YouTube videos aren't very his source material, so I found this instead:
http://www.shroud.com/pdfs/Fanti-refl.pdf
I see so you took selective parts of his answers without showing the questions, rather than showing what was actually said and you have assumed that this is a genuine document. That's hardly scientific now is it. So lets ASSUME this is a genuine statement he gave, this is what was said by Dr Fanti in full:
Q3. Do you believe the Shroud is likely the burial cloth of Jesus Christ, a fake
relic, or are you uncertain what to believe?
I must separate scientific aspects from religious ones.
From a scientific point of view both my researches and the studies performed by
the students (of Mechanical Engineering) in thesis with me ALL lead to a
confirmation of the authenticity of the Shroud even if, up to now, no sure proof
has been evidenced.
From a religious point of view, I am sure that the Holy Shroud is authentic and it
is the most important Relic of Christianity. This because, following a precise
question of mine, I had a personal “answer” in 1998 in front of the Relic.
Q9. Do you favor or believe any of the current theories on how the image got
onto the cloth? If so please name the theory.
It’s a hypothesis, not a theory because it is not yet validated by science. In fact,
at this moment, the body image cannot be completely explained nor reproduced
by science.
I am, however, convinced that the Coronal Discharge played an important role in
the body image formation.
So he does believe it is the genuine burial shroud of Christ which he confirms in the documentary and that a plasma coronal discharge was involved in forming the image on the shroud which he also confirms in the documentary. It seems you commented on the documentary without even watching it first, not very scientific of you at all. You should retract your groundless assertion and in future do the research before voicing twisted half truths.
