Happened at a grocery store about 15 miles from me recently. The bad guy ended up dead in a parking lot and the good guy was hailed as a hero by witnesses and law enforcement.
Those kinds of anecdotes aren't really representative of reality. For instance, more gun ownership doesn't really tend to correlate with less gun deaths:

randomized study performed in 1995 with 5,000 participants, one which was
rebuked years later for experimental issues (social desirability bias, for instance, which accounted for the possibility of 99 false-positive reports per every 100 people surveyed, assuming 1% of people end up using their gun defensively). There were also issues with the way the study was randomized, including the fact that over 60% of people answering the phone survey didn't complete it, meaning that it's entirely possible that gun owners strategically committed to completing the survey, being well-aware of the debate over defensive gun use...
Yes, I'm aware of the fact that my post is pretty much an ad-verbatim summary of the abstract of that study. It's not my own original research.
