After 17 people were shot to death at a Parkland, Florida high school last month, students and gun control advocates decided to organize a nationwide school walkout . The shooting at Marjory Stoneman Douglas High School was the 11th fatal school shooting since Sandy Hook in 2012. As school districts grappled with how to respond to Thursday’s student walkouts, the schools that have experienced recent fatal shootings approached the moment in a variety of ways.
