It is very sad that such incidents are happening in schools (of all the places). And mind you it will continue to happen. Will it be a good idea to punish the parents for such juvenile crime committed by their children? And this need to be told to the children. At least then the children might think twice before taking up to weapons and crime. Because if the children are arrested and remanded to judicial homes, they only return as a criminal (barring a few who might transform).
