Yes. But, to be fair, it has worked. London is lauded throughout the rest of the UK for its complete lack of violent crime

Indeed. When I was attacked near Clapham Junction and had a bottle smashed on my head, the police said it was too much trouble/costly to pull the video footage.

A friend had his bike stolen from outside Sainburys. They have high resolution viedo of it happening but refused to shared it with the local police without a court order.

Similarly a friend that runs a bike shop near a Tesco can't get Tesco to share high resolution video of burgalars breaking into his shop. They have it but it's their corporate policy not to share it.

On the one hand I guess right now all this surveilence is siloed to some degree and so less likely to be abused. On the other these seem like perfectly ligitimate uses of video to fight crime.
