"Good guys with guns are the best defense against bad guys with guns," or so goes one argument. But how does that theory stand up in practice? Rita Braver takes a closer look...
[An earlier version of this story was originally broadcast on Match 13, 2016.]
The video surveillance from an Albuquerque motel shows it clearly: A man paces the corridor; a woman exits her room to get something from her car, and then returns.
"And from out of nowhere this guy came back around the corner," recalled Lynne Russell, "and this time he had a gun and he was pointing it right at my abdomen."
At that very moment, Russell's husband, Chuck De Caro, emerged from the shower. He recalled: "He then moved the gun from pointing at my wife to pointing at me, and he said, 'I need your money.'"
But the gunman did not know that Russell, a former CNN anchor, and De Caro, a former CNN reporter who trained as a Special Forces soldier, habitually travel with guns that they are licensed and trained to use.
Russell was able to slip her gun from the nightstand into her purse, which she handed to De Caro, telling him "'Take a really good look inside here; see if there's anything you can find that we want to give the man.' And Chuck looked and he said, 'Yes, there is."
And, they say, as the suspect started to shoot, De Caro fired back: "And I killed him," he said.
"But you got shot yourself?" asked Braver.
"Well, that's the nature of the game," De Caro replied. "It's called combat."
You might call them "Good Guys with Guns" -- an idea touted by Donald Trump after the June attack at an Orlando nightclub:
"If one of the people in that room happened to have [a gun] and goes Boom! Boom!, you know what? That would have been a beautiful, beautiful sight, folks! That would have been a beautiful, beautiful sight!"
It's become the rallying cry for Wayne La Pierre, CEO of the National Rifle Association, the nation's most prominent gun rights group:
"The only thing that stops a bad guy with a gun is a good guy with a gun."
We asked to speak with LaPierre, but instead the NRA provided former president and current board member Sandy Froman, of Tucson.
Braver asked, "Could a good guy with a gun really stop a terrorist attack?"
"I think a good guy with a gun could protect himself or herself," Froman replied. "I think if you have a choice of using your gun to save your life or having your life taken, then yes, I think you should have that choice."
"Basically the thought is, the more law-abiding people who own and are trained to use guns, the safer we'll all be?"
"Exactly, exactly," she said.
This is also a personal issue for Froman, who purchased her first gun at 32, after an attempted break-in at her home.
"I think that we all need to be prepared in case something really evil happens to us," Froman said.
And gun sales are up, with background checks on buyers hitting a record high of more than 23 million last year.
Even some school personnel are preparing for the worst, while many gun rights advocates say it's time to end most bans on guns in public places, known as gun-free zones.

But Dallas Police Chief David Brown, speaking after five officers were shot and killed, says these "good guys" actually complicate matters for police: "It's been the presumption that a good guy with a gun is the best way to resolve some of these things. Well, we don't know who the good guy is versus who the bad guy is if everybody starts shooting."
Colin Goddard has been in the thick of a gunman's attack. He was in French class at Virginia Tech on April 16, 2007:
"You could hear it, and then it was getting louder. All of a sudden you could see bullets coming in the front of the classroom where we were," he recalled.
Goddard was lucky. Though shot four times, he recovered. Thirty-two people were killed. Yet he rejects the idea that "good guys with guns" could have saved the day:
"That was never really a thought that came in my mind during the course of the event," he said. "I was much more concerned with how can we do a better job of stopping the one gun from coming into that classroom than trying to put a gun in every single classroom of my school, you know? That felt like it would be a much more dangerous situation."
Goddard now works advocating for stronger gun laws that, he says, would keep guns away from bad guys in the first place.
But the NRA insists we don't need more laws.
"Every time you pass a new law instead of enforcing the existing laws, you further burden law-abiding citizens," said Froman.
As for Chuck De Caro, he's undergone six surgeries. He and his wife, Lynne Russell, believe that their right to bear arms saved their lives.
But they say being a good guy with a gun is not a political decision, but a personal one:
"I don't tell anybody, 'Go out and get a gun,'" said Russell. "I don't, right? But if you're going to, you should be very well-trained. And then understand that even if you have to use that gun to defend yourself, that life is never gonna be the same again."
