This is nothing new, there have been several Home Office studies which already prove the ineffectiveness in CCTV.
I strongly recommend the documentary EVERY STEP YOU TAKE for a critical an in-depth approach to CCTV in Britain. I heard it will be on air in UK soon, and also released on DVD. I've seen the film at Cambridge Film Festival this year and was impressed that a foreigner (Austrian-born director Nino Leitner) was able to pull off an extremely informative documentary about such a uniquely British topic.
