The horror that unfolded at Stoneman Douglas High School marked the 18th school shooting in 2018 and 25th fatal school shooting since 1999. Smith, a longtime gun control advocate, made a point of noting the nation's long history of shootings that have plagued school hallways and classrooms.
"Since Columbine in 1999, there have been 25 fatal, active school shootings at elementary and high schools in America," Smith said. He then went on to list every fatal school shooting in chronological order, placing specific emphasis on the 2012 Sandy Hook Elementary School tragedy in which 20 children and six adults were killed.
