Continuing the increase in high-profile mass school shootings seen in the late 1990s and 2000s, additional school shootings shocked the country in the 2010s, the deadliest of which were the Oikos University shooting, the Sandy Hook Elementary School shooting (both in 2012), the Isla Vista killings, the Umpqua Community College shooting (2015), and the Stoneman Douglas High School shooting and Santa Fe High School shooting (both in 2018). These shootings, particularly the Sandy Hook and Stoneman Douglas shootings, heightened the debate over gun politics, and continued the public dialogue about improving mental health care and school safety.
