Its actually that you hear what you want to hear.
This is what Trump actually said, which kind of echos what he said he said.

"Your concept and your idea about — it’s called concealed carry — and it only works where you have people very adept at using firearms, of which you have many, and it would be teachers and coaches. 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.
And this would only be, obviously, for people that are very adept at handling a gun. And it would be — it’s called concealed carry, where a teacher would have a concealed gun on them. They’d go for special training. And they would be there, and you would no longer have a gun-free zone. A 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.
And if you do this — and a lot of people are talking about it, and it’s certainly a point that we’ll discuss — but concealed carry for teachers and for people of talent — of that type of talent. So let’s say you had 20 percent of your teaching force, because that’s pretty much the number — and you said it — an attack has lasted, on average, about three minutes. It takes five to eight minutes for responders, for the police, to come in. So the attack is over. If you had a teacher with — who was adept at firearms, they could very well end the attack very quickly."
