Kenneth Trump (no relation to the president), president of National School Safety and Security Services, said that armed teachers "could present confusion during a live shooter event", adding: "You [law enforcement] arrive at the scene and you have seven people [armed teachers] coming out with firearms in their hands".
And he said the revelation of the deputy's inaction was further vindication for his proposal to arm teachers who - unlike law enforcement - know their schools and "love their students". The NRA is against any change to age limits for buying weapons.
He said: "The notion that my kids are going to school with teachers that are armed with a weapon is not something that".
"I'm not here to tell all teachers that they have to carry a gun", said Hansen, the Utah teacher, who's from Salt Lake City.
He also said that this could also be a preventative to any would-be attacker.
President Donald Trump, 71, met with several survivors of the Marjory Stoneman Douglas High School shooting on Feb, 21 to discuss what can be done to stop tragedies like this from ever occurring again.More news: EOG Resources Inc (EOG) Position Lifted by ARP Americas LP
Trump addresses the 45th annual Conservative Political Action Conference (CPAC) at the Gaylord National Resort & Convention Center in National Harbor, Maryland, USA, 23 February 2018.
"You had one guard. We want to be very powerful on background checks", he said.
Trump tells an annual gathering of conservative activists that few people are afforded the honor and "it's a big thing".
Trump met with local residents, including a mayor and education officials at the White House on Thursday.
"He certainly did a poor job. There's no question about that".
"That's a case where somebody was outside, they're trained, they didn't react properly under pressure, or they're a coward".More news: Azpilicueta calls on Chelsea to be "perfect" at Barcelona
Speaking at a news conference in the state capital Tallahassee, Republican Governor Rick Scott unveiled a $450 million security plan in response to the Valentine's Day rampage. There are three times as many teachers as police officers in the U.S. The expense of training and equipping them would be enormous.
Now under federal law, anyone 18 or over can buy a gun from a private, unlicensed seller, although a handful of states have set the minimum age at 21. "Yes, Trump never said to give guns to teachers willy-nilly - I mean, can you imagine what this country would be like if anyone could get a gun?" he deadpanned.
It also makes assumptions: It assumes that the teachers will not use guns they already own, and it assumes that 20 percent of teachers would carry - not likely.
But as Trump hosted a listening session at the White House with survivors and family members of victims of school shootings, he floated the possibility of arming more teachers in schools.
"Since I started this two days ago, a lot of people that were totally opposed to it are now agreeing", he said.More news: Chelsea boss Antonio Conte regrets Manchester United transfer
