Ultimately, Alec Baldwin is the darling of liberal Hollywood and therefore can't be culpable for this mess - despite being primarily and obviously to blame for it from beginning to end.
Alec Baldwin employed Reed despite knowing that she was unqualified and inexperienced. He's producer and ultimately responsible for what happens on set. If you are making a movie that involves a lot of guns and gunplay and you employ someone incompetent in such a key role - it's your fault.
Alec Baldwin ultimately picked up a gun without knowing what was in it, and knowing that it was a real gun (not a fake gun - and the term "prop" as his team have repeatedly used means that it was part of a movie inventory - not that it wasn't a real gun), he pointed it at a member of the crew and he pulled the trigger - when there was no need to do so.
Alec Baldwin lied about this from beginning to end.
The husband of the deceased cinematographer has suddenly become an executive producer on the movie.
This is Hollywood, ladies and gentlemen. The same people that tell you guns are bad and nobody should have them - at the same time as making money from movies about people with guns, and actually killing people with them.
