Thirteen years ago, the small community of Littleton, Colo., was rocked by a massacre at Columbine High School. Gunmen Eric Harris, 18, and Dylan Klebold, 17, walked into their school on April 20, 1999, and opened fire, killing 12 of their classmates and a teacher, and injuring 21 more, before turning their firearms on themselves. At the time, it was dubbed the most deadly school shooting in American history, and it changed the way many communities across the country thought about school safety. But then the nation was once again rocked to its core when a gunmen went on a terrorizing rampage at Virginia Tech, almost a decade later. On April 16, 2007, Virginia Tech senior Seung-Hui Cho unleashed a rampage on the college campus, shooting and killing 32 students, and wounding 17 more people. More than a year before the massacre, in December 2005, a district court in Montgomery County, Va., deemed Cho " mentally ill " and "an imminent danger to self and others."
