There I am, still smarting from the bitterly ironic revelation that George Orwell’s house has 32 CCTV cameras overlooking it, and then I read this: a new type of urban surveillance is being trialed in the UK, a flying drone that watches for ‘suspicious activity’ and then trails the potential perpetrator from 550 feet in the air, recording all the while. It may be time to commit to that often-considered move to Europe.
