Columbine by Dave Cullen

I spotted this book while I was looking for something else.  The Columbine school shooting has intrigued me over the years.  I wondered who these boys were, and why they did what they did.  There was some erroneous information that was reported after the shooting that persisted long after they were proved to be false.  First of all the boys were not loners who were bullied.  They were not members of the Trench Coat Mafia.  They wore trench coats because they were useful for hiding the guns and ammunition that they were carrying on the day of the shooting.  Eric Harris was a psychopath and Dylan Klebold was a follower.  Another misconception is that Cassie Barnall was killed because she believed in God.  The truth is that she was not even asked.  She was praying when she was shot, but the killer, Dylan Klebold, didn't say anything to her.  He asked a girl named Emily if she believed in God.  She said, "yes."  He asked her why, and she said that it was because her parents has raised her to believe in God.  Then he was distracted by something and left the room.  The author put a timeline at the end of the book.  It shows that the boys planned the massacre over a year in advance.  Also, the boys went to the prom.  It's amazing that both of them wanted to have dates and go to the prom.  Three days later they went to the school with guns and bombs.  It is a well researched and interesting book.
