Hollywood movie industry doesn’t write law. New Mexico law says Baldwin was being negligent, and that negligence resulted in some one’s death. This is a crime.
If a lawyer tells you it’s okay to go 80 in a 55, and a cop writes you a speeding ticket, you don’t get to pull “advice of counsel” as a defense to get out of it, because the lawyers advice is obviously unreasonable and incorrect.
Alternatively, if you call a mechanic and describe some brake symptoms and he says it’s safe to get it into the shop without a tow, and you get into an accident because the brakes failed… the mechanic is not liable for that, ultimate liability rests with the driver. The mechanic didn’t know the full circumstances.
Similarly, even an idiot could be reasonably expected to recognize that it’s unsafe to point a functional firearm at people and pull the trigger (or otherwise waive it around like a toy.) therefore, an expert’s advice to the contrary is quite unreasonable and on its own face should have been ignored; and HGR was unaware of his actions with the weapon as she was not immediately present.
Therefore, Baldwin failed a duty of care to behave in a safe manner (aka he was negligent,) and some one died (homicide- probably invol. Manslaughter or whatever the specific term is.) It also goes out the window when you recognize that HGR was in fact not an expert. She was a laughably inexperienced neppo-baby and we all know it. (She was also hired because she was inexperienced and allowed things that she should not have. This benefitted the production by reducing slow downs in filming.
Now to the second point:
Baldwin did not receive the weapon from HGR- he received from an assistant producer (who plead guilty, too.)
