But who will watch the cameras watching the cameras that are watching the cameras?

In England and Scotland people have this small good habit of torching speed cameras. So many burn that they plan on putting cameras to watch the cameras.

Speed cameras in the Scottish Borders may soon be monitored by security cameras to protect them from vandals.
It is among the measures being considered by the Lothian and Borders Safety Camera Partnership.

There have been seven camera attacks in just three years, with machines being set alight, damaged or pulled over.

So you end up with cameras, watching the cameras. This sounds like an idea that Inspector Clouseau would support.
