There's no CCTVs in most residential areas here, FYI. The only places I've seen CCTVs on the street in Singapore are the crowded shopping areas.
If you come to Singapore you'll realize a lot of the draconian stuff here is basically just show-business, which is pretty sad, actually.
I laughed when I saw the CCTV thing - because AFAIK the police here are so lazy they wouldn't actually go out and nab people even if we actually had a CCTV for every house. They basically have an iron rice bowl, given that the majority seems to find policing as a job below them and, as Gibson put, everyone here already has a policeman in their heads.
