Continuing the increase in high-profile mass school shootings seen in the late 1990s and 2000s , additional school shootings rocked the country in the 2010s , the deadliest of which were the Oikos University shooting ( 2012 ) , the Sandy Hook Elementary School shooting ( 2012 ) , the Isla Vista killings ( 2014 ) , the Umpqua Community College shooting ( 2015 ) , the Stoneman Douglas High School shooting ( 2018 ) , and the Santa Fe High School shooting ( 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
