I totally agree that reducing weapons around should reduce weapon related violence, and also weapon related anything. But why does a gun in the US kill more than that same gun in almost any developed county by an N factor? Is this also a cultural factor? Or maybe social or political? Or maybe there is a threshold over which weapon violence rises with a higher exponential in relation to weapon ownership? For example over a certain threshold you end up having a significant number of armed individuals that are poor, desperate and armed which boosts potentially lethal criminality. Or stupid and violent armed people. Or maybe: over a certain threshold you have too many people that are simply both armed and stupid. Occam's razor point towards this one IMHO.
