CINCINNATI, Ohio – An armed school resource officer’s response to a recent school shooting in Ohio is prompting calls to allow more faculty to carry guns, and more school resource officers.

Butler County Sheriff Richard Jones told WCPO Madison High School resource officer Kent Hall was on the scene nine seconds after 14-year-old student James Austin Hancock opened fire in the cafeteria on Monday, injuring four students.

“Without the officer being there within nine seconds, we feel the shooter would have stayed and took his time,” Jones said. “There would have been more people shot.”

Students seemed to confirm that Hancock was allegedly in a hurry during the shooting and fled the cafeteria immediately after firing a few rounds at his classmates. Police said he ditched the gun and tried to escape, but the policy K-9 officers tracked him down, WLWT reports.

Jones explained that Hall played a critical role in the police response, tending to the victims almost immediately after the incident, and helping to arrest Hancock. The teen now faces multiple felonies, including attempted murder. The four students wounded in the ordeal are expected to recover.

Hall is a retired Butler County Sheriff’s deputy, and Jones pointed to the recent shooting as justification for his previous proposal to allow armed former law enforcement officers to serve as substitutes in local schools, according to WCPO.

“I’m telling school boards, ‘Shame on you for not addressing this issue,’” Jones said. “You can have all the training in the world, this is an instance where you need to have law enforcement in your schools or somebody with a gun.”

A lot of parents, school and police officials seem to agree with Jones’ perspective.

A WKRC report in November showed at least 40 Ohio school districts allow teachers with concealed carry permits to tote guns to class, and many are getting top-level tactical training to ensure they’re ready to keep students safe when it matters.

School staff are attending John Benner’s Tactical Defense Institute in Adams County, with the entire cost of training covered by the Buckeye Firearms Foundation. John Benner, a former SWAT commander, told the news site recent tragedies have awakened a lot of school officials to the benefits of arming staff.

“We’ve believed in this for a long time, but never thought we’d be able to pull it off until Sandy Hook. And then everything changed,” Benner said. “Now people realize if you don’t have somebody in the school that’s armed, willing and capable, you’re gonna lose a lot of people.”

School resource officer Jeff Corder, who was an advocate against arming teachers, told WKRC that the training he received at the Defense Institute changed his mind.

“I knew I had a gun in the building and I’m a uniformed officer in the building and I didn’t want to worry about who else had them,” he said. “I’m leaving here today to talk with the superintendent and say we need to look at this.”

“If they get through a program like this it’s a total win-win,” he said.

Benner’s training program is called FASTER, an acronym for Faculty Administrator Safety Training and Emergency Response, and he said it’s designed to address the critical moments in a school shooting before police can take action.

“This is not a job that law enforcement can successfully do,” he said. “Doesn’t have anything to do with their training, their desire or anything else; they’d love to do a good job on this stuff, (but) time is the critical factor.”
