GREG GUTFELD (HOST): Well, the issue is there’s just a number of variables and some people find one variable, guns, more of a priority than another variable, which is mental illness. 

You could probably address the whole thing with a database, which I've talked about where teachers and relatives can submit a name to a civil court of somebody that they believe is mentally ill and should not be near a firearm.

If this was the dad's firearm, he should be held responsible for that, if this -- if this unstable, mentally ill person was to get that -- that way you don't punish -- and I talk about this with opioids -- you don't punish the overwhelming majority of people who are using the product wisely. Whether you're driving a car, or you're using opioids, or you're using weapons it's the same principle. Do not punish the lawful, target the unlawful or the mentally ill.
