Don't call me Shirley - thanks for the response. I probably shouldn't have bothered commenting initially and I certainly won't comment again on this thread, but I'll have one final go at explaining my point.
You may well be right that it was inappropriate for Sammie to use that figure in her argument. I don't know and I don't care. I had no interest in bolstering her argument or otherwise. The one and only point that I was trying to make is that, regardless of the appropriateness of using that statistic in her argument, 100,000 is not a ridiculous over-estimate of the number of Americans who are injured or killed by a gunshot in a typical year.
