You always have to wonder when a book writer or film maker decides to hold a press conference to talk about the claims in their book. This news conference is supposed to occur tomorrow, apparently. James White has posted a few blog articles on the matter in the past couple of days the posts are here and here. The second one has a few links that have some interesting information/comments. One of the links quotes:

Bar-Ilan University Prof. Amos Kloner, the Jerusalem District archeologist who officially oversaw the work at the tomb in 1980 and has published detailed findings on its contents, on Saturday night dismissed the claims. “It makes a great story for a TV film,” he told The Jerusalem Post. “But it’s impossible. It’s nonsense.”

The concept of DNA verification certainly is strange. How do you compare DNA to the DNA of Jesus? I guess the best they can do is to compare the DNA among the remains of those found and verify that they are related, and perhaps that they are Jewish. But even so, what relevance would that really have, other than to tie the tombs together?
