s, which led to bloggers challenging their authenticity based on fonts and formatting and the like, but where CBS actually could trace the chain of custody and determine the source or even find the originals. But we have to exclude all of those scenarios, which may easily be more than 90% of scenarios in which an advanced typewriter really did exist in the national guard office and was used by Killian. So the probability gets cut down even more.
I didn't just pick my confidence level out of my ass. I do this kind of Bayesian analysis constantly, although not necessarily in a spreadsheet. From my point of view the probability that the memos are real is about the same level that I am just completely delusional and imagining that the event even happened at all.
Your confidence level, as you posted, is that the memos are forgeries to the extent that you are willing to undergo an agonizing death if they are not. I am not at that level, which is quite a bit more confident than I (I am willing to suffer a papercut if the memos are not not forgeries).
Is the bulk of the evidence that they are forgeries?- yes I have routinely stated so. But when you look at each piece of the narrative, there is no smoking gun that rules out
absolutely all possibility of them being authentic. Just to take your statements as I have highlighted:
1. There is no reason to think that an army office had only one typewriter and one typist. My small main office had 4, and each lab had two or more, in a small department. In fact, the different styles in the PDFs you cited are suggestive of more than one typist, which is exactly what one might expect given the different dates and not what one would expect if one forger sat down to make the forgeries look plausible, but forgot all about the ligatures and the proportional spacing.
2. What exactly is it that no typewriters at the time could match in
practice but only in
theory? I'm not certain I understand this- by practice are you referring to the likely absence of these "theoretical" typewriters from National Guard office at the time? If so, see below. If not, what exactly do you mean? And why assume that people have tried to duplicate the memos and failed, or if they did that we would have heard of these attempts?
3. Do you know as a fact that these advanced typewriters were not in the National Guard office at the time? That would be a smoking gun proving forgery, so do we know it or are you speculating? These advanced typewriters were in my small departmental office in a state university at the time, so it is certainly not impossible a concept. Are there purchase orders or documents from the time that make it impossible for that office to have such a typewriter?
And remember I am not challenging your position- I have from the beginning agreed that most of the evidence indicates forgeries. But I want to understand the exact evidence
proving this so I too can share your confidence level. We are arguing a trivial point on which we probably agree 80-90 percent. But if you believe 99.9% I want to see the additional evidence that has inspired you to this level of certainty.
