Suspicious behaviour: James Delingpole pretends he's unaware of RDH's Saffie Roussos theory

We know James Delingpole isn't stupid, so why is he playing dumb when it comes to Richard D Hall's Saffie Roussos theory - that the parents were using the 'hoax bomb' to cover up their daughter's death. It's all very suspect, especially considering I got in touch with him to point out all the anomalies and he responded but refused to have me back on his show. Why he is pretending he doesn't know about RDH's theory? And why is he pretending 'somebody' might have mentioned it at some point? That somebody is obviously me! Something is not adding up here. Major alarm bells ringing. Pay heed.
