In the last decade, school shootings have decimated communities and terrified parents, teachers, and children in even the most "family friendly" American towns and suburbs. These tragedies appear to be the spontaneous acts of disconnected teens, but this important book argues that the roots of violence are deeply entwined in the communities themselves. Rampage challenges the "loner theory" of school violence and shows why so many adults and students miss the warning signs that could prevent it.
