Absolutely true that the camera's only catch you if you're breaking the law. However, it is definately a step towards big brother. The slippery slope comes to mind here. Cameras to catch you speeding, then cameras to catch you doing anything at all if it is illegal, and how many things are illegal? Some more important than others. Bottom line, although video survelience can be a very usefull tool to catch "criminals", the invasion of privacy and potential for abuse is not worth the possible and very PROBABLE abuse of such power.
