Actually only the Gospel of Mark would have been written by the time of the death of the alleged son.
Most scholars date the other gospels in the second and third centuries. Mark is believed to be the only Gospel writer to have lived in the time of any eye witnesses.
The question I wish to see answered in the documentary is; we know for sources out side of the Bible that Jesus was crucified, do the bones in the ossuary of this Jesus show the evidence of the wounds inherent in this documented death?
If they do not then all of this is just hype.
Now we're getting into chain-of-custody problems. When the burial cave was first discovered, some 20 years ago, the bones were removed from the ossuaries. Cameron & his partner never actually dealt with the bones -- only residual fragments. I would think that the Israeli government is directly in charge of the remains.
