Also I’m sure she didn’t purchase the ammo for the set. Lots of people were saying she should have known by just by looking at the ammo because it would have a crimp. Wrong. According to the expert the dummy rounds look identical.
Seems like someone would figure out that a dummy round loaded in a pistol could have a pretty big hole drilled in the case. Nobody will see the side.
“Also I’m sure she didn’t purchase the ammo for the set.”
That’s literally her job as the armorer. Just like she had to purchase the guns, complete with 4473 forms. She carries a ton of criminal responsibility here.
The guns are provided by companies in California that specialize in guns for movies.
Just as you cannot ship a gun to another person or company in another state, they cannot either. They ship to an FFL in the state where the movie will be made. The armorer as the agent for the legal entity in that state (the production company) goes to the gun store, does a multiple firearm 4473, and leaves with the guns.
The process goes in reverse when they are done.
Basically, this girl was operating as an underground FFL when she let other people go leave with them. And yes, it’s her job to purchase that ammo.
