When the person firing has some form of malfunction or is confused, and figure the best way to figure out the malfunction is too point the firearm all over creation while looking at the side waiting for a freaking printout from the freaking extractor port or something that will tell them exactly what happened. Happened twice when I took some friends to the range Saturday. And twice I jump up out of my chair saying loudly enough "direction!" for them to realize their mistake. Nothing wrong with the gun either time. Both of them have shot before and clearly know and have practiced the range safety rules but for some reason, when they are confused, all common sense goes out the window and is replaced by some idiotic notion that staring at the gun hard enough will solve the confusion. I am going to tape a note to both sides of all my guns when letting people shoot them. It is going to say "If you are reading this, you are not pointing the gun in the safe direction." What confuses people about the phrase "there is literally nothing more important here than pointing that gun in a safe direction and keeping your finger off the trigger"? I swear, I really want to institute safety infraction beatings as a range sanctioned method of education. Three violations and you get pummelled by the owner of the firearm (unless it was their negligence), the person you pointed it at, and at least one RO with bags of doorknobs. Who is on board with the mandatory beating rule?
