() In the aftermath of a school shooting in Minneapolis that left two children dead and 17 people injured, former Minnesota Gov. Tim Pawlenty said there are steps schools can take to improve safety.

“The country, and local school districts included, have taken steps to harden schools, but they haven’t gone so far as to turn them into basically military facilities, nor should we,” Pawlenty told ” Live” on Thursday. “But I do think there are some common-sense steps, partially for schools … to have the ability to have physical safety, maybe security personnel on site, and that could help.”

Though he cautioned those efforts are not a cure-all and may not have prevented this tragedy, he said many schools have made progress while others still lag.

Pawlenty also emphasized the need for behavioral threat assessments and additional mental health screenings.

“There’s movement afoot in this country about how do we address isolated, angry, prone to violent mentally ill people, and it’s going to take some resources,” he said. “It’s going to take more aggressive screening mechanisms in schools, in hospitals, with law enforcement in the community, and we’re just not doing it. We’re not doing it, probably one-tenth of what we should be in this country.

“It’s not just about shootings,” he added. “It’s about the mental health and well-being of our country and our people more broadly.”

Minnesota gunman had ‘manifesto’ but no ‘specific’ motive

The shooter, identified by authorities as 23-year-old Robin Westman, died on the scene.

Minneapolis Police Chief Brian O’Hara told on Thursday that authorities executed search warrants at the church and three homes, but nothing found was helpful in identifying a “specific motive.”

He said state and federal authorities were working to comb through hundreds of pages of documents from Westman, finding “some very disturbing writings, and a whole lot of hate” so far.

Authorities “have not been able to identify a specific motive, a specific reason or a specific triggering event” that would’ve caused Westman to target the school, he told .

Westman, who legally changed names in 2017 from Robert to Robin, had “some sort of manifesto that was timed to come out on YouTube,” O’Hara said Wednesday.

That video has since been taken down, and investigators were examining the footage.
