Nothing personally, but I've known a couple who found that when the stuff hit the fan, they were unable to react so they quit carrying. My son often had people ether walk out of his classes on the first day during classroom portion or as late as range day.
I am glad they quit carrying and the class even though it is a mindset that I can in no way, shape, or form understand but I have seen it myself. :confused3:
Once upon a time, I was in a defensive tactics class and the instructor asked how many people in the class could use deadly force? He phrased the question in such a way that all uncertainties of making a mistake were out of the way. The scary result was that only about 1/3 of the class raised their hands.

:shocked: I was shocked. If you were in that class and NOT raising your hand you had two choices as far as I was concerned, turn in your gear and go home or have a come to Jesus meeting real quick with yourself. Nobody quit which I think was unfortunate because I do not think that all of the uncertain group got right with themselves either.

They were a danger to themselves and the public.
There is a video from a dash camera where a young police officer was chasing a truck. Long story short, is that the officer had every reason and right to shoot the truck driver but failed to do so and the officer died as a result. The officer had plenty of time to shoot but did not. We will never know why the officer did not shoot, fear of lawsuits, fear of doing the right/wrong thing, fear of shooting someone or some combination there of. What is certain is that he did not shoot, and instead, he was shot and killed. My strong guess is that he simply could not shoot someone to defend himself. So he died.
Marshal, Grossman, Holmes, Keegan, etc talk about this in depth. Course, I think the Old Testament touches on the subject as well.
