“The armorer also indicated that the Assistant Director should not have handed Baldwin the weapon. Only the armorer should have handed it to him. Also, she should never have let it out of her sight. Presumably, the way it was handled on “Rust” someone could replace the gun or load a bullet into it, and it might be hard to determine who did it.”
You add labor disputes and someone might have been just trying to sabotage the filming. They might have thought nobody would point a gun directly at anyone and pull the trigger. I wonder if everyone who worked on the film has to take lie detector tests? Also suspect police are checking ammo purchases in this caliber.
the fingerprint of who ever loaded the round is on the bullet casing.
