Lets take the current example of the famous kidnapping of the TV anchor's mother in AZ for example.

If Arizona was blanketed in CCTVs, do you think this kidnapping would have happened?

And if it still did happen, I'm 100% sure the suspects would have been caught by now (11th+ day since the disappearance now).
