Whats up with that?

So a few cities in Dallas have been installing these red light cameras to take pictures of violators and sending them tickets. As a matter of fact, I recieved one such ticket myself and have been super careful ever since, not only @ the red lights where they have these cameras installed but all red lights. But interestingly, they are now considering to ban these cameras. Apparently there are not enough violations to cover the cost of the installation & maintenance of these cameras. Well maybe people got the message (like I did). Isn't that the reason why they came up with the idea in the first place? Whats up with that?????
