@caycepollard they did to an extent but also people realised that too much CCTV remarkably reduces the effectiveness of it. It became over concentrated in certain areas and also the cost of maintaining it went up as a result of increased data-gathering legislation - hence why about half of all working cameras aren’t even recorded.
@caycepollard London being saturated with cameras is a bit of an overstatement in my opinion - lots of cameras in some places and absolutely none in others. Approximately 1 in every 3 cameras in London is a decoy, and only 1 in 2 is actually recorded. A lot of the figures for CCTV cameras also include things like red light cameras and traffic congestion cameras, which in my opinion shouldn’t be included in the statistics.
