You should examine your links a little more thoroughly. The 5 year DOJ report did use documented cases to evaluate murders, but non fatal interactions were gleaned from a survey. A self included survey. In other words. any gun nut was free at any time to report his most recent fantasy of holding off an entire gang of thugs, and there was no effort to verify any of those claims. We both know lots of people who tell stories like that, don't we? Since all the reports that the previous poster, as well as the first of the ones you mentioned were only surveys and not studies, I didn't see any need in bothering with any more.
