Not going to speak ill of your family and am happy that she was unharmed.
Fact remains that there have been more people killed, especially good guys because of lacking the proper mindset.
If this was all none sense, there wouldn't be books on top of books, FBI LE lectures which are sold out all the time and seminars for highspeed gov/mil personnel taught logic and mindset.
In my experience those who disregard mindset either haven't been tested to the point of needing to up their game to survive or simply ignorant of the information either due to not having it properly taught to them or not having the understanding of the context.
Now of this is not a indictment of those who lack it, it is simply a fact of reality. By the way, none of the above you can get from competition, in no way, shape or form.
As I've stated before, if a person needs to learn gun handling, shooting accurately or otherwise gain "gun in hand" experience on the range competition is good for that. Is it the only way? No. Is it that best way? Depends on what you do for a living and what your point for having/carrying a gun is.
