That’s Not What Happened was published in August 2018. In 2018, a shooting at Marjory Stoneman Douglas High School in Parkland, Florida resulted in 17 deaths and 17 injuries. US schools are impacted by gun violence at escalating rates; Education Week tracked 202 events with at least one death or injury between 2018 and June 2024. The extent to which a school shooting is covered in the media often depends on its location and the number of people affected, so statistics such as those detailed by the Education Week tracker or The Washington Post’s tracker may be surprising.

While political debate surrounds the issue of gun reform in the US, gun violence in schools has prompted educational organizations to address security standards over the last several decades. For many schools, improving their security features involves updates to the building’s structure, such as modified entryways and additional cameras. Schools also consider the safety of their daily procedural methods, such as visitor management systems. When budgeting allows, some schools may incorporate additional school resource officers or other security personnel to maintain a presence in the building. Such safeguards are commonplace today, but just 30 years ago, few schools had security features because gun violence occurred infrequently in schools.
