I would set up the cameras and put some rabbits out in plain view of the cameras WHILE YOU'RE HOME WATCHING in order to catch the person in the act. I would want to know WHO it is and stop them from doing it to someone else. You may move away, but whoever moves into your house may become the new target. If the police don't do anything to the person because nothing was actually SEEN then I would go door to door telling each and every person in my area what happened, who the person is and to be careful. That's about all you can do if you don't have the law helping you. It's disgusting!
