That's the approach I took when two of my cars were vandalised. I went to the police station and reported who I believed had done it, the police officer offered to come around and talk to them but I said I'd do it instead. That way I had something in writing if it happened again. After talking to the kids nothing further happened. Whether the police officer said something without me knowing I'm not sure. They were known to police as the kids would throw wild parties maybe 3 times per week on average, all underage drinking, graffiting all the fences up and down my street and the school a couple of doors down, setting people's front yards on fire. They still live there but it's all quietened down in the last 6 months.
