Great investigative work about what happened at Columbine. The author studied the tapes and journals for years. He corrects misconceptions about what actually happened. Turns out, almost everything we "knew" about Columbine was wrong. It wasn't intended to be a mass shooting, but a bombing. The shooters weren't targets of bullying or members of the "trenchcoat mafia." They weren't targeting anyone (but rather wanted to blow up the whole school). Unsurprisingly, a lot of the content is sad and tragic. But what I found most fascinating was the role of the media in the aftermath of the story. Most of the public's ideas of what happened came from reporting that happened that day or immediately thereafter - and after the story was already out, it was hard to correct those misconceptions (or there was no appetite to do so). And because the stories were unfolding in real time, a rumor would get reported, students in the building would see the reports, and then repeat them as facts to other reporters because of what they saw on the news.
