The '''Columbine High School massacre''' was a [[school shooting]] and [[attempt]]ed [[improvised explosive device|bombing]] at Columbine High School in [[Littleton, Colorado]], near [[Denver, Colorado|Denver]], that happened on April 20, 1999. Eighteen-year-old [[Eric Harris]] and 17-year-old [[Dylan Klebold]] carried out the massacre and were both students at the school. They [[mass murder|murdered]] 12 students and one teacher using [[firearm|guns]]. Ten of the murders happened in the school's [[library]], where they then [[suicide|killed themselves]] with their guns. Before the shootings, they had planted two large [[propane]] [[improvised explosive device|bombs]] in the school's cafeteria. They could have killed many people in there, but did not explode. They also planted two [[car bomb]]s in the school's parking lot, which were supposed to kill [[first responder]]s and [[news reporter]]s. They also didn't explode. They also carried [[pipe bomb]]s and [[molotov cocktail]]s, which they lit and threw. Most of them exploded but nobody was injured or killed by any of the bombs used during the massacre.

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 [[bullying|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.<ref>{{Cite web |url=https://www.usatoday.com/news/nation/2009-04-13-columbine-myths_N.htm |title=10 years later, the real story behind Columbine - USATODAY.com |access-date=2017-08-30 |archive-date=2012-04-22 |archive-url=https://www.webcitation.org/677IioI03?url=http://www.usatoday.com/news/nation/2009-04-13-columbine-myths_N.htm |url-status=bot: unknown }}</ref> Other people blamed parts of the [[media]], saying that the lyrics of bands and singers like [[Marilyn Manson (musician)|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 (musician)|Marilyn Manson]].<ref>[http://pov.imv.au.dk/Issue_16/section_1/artc3A.html Bowling for Columbine: "I Want Them to Leave Angry"]</ref>
