The 11k

"The Columbine Report" which consists of eleven thousand pages of police and government documents related to the events at Columbine. There is a huge amount of information here, some important, some frivolous, and it can be difficult to determine what is what. Maybe at some point in the future I will go through and try to sort things out in a meaningful way. This website has done a great job breaking it down and I may attempt to emulate it at some point in the future if I ever have any time.
