I really would like to understand why these young men seem to implode on their own group, when tensions in societies across the world usually lead one group to vent their fury, anguish or frustration upon people of a different race, culture or even economic group.
I think the pack mentalities and gang affiliations we see today, may develop when the adults in our society relinquish, avoid or refuse to take responsibilty for the behaviour of children and do not act as the stabilising and responsible force that nature intends them to be.
We may worship at the altar of youth today, but maybe this is inconsistent with our anthropological selves. Maybe adults and the wisdom of the elderly are far more important in the development of happy and fulfilled young lives than we realise or are prepared to admit in our modern, throwaway, western society.
