They're trying to shift blame away from Baldwin, but he held the gun, and he had the ultimate responsibility to ensure it was safe to be used in the way he used it.

Had he ever received any gun safety education? Certainly that too would have been his responsibility to ensure as the film's producer. I'm not concluding anything, but it's not difficult to imagine that anti-gun zealot Baldwin was personally offended by the very idea of receiving any firearm related training.
