Kellerman and Reay: "Protection or peril? An analysis of firearm deaths in the home." N.E. Journal of Medicine, 1986
Has often been quoted as asserting that one is 43 times more likely to kill themselves or someone close to them than to kill a criminal in self-defense (somewhat paraphrased, but then that's the way it's been stated zillions of times by anti-gun types).
Of the 43 times factor, 37 was suicide.
In all cases, someone had to die to be part of the statistic (scaring or warning away, or even *wounding* an assailant got zero points in this study).
If you take out the suicides and just go with being 6 times more likely, one should then compare this to other ways one might die at home. I did this once (using CDC statistics), and gun deaths were trumped (don't recall by how much, but it was more than a few percent) by FALLING DOWN! (e.g. the stairs).
Try the math - at the least it would be amusing. And it might be enlightening.
This "guns are so dangerous" meme is a fabrication when viewed statistically. Every death is a tragedy. But tragedy happens a lot, and guns are not the majority of source of tragedy (notwithstanding tyrannical dictatorships, genocide, etc.)
