Right!...through all of that training I have learned that ...the gun is no panacea,
First, a quick aside: according to Attorney Andrew Branca. FBI stats tell us that some 75% of the criminal confrontations that occur do not rise to the level at which the use of deadly force (and in most jurisdictions, even the threat of deadly force) is lawfully justified. That means that in addition fo carrying a firearm, one would be very well served to carry a less-than-lethal defensive tool, also. In my case, I always have with me a strong walking stick--which, by the way, seems to serve as a deterrent.
Now to the point: self defense involves a whole lot more than using force. It involves avoiding the need if possible, detecting the need timely if necessary, and reacting to the need effectively if it does come to that.
Defensive pistol training is not "learning to shoot". In my first course, put on by the Texas Defensive Shooting Association, I was amazed to learn how quickly one should be able to shoot in a defensive shooting situation. The target does not stand still, the distances are close, and one-shot stops are most common in screen fiction.Students first fired 800-1200 rounds doing nothing but improving their speed on steel plates before doing anything else.
In Pincus' course, the emphasis was on quick reaction to a threat that we had not been expecting, attacking from a direction that we had not been facing. It was not about "going shooting". The need to reach a balance of speed and precision appropriate for the situation was emphasized. A group smaller than the area of the upper chest at a distance of a dozen feet could well mean that the defender was shooting to slowly.
By the way, after that course I never rounded the corner when going to may car around a building, or walked past a corner, in quite the same way again.
Another excellent resource is the The Best Defense TV series. All kinds of situations, based on real events, are portrayed, along with how to try to come out of them alive. Some are real eye-openers. They are not making any new ones, but it would be worth finding a source of re-runs or recordings.
They surely taught me a lot.
