Columbine
Dave Cullen
 Columbine has two main storylines, told in alternating chapters: the 'before' story of the killers' evolution toward murder, and the 'after' story of the survivors. There are shorter 'during' accounts of the attack, dispersed through the book. The 'before' story focuses primarily on the killers' high school years. According to the experts cited here, Eric Harris was a textbook psychopath, and Dylan Klebold was an angry depressive. The 'after' chapters are composed of eight major substories, focused on individuals who played a key role in the aftermath, including Principal Frank DeAngelis, alleged Christian martyr Cassie Bernall (another myth, according to the book), "the boy in the window" Patrick Ireland, FBI Supervisory Special Agent Dwayne Fuselier, the families of victim Danny Rohrbough and heroic teacher Dave Sanders, who died saving students from the gunmen. The Evangelical Christian community's feverish response is also chronicled. Columbine begins four days before the massacre, at a school assembly hosted by Principal DeAngelis just before Prom weekend. Scenes from the massacre are depicted graphically in the early chapters, and later through flashbacks. The book is formally composed of five parts: "Part One: Female Down," "Part Two: After and Before," "Part Three: The Downward Spiral," "Part Four: Take Back the School," and "Part Five: Judgment Day." The book contains fifty-three chapters, a timeline, twenty-six pages of detailed endnotes and a fifteen-page bibliography organized into topics like, "Psychopathy," "Government Reports," "Lawsuits," "Christians," "Evidence," "Hostages and Terrorists," "Survivors," "Media Accounts," "Police Ethics and Response Protocols," etc.
