It wasn’t a drill. It wasn’t a movie. The horror was real. In a nightmare which has grown all too familiar on American school campuses, 17 students and teachers were massacred on February 14, allegedly by former school student Nikolas Cruz, who has been charged with firing an AR-15 rifle (legally acquired, according to his lawyer) into four classrooms. Since Columbine in 1999 (13 innocents murdered), through Virginia Tech in 2007 (32 dead) to Sandy Hook in 2012 (26 students and teachers killed), school shootings have developed their own numb grammar. Generally, this amounts to expressions of sympathy, a call for action, thoughts and prayers, and then nothing, until the next mass shooting, when the process is rinsed and repeated.
