I’d guess there’s a lot more to this story.
Ok... a prop would be a fake gun.
This on the other hand would be a gun that was being used to make a video not a gun that was being used as a prop.
I’ve been around enough Community Theater and pit crew stuff to know what they use in the theatrical productions.
I agree. A great deal more. He did not accidentally get killed by a prop. Note that the story said it occurred at his apartment.
