For those who like numbers and statistics here is a good read, you will have to have a Face Book account to read it though. (or I think you will)
Overview of Survey
For the period 1997 - 2001, reports from "The Armed Citizen" column of the NRA Journals were collected. There were 482 incidents available for inclusion in the analysis. All involved the use of firearms by private citizens in self defense or defense of others. No law enforcement related incidents were included. The database is self-selecting in that no non-positive outcomes were reported in the column.

The analysis may, however, be useful in helping to describe a methodology for successful armed self-defense. This methodology might be described as:
1. be aware,
2. be willing to fight,
3. have a weapon accessible,
4. be familiar enough with the weapon to employ it without fumbling,
5. when ready, communicate, both verbally and non-verbally, to the attacker that resistance will be given, and
6. if the attacker does not withdraw, counterattack without hesitation.
