My town has over 30K people.

You don't have to lock the car, in fact you can leave the car unlocked, with a nice laptop in the rear seat.

You don't have to lock the door. I've even forgotten to lock the front door a few time and left for a week. Came back and I walked right in the front door. Nothing missing.

Of course there were those terrorists that got arrested by the FBI 4 blocks down from my house.
