So it would be reasonable to assume there are other factors at play?
The first stop in such train of thought is the method of homicide, which guns make infinitely easier than virtually anything else.
correct however the simple existence of a weapon does not automatically mean killing. Other factors exists like the obvious rampant poverty and mental illness which gets ignored because it's not as easy to solve and political polarizing than simply banning something.
Why do people say such unsubstantiated nonsense. Places with guns have more death. And it's obvious to see why guns are a tool for for killing, and they're pretty effective.
