Circular saws, arc welding torches, or fork lifts, are not designed to take lives, but to do dangerous work. Guns, however, have the specific function of ending a life, and “gross negligence” in that context, failing to verify that the gun was cold, and cavalierly pointing it at someone, ever, is inexcusable. He could have “rehearsed” with his finger.
