Even if there was a mandatory law that forced gun owners to attend and pass safety and self defense courses, We all know that everything goes out the door when under stress unless you practice, practice, practice. Taking a one day safety course and then bringing your brand new weapon home, whereupon you then place it in a lock box and hide it in the closet, never again to see it until confronted by an intruder, is a disaster waiting for the time of need.
The average police officer in this country attends a two week retraining course once a year. One day of re qualification at the range. Really this training does little or nothing, to insure that the officer will act properly under stress. I've been there and done that. What you see brother officers do under stress is sometimes worse than what is witnessed here.
I know it bugles the mind of folks who handle firearms regularly, and especially those who are instructors. But then most instructors are ingrained to observe every incident with an eye towards correctness, and can't help critiquing these incidents.
While these two folks made a lot of mistakes, I admire their spunk. Right now, they are America's hero's, in the eyes of most of us.
