Common knowledge.

It seems to me that at some point in almost every episode of the television crime programs I've watched (and I readily admit to enjoying these) someone calls up the surveillance camera footage, and now cellphone history as well, which ultimately leads to apprehending the culprits. Strangely, however, as these culprits go about their daily lives of crime, they seem oblivious to the fact that any television watcher is fully aware of there's a CCTV camera on almost every street corner.
