Two issues.
Its unfair to say it is not public domain. There is plenty in public domain. It just isnt free.
Neither are any academic journals or access such as pubmed. Indeed I have professional subscriptions cost me a few hundred a year. The last books I bought on quantum theory were just that. Paid books!
All sorts of DVDs videos out there take just tesoriero " blood of christ" series, stones will cry out, unseen etc. And so on. It cost him a fortune to do these investigations (some with willessee the investigative journalist).
When I downloaded the Italian analysis of lanciano miracle from an italian science journal it cost me significant money. There are of course now english books on the subject.
On topics like the shroud, it is amazing that many of the papers are free in retrospect
As for the refusal of academia to get involved, indeed the ridicule ( and in some cases silencing of those who do get involved ) you tell me? If it is such a slamdunk to discount the evidence you would have thought that universities would take great pride in mocking the evidence. But they dont.
Soubaniecs career was nearly wrecked for daring to say what her investigations showed.
Tesoriero, relates several encounters when he wanted to test samples at various universities , germany, australia, USA who when told what the samples were, simply refused to get involved. An australian university more or less founded on darwinism, stated it would not test it simply on the basis that if he was right they would have to close the university, or so they said! In the end he found it hard to find any that would do testing for him.
Some of the research is done in universities on behalf of diocesan clients. So the tears of Akita, the blood of the eucharistic miracles of Naju, other cochambamba tested in australia were done in universities, but resulted in forensic reports not papers as happens for private clietns.
But having seen how shockingly badly the establishment oxford, arizona. zurich etc behaved over the shroud dating, why on earth would investigators want to sign up for more of the same? You speak of potential (but unproven) believer bias. Sceptic bias is demonstrably worse. Ask ray rogers - the antics of scientists intent on disproving the authenticity of the shroud, they lost all sense of proper scientific behaviour.
It is so much easier to get paid forensic reports from paid forensic labs.
But having been in many scientific conferences. I dont hold academia in such awe as you do. Some of the arguments are pathetic. They are paid for ideas, and papers are in the main plausibility not proof.
The fact dawkins now states that life came from soup and that it is as close to a fact as you can get, show sceptics have distorted academia.
As I pointed out, the pharma industry for example has to work to a far higher standard than university biopharm labs.
You're a believer, we get it.
But you say you're a scientist - as a scientist are you not puzzled by the lack of published papers on this? the lack of data in the public domain? How could we independently verify any of this?
