Then overlay a map of gun ownership rates over the suicide rates and see if you see the same correlation.
This isn't an intuitive point. There's actual data showing the correlation I've described.
Something you'll also want to explain is why the suicide rate for teens is 3x higher than for adults and why elderly is 2x higher than adults. Or why more than 1/3 of suicides don't involve a gun at all. Or why Japan's suicide rate is so much higher despite having no gun ownership rights.
