CCTV Boom Has Failed to Slash Crime

Via Guardian UK -

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.

The warning comes from the head of the Visual Images, Identifications and Detections Office (Viido) at New Scotland Yard as the force launches a series of initiatives to try to boost conviction rates using CCTV evidence.

Use of CCTV images for court evidence has so far been very poor, according to Detective Chief Inspector Mick Neville, the officer in charge of the Metropolitan police unit. "CCTV was originally seen as a preventative measure," Neville told the Security Document World Conference in London. "Billions of pounds has been spent on kit, but no thought has gone into how the police are going to use the images and how they will be used in court. It's been an utter fiasco: only 3% of crimes were solved by CCTV. There's no fear of CCTV. Why don't people fear it? [They think] the cameras are not working."

More training was needed for officers, he said. Often they do not want to find CCTV images "because it's hard work". Sometimes the police did not bother inquiring beyond local councils to find out whether CCTV cameras monitored a particular street incident.

"CCTV operators need feedback. If you call them back, they feel valued and are more helpful. We want to develop a career path for CCTV [police] inquirers."

The Viido unit is beginning to establish a London-wide database of images of suspects that are cross-referenced by written descriptions. Interest in the technology has been enhanced by recent police work, in which officers back-tracked through video tapes to pick out terrorist suspects. In districts where the Viido scheme is working, CCTV is now helping police in 15-20% of street robberies.

"We are [beginning] to collate images from across London," Neville said. "This has got to be balanced against any Big Brother concerns, with safeguards. The images are from thefts, robberies and more serious crimes. Possibly the [database] could be national in future."

The unit is now investigating whether it can use software - developed to track advertising during televised football games - to follow distinctive brand logos on the clothing of unidentified suspects. "Sometimes you are looking for a picture, for example, of someone with a red top and a green dragon on it," he explained. "That technology could be used to track logos." By back-tracking, officers have often found earlier pictures, for example, of suspects with their hoods down, in which they can be identified.
