Its always a neighbor who hates kids. More to the point they can't stand kids playing and having fun. I've had calls from the city on a few occasions for fixing my own car in my driveway. I know who is doing it. Its a elderly woman with a mid forties autistic son who is at her beck and call. I fear for that hateful young man when she passes. I had the hood off my car fixing something close to the firewall and he stood in front of my driveway with a really cheap fiip phone taking photos. I started to call the police but figured it wouldn't result in anything useful.
