And don’t point a gun at anyone unless you intend to shoot them… this is manslaughter at a minimum and he needs to be charged.
Movie sets are a special case. During active filming and dry run rehearsals firearms are routinely pointed at across by actors that’s part of the industry. The armor and directors job and legal responsibility is to ensure that protocol is followed and the weapons are cold weapons. The armor and acting director on this scene probably will face negligence charges the actor is not in the chain of ensuring the weapon is cold in most sets. It is common practice to point and even fire live blanks at greater than 15 feet at live humans. I personally have done this during theater performance another instance where it is normal to fire an otherwise functional firearm at a human with blanks triple checked as such.
