I was talking to a contact today about how the National Domestic Extremism Team came to be involved in the Climategate investigation. Apparently NDET was set up to deal with the animal extremists, but turned out to be rather to good at their assigned job. Having prosecuted and locked up all the available animal rights people, the team found it had nothing else to do.
My contact had concluded, therefore, that their involvement was simply a case of making work for idle hands.
