Some guy in England got out of his car and went to town on one of these cameras with a baseball bat (cricket bat if you please

).
Small towns and rural subs are more likely to use these cameras. Its much cheaper for them, its not very labour intensive and you can collect a ridiculous amount of revenue from them.
By the way there was special on one of the networks here about this, the camera system was fitted to a crown victoria. They basically pull up in the morning, set the car up, then leave it there till evening. Its a huge cash cow and in today's budgets strapped districts this could be coming to a two lane road near you.
