This is one of the best documentaries on the events of the Columbine tragedy. The documentary creator makes a strong argument using witness testimony that there were indeed multiple shooters, possibly 6+, and not just the two shooters per the official story. One shooter was described as an adult man in his 30s! This means that 4 or more mass murderers got away with murder. Included in the documentary are other interesting tidbits that will definitely shock you. This is a must watch documentary.
