The local law-officer is Harris. He lives with the Mayor at his house next to the Store. Every morning Harris will leave Thomas' place and walk around Mineral Town. It doesn't matter if the weather is good or bad, you'll find Harris checking to make sure all is well in town. There's so little crime in town that Harris can take the same patrol every day and never come across a burgler or chicken-theif.
The only days you'll see Harris vary his patrol is on festival days. Sometimes he likes to watch the events that occur in Rose Plaza and he'll not patrol that day.
