Right - mass shootings are bad for (criminal) business, and are (at least in the United States) exclusively the domain of radical actors.

Put simply - America has a radicalization vector x mental health x access to rapid-fire guns problem. Take away the rapid-fire component (semi- or fully-automatic weapons) and that would significantly reduce the mass-shootings problem.

As far as the radicalization vector goes, the abolishing of Section 230 protections would be a good start (and I am grossly oversimplifying this).

I have no solutions for the mental health component; there are way too many factors to discuss here, related to insularity, economics, education and outcomes.
