Kellerman treated guns like you would treat germs, equating correlation with causation, and did not at all control for other relevant factors. When you can show me how you get a gunshot wound from a dirty doorknob, maybe that will become relevant. 86% of his examples were suicides, and no one has ever provided evidence that owning a gun makes one more likely to commit suicide.
And I DID give you a cite, in the form of Gary Kleck's work. If you want a specific example, try his 1991 book "Point Blank: Guns and Violence in America."
