Here's the full quote. He's fully aware of violence cause by mental illness and domestic terrorism.

>> You will never live in a society when you have an armed citizenry and you won't have a single gun death. That is nonsense. It's drivel. But I am, I, I — I think it's worth it. I think it's worth to have a cost of, unfortunately, some gun deaths every single year so that we can have the Second Amendment to protect our other God-given rights. That is a prudent deal. It is rational. Nobody talks like this. They live in a complete alternate universe.

>> So then, how do you reduce? Very simple. People say, oh, Charlie, how do you stop school shootings? I don't know. How did we stop shootings at baseball games? Because we have armed guards outside of baseball games. That's why. How did we stop all the shootings at airports? We have armed guards outside of airports. How do we stop all the shootings at banks? We have armed guards outside of banks. How did we stop all the shootings at gun shows? Notice there's not a lot of mass shootings at gun shows, there's all these guns. Because everyone's armed. If our money and our sporting events and our airplanes have armed guards, why don't our children?
