for the reasons she died which was not that Baldwin pulled the trigger, he had to. It's how the live round found it's way to that Pietta SAA clone.
I am going to dispute this, slightly...
The live round getting into the gun is the primary contributing factor. And, if it had been absent then no one would have been shot, this is true.
But the live round was what did the work, not the reason she died. She died because Baldwin shot her.
This was not a case of an actor pointing a gun and "firing" it at a cast member because the script called for it. This was Baldwin screwing around, pointing a gun at a crewmember (NOT an actor on the set) cocking the gun and whether he remembers doing it or not, he must have pulled the trigger.
OF course he thought the gun was harmless, he had been told so, but he just assumed it was because he was told it was and he KNEW proper procedure had not been followed.
Much has been said about how actors aren't expected to be firearms experts, and not required to be. But what they are expected to be is experts at their own jobs, and I've been watching Baldwin use guns in the movies for over 30 years.
He HAD to have known that the proper protocols had not been followed, and he didn't care. He got what he wanted, when he wanted, he was the boss and following the rules wasn't done if it got in the way of what he wanted and wanted "right now!". And "everything was fine" until his cinematographer got shot...
Its not the actor's "job" to point guns and pretend to shoot the crew members. It is part of the actor's job to witness the gun to be used being loaded, so that they know it IS loaded, and what it is loaded with. Baldwin did neither.
