Some laws are enforced, but some are not
We live in a city and county that have laws. Some are enforced and some are ignored. If you don’t want to serve on jury duty, you don’t have to.
I live in a one-family area of town, with college students living everywhere. They don’t take care of the yards, so the neighborhood is in terrible shape. We have laws against loud vehicle noises, but they are ignored.
We have laws to prevent fireworks in the city, but they can’t be enforced. We have laws about weed control. Some are enforced, some are ignored.
