In an interesting post over at Liberal Conspiracy, Robert Sharp argues that if liberals are going to win the argument, they need to make the point that living in a free society necessarily involves risk:
Unfortunately, although the warnings raised by the authoritarians are usually phantoms, sometimes they are based on a kind of truth. A stop-and-search policy that alienates black and Asian youths might also reduce crime; a comprehensive DNA database might actually speed up the detection of a murder. Keep the entire Muslim population under 24 hour surveillance, and sooner or later you will stumble across a disgruntled Islamist militant, ready for marytrdom.
So when I say that the civil liberties lobby must “own” these possiblities, I mean that we should admit that a more liberal approach in some areas might mean that yes, there will be another Mohammed Siddique Khan, another 7/7; that, yes, there will be another Ian Huntley, and another hollyandjessica. Only when these horrible possibilities are admitted, can we truly begin to explain that the “mythical state of absolute security” (as Dominic Grieve put it) is unachievable as well as undesirable, and so win the argument on our own terms, not those of the authoritarians and the populists.
