But instead of responding to a problem, they were learning how to prevent one.
"History has shown that everybody has to be ready," said Jim Sanford of the Medina County Sheriff's department.
In an actual emergency, officers from various departments are often working together for the first time. Today's training helps prepare everyone so that there are no communication issues and everyone is on the same page.
"We're focusing on individual officer skills like movement into a building clearing rooms, moving down hallways and searching large areas" said Jim Craigo of Graystone Defense Group.
Recent tragic events involving school children have made everyone aware of the importance of being prepared.
"It eases the minds of the parents knowing that we are welcoming law enforcement into our building. We are actually practicing in our hallways in the event something would happen here" said Bart Randolph, principal of Cloverleaf High School.
The Graystone Defense Group has different agency training programs available. They have been providing training courses for communities for 10 years.
