I would propose that it’s entirely pointless to focus on gun violence specifically because it’s defined not by what makes it a problem (the violence) but rather by the arbitrary tool involved (guns). You could reduce gun violence to zero, and nothing would be better if the overall violence stayed the same. Which literally all available evidence demonstrates that it would, as you’re not the first person to want authoritarian gun grabbing in place.
So then surely you should be able to provide hard data that shows reducing gun violence has a specific and measurable impact on violence as a whole, no?
