Evan Long - \\\"The Columbine Cause: An Examination of the April 20, 1999 Attack on Columbine High School\\\" 88 minutes, color.
How many shots? How many shooters? Was it really a surprise?
Many witnesses to the attack reported other Columbine High School students in the trench coat group with Harris and Klebold as shooters. They even named them: Chris Morris (http://www.xmail.net/evanlong/tcc/Chris_Morris.jpg), Robert Perry (http://www.xmail.net/evanlong/tcc/Robert_Perry.jpg) and others. Several named an adult as a shooter in the science halls (http://www.xmail.net/evanlong/tcc/Chiseled_Face.jpg) while police mysteriously waited for hours to enter the school.
Based on the now-public domain government files related to the official \\\"investigation\\\" of the crime.
