GUN CONTROL
PENCER PLATT/GETTY
THE GUN VIOLENCE ARCHIVE DEFINES A SCHOOL shooting as “an incident that occurs on property of the elementary, secondary or college campus where there is a death or injury from gunfire.” The archive, a nonprofit that began tracking school shootings in 2014, after a gunman killed 20 first-graders and six adults at Sandy Hook Elementary School in 2012, has recorded 239 subsequent school shootings nationwide, with 438 people shot and 138 killed.
