According to Detective Chief Inspector Mick Neville, quoted today in this article from the Guardian, CCTV ain't working.
The problem appears to be two-fold:
1) the authorities don't have any plan for how to use footage generated from cameras
2) camera's are useless as a deterrent because 'people' don't 'fear' them
The answer appears to be to throw even more technology at the problem. Initiatives include using tracking technology developed for advertising, setting up a national CCTV database, and putting mugshots online.
The strategy behind these initiatives does not appear to have been revealed. Or maybe I missed it.
I'm scared already.
