Police "not using CCTV properly"

DCI Neville of the Met says too much spent on kit, not enough on people and processes. Some of the problem hinted at lower down...it's local authorities who run CCTV and they are putting them where residents are pressing for them, not where research suggests they might be useful. But who cares, some company has just "found out2 that there are a million fewer cameras in the UK than previously thought...I know its a mere journalist, but how do the methodologies compare between the private company and the academics who did the research in 2002? Its all on Newsnight tonight. sadly the piece is a puff for the programme and exaggerates in order to get punters to watch...Its yur summer homework on reliability of sources, students!
