Can we please stop pretending this is a court.
Innocence and guilt don’t decide the weight of obligation for the discussion.
There is an established consensus.
Whatever we feel about the implications, Good or bad, there is a narrative that best fits the breadth of evidence, and seems most likely. It is not perfect, but it is currently the best fit.
It is the Null.
In this case the null hypothesis is that events are as they seem, and evidence is varified. We have a rifle, we have shell cases, we have bullets and bullet fragments, x rays and autopsy records, photographs and film footage, the owner of the murder weapons, his false ID, his previous attempts, his ownership of the gun, experimental evidence, and many volumes of expert and witness testimony. All of this, at face value, to a reasonable level of scrutiny, points to LHO.
The most likely explanation, that best fits the most points of evidence, suggests Oswald.
Nobody has to make a legal claim, prove, or defend, the Null.
It is the benchmark against which other theories are tested.
If you believe ANYTHING else happened, present your theory.
It will be compared to the Null.
It will either fit fewer points of evidence and have more steps of complications, be as good and likely explanation, or fit more points of evidence with fewer complications.
Depending on how plausible it is, in comparison, it will be deemed more likely, less likely, or as likely as the Null.
Outside factors, legal claims, statements of innocence or guilt can be assessed after. This being a matter of history and not a court of law, the question is not if somebody is guilty or innocent, but to what degree of certainty we can level accusations.
Keep this in mind. The accusations against Oswald are not the only ones who weight will be assessed. By stating you see nothing in the evidence to suggest Oswald’s guilt, then accusations are being made against those who gathered, analysed or presented evidence, of either incompetence or in the cases of many CTs outright corruption and collusion.
These are considerations that have to be taken seriously, and not simply because one does not want to believe in the WC’s findings.
