It really isn't their fault, even though it is. CCW courses are the most dangerous ones I've seen. I used to see a lot of them, then I said F- it. There are too many amatuers who think they know how to operate a gun because they BUY firearms. This is one of the reasons for ca2a in the course section, I plan on doing videos as primers for people.
People just don't prioritize handling, the only time they touch is it, is when they bought it and for the class. What we do at the range, is another class of shooter, like getting them ready for road bike racing vs just getting your license. But we can bring the techniques down, and offer it for free via video learning.
My goal is to get people to watch the videos prior to taking a class because experiences like @CadeH is very common. That's why static line ranges are the worst. Don't get me wrong though, I see a lot of ND's and other handling mistakes by regular people and 180'd myself in a match. It happens, just gotta minimize it. CCW people though man, you can def tell who got it to be cool vs people who got it for work by what they wear.
