Very often, I hear people saying "I really need to take a class in that" when we talk about self-defense, firearms, and actual arms-length confrontations.
People hear about real-life situations that have occurred, we talk a little bit around tactics, movement, and technique, we discuss some scenario training, they maybe have seen a couple of YouTube videos of people moving around a bit---and they say "I really need to take that class."
But they don't.
They know the information is something they lack. They know they wouldn't understand the situation, what would have to be done, and what they could do about it if it occurred. They realize that they don't have any practice at useful techniques for staying alive at that range, or protecting their loved ones at that range.
But they still don't take the class.
That's up to them, of course. Statistically speaking, it IS true that it is unlikely that a normal, law-abiding citizen is going to need to defend themselves with lethal force.
If the dice get rolled and it comes up snake-eyes, though, I hope for your sake that the attacker is nice enough, while threatening you with lethal force, to stay more than 5 yards away from you instead of being right IN YOUR FACE.
Seriously. I hope it works out for you.
And truthfully, the odds are that you'll never need ANY of these techniques--because you won't even need your gun. Because that level of problem simply won't happen to you.
Of course, if you carry in the first place, you are the type of person that thinks "being prepared and not needing it is better than NOT being prepared and needing it."
So----why aren't you taking this class?
