I wrote awhile back about the seeming rush the UK government is in to create a Big Brother surveillance society. One aspect of this is the extensive use of CCTV cameras, with an estimated 4.2 million now in operation in the UK.
As noted in a story by the London Guardian, a presentation from Detective Chief Inspector Mick Neville, head of the Visual Images, Identifications and Detections Office (Viido) at New Scotland Yard indicates that, "Massive investment in CCTV cameras to prevent crime in the UK has failed to have a significant impact, despite billions of pounds spent on the new technology, a senior police officer piloting a new database has warned. Only 3% of street robberies in London were solved using CCTV images, despite the fact that Britain has more security cameras than any other country in Europe."
This does not mean, however, that CCTV cameras will be reduced in numbers. More likely, even more will be put up as a means to increase their effectiveness.
