Excerpt

In 2018, shortly after 2:00 p.m. on Valentine’s Day, a lone gunman entered Marjory Stoneman Douglas High School in Parkland, Florida. Once inside, the perpetrator—a former student at the school—began shooting at fleeing students and staff members, killing 17 and injuring 14 others. In response, approximately 50 police officers entered the building to locate and neutralize the subject and provide first aid to the injured where possible.
