1. I know the cops do the light thing simply by knowing a few cops.
2. I don't know where they are dispactched or anything. I could tell the difference between sirens though.
3. I know not all dispatches are emergencies that need lights, sounds, or running lights. If someone has broken into your business, for example, and the person is no longer there, there is no need for speed, lights, and so on. I'm in a larger city in another country now... and there are less sirens and stuff here. It is really weird. I know they respond and the crime rate is probably lower, but... priorities are different as well. I generally didn't see the same patterns with fire trucks and ambulances in the states, and honestly never had a complaint about them. Just the police.
