Cory Doctorow thinks the London riots show it's time to rubbish the UK's omnipresent CCTV cameras:
The deterrence theory of surveillance had no nexus with the motivations of the rioters. The theory of street crime as a rational act is bankrupt. Evidence-led CCTV deployment shows us where CCTV does work, and that's in situations where crimes are planned, not pulled off in the heat of the moment. Parking garages, banks and jewelry stores, yes. And CCTVs make perfect sense as part of burglar alarms that switch on when the glass breaks (or buffer continuously, but only save the few seconds before a break-in). But the idea that we can all be made to behave if only we are watched closely enough all the time is bunkum.
