I used to work with a guy who had permanent hassle off a certain gang of yobs ( not a council estate) tried the police,council even speaking to the scumbag parents but got nowhere ..anyhow after finding out who the mouth (ringleader)was and that the rest of them were just sheep bleating to his every word..he and his brother confronted the gang and when they grabbed the mouth the rest of the sheep just ran away then they showed him other uses for a golf club and after visiting the sheep a couple of nights later and asking them what number iron they liked best the trouble strangley stopped and he never had another problem after that..this was a man who tried to do it through the right channels but got nowhere and the law of the jungle was suffice ..............it worked for him but no doubt the scumbags found a mor vunerable victim
