“The public was often left disappointed by CCTV’s lack if impact on drunkenness and violence, he said. “… it doesn’t deter most crime. I think they are perhaps misled in terms of the amount of crime that CCTV might prevent.””
So says Graeme Gerrard, head of CCTV at the Association of Chief Police Officers. It’s good for rational beings, for example deterring theft in a car park, but doesn’t work on the irrational, including the inebriated, who don’t care who is watching them.
