In the wake of the third assassination attempt on President Trump in a period of less than two years, the President correctly concluded: “He was probably a pretty sick guy.” That came from his interview Sunday night on “60 Minutes.”

In looking for a cause the president pointed to the changes we’ve all been living through: “The internet, maybe more than anything else, has radicalized some people. It’s made them mentally sick,” President Trump said.

He’s right, of course. But how, more specifically, does that happen?

The tempting, all-purpose answer for busy people is simply to do what the president did: point at the internet.

But: What dots have never been connected about factors in the upbringing of the actors that tip them, the unbalanced, into the land of the "statement" would be killers or killer?

For the good of the nation, we need quality research to fill that very specific gap.
