Indeed this article is perfectly clear that Anne Guedes' claim about CCTV in public places is utterly incorrect.
I was wrong saying France managed to resist to the security utopia syndrome. 13 years after the UK the contagion reached France, under presidency of Nicolas Sarkozy.
At least there are (yet) no cameras in streets without other purpose than to be there just in case. A strong and justified motive is needed.
Gilet, as irresistibly rude as usual, is carefully omitting the rights of the public. The cameras must be very visible and their presence has to be clearly signalized. They therefore have at best a dissuading effect, they don't suppress delinquency, they shift it towards areas without control.

It is the second meta-analysis (the first was in 2002) financed by the HO but realized by an independent entity. It's really worthwhile reading.
