My first thought on reading this was that it "supports" Islamic theology while attempting to destroy Christianity. I don't understand the DNA "excitement" other than that just the mention of DNA somehow sanctifies a conclusion. Junk science at its worst.
Actually it doesn't even support Islamic theology. According to Islam, Isa ascended into heaven, and will return to convert the world to Islam in preparation for Judgement Day. The alleged body of Jesus would discredit Islam's theological claims as much as Christianity's. And Muslims would be the ones who would do something violent about it. If there's any hilarious (and I have a dark, morbid, and blatantly immoral sense of humor) about this, is Cameron's attempts to discredit Christianity--attempts that will fail--will earn him a Fatwa from Wahhabi-esque imams.
But this is just bad archaeology (the archeologist who found the site has disowned the conclusions Cameron presents), bad science (what exactly is DNA going to prove?), and worse history. Yes, the disciples of Jesus willingly died terrible deaths for a known lie, a "manufactured myth". The Romans and Sadduccees had all the ample opporutnity to fling Jesus' dead body around, but couldn't, which is why the Sadducceees accused the disciples of sneaking the body out of the tomb--because the body wasn't there. The lack of functional common sense on the part of the so called "enlightened" is dangerous.
