That's just awful that stuff like this happens. Maybe these folks boobt trap for any would be destroyers. Since Bear-traps may be a bit much how 'bout a large pit with "pointy sticks!"
Must admit when we were young we'd (my little brother and sister) would go around the neighborhood at Christmas time and unscrew some of our neighbors lights and put em in their mailboxes. We thought it was grand fun plus didn't cause any damage just some simple chicanery!
