How about the assistant director, who took a plea deal? He was the last one to inspect the gun before Baldwin fired it.
I think this is what is going to get Hanna, (Thell Reed's daughter, and the armorer), off the hook. She has been charged as well. Regardless of what she did, or didn't do. Or what she should have done,
she was NOT the last one to handle that weapon. It passed through at least 2 other peoples hands after she last touched it, (Dave Hall, and Baldwin himself).
And Dave Hall declared the weapon "cold" just before he handed it to Baldwin. (This he himself admitted in police interviews). So regardless of how careful she was or wasn't, she cannot be held responsible for any weapon that continues to be handled by others before it discharges, killing one and wounding another.
Looking at this whole thing in that context, I can't believe he was even offered a plea deal. He is far more "convictable" than she is. Based on the fact of his admission the gun was "cold" when it was not. Why would you declare a weapon as such, without personally inspecting it yourself? If he had, he would have found the live rounds, and this never would have happened.
