For More Guns, Less Crime, The Bias Against Guns, and some of my op-ed pieces I have at least partially relied upon Nexis/Lexis searches to discover defensive gun uses, but that method is very time consuming and it is not available to everyone. This blog collects stories here.
Fortunately, there are a few other sites that I reference for defensive gun uses. One that provides an excellent search engine for types of cases is provided at goodguyswin.org, a list of the most recent cases is available at keepandbeararms.com, and some fairly old cases can be found on the NRA site. The search engine at goodguyswin.org is very powerful, but the references there tend to be at least a few months old. The NRA used to also have a section on more recent cases (and they probably still do someplace), but I haven't been able to find it since they have revamped their website. A new site that I just saw very recently is by Clayton Cramer and David Burnett, though there appears to be a lot of overlap with the keepandbeararms.com web site.
