Has anyone read this book by a former atheist homicide detective (James Warner Wallace) who used the same methodology on the gospels as on a number of other 'cold' cases. In the course of this process, initiated in order to disprove the basis of Christianity once and for all, he became convinced of its validity. He even points out that the 'contradictions' match what you would expect to find from witnesses in any such case.
https://en.wikipedia.org/wiki/J._Warner_Wallace notes his credentials.
I suspect he might being applying different standards as regards the gospels compared with his day job. For example his 'witness statements' are potentially post-hoc by years, are of unknown provenance and claim remarkable things that I doubt have a related investigation protocol in the 'how to investigate stuff' detectives manual - and there are no 'forensics'.
Imagine the case being handled by Jack Regan of 'The Sweeney' fame: Carter says 'There are reports of a death, guv' so Regan replies 'right; secure there area - nobody touches the body - and call in SOCO a.s.a.p'. Carter pauses, thinking about how to say what he needs to tell his boss, and then says 'you're not going to believe this, guv, but we're being told the guy was dead for sure for 3 days - but then he wasn't - has been seen around and about, apparently'.
Regan throws his fag on the floor, grinds it under his shoe, glares menacingly at Carter, and then heads to the pub shaking his head as he goes. Cue the slow version of the theme tune.
