Growing up in a small town in the MidWest, all of the above pretty much applied! I fondly remember not only leaving the house unlocked all the time, but very few folks even removed the keys from their car when they parked "downtown". Truly amazing by todays standards! Crime was handled by the one police officer we had, and as a rule, he just wandered around the town, drank coffee with the residents, and said "good morning" or "good afternoon" a lot! We had a town jail, and I can only recall seeing someone in it once,,,,and that was a drunk sleeping off his "party" until morning, when he was released to his wife!
