Absence of evidence is not evidence of absence: you will need to dig a little deeper than doing a brain-dead search. CCTV is often just part of a larger project. When I first went digging I was somewhat surprised just how many different projects have some CCTV buried in there.
Example: National Traffic Control Centre is PFI. Part of this is upgrading the motorway matrix signs. The new Motorway Signal Mark 4 (MS4) colour matrix signs have in-built CCTV.
Other examples would be street lighting being replaced under PFI, with systems that assist the CCTV cameras, or even have in-built CCTV, such as the £32.7m scheme that will see about 14,000 lamp-posts across Knowsley kitted out with "talking" CCTV.
I have yet to see any PFI contract that does not increase cost year on year, as all of them have a clause linking to the RPI+some.
As to the personal abuse: that is just so sad.
