Educators and safety experts have urged students to deploy such unlikely self-defense tools as hockey pucks, rocks, flip-flops, and canned food. In the year since the shooting at Marjory Stoneman Douglas High School last February, efforts to prepare the nation’s students for gunfire have intensified. Later it was revealed, to the fury of parents, teachers, and students, that in fact this was a drill, the most realistic in a series of drills that the students of Lake Brantley, like students across the country, have lately endured. A later announcement prompted a stampede in the cafeteria, as students fled the building and jumped over fences to escape.

Many sobbed hysterically, others vomited or fainted, and some sent farewell notes to parents. Fearful students took shelter in classrooms. At the same moment, teachers received a text message warning of an active shooter on campus. “This is not a drill,” a voice announced over the PA system.

on December 6, Lake Brantley High School, in Florida, initiated a “code red” lockdown.
