School shootings are a social phenomenon

I reviewed this book in June but I just wanted to mention that The Tipping Point might be interesting to read after the shooting that happened in Finland. Gladwell proposes an interesting theory on social phenomenons touching the youth which could very well explain the current outburst of school shootings. This new epidemic could be far from having been reached its climax if nothing is done to counter it, and by this I don't mean simply toughening gun laws.
