You figure Wynona Ryder is competent to break open a revolver and tell if it’s properly loaded? In this instance, AB was screwing around. He ought to be culpable. Generally speaking, film productions using firearms need a person that knows firearms, and enforces safety protocols like a Nazi. There will be plenty of blame to go around, criminally and civilly.
HollyWeird either needs to stop using gunz to make money or embrace making everyone involved there heavily fund and take NRA gun safety courses along with publicly supporting the 2nd A.
“AB was screwing around...”
I think THAT is the essence/crux of the situation.
He’s totally culpable for his actions.
