As the Mississippi State University campus was locked down amid ultimately false reports of a gunman, students and staff on the Sac State campus took part in a drill to prepare for a similar situation.
Campus police say the close call across the country added a sense of urgency to Thursday morning's drill.
"It's a new philosophy, really. It's not 'if,' it's 'when,'" Lieutenant David Heaphy told FOX40. "That's the mindset you have to have. You never know when or where, so you have to be adaptable, flexible."
The drill was made to look as real as possible. Crime scene tape surrounded buildings. Different agencies were working together.
Sac State was the first college to use laser guns, like one would use in laser tag, in this type of drill.
"They feel exactly like (real guns), so you are able to deploy that. The system also registers who did the shooting," Sacramento State Police Chief Mark Iwasa said, adding it's important to be prepared for anything.
The school also tested its emergency notification system, sending push notifications to cell phones, and alerts to email and social media.
