All that explanation sounds great, but it has little to do with NM statutes on the discharge of a firearm resulting in death. Baldwin faces (or should be facing, in a sane world where law treats everyone equally) that fact that under NM law, he discharged a firearm resulting in death and grave bodily harm.
Since he didn’t intentionally pull the trigger. This has to be an accidental discharge or mechanical failure leading to discharge. The negligence is on the armor first and foremost for handing a live round in the chamber to an actor on set then declaring cold gun. That changes the legal dynamic considerably. Actors are not qualified, tasked nor expected to second guess their professional armors this has a long standing legal precedence. Don’t let politics blind you to facts. The actor th at shot Brandon Lee was never charged why? Because the armor failed to clear the gun , declared it a cold gun and when the gun went off the bullet still in the guns barrel from an earlier scene flew out and killed Brandon Lee. The actor was not expected then nor would they be now to know to clear a weapon that’s the armor job and legal responsibility.
