I was there last night, and the audience was laughing at the chap. On the issue of "no human intelligence", MI6 must not read; Imad Khadduri wrote "Iran's Nuclear Mirage". Given that Khadduri was a top scientist in the nuclear programme, he may just have had weight.
Others in the audience asked why MI6 ignores the facts about Mossad agents in NY on 9/11 dancing for joy and caught with traces of explosives in their vans. Dearlove was booed out of the room at the end of the evening, which was embarrassingly caught on video by We Are Change. Lots of this is NOT reported by the press.
My question to him was about press complicity with intel agencies. As with most questions, he wriggled out.
He was called a traitor to his face in the reception that followed, some stating he sold the UK to the US.

On top of the deliberate distortions and lies from the politicians this is an unsurprising, but sorry story of officialdom treating the public as though they had no intelligence - when really it was them.
