I also wonder if the child is just plain defying house rules and is out roaming the streets. Impose consequences if your child is found vandalizing property, especially if the incident goes unreported to the police. This may include your own property or someone else's. Try to get your child to look at vandalism from the victim's point of view. In addition to teaching your child vandalism is wrong, it's also important that you take steps to protect your own property from being struck by vandals.
Vandals are more likely to strike in dark places.
If you don't already have one, establish a Neighborhood Watch program. Statistics prove vandalism is less likely to occur in areas with these types of programs. Be aware of who is coming and going in your neighborhood. If you notice vandalism in your neighborhood, schools or workplace, make sure to report the incident to the police. Chances are if the vandals go away unnoticed and unreported they will return.
