I think their problem is essentially rooted in their closed-community mentality. I read their discussions when the C&V report came out, and they were absolutely desperate to discredit the report. They ran around in their bumbling amateur fashion trying to pick holes in it, and came up mainly with criticisms of the reference list. Which I didn't see being raised in court at all. They also decided that C&V were academics with no practical knowledge of what they were talking about, and that the DNA was there anyway so it didn't matter.
They allowed nobody into their little group to present a contrary view about the laughable video of the evidence collection, or even to remind them that C&V were the court-appointed experts and their report was in fact absolutely damning. They decided the report was discredited, and that was that.
Then, in court, of course the prosecution made some of the same points. The PMF crew applauded and cheered and patted each other on the back for being right. That's fine, C&V have been neutralised, the report is off the table. No dissenting voice is heard or allowed to be heard, so this is taken as a definite conclusion.
The possibility that Hellman didn't agree with the prosecution's criticisms of C&V doesn't even seem to have crossed their minds. (Some of) the same criticisms they themselves had thought of were made in court, so they were self-evidently correct. Hellman must think as they do, because obviously nobody thinks any differently.
I think it may come as a big shock to them to realise that Hellman understands C&V very well, and realises that they have completely trashed the forensics. For the simple reason that if he had been minded to accept that the forensics were valid, he would more or less have been bound to have allowed further reviews of the evidence the defence requested.
