Which is why this happened. Hollywood thinks they are "special" and above the rules that apply to everyone else handling a firearm whether it taking it out of the safe to clean it, at a store, at the range, or on duty. The point is they are not above the rules. Had they followed the 12 golden rules we wouldn't be having this discussion.

That means actors and anyone handling a firearm are given training on the mechanical function of the guns, how to load/unload, and do a safety check.

Something that is driven home in every defensive shooting class, every CCW class, every hunters ed class is that ultimately the person who pulls the trigger is the person who bears responsibility for what comes out of the barrel.
