Is There a Social Contagion Aspect of Mass Shootings?

i wonder if it could be the case that there are certain amounts of people in our a gun flooded society who are going to enact violence on others. I mean, thers perpetrators we've studied who were trying to decide between whether they wanted to be a cereal killer or a mash shooter. So'm kind of wondering if we're just kind of, you know, squeezing the sand bag on one and the sand just shows up on another side. Ye, that's actually, we write about that in our book. We discuss, sort of, as the cerial killers have kind of disappeared, in a way. In part of that, as you said, is a lot about police method.
