A new study conducted by Northeastern University shows that school shootings are actually not an epidemic, and school shootings have dropped since the 1990's.

The deadly school shooting this month in Parkland, Florida, has ignited national outrage and calls for action on gun reform. But while certain policies may help decrease gun violence in general, it’s unlikely that any of them will prevent mass school shootings, according to James Alan Fox, the Lipman Family Professor of Criminology, Law, and Public Policy at Northeastern.
Since 1996, there have been 16 multiple victim shootings in schools, or incidents involving 4 or more victims and at least 2 deaths by firearms, excluding the assailant.
Of these, 8 are mass shootings, or incidents involving 4 or more deaths, excluding the assailant.James Alan Fox, the professor that conducted the study says, "These are extremely rare events, and no matter what you can come up with to prevent it, the shooter will have a workaround."
