Docudrama about the Columbine Massacre originally aired on Discovery Channel in 1999. Despite being dramatized the documentary focuses most on the events around the shooting instead of trying to dig too deep into the psychological background of the killers. The racially sensitive material was censored in many countries including in this version which does make it incomplete. One part that was strangely removed is Eric Harris comment on how he hated all races including white trash.
