That my friend is a good question since only one person was dead.
He pulled the trigger. Someone else loaded the gun.
I read ALL of the stories on this and one of them leaped out at me. There was one story where one of the actors on set with some other people were doing target shooting with the prop guns. This is a big BIG no no in the business. Nobody does any range time with the prop firearms purely for the simple fact that accidents can and do happen.
So why Alec Baldwins gun in particular? Also, why that specific cinematographer? Could be because her husband was a lawyer that happened to be working for a law firm that was being looked at with things in connection to Hillary Clinton? Because that is exactly who her husband was.
What kind of logistics would it take to arrange an assassination to send a message?
Well, it takes a phone call or two to find out what they are shooting for the next days shots and roughly what times. An on set director and armorer would know that shooting schedule as they would have to be on set to re-load firearms for each scene.
So who has access to the firearms? Directors, and armorers. Thats supposed to be it. The likelihood that this firearm was sabotaged or armed with a live rounds is extremely high and that this was not an accident. Especially when the armorer and director in question had questionable activities on previous movie sets.
If I had to bet money, its someone who did not like Alec Baldwin who wanted to send a message that he might not be Mr. Perfect after all. That is my best case scenario because this was clearly not an accident. Nothing like this happens without someone wanting it to. Jobs in Hollywood are so cool that the majority of people doing them rarely if ever get paid what they are worth. Nobody is going to fuck up that kind of job. Even extras dont ever want to fuck up a job like that.
This was done on purpose. Someone wanted to course correct Alec Baldwin. The question in my mind is who.
Not by any means defending Alec Baldwin, but my take is that it basically comes down to the fact that Hollywood is filled with careless, incompetent idiots with over-inflated egos. Are you familiar with the death of Brandon Lee? Seems similar.
