I think it depends on his behavior in handling the weapon prior to the event and whether he was following any direction from the crew in when to wield, aim, and fire the weapon.
If he was treating it with care and following directions then it’s hard to blame him, I think.
If he was treating it cavalierly and pointing it at people and things on his own, I think he bears some responsibility.
I’m wondering about the propmaster’s (and other responsible figures in the crew, including the director’s) role in all this. If there are live weapons or potentially dangerous props on the set, were the cast and crew instructed in how to handle them properly? Did they have to sign documents assuming responsibility for their use? Were any waivers involved?
I think Baldwin is a skunk who is fully capable of reckless behavior resulting in a tragedy like this. But it needs to be proved in a court if he is to blame.
SNL should have him on this week.
I’m sure they are so proud to have such an idiot represent them.
