This is one that we covered not too long ago, and is a really great example of quick-acting movements by an armed citizen while at work.
John over at ASP recently posted his walk-through of the incident, and touches on all the important parts of this self-defense shooting.
The surveillance video with this shooting is sure to be used in classroom settings around the Country, because it demonstrates a whole lot in such a small amount of time.
Give the video a watch, and let us know how you think this concealed carrier handled the threat presented to him.
