Sometimes, you have to wonder if the security services deliberately aim to say things that are outrageous in an attempt to provoke a response from the public. Trouble is, I’m not sure it’s working.

We were getting into this sort of territory with some of our filming at the Cambridge Science Festival on Saturday, trying to see what the public thinks about the authorities prying into their guilty hidden secrets (ie. their genetic susceptibilities). My own view remains: it’s the job of the people to watch the government, not the other way around.

Yes, there’s a price to be paid for that, but it’s better than the alternatives.
