I raised a Freedom of Information request for information about the effectiveness of Bradford's CCTV as a means of detecting crime in the City Centre. I asked what I thought was a pretty simple question:
How many individuals have been charged with assault, robbery or other violent offences as a result of evidence from CCTV cameras within Bradford City Centre.
In order to obtain the required information would involve an in-depth search of each offence to establish whether CCTV contributed to the charge. For the 2010/2011 financial year there were 308 crime records for violent offences and robbery detected by means of a charge in the Bradford City Ward. At an estimate of 5 minutes per record it would take in the region of 26 hours to conduct this search. In addition, it has been estimated that it would take a further hour to provide the total number of crimes in Bradford City ward.
