Yeah you never see actors take extensive fire arms courses or martial arts training, they literally just show up and act lol
If this incident had involved Keanu Reeves then it might be perceived a bit differently. Anyway, I haven't at any point claimed that the actor is completely blameless in this situation (maybe Alec Baldwin also messed up by pointing it and pulling the trigger when he did) I've questioned the seemingly popular idea in this thread that once an actor has been told a prop gun is safe, they are expected to open it up and check the ammo for themselves.
