A 9/11-type response is needed to secure America’s schools, much like airlines were 17 years ago, U.S. Sen. Steve Daines, told President Donald Trump on Wednesday.

The Montana Republican, during a bipartisan White House meeting on school safety, said schools needed to be secured with deadly force and that more prevention was needed to stop mass shootings like the one two weeks ago at Marjory Stoneman Douglas High School in Parkland, Florida.

“The only worse thing than doing nothing is doing something that doesn’t achieve the intended result,” Daines told the president. “The act of shooting kids is cowardly. Moms and dads want to know that when they drop off their kids, they are safe.

“Mr. President, a message of deterrence is important as we stop these homicidal, suicidal killers. There were meetings here right after 9/11, right after that horrible event occurred. And we made a decision as a nation, we’re going to secure our skies. We can never let that happen again. We had to restore the trust of the public to get back on airplanes. Mr. President, we need to secure our schools because parents want action now.”

Daines described the shooters as typically male, white and suicidal.

“And they’re cowards," he said. "Cowards can be stopped with deadly force.”

Daines said how schools are secured should be up to states and schools boards, but that there was a role for federal government. He advocated for an in-school response of deadly force against gun violence, but did not specify whether that meant arming teachers, as Trump earlier suggested.

Daines recounted the mid-February arrest of a Darby High School senior MacLean William Kayser, who allegedly made verbal and social media threats toward another student. The suspect cited the Parkland shooting in his threat to “shoot up the school.”
