Say it's not so, Britain! CCTV is not a deterrent?
Just imagine - the drunken rabble does not care that it's being recorded while stomping the head of a hapless victim against a curb. And they'll get away with it - another study showed that 80% of images captured were of such poor quality that they neither helped get a conviction after the fact or even identify one of the perpetrators.
Great. At least the family gets to see their loved one's last moments alive, or more commonly, being able-bodied on grainy CCTV recordings.
Maybe it would have stopped the 9/11 terrorists. Wait! They were on CCTV too!
