From today's letters column in the Guardian:
I have recently agreed to take on a pub in a residential part of Islington. Under normal circumstances this would have simply involved the existing licence holder signing over the premises' licence to me. Unfortunately they had gone insolvent and disappeared so I applied for a new licence, which requires the approval of a number of organisations, including the police. I was stunned to find the police were prepared to approve, ie not fight, our licence on condition that we installed CCTV capturing the head and shoulders of everyone coming into the pub, to be made available to them upon request. There was no way that they could have imposed this on the previous licence holder.
