Agreed , Video Cams and Fence. And be sure to let them see you install the cameras. I had an issue with some neighbor punks that egged my cars and house and broke into my wifes car. One week later I was installing the cameras and the same kids saw me, havent been hit since. Theres no pill for stupid and these lovely neighbors you have may not take the hint. But atleast you will be able to add video to all your documentation to build your case. Good luck
