If were talking private houses u can only really do what everyone has suggested ^
- But with Council houses, do ur homework find out the house number the sh!t lives at and complain to your council, also ring the police on harassment, criminal damage, stone throwing- the parents will get a whole load of hassle and can face eviction, the kids wont come near the house again, but main thing is keep complaining daily and get your next door neighbour to as well more the better
