I'm always suspicious when "discoveries" are taken to the media where they then say "let the debate begin." That's completely backwards and, clearly, Cameron and Jacobovici aren't doing science but show business.
With science, you share the data with as many experts as you can in hopes that they will find flaws with your work before you publish. And then you take it to the media -after its been thoroughly vetted and published.
These guys cherry-picked their "experts" and haven't shared the core and essential bits of data. The epigraphy hasn't been vetted; the provenience of the ossuaries themselves are largely absent and deficient; and so on.
Whatever anyone wants to call the "Jesus Tomb debacle," it certainly cannot be called archaeology. This is pseudoarchaeology.
