4. What? two teenagers walked into a Colorado school and massacred 13 people. The killings sparked wall-to-wall media coverage around the world - much of which has since turned out to be nonsense.

5. What cont. Columbine High School was the site of one of the deadliest massacres in modern United States history. It is the deadliest high school massacre in U.S. history.[2] This massacre took place on April 20, 1999, when Eric Harris and Dylan Klebold killed 12 students and one teacher, and wounded 23 others, before taking their own lives.[2]Eric Harris and Dylan Klebold

6. Why? The pair planned the attacks for more than a year, building 100 bombs and persuading friends to buy them guns. Just after 11 a.m. on April 20, they lugged a pair of duffel bags containing propane-tank bombs into Columbine's crowded cafeteria and another into the kitchen, then stepped outside and waited. Most Americans have reached one of two wrong conclusions about why they did it. The first conclusion is that the pair of supposed "Trench Coat Mafia outcasts" were taking revenge against the bullies who had made school miserable for them. The second conclusion is that the massacre was inexplicable: We can never understand what drove them to such horrific violence.
