Very well written and especially researched book by a reporter, Dave Cullen, who was there at Columbine and followed the case long after the rest of the media moved on to the next horror show.
Columbine demythologizes so many of the absurd and, what have sort of become urban legends about the killers: They were racists, skinheads, goths, trench coat mafiosos on a mission from Marilyn Manson, satanists, haters of jocks on the hunt for Christians .... Wrong.... They weren't any of those things, regardless of how the media and some local law enforcement officials erroneously depicted them at the time.
Even after reading the book, reading lengthy excerpts from the killers' diaries, there's still no definitive answers to the infinite arrays of WHYs?
While I recognize what a stellar job Dave Cullen did in researching and writing Columbine with its sensitive, non-linear structure that better explained the incident than writing a straight A-Z timeline, I still don't recommend it, even though it's good, if not great.
Columbine is just too damn depressing, great read or not.
