It was twenty years ago this week that America, its schools in particular, were changed forever by the actions of two high school students named Eric Harris and Dylan Klebold, who carried out a mass shooting at Columbine High School in Littleton, Colorado in April 1999. It was reported later that week that the disgruntled, heavily armed boys had set out to commit the violence on Adolph Hitler’s birthday. As a Gen-Xer, who was in my mid-twenties in 1999, I regard the Columbine shootings as a demarcation point for my generation. The youngest of us were born in 1980 and would have graduated from high school in 1998, the school year before this event occurred. Though school shootings did occur before this, during our time too, none was like this, and no school administrator in America could ignore the new reality that a shooting could happen anywhere on any day.
