A spate of school shootings rocked the country in the late 1990s and the 2000s, the most notable being the 1999 Columbine High School massacre, that left 15 people dead, including both perpetrators Eric Harris and Dylan Klebold. The actions of Harris and Klebold would go on to influence many future mass killers. Others include the Westside Middle School massacre (1998), the Red Lake shootings (2005), the West Nickel Mines School shooting (2006), the Virginia Tech shooting (2007), and the Northern Illinois University shooting (2008). Those shootings led to increased debate over gun politics and media violence, as well as an increased focus on mental health, school safety, and anti-bullying.
