It’s a case of criminal negligence, IMHO.
Why were live rounds being used? Why weren’t they using a specialized prop gun that was incapable of firing live rounds? How did the cinematographer get into the line of fire? How could he shoot TWO people with the gun
Alex Baldwin himself shouldn’t escape responsibility. It was he who fired the weapon, obviously without personally checking for live rounds.
Not criminal negligence. It’s not possible to accidentally load a live round into a prop pistol. This is murder.
Whoever did it, it’s murder. Just a question of who and why. We already have a maniac on the set who is the prime suspect.
