CCTVs don't solve crime in UK; Scotland Yard's answer: more CCTVs!

You know all those Orwellian cameras that line the streets of London? Pretty much useless in crime-fighting. Scotland Yard's solution? More cameras!
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.
