The whole panopticon concept mentioned in the article doesn't really work in practice though, does it? I mean the whole "you could be watched so don't do it" doesn't really discourage people to break the law, for example CCTV coverage doesn't really stop crime taking place in the areas, right? And speed cameras used to be hidden (as a supposed "deterrant") until a concerted effort to show that this doesn't stop rule-breakers breaking the rules of the road, right?
