You bring up some excellent points,
@allboys ...my family lived in Marshalltown for quite a few years, beginning when I was going into my junior year of high school. That summer, when we moved in, my stepmother & all of us kids went on vacation for a couple of weeks, so my dad's car was the only one in the driveway during that time. My dad was typically out every evening until 11 pm or so. When we bought the house, a guy had been renting it- he was an alcoholic and pretty sleazy (IMO); I remember meeting him when we came to look at the house, and he was in a bathrobe surrounded by 2 or 3 half-dressed women, and the carpets were covered in puke stains. My parents didn't have the locks changed after we moved in (stupid!). Anyway, my dad came home one night, and our dog- a 150+ lb. Saint Bernard, came up to him in the driveway, bleeding badly from his head and face. The dog had been in the back yard, which was fenced and not connected to the house, so the perps clearly knew the dog wouldn't be inclined to hurt them, even though he was huge. Turned out that the son of the renter had a record of burglary ( among other things); he and one or more buddies had gone through every room of the house and robbed us blind; months later, I was still discovering things missing from my closet, drawers, etc. Our dog died a week after the robbery from a blood clot in his brain. My dad heard footsteps and one of the back doors slamming when he entered the house, and there were muddy foot prints everywhere. The stolen items were mainly things that could be easily pawned/fenced, including a pair of antique Russian dueling pistols (we guessed that the dog had been beaten with one of those).
We were robbed 2 or 3 more times over the years (my parents rarely locked the doors, and although we always had huge dogs, it was common knowledge that they were friendly). My point is that it's easy to become a target for crime, even if you're not initially well-known to the people in the area, and after you become known. Just my experience, FWIW...
