Videos taken after Wednesday’s mass shooting at Apalachee High School in Winder, Georgia, show a certain calm amid the chaos.
Alexsandra Romero, a 15-year-old sophomore student, was sheltering in a classroom with her classmates when she captured footage of police officers entering the room and directing them down a corridor to exit.
“In line down the hall behind that deputy,” an officer is heard saying. “Hurry up, come on, let’s go. We have to evacuate an entire school, guys, come on now.”
Romero told the Atlanta Journal-Constitution that she thought it was a drill.

“I remember my hands were shaking,” Romero said. “I felt bad because everyone was crying and trying to find their siblings.”
Another video, which the teenager recorded on her way out of school, shows a body covered with a sheet, surrounded by blood, and firearms lying on the ground.
