Yesterday’s shooting at a community college in Oregon is the seventeenth shooting on a college campus this year. That’s according to the national advocacy group Everytown for Gun Safety, who’s been tracking school shootings since 2012.

After each incident, police and security on college campuses review safety procedures and hope violence doesn’t come to them. The same is true at Ball State University in Muncie, where University Police Chief Jim Duckham says officers spent part of the summer training for an active shooter situation. Duckham says the training showed that in incidents like the one in Roseburg, Oregon, communication between first responders is key.

In 2013, before Duckham was employed at Ball State, the Muncie campus was locked down for hours after a report of a possible gunman. University officials later said that report was inaccurate and no threat was ever found. Duckman says his department is in touch with university police departments around the country, who routinely share information about events like these and learn from what other departments have faced.
