While I might be able to agree that this woman doesn't appear to be the sharpest knife in the drawer, and was in over her head. From what I've read she was not the person to hand that gun to Baldwin and declare it, "cold".
It was handled and declared "cold" by at least one other person beyond her control, before it got passed off to Baldwin... (Who claimed he never pulled the trigger). How many rules of safe gun handling were broken here? And I don't give a damn about, "That's the armorer's job, because that's what they are there for!"
Would you bet someone else's life on that? Alec Baldwin, (regardless if you love him or hate him), is an accomplished actor, who has appeared in numerous westerns. And he has handled many weapons, (not "prop guns"), on the set like the one he fired and killed Hutchinson with. Regardless of who you are, it's up to the individual handling that weapon to check it. Especially if it was handed to him by someone other than the on set armorer.
This woman may be guilty of negligence to a certain degree. (And even that isn't a given). But certainly not a felony conviction of involuntary manslaughter. That carries a possible sentence of years in prison. That's bullshit served on a silver platter. Nothing more.
