Little bit of a back story. Two years ago I woke up to find that someone had smeared dog poo all over my car windows, door handles, and tires. I was confused and thought maybe someone thought I owned a dog and let my dog shit on their lawn. I don't own a dog by the way. Weeks passed and I woke up again to find that someone had again smeared dog poo on every window of my car, and left behind the dog poop bags that you find at dog parks. I'm now thing that I must have cut someone off and they followed me home Weeks go by and this happens again, and again, and again. I later find out a year later that it's been happening to my neighbor as we'll. so now I know it's not personal, and just perhaps crazy person poop smearing cars around my neighborhood. There is no pattern, no motive, no one to suspect. Short of buying security cameras, which is expensive and not what I'm wanting to do, I have no idea how to catch someone when I have no idea when they might strike. Anybody have some good advice for me?
