kids throwing rocks at our windows and garage door

It has been three months, and a group of kids (12-15 years old) have been targeting our house by throwing rocks daily. We have filed a report with the police, but they have not taken it seriously. Our family was threatened by these kids, and we decided to ignore them and avoid confrontation in the hope that they would stop throwing rocks at our home. How can I stop kids from throwing rocks at our house legally?😢
