Starting Columbine

I am starting the book Columbine by Dave Cullen it is based on the shooting that took place in Columbine in High school a very famous shooting to be exact, it was around the time when shootings in schools were happening way to often, soon the shootings died down but then the incident at columbine the biggest school shooting in history so far i am no to sure. But i am very sure that it will be great to read all about it and read all about a depressing event.
