By itself, a firearm is an inert object. By itself, it doesn't just "go off." Insert a human being and a negligent discharge can occur when the proper safety rules aren't followed. Although we've all heard the old adage, "Rules are made to be broken", the four universal safety rules explained here are designed to keep you, and everyone around you safe. If there is any exception to these rules, it is only under the strict control of a defensive shooting instructor, a range safety office. For example, in many of the advanced courses hat the USCCA teaches, students will have an opportunity ty practice drills which may include pointing dummy, SIRT, or simulation firearms at each other, but those drills are only allowed under the strict control of a qualified instructor. If in doubt about whether a rule is or should be temporarily violated, ask your instructor or range safety officer!
