The Christian and academic establishments are settling into the publicity meme to dismiss the lastest assertions re the Talpiot tomb.  Here's an example from a recent Reuters article:

Professor L. Michael White, of the University of Texas, said he also doubted the claims were true.

"This is trying to sell documentaries," he said, adding a series of strict tests needed to be conducted before a bone box or inscription could be confirmed as ancient. "This is not archeologically sound, this is fanfare."

And here's evangelical professor Ben Witherington:

James Cameron the movie director who made the enormously successful film “Titanic”, on the night after the Oscars, will give an Oscar winning performance at a news conference along with Simcha Jacobovici who have now produced a Discovery Channel special on the discovery of Jesus’ tomb, ossuary, bones, and that of his mother, brothers, wife, and his child Jude as well! Who knew! The show will air on March 4^th. In addition we are now regaled with a book by Simcha and Charles Pellegrino entitled The Jesus Family Tomb: The Discovery, the Investigation, and the Evidence That Could Change History just released today by Harper-Collins timed to co-ordinate with their news conference and the Discovery Channel special.

From the Christian perspective, it seems to me, such ad hominem dismissals are highly inappropriate, if not unproductive.  "Do unto others" applies to critics of Christianity as much as fellow church members.  Documentary consultant James Tabor responds with a thoughtful, detailed commentary on specific factual points; Christians should do no less.
