[The Pack Knight]

I should modify that: If it was something other than live ammunition, then perhaps there is scenario where Baldwin is purely innocent. But I am hard pressed to imagine what other than live ammo could kill one person and put a second in the hospital.

I agree - had to be a live round. I suppose one other aspect of this is that he was the producer as well, and so should have known if there were other parts of the movie in which live rounds were being used.

That might be the key issue. If they were also using those guns to fire live rounds, and so there were live rounds actually on set, then his degree of caution should have been greatly elevated. But if there were no live rounds being used at all, then this almost amounts to murder by whomever brought them to the set and out them in that gun.
