It was one of the first well-known massacres at a school in the United States, and the one with the most deaths until the Virginia Tech massacre in 2007.

After the shooting, many people wanted to know why it had happened. Many people thought that Klebold and Harris had done it because they were bullied, and schools in the United States began talking about how to stop bullying. However, it is now thought that Klebold and Harris were bullies themselves. Other people blamed parts of the media, saying that the lyrics of bands and singers like Marilyn Manson and violent video games that the shooters played might have caused it.

In 2002, filmmaker Michael Moore released a documentary movie called Bowling for Columbine that was about why the shooting happened and about the role guns have in American culture. In the movie, Moore interviewed Marilyn Manson.

Memorials

 

HOPE Columbine Memorial Library

 

The Columbine memorial in Clement Park

Many impromptu memorials were created after the shooting. Memorials included victims Rachel Scott's car and John Tomlin's truck.

In 2000, youth advocate Melissa Helmbrecht organized a remembrance event in Denver. It featured two surviving students. It was called "A Call to Hope." The library (where most of the shooting happened) was removed and replaced with an atrium. In 2001, a new library, the HOPE memorial library, was built next to the west entrance.

On February 26, 2004, thousands of pieces of evidence from the shooting were shown at the Jeffco fairgrounds in Golden.
