"Deadly Lessons is the outcome of the National Academies' unique effort to learn important information from six different case studies of student-perpetrated school shootings. These are powerful stories of troubled youths, their families, and their teachers - presenting the complexity of the young shooters' social and personal circumstances in rich detail and describing the extensive effects of their actions on the communities involved.".

"The cases point to possible causes of violence and suggest where and how we might intervene to be most effective. Readers will come away with a better understanding of the potential threat, how preventing the violence might be approached, and how healing might be promoted within the community." "For each case study, Deadly Lessons describes events leading up to the violence, provides quotes from personal interviews about the incident, and explores the impact on the community."--BOOK JACKET.
