Wikipedia has a list of shootings which have occurred in our schools dating back to the 1840s. Sadly, most of the shootings in the past several decades since the mass shooting at Columbine High School have taken place in public schools. That led me to ask why private schools seem to have been spared these senseless killings.
Before we look at some of the reasons why shootings occur, let's find out what percentage of shootings occur in private vs. public schools. In Are Shootings More Likely to Occur in Public Schools? Corey A. Deangelis notes the following research:
"Hyewon Kim—a Cato Center for Educational Freedom Intern—compiled information on school shootings in the United States from 2000 to 2018 using the Tribune-Review database. The database is limited to legitimate school shootings; that is, shootings that occurred on or near a K-12 school campus while classes were in session or when students were present. The list also excluded suicide-only incidents."
"Hyewon found 134 school shootings from 2000 to 2018. Only eight of these occurred in private schools while 122 occurred in public schools. The type of school could not be definitively classified for 4 of the shootings. As shown in the figure below, about 94 percent of the shootings that could be classified occurred in public schools while only about 6 percent occurred in private schools."
