Of course, I called the police and they took a report, but I doubt anything will be able to be done about it. I did find a small jack knife on the front seat of my car which I turned over to them. Perhaps there will be fingerprints. They told me I am not alone. I spoke with neighbors and learned that some others have had their cars tampered with, and personal items stolen.
Obviously we need to keep our car doors locked. Some of the neighbors I spoke with admitted they hadn't done so. I am going to install very bright motion sensor lights in front of my garage and over my front door.
