President Donald Trump said Wednesday that having more people armed at schools could prevent future mass shootings.

“I think it could very well solve your problem,” he said.

After hearing the devastating stories from parents and young people affected by gun massacres at schools, Trump pointed to the example of Stoneman Douglas football coach Aaron Feis, who was reportedly killed by the alleged gunman last week after Feis threw himself in front of students to protect them from the gunfire.

“If the coach had a firearm in his locker when he ran at this guy — that coach was very brave, saved a lot of lives I suspect — but if he had a firearm, he wouldn’t have had to run, he would have shot and that would have been the end of it,” Trump said.

“Gun-free zone, to a maniac — because they’re all cowards — a gun-free zone is ‘Let’s go in and let’s attack, because bullets aren’t coming back at us,” Trump said, wondering aloud about arming “20 percent of your teaching force.”

“You can’t have 100 security guards in Stoneman Douglas, that’s a big school,” he said. “It’s a massive school with a lot of acreage to cover, a lot of floor area, so that would be certainly a situation that is being discussed a lot by a lot of people.”

“You’d have a lot of people that’d be armed, that’d be ready, they are professionals, they may be Marines that left the Marines, left the Army, left the Air Force, and they are very adept at doing that. You’d have a lot of them and they would be spread evenly through the school.”

The President said he believed “that if these cowards knew that the school was well-guarded from the standpoint of having pretty much professionals with great training, I think they wouldn’t go into the school to start off with.”

“I think it could very well solve your problem,” he said.

“So we’ll be doing the background checks, we’ll be doing a lot of different things, but we’ll certainly be looking at ideas like that.”

Near the end of the listening session, the President said the White House would consider changes to the background check system and the age at which people can buy certain firearms, in addition to mental health measures and considering what institutions can do to intervene with troubled individuals.
