Jeg har skrevet om dette før, men atter engang er det bekreftet:
The use of closed-circuit television in city and town centres and public housing estates does not have a significant effect on crime, according to Home Office-funded research to be distributed to all police forces in England and Wales this summer.
The review of 44 research studies on CCTV schemes by the Campbell Collaboration found that they do have a modest impact on crime overall but are at their most effective in cutting vehicle crime in car parks, especially when used alongside improved lighting and the introduction of security guards.
Overvåkingskameraer har en liten effekt, men når man måler denne opp mot økonomiske kostnader og problemene rundt privatliv og «storebror ser deg», så er det neppe verdt det:
The Campbell Collaboration report says that CCTV is now the single most heavily-funded crime prevention measure operating outside the criminal justice system and its rapid growth has come with a huge price tag. It adds that £170m was spent on CCTV schemes in town and city centres, car parks and residential areas between 1999 and 2001 alone. «Over the last decade, CCTV accounted for more than threequarters of total spending on crime prevention by the British Home Office,» the report says.
The Lords report said that £500 million was spent in Britain on CCTV in the decade up to 2006, money which in the past would have gone on street lighting or neighbourhood crime prevention initiatives.
Welsh and Farrington say there has been concern that all this funding has been based on a handful of apparently successful schemes that were usually less than rigorously evaluated, done with varying degrees of competence and varying degrees of independence from government.
