in this incident..."
An increasingly common denominator.
How do we stop such behaviour? We don't, but we can drastically reduce the incidence of anti-social behaviour quite simply - by bringing up our children to have respect for their environment, and for other people.
It really is as simple as that - give your child a decent set of moral standards and he/she will not go around vandalising the neighbourhood and/or exhibiting aggressive behaviour.
Too busy thinking about yourself to bother with your own children? Then society will continue to suffer from loutish behaviour.
