I have no particular problem with CCTV as an invasion of privacy, if it's either in public places or places like shops. But I do doubt it's effectiveness, and especially cost-effectiveness as a crime-fighting tool. I rather suspect that all it'll do it convince people committing crimes to either do it elsewhere (i.e. relocates the crime to, perhaps, rural areas) or to take steps to hide their identity .... like a hoodie.

But, of course, it's a big-brotheresque tool that could be used to give "the man" a considerable degree of power, if you extend the coverage and technology far enough.
