Columbine High School
In 1999, two students killed 13 people and injured 20 others at Columbine High School. At that time, it was the deadliest school shooting in history.
At the time, the Columbine High School shooting was the worst high school shooting ever, adding more fuel to the rising political debate regarding gun control. Two students began their rampage outside the school: After only 16 minutes, the pair had killed 12 students and one teacher, in addition to injuring 20 others. Their original plan was to set off two propane bombs in the school, but they began their shooting spree when the bombs did not detonate. The tragedy had a lasting impact on the gun control debate, as it was the first major mass shooting to happen at a high school. Additionally, people across the nation watched the shooting unfold on national news networks, watching the police search the campus and urgently evacuating students. The shooting felt personal even to those who did not have a direct connection to Columbine.
