Absent more, I am in this camp as well. It seems to me like the key question is one of law: was it negligent for Baldwin to point a gun at someone on set while preparing for (but not actually filming) a scene?
The factual question, did Baldwin pull the trigger? is almost moot to me. I leave that qualifier, “almost”, in there only to accommodate the possibility that someone might be able to explain why, in this situation, pointing a gun at someone was totally okay, but pulling the trigger was not. Even though the whole reason that part of the safety instructions for us non-specials who don’t make movies is “never point a gun at anything you do not intend to shoot.”
And I get it. There is a large camp that believes the standard safety rules cannot reasonably apply on set. Maybe that’s as it should be (although I don’t take it for granted). However, if, for the sake of argument, it is acceptable to point a gun at someone on set in either filiming or preparing to film a scene that requires certain motions with the gun, then I think that implies it may be acceptable to pull the trigger as well, particularly as some guns might, particularly when the hammer is already drawn back (was it here?) have a very light trigger, such that even a slight, accidental brush of the trigger (maybe by getting caught on part of a glove- was Baldwin wearing gloves? IDK, just positing ideas here) could be enough to depress it and case the hammer to fall.
Point being, once you remove the safety factor that consists of “never point a gun at anything you don’t intend to shoot,” you have implicitly also removed the safety factor (inherent in the other one) of “don’t pull the trigger while pointing the gun at anything you don’t intend to shoot.” Because it’s a lot easier to accidentally, perhaps even without realizing it, pull the trigger and shoot something (or someone) once you’re already pointing the gun in that direction.
