Days after the deadly 1999 school shooting at Columbine High School, Peter Langman ’84 found himself working with a teen who was considered a “Columbine-type risk.” Since then, the psychologist has been studying school shooters and researching ways to prevent these attacks. After 19 students and two teachers were killed by a gunman at Robb Elementary School in Uvalde, Texas, Langman tells us why school districts must make easy, accessible ways for students, teachers, and the public to report threats.
