I agree; there is absolutely selective and biased placement in many municipalities. That's another good reason to put red-light cameras on every light, and to turn traffic violations into a sliding scale based on income, car value, and other factors (like the car's weight, as a good proxy for the damage it can do to pedestrians or other drivers).
